The basic unit of length in the modern version of the metric system, known as the International System of Units (SI). It is equivalent to 39·37 inches.
Large axons are covered by a sheath of insulating myelin which is interrupted at intervals by nodes of Lanvier, where other axons branch out. An axon may be more than a metre long. It ends by branching into several ?laments called telodendria, and these are in contact with muscle or gland membranes and other nerves (see NERVE).... axon
closer than 6 metres away, the rays of light from this near object will be diverging by the time they reach the eye. In order to focus these diverging beams of light, the refracting power of the lens must increase. In other words the lens must accommodate.
The lens loses its elasticity with age, and thus becomes less spherical when tension in the zonule relaxes. This results in an increased longsightedness (presbyopia) requiring reading glasses for correction. (See AGEING.)... accommodation
The so-called ultra-short-wave diathermy (or short-wave diathermy, as it is usually referred to) has replaced the original long-wave diathermy, as it is produced consistently at a stable wave-length (11 metres) and is easier to apply. In recent years microwave diathermy has been developed, which has a still higher oscillating current (25,000 million cycles per second, compared with 500 million for short-wave diathermy).
When the current passes, a distinct sensation of increasing warmth is experienced and the temperature of the body gradually rises; the heart’s action becomes quicker; there is sweating with increased excretion of waste products. The general blood pressure is also distinctly lowered. The method is used in painful rheumatic conditions, both of muscles and joints.
By concentrating the current in a small electrode, the heating effects immediately below this are very much increased. The diathermy knife utilises this technique to coagulate bleeding vessels and cauterise abnormal tissue during surgery.... diathermy
Divisions The intestine is divided into small intestine and large intestine. The former extends from the stomach onwards for 6·5 metres (22 feet) or thereabouts. The large intestine is the second part of the tube, and though shorter (about 1·8 metres [6 feet] long) is much wider than the small intestine. The latter is divided rather arbitrarily into three parts: the duodenum, consisting of the ?rst 25–30 cm (10–12 inches), into which the ducts of the liver and pancreas open; the jejunum, comprising the next 2·4–2·7 metres (8–9 feet); and ?nally the ileum, which at its lower end opens into the large intestine.
The large intestine begins in the lower part of the abdomen on the right side. The ?rst part is known as the caecum, and into this opens the appendix vermiformis. The appendix is a small tube, closed at one end and about the thickness of a pencil, anything from 2 to 20 cm (average 9 cm) in length, which has much the same structure as the rest of the intestine. (See APPENDICITIS.) The caecum continues into the colon. This is subdivided into: the ascending colon which ascends through the right ?ank to beneath the liver; the transverse colon which crosses the upper part of the abdomen to the left side; and the descending colon which bends downwards through the left ?ank into the pelvis where it becomes the sigmoid colon. The last part of the large intestine is known as the rectum, which passes straight down through the back part of the pelvis, to open to the exterior through the anus.
Structure The intestine, both small and large, consists of four coats, which vary slightly in structure and arrangement at di?erent points but are broadly the same throughout the entire length of the bowel. On the inner surface there is a mucous membrane; outside this is a loose submucous coat, in which blood vessels run; next comes a muscular coat in two layers; and ?nally a tough, thin peritoneal membrane. MUCOUS COAT The interior of the bowel is completely lined by a single layer of pillar-like cells placed side by side. The surface is increased by countless ridges with deep furrows thickly studded with short hair-like processes called villi. As blood and lymph vessels run up to the end of these villi, the digested food passing slowly down the intestine is brought into close relation with the blood circulation. Between the bases of the villi are little openings, each of which leads into a simple, tubular gland which produces a digestive ?uid. In the small and large intestines, many cells are devoted to the production of mucus for lubricating the passage of the food. A large number of minute masses, called lymph follicles, similar in structure to the tonsils are scattered over the inner surface of the intestine. The large intestine is bare both of ridges and of villi. SUBMUCOUS COAT Loose connective tissue which allows the mucous membrane to play freely over the muscular coat. The blood vessels and lymphatic vessels which absorb the food in the villi pour their contents into a network of large vessels lying in this coat. MUSCULAR COAT The muscle in the small intestine is arranged in two layers, in the outer of which all the ?bres run lengthwise with the bowel, whilst in the inner they pass circularly round it. PERITONEAL COAT This forms the outer covering for almost the whole intestine except parts of the duodenum and of the large intestine. It is a tough, ?brous membrane, covered upon its outer surface with a smooth layer of cells.... intestine
Sneezing may be caused by the presence of irritating particles in the nose, such as snu?, or the pollen of grasses and ?owers. It is also an early symptom of colds, INFLUENZA, MEASLES, and HAY FEVER, being then accompanied or followed by running at the nose (RHINITIS).... sneezing
Sensory These carry signals to the central nervous system (CNS) – the BRAIN and SPINAL CORD – from sensory receptors. These receptors respond to di?erent stimuli such as touch, pain, temperature, smells, sounds and light.
Motor These carry signals from the CNS to activate muscles or glands.
Interneurons These provide the interconnecting ‘electrical network’ within the CNS.
Structure Each neurone comprises a cell body, several branches called dendrites, and a single ?lamentous ?bre called an AXON. Axons may be anything from a few millimetres to a metre long; at their end are several branches acting as terminals through which electrochemical signals are sent to target cells, such as those of muscles, glands or the dendrites of another axon.
Axons of several neurones are grouped
together to form nerve tracts within the brain or spinal cord or nerve-?bres outside the CNS. Each nerve is surrounded by a sheath and contains bundles of ?bres. Some ?bres are medullated, having a sheath of MYELIN which acts as insulation, preventing nerve impulses from spreading beyond the ?bre conveying them.
The cellular part of the neurones makes up the grey matter of the brain and spinal cord – the former containing 600 million neurones. The dendrites meet with similar outgrowths from other neurones to form synapses. White matter is the term used for that part of the system composed of nerve ?bres.
Functions of nerves The greater part of the bodily activity originates in the nerve cells (see NERVE). Impulses are sent down the nerves which act simply as transmitters. The impulse causes sudden chemical changes in the muscles as the latter contract (see MUSCLE). The impulses from a sensory ending in the skin pass along a nerve-?bre to affect nerve cells in the spinal cord and brain, where they are perceived as a sensation. An impulse travels at a rate of about 30 metres (100 feet) per second. (See NERVOUS IMPULSE.)
The anterior roots of spinal nerves consist of motor ?bres leading to muscles, the posterior roots of sensory ?bres coming from the skin. The terms, EFFERENT and AFFERENT, are applied to these roots, because, in addition to motor ?bres, ?bres controlling blood vessels and secretory glands leave the cord in the anterior roots. The posterior roots contain, in addition to sensory ?bres, the nerve-?bres that transmit impulses from muscles, joints and other organs, which among other neurological functions provide the individual with his or her
proprioceptive faculties – the ability to know how various parts of the body are positioned.
The connection between the sensory and motor systems of nerves is important. The simplest form of nerve action is that known as automatic action. In this, a part of the nervous system, controlling, for example, the lungs, makes rhythmic discharges to maintain the regular action of the respiratory muscles. This controlling mechanism may be modi?ed by occasional sensory impressions and chemical changes from various sources.
Re?ex action This is an automatic or involuntary activity, prompted by fairly simple neurological circuits, without the subject’s consciousness necessarily being involved. Thus a painful pinprick will result in a re?ex withdrawal of the affected ?nger before the brain has time to send a ‘voluntary’ instruction to the muscles involved.
Voluntary Actions are more complicated than re?ex ones. The same mechanism is involved, but the brain initially exerts an inhibitory or blocking e?ect which prevents immediate re?ex action. Then the impulse, passing up to the cerebral hemispheres, stimulates cellular activity, the complexity of these processes depending upon the intellectual processes involved. Finally, the inhibition is removed and an impulse passes down to motor cells in the spinal cord, and a muscle or set of muscles is activated by the motor nerves. (Recent advances in magnetic resonance imaging (MRI) techniques have provided very clear images of nerve tracts in the brain which should lead to greater understanding of how the brain functions.)

Grade of obesity
BMI (W/H2) III >40 II 30–40 I 25–29·9 not obese <25
Causes Whatever the causes of obesity, the fact remains that energy intake (in the form of food and drink) must exceed energy output (in the form of activity and exercise) over a suf?ciently long period of time.
Obesity tends to aggregate in families. This has led to the suggestion that some people inherit a ‘thrifty’ gene which predisposes them to obesity in later life by lowering their energy output. Indeed, patients often attribute their obesity to such a metabolic defect. Total energy output is made up of the resting metabolic rate (RMR), which represents about 70 per cent of the total; the energy cost of physical activity; and thermogenesis, i.e. the increase in energy output in response to food intake, cold exposure, some drugs and psychological in?uences. In general, obese people are consistently found to have a higher RMR and total energy output, per person – and also when expressed against fat-free mass – than do their lean counterparts. Most obese people do not appear to have a reduced capacity for thermogenesis. Although a genetic component to obesity remains a possibility, it is unlikely to be great or to prevent weight loss from being possible in most patients by reducing energy intake. Environmental in?uences are believed to be more important in explaining the familial association in obesity.
An inactive lifestyle plays a minor role in the development of obesity, but it is unclear whether people are obese because they are inactive or are inactive because they are obese. For the majority of obese people, the explanation must lie in an excessive energy intake. Unfortunately, it is di?cult to demonstrate this directly since the methods used to assess how much people eat are unreliable. For most obese people it seems likely that the defect lies in their failure to regulate energy intake in response to a variety of cognitive factors (e.g. ease of ?tting of clothes) in the long term.
Unfortunately, it can be possible to identify by the time of their ?rst birthday, many of the children destined to be obese.
Rarely, obesity has an endocrine basis and is caused by hypothyroidism (see under THYROID GLAND, DISEASES OF), HYPOPITUITARISM, HYPOGONADISM or CUSHING’S SYNDROME.
Symptoms Obesity has adverse effects on MORBIDITY and mortality (see DEATH RATE) which are greatest in young adults and increase with the severity of obesity. It is associated with an increased mortality and/or morbidity from cardiovascular disease, non-insulin-dependent diabetes mellitus, diseases of the gall-bladder, osteoarthritis, hernia, gout and possibly certain cancers (i.e. colon, rectum and prostate in men, and breast, ovary, endometrium and cervix in women). Menstrual irregularities and ovulatory failure are often experienced by obese women. Obese people are also at greater risk when they undergo surgery. With the exception of gallstone formation, weight loss will reduce these health risks.
Treatment Creation of an energy de?cit is essential for weight loss to occur, so the initial line of treatment is a slimming diet. An average de?cit of 1,000 kcal/day (see CALORIE) will produce a loss of 1 kg of fat/week and should be aimed for. Theoretically, this can be achieved by increasing energy expenditure or reducing energy intake. In practice, a low-energy diet is the usual form of treatment since attempts to increase energy expenditure, either by physical exercise or a thermogenic drug, are relatively ine?ective.
Anorectic drugs, gastric stapling and jaw-wiring are sometimes used to treat severe obesity. They are said to aid compliance with a low-energy diet by either reducing hunger (anorectic drugs) or limiting the amount of food the patient can eat. Unfortunately, the long-term e?ectiveness of gastric stapling is not known, and it is debatable whether the modest reduction in weight achieved by use of anorectic drugs is worthwhile – although a new drug, ORLISTAT, is becoming available that reduces the amount of fat absorbed from food in the gastrointestinal tract. For some grossly obese patients, jaw-wiring can be helpful, but a regain of weight once the wires are removed must be prevented. These procedures carry a risk, so should be done only if an individual’s health is in danger.... obesity
A single virus particle, known as a virion, comprises an inner core of NUCLEIC ACID which is surrounded by one or two protective coverings (capsid) made of protein. Sometimes the capsid is enclosed by another layer called the viral envelope (also a protein structure). The envelope often disintegrates when the virus invades a cell. Viruses enter cells and then indulge in a complex and variable process of replication using some of the cells’ own structure. Viruses may stay in a host’s nucleus, being reactivated months or years later. There are more than a score of large families of viruses, from papoviruses, which cause WARTS, through HERPES viruses (cold sores, CHICKENPOX, SHINGLES) and orthomyxoviruses (in?uenza), to corona viruses (common cold) and retroviruses (AIDS/HIV). Viral diseases are more dif?cult to treat than those caused by bacteria: ANTIBIOTICS are ine?ective but INTERFERON, a group of natural substances, shows promise. IMMUNISATION is the most e?ective way of combating viral infections; smallpox, poliomyelitis, MUMPS, MEASLES and RUBELLA are examples of viral diseases which have been successfully combated. Research is progressing to ?nd a vaccine against HIV.... virus
Pathway of light from the eye to the brain Light enters the EYE by passing through the transparent cornea, then through the aqueous humour ?lling the anterior chamber. It then passes through the pupil, through the lens and the vitreous to reach the retina. In the retina, the rod and cone photoreceptors detect light and relay messages in the form of electrochemical impulses through the various layers of the retina to the nerve ?bres. The nerve ?bres carry messages via the optic nerve, optic chiasma, optic tract, lateral geniculate body and ?nally the optic radiations to the visual cortex.
Here in the visual cortex these messages are interpreted. It is therefore the visual cortex of the BRAIN that ‘sees’.
Visual acuity Two points will not be seen as two unless they are separated by a minimum distance. This distance is such that the objects are so far apart that the lines joining them to the eye enclose between them (subtend) an angle of at least one minute of a degree. This amount of separation allows the images of the two points to fall on two separate cones (if the light from two points falls on one cone, the two points would be seen as a single point). There are many tests of visual acuity. One of the more common is the Snellen test type. This is made up of many letters of di?erent size. By conventions the chart is placed 6 metres away from the patient. Someone able to see the lowest line at this distance has a visual acuity of 6/4. If they are only able to see the top letter they have 6/60 vision. ‘Normal’ vision is 6/6.
Colour vision ‘White light’ is made up of component colours. These can be separated by a prism, thereby producing a spectrum. The three cardinal colours are red, green, and blue; all other colours can be produced by a varying mixture of these three. Colour vision is a complex subject. The trichromat theory of colour vision suggests that there are three types of cones, each type sensitive to one of the cardinal colours. Colour perception is based on di?erential stimulation of these cone types. The opponent colour theory suggests that each cone type can generate signals of the opposite kind. Output from some cones can collaborate with the output from others or can inhibit the action of other cones. Colour perception results from these various complex interactions.
Defective colour vision may be hereditary or acquired, and can occur in the presence of normal visual acuity. HEREDITARY DEFECTIVE COLOUR VISION is more common in men (7 per cent of males) than women (0·5 per cent of females). Men are affected, but women convey the abnormal gene (see GENES) to their children. It occurs because one or more of the photopigments of the retina are abnormal, or the cones are damaged. Red-green colour defect is the most common. ACQUIRED DEFECTIVE COLOUR VISION is the result of disease of the cones or their connections in the retina, optic nerve or brain – for example, macular disease, optic neuritis. Col-our vision can be impaired but not lost as a result of corneal opaci?cation or cataract formation (see under EYE, DISORDERS OF).
TESTS OF COLOUR VISION These use specially designed numbers made of coloured dots surrounded by dots of confusing colour (e.g. plates).... vision
The energy needed to keep the body functioning at rest is called the basal metabolic rate (BMR). It is measured in joules (or kilocalories) per square metre of body surface per hour. The BMR increases in response to factors such as stress, fear, exertion, and illness, and is controlled principally by various hormones, such as thyroxine, adrenaline (epinephrine), and insulin. (See also metabolism, inborn errors of; metabolic disorders.)... metabolism
Weight loss or weight gain occurs if the net balance is disturbed.
Weight can be compared with standardized charts for height, age, and sex. At all ages, divergence from the normal weight for height may have medical implications. For example, if weight is below 80 per cent of the standard weight for height, the individual’s nutrition is probably inadequate as a result of poor diet or disease, and if 20 per cent above the standard, he or she is considered to be suffering from obesity. An alternative method of assessment is use of the body mass index (, or Quetelet’s index), obtained by dividing weight in kilograms by the square of height in metres. A healthy weight is 20–25 ; a of greater than 25 indicates that a person is overweight. weight loss This occurs any time there is a decrease in energy intake compared with energy expenditure. The decrease may be due to deliberate weight reduction or a change in diet or activity level. It may also be a symptom of a disorder. Unexplained weight loss should always be investigated by a doctor.
Many diseases disrupt the appetite, which may lead to weight loss. Depression reduces the motivation to eat, peptic ulcer causes pain and possible food avoidance, and some kidney disorders cause loss of appetite due to the effect of uraemia. In anorexia nervosa and bulimia, complex psychological factors affect an individual’s eating pattern.
Digestive disorders, such as gastroenteritis, lead to weight loss through vomiting. Cancer of the oesophagus (see oesophagus, cancer of) and stomach cancer cause loss of weight, as does malabsorption of nutrients in certain disorders of the intestine or pancreas.
Some disorders cause weight loss by increasing the rate of metabolic activity in cells. Examples are any type of cancer, chronic infection such as tuberculosis, and hyperthyroidism. Untreated diabetes mellitus also causes weight loss due to a number of factors.... weight
The rays are part of the electro-magnetic spectrum; their wavelengths are between 10?9 and 10? 13 metres; in behaviour and energy they are identical to the gamma rays emitted by radioactive isotopes. Diagnostic X-rays are generated in an evacuated tube containing an anode and cathode. Electrons striking the anode cause emission of X-rays of varying energy; the energy is largely dependent on the potential di?erence (kilovoltage) between anode and cathode. The altered tissue penetration at di?erent kilovoltages is used in radiographing di?erent regions, for example in breast radiography (25–40 kV) or chest radiography (120–150 kV). Most diagnostic examinations use kilovoltages between 60 and 120. The energy of X-rays enables them to pass through body tissues unless they make contact with the constituent atoms. Tissue attenuation varies with atomic structure, so that air-containing organs such as the lung o?er little attenuation, while material such as bone, with abundant calcium, will absorb the majority of incident X-rays. This results in an emerging X-ray pattern which corresponds to the structures in the region examined.
Radiography The recording of the resulting images is achieved in several ways, mostly depending on the use of materials which ?uoresce in response to X-rays. CONTRAST X-RAYS Many body organs are not shown by simple X-ray studies. This led to the development of contrast materials which make particular organs or structures wholly or partly opaque to X-rays. Thus, barium-sulphate preparations are largely used for examining the gastrointestinal tract: for example, barium swallow, barium meal, barium follow-through (or enteroclysis) and barium enema. Water-soluble iodine-containing contrast agents that ionise in solution have been developed for a range of other studies.
More recently a series of improved contrast molecules, chie?y non-ionising, has been developed, with fewer side-effects. They can, for example, safely be introduced into the spinal theca for myeloradiculography – contrast X-rays of the spinal cord. Using these agents, it is possible to show many organs and structures mostly by direct introduction, for example via a catheter (see CATHETERS). In urography, however, contrast medium injected intravenously is excreted by the kidneys which are outlined, together with ureters and bladder. A number of other more specialised contrast agents exist: for example, for cholecystography – radiological assessment of the gall-bladder. The use of contrast and the attendant techniques has greatly widened the range of radiology. IMAGE INTENSIFICATION The relative insensitivity of ?uorescent materials when used for observation of moving organs – for example, the oesophagus – has been overcome by the use of image intensi?cation. A faint ?uorographic image produced by X-rays leads to electron emission from a photo-cathode. By applying a high potential di?erence, the electrons are accelerated across an evacuated tube and are focused on to a small ?uorescent screen, giving a bright image. This is viewed by a TV camera and the image shown on a monitor and sometimes recorded on videotape or cine. TOMOGRAPHY X-ray images are two-dimensional representations of three-dimensional objects. Tomography (Greek tomos
– a slice) began with X-ray imaging produced by the linked movement of the X-ray tube and the cassette pivoting about a selected plane in the body: over- and underlying structures are blurred out, giving a more detailed image of a particular plane.
In 1975 Godfrey Houns?eld introduced COMPUTED TOMOGRAPHY (CT). This involves
(i) movement of an X-ray tube around the patient, with a narrow fan beam of X-rays; (ii) the corresponding use of sensitive detectors on the opposite side of the patient; (iii) computer analysis of the detector readings at each point on the rotation, with calculation of relative tissue attenuation at each point in the cross-sectional plant. This invention has enormously increased the ability to discriminate tissue composition, even without the use of contrast.
The tomographic e?ect – imaging of a particular plane – is achieved in many of the newer forms of imaging: ULTRASOUND, magnetic resonance imaging (see MRI) and some forms of nuclear medicine, in particular positron emission tomography (PET SCANNING). An alternative term for the production of images of a given plane is cross-sectional imaging.
While the production of X-ray and other images has been largely the responsibility of radiographers, the interpretation has been principally carried out by specialist doctors called radiologists. In addition they, and interested clinicians, have developed a number of procedures, such as arteriography (see ANGIOGRAPHY), which involve manipulative access for imaging – for example, selective coronary or renal arteriography.
The use of X-rays, ultrasound or computerised tomography to control the direction and position of needles has made possible guided biopsies (see BIOPSY) – for example, of pancreatic, pulmonary or bony lesions – and therapeutic procedures such as drainage of obstructed kidneys (percutaneous nephrostomy), or of abscesses. From these has grown a whole series of therapeutic procedures such as ANGIOPLASTY, STENT insertion and renal-stone track formation. This ?eld of interventional radiology has close a?nities with MINIMALLY INVASIVE SURGERY (MIS).
Radiotherapy, or treatment by X-rays The two chief sources of the ionising radiations used in radiotherapy are the gamma rays of RADIUM and the penetrating X-rays generated by apparatus working at various voltages. For super?cial lesions, energies of around 40 kilovolts are used; but for deep-seated conditions, such as cancer of the internal organs, much higher voltages are required. X-ray machines are now in use which work at two million volts. Even higher voltages are now available through the development of the linear accelerator, which makes use of the frequency magnetron which is the basis of radar. The linear accelerator receives its name from the fact that it accelerates a beam of electrons down a straight tube, 3 metres in length, and in this process a voltage of eight million is attained. The use of these very high voltages has led to the development of a highly specialised technique which has been devised for the treatment of cancer and like diseases.
Protective measures are routinely taken to ensure that the patient’s normal tissue is not damaged during radiotherapy. The operators too have to take special precautions, including limits on the time they can work with the equipment in any one period of time.
The greatest value of radiotherapy is in the treatment of malignant disease. In many patients it can be used for the treatment of malignant growths which are not accessible to surgery, whilst in others it is used in conjunction with surgery and chemotherapy.... x-rays
FAMILY: Myrtaceae
SYNONYMS: P. officinalis, pimento, pimenta, Jamaica pepper.
GENERAL DESCRIPTION: An evergreen tree which reaches about 10 metres high and begins to produce fruit in its third year. Each fruit contains two kidney-shaped green seeds which turn glossy black upon ripening.
DISTRIBUTION: Indigenous to the West Indies and South America, it is cultivated extensively in Jamaica, Cuba and, to a lesser degree, in Central America. Imported berries are distilled in Europe and America.
OTHER SPECIES: Four other varieties of pimento are found in Venezuela, Guyana and the West Indies which are used locally as spices.
HERBAL/FOLK TRADITION: Used for flatulent indigestion and externally for neuralgic or rheumatic pain. Pimento water is used as a vehicle for medicines which ease dyspepsia and constipation since it helps prevent griping pains. It is used extensively as a domestic spice – allspice is so called because it tastes like a combination of cloves, juniper berries, cinnamon and pepper.
ACTIONS: Anaesthetic, analgesic, anti-oxidant, antiseptic, carminative, muscle relaxant, rubefacient, stimulant, tonic.
EXTRACTION: Essential oil by steam distillation from 1. the leaves, and 2. the fruit. The green unripe berries contain more oil than the ripe berries, but the largest percentage of oil is contained in the shell of the fruit. An oleoresin from the berries is also produced in small quantities.
CHARACTERISTICS: 1. Pimenta leaf oil is a yellowish-red or brownish liquid with a powerful sweet-spicy scent, similar to cloves. 2. Pimenta berry oil is a pale yellow liquid with a sweet warm balsamic-spicy bodynote (middle note) and fresh, clean top note. It blends well with ginger, geranium, lavender, opopanax, labdanum, ylang ylang, patchouli, neroli, oriental and spicy bases.
PRINCIPAL CONSTITUENTS: Mainly eugenol, less in the fruit (60–80 per cent) than in the leaves (up to 96 per cent), also methyl eugenol, cineol, phellandrene and cryophyllene among others.
SAFETY DATA: Eugenol irritates the mucous membranes, and has been found to cause dermal irritation. Pimenta leaf and berry oil should therefore be used with care in low dilutions only.
AROMATHERAPY/HOME: USE:
Circulation, muscles and joints: Arthritis, fatigue, muscle cramp, rheumatism, stiffness etc. ‘Used in tiny amounts … in a massage oil for chest infections, for severe muscle spasm to restore mobility quickly, or where extreme cold is experienced.’1
Respiratory System: Chills, congested coughs, bronchitis.
Digestive System: Cramp, flatulence, indigestion, nausea.
Nervous System: Depression, nervous exhaustion, neuralgia, tension and stress.
OTHER USES: Used in aromatic carminative medicines; as a fragrance component in cosmetics and perfumes, especially soaps, aftershaves, spicy and oriental fragrances. Both leaf and berry oil are used extensively for flavouring foods, especially savoury and frozen foods, as well as alcoholic and soft drinks.... allspice
FAMILY: Rosaceae
SYNONYMS: P. amygdalus var. amara, Amygdalus communis var. amara, A. dulcis, P. communis.
GENERAL DESCRIPTION: The almond tree grows to a height of about 7 metres and is popular as a garden tree due to its pinky-white blossom. It is botanically classified as a drupe.
DISTRIBUTION: Native to Western Asia and North Africa, it is now extensively cultivated throughout the Mediterranean region, Israel and California.
OTHER SPECIES: There are two main types of almond tree – bitter and sweet. The sweet almond does not produce any essential oil.
HERBAL/FOLK TRADITION: A ‘fixed’ oil commonly known as ‘sweet almond oil’ is made by pressing the kernels from both the sweet and bitter almond trees. Unlike the essential oil, this fixed oil does not contain any benzaldehyde or prussic acid, and has many medical and cosmetic uses. It is used as a laxative, for bronchitis, coughs, heartburn and for disorders of the kidneys, bladder and biliary ducts. It helps relieve muscular aches and pains, softens the skin and premotes a clear complexion.
ACTIONS: Anaesthetic, antispasmodic, narcotic, vermifuge (FFPA).
EXTRACTION: Essential oil by steam distillation from the kernels. The nuts are first pressed and macerated in warm water for 12 to 24 hours before the oil is extracted. It is during this process that the prussic acid is formed; it is not present in the raw seed. Most commercial bitter almond oil is rectified to remove all prussic acid, i.e. free from prussic acid (FFPA).
CHARACTERISTICS: Light colourless liquid with a characteristic ‘marzipan’ scent (FFPA).
PRINCIPAL CONSTITUENTS: Benzaldehyde (95 per cent), prussic acid (3 per cent).
SAFETY DATA: Prussic acid, also known as hydrocyanic acid or cyanide, is a well-known poison. Benzaldehyde is also moderately toxic.
AROMATHERAPY/HOME: USE None. ‘Should not be used in therapy either internally or externally.’2
OTHER USES: Bitter almond oil is no longer used for internal medication. Rectified bitter almond oil is used for flavouring foods, mainly confectionery; the most common uses are ‘almond essence’ and marzipan. The oil (FFPA) is increasingly being replaced by synthetic benzaldehyde in food flavourings.... almond, bitter
FAMILY: Malvaceae
SYNONYMS: Hibiscus abelmoschus, musk seed, Egyptian alcee, target-leaved hibiscus, muskmallow.
GENERAL DESCRIPTION: An evergreen shrub about 1.5 metres high, bearing large single yellow flowers with a purple centre. The capsules, in the form of five-cornered pyramids, contain the greyish-brown kidney-shaped seeds which have a musky odour.
DISTRIBUTION: Indigenous to India; widely cultivated in tropical countries including Indonesia, Africa, Egypt, China, Madagascar, and the West Indies. Distillation of the oil is generally carried out in Europe and America.
OTHER SPECIES: A variety, H. esculentus, is grown largely in Istanbul as a demulcent. Another variety is also found in Martinique, the seeds of which have a more delicate scent.
HERBAL/FOLK TRADITION: Generally used as a stimulant and to ease indigestion, cramp and nervous dyspepsia. In Chinese medicine it is used to treat headache; in Egypt the seeds are used to sweeten the breath and are made into an emulsion with milk to be used for itch. The Arabs use the seeds to mix with coffee. Widely used as a domestic spice in the East.
ACTIONS: Antispasmodic, aphrodisiac, carminative, nervine, stimulant, stomachic.
EXTRACTION: Essential oil by steam distillation of the seeds. Liquid ambrette seed oil should be allowed to age for several months before it is used. A concrete and absolute are also produced by solvent extraction.
CHARACTERISTICS: A pale yellowy-red liquid with a rich, sweet floral-musky odour, very tenacious. It blends well with rose, neroli, sandalwood, clary sage, cypress, patchouli, oriental and ‘sophisticated’ bases.
PRINCIPAL CONSTITUENTS: Ambrettolide, ambrettolic acid, palmitic acid and farnesol.
SAFETY DATA: Available information indicates the oil to be non-toxic, non-irritant and non-sensitizing.
AROMATHERAPY/HOME: USE
Circulation muscles and joints: Cramp, fatigue, muscular aches and pains, poor circulation.
Nervous System: Anxiety, depression, nervous tension and stress-related conditions.
OTHER USES: Employed by the cosmetic and perfumery industries in oriental-type scents and for the adulteration of musk; also used as a musk substitute. Used for flavouring alcoholic and soft drinks as well as some foodstuffs, especially confectionery.
AMYRIS... ambrette seed
FAMILY: Illiciaceae
SYNONYMS: Chinese anise, illicium, Chinese star anise.
GENERAL DESCRIPTION: Evergreen tree up to 12 metres high with a tall, slender white trunk. It bears fruit which consist of five to thirteen seed-bearing follicles attached to a central axis in the shape of a star.
DISTRIBUTION: Native to south east China, also Vietnam, India and Japan. Mainly produced in China.
OTHER SPECIES: Several other related species, e.g. Japanese star anise which is highly poisonous!
HERBAL/FOLK TRADITION: Used in Chinese medicine for over 1300 years for its stimulating effect on the digestive system and for respiratory disorders such as bronchitis and unproductive coughs.

GENERAL DESCRIPTION: A large branching perennial herb up to 3 metres high, with a thick fleshy root system and pale yellow-green flowers.
DISTRIBUTION: Native to Afghanistan, Iran and other regions of south west Asia.
OTHER SPECIES: There are several other species of Ferula which yield the oleoresin known as ‘asafetida’, e.g. Tibetan asafetida, which is also used to a lesser extent in commerce.
HERBAL/FOLK TRADITION: In Chinese medicine it has been used since the seventh century as a nerve stimulant in treating neurasthenia. It is also widely used in traditional Indian medicine, where it is believed to stimulate the brain. In general, it has the reputation for treating various ailments including asthma, bronchitis, convulsions, coughs, constipation, flatulence and hysteria. The foliage of the plant is used as a local vegetable. It is current in the British Herbal Pharmacopoeia as a specific for intestinal flatulent colic.
ACTIONS: Antispasmodic, carminative, expectorant, hypotensive, stimulant. Animals are repelled by its odour.
EXTRACTION: The oleoresin is obtained by making incisions into the root and above ground parts of the plant. The milky juice is left to leak out and harden into dark reddish lumps, before being scraped off and collected. The essential oil is then obtained from the resin by steam distillation. An absolute, resinoid and tincture are also produced.
CHARACTERISTICS: A yellowy-orange oil with a bitter acrid taste and a strong, tenacious odour resembling garlic. However, beneath this odour there is a sweet, balsamic note.
PRINCIPAL CONSTITUENTS: Disulphides, notably 2-butyl propenyl disulphide with monoterpenes, free ferulic acid, valeric, traces of vanillin, among others.
SAFETY DATA: Available information indicates the oil to be relatively non-toxic and non-irritant. However, it has the reputation for being the most adulterated ‘drug’ on the market. Before being sold, the oleoresin is often mixed with red clay or similar substitutes.

GENERAL DESCRIPTION: A tall, graceful evergreen tree up to 20 metres high, with a tapering trunk and numerous branches giving the tree an overall shape of a perfect cone. It forms blisters of oleoresin (the so-called ‘balsam’) on the trunk and branches, produced from special vesicles beneath the bark. The tree does not produce a ‘true’ balsam, since it does not contain benzoic or cinnamic acid in its esters; it is really an oleoresin, being a mixture of resin and essential oil.
DISTRIBUTION: Native to North America, particularly Quebec, Nova Scotia and Maine.
OTHER SPECIES: The hemlock spruce (Tsuga canadensis) also yields an exudation sold under the name of ‘Canada balsam’. There are also many other species of fir which produce oils from their needles – see entry on silver fir and Botanical Classification section. NB: Not to be confused with the genuine balsam of Gilead (Commiphora opabalsamum), of ancient repute.

DISTRIBUTION: Native to southern Canada and southeastern USA; produced mainly in Pennsylvania.
OTHER SPECIES: There are numerous species of birch, spanning several continents, such as black birch (B. nigra) found in North America. Not to be confused with the European white birch (B. alba), which produces birch tar oil used in chronic skin diseases.
HERBAL/FOLK TRADITION: The cambium (the layer directly under the bark) is eaten in the spring, cut into strips like vermicelli. The bark, in the form of an infusion, is used as a general stimulant and to promote sweating. As a decoction or syrup, it is used as a tonic for dysentery and is said to be useful in genito-urinary irritation. The flavour of wintergreen and birch bark, in the form of a tea, was popular with the American Indians and European settlers. More recently, this has been translated into a preference for ‘root beer’ flavourings.
ACTIONS: Analgesic, anti-inflammatory, antipyretic, antirheumatic, antiseptic, astringent, depurative, diuretic, rubefacient, tonic.
EXTRACTION: Essential oil by steam distillation of the bark macerated in warm water.

FAMILY: Styracaceae
SYNONYMS: Gum benzoin, gum benjamin, styrax benzoin.
GENERAL DESCRIPTION: A large tropical tree up to 20 metres high with pale green citrus-like leaves, whitish underneath, bearing hard-shelled flattish fruit about the size of a nutmeg. The benzoin is a pathological product, formed when the trunk is cut; the tree exudes a balsamic resin which hardens upon exposure, to air and sunlight.
DISTRIBUTION: Native to tropical Asia; the two main regions of production are Sumatra, Java and Malaysia for ‘Sumatra’ benzoin, and Laos, Vietnam, Cambodia, China and Thailand for ‘Siam’ benzoin.
OTHER SPECIES: There are many different varieties within the Styrax family which produce benzoin, but these are generally classified under either Sumatra benzoin (S. paralleloneurus) or Siam benzoin (S. tonkinensis) – see also Botanical Classification section.
HERBAL/FOLK TRADITION: It has been used for thousands of years in the east as a medicine and incense; the fumigations were believed to drive away evil spirits. It was used by the Chinese herbalists for its heating and drying qualities, as a good urinary antiseptic and as an aid to digestion.
In the west, it is best known in the form of compound tincture of benzoin or Friars Balsam, used for respiratory complaints. Externally it is used for cuts and irritable skin conditions; internally it is used as a carminative for indigestion, etc. It also acts as a preservative of fats.
ACTIONS: Anti-inflammatory, anti-oxidant, antiseptic, astringent, carminative, cordial, deodorant, diuretic, expectorant, sedative, styptic, vulnerary.
EXTRACTION: The crude benzoin is collected from the trees directly. Benzoin resinoid, or ‘resin absolute’, is prepared from the crude using solvents, for example benzene and alcohol, which are then removed. Commercial benzoin is usually sold dissolved in ethyl glycol or a similar solvent. A ‘true’ absolute is also produced in small quantities.
CHARACTERISTICS: 1. Sumatra crude benzoin occurs as greyish-brown brittle lumps with reddish streaks, with a styrax-like odour. There are several different qualities available; the so-called ‘almond’ grade is considered superior. 2. Siam benzoin comes in pebble or tear-shaped orange-brown pieces, with a sweet-balsamic vanilla-like scent, this type having a more refined odour than the Sumatra type.
Benzoin resinoid is produced from both the Siam and Sumatra types, or a mix of the two. It is an orange-brown viscous mass with an intensely rich sweet-balsamic odour. It blends well with sandalwood, rose, jasmine, copaiba balsam, frankincense, myrrh, cypress, juniper, lemon, coriander and other spice oils.
PRINCIPAL CONSTITUENTS: 1. Sumatra Benzoin: mainly coniferyl cinnamate and sumaresinolic acid, with benzoic acid, cinnamic acid, and traces of styrene, vanillin and benzaldehyde. 2. Siam benzoin: mainly coniferyl benzoate (65–75 per cent), with benzoic acid, vanillin, siaresinolic acid and cinnamyl benzoate.
SAFETY DATA: Non-toxic, non-irritant, possible sensitization. Compound benzoin tincture is ‘regarded as moderately toxic, due probably to occasional contact dermatitis developed in some individuals … which contains, in addition to benzoin, aloe, storax, Tolu balsam and others.’.
AROMATHERAPY/HOME: USE
Skin Care: Cuts, chapped skin, inflamed and irritated conditions.
Circulation, Muscles And Joints: Arthritis, gout, poor circulation, rheumatism.
Respiratory System: Asthma, bronchitis, chills, colic, coughs, laryngitis.

HERBAL/FOLK TRADITION: Birch buds were formerly used as a tonic in hair preparations. Birch tar is used in Europe for all types of chronic skin complaints: psoriasis, eczema, etc. In Scandinavia the young birch leaflets and twigs are bound into bundles and used in the sauna to tone the skin and promote the circulation. The sap is also tapped in the spring and drunk as a tonic. Buds, leaves and bark are used for ‘rheumatic and arthritic conditions, especially where kidney functions appear to need support … oedematous states; urinary infections and calculi.’.
ACTIONS: Anti-inflammatory, antiseptic, cholagogue, diaphoretic, diuretic, febrifuge, tonic.
EXTRACTION: 1. Essential oil by steam distillation from the leaf-buds. 2. Crude birch tar is extracted by slow destructive distillation from the bark; this is subsequently steam distilled to yield a rectified birch tar oil.

DISTRIBUTION: Native to Borneo and Sumatra.
OTHER SPECIES: To be distinguished from the Japanese or Formosa type of camphor, more commonly used in Europe, which is relatively toxic. See also Botanical Classification section.
HERBAL/FOLK TRADITION: Borneol has long been regarded as a panacea by many Eastern civilizations, especially in ancient Persia, India and China. It was used as a powerful remedy against plague and other infectious diseases, stomach and bowel complaints. In China it was also used for embalming purposes. ‘It is mentioned by Marco Polo in the thirteenth century and Camoens in 1571 who called it the “balsam of disease”.’. It is valued for ceremonial purposes in the east generally, and in China particularly for funeral rites. Its odour repels insects and ants, and it is therefore highly regarded as timber for the construction of buildings.
ACTIONS: Mildly analgesic, antidepressant, antiseptic, antispasmodic, antiviral, carminative, rubefacient, stimulant of the adrenal cortex, tonic (cardiac and general).
EXTRACTION: The borneol is collected from the tree trunk in its crude crystalline form (the natives test each tree first by making incisions in the trunk to detect its presence). The so-called ‘oil of borneol’ is extracted by steam distillation of the wood.
CHARACTERISTICS: Watery white to viscous black oil depending upon the amount of camphor which it contains, with a distinctive, sassafras-like, camphoraceous odour.

The branches were also used for thatching, basketwork, fencing and, of course, for making brooms. Spanish broom has similar therapeutic properties to the common broom, which is still current in the British Herbal Pharmacopoeia for cardiac dropsy, myocardial weakness, tachycardia and profuse menstruation. However, the Spanish broom is said to be five to six times more active than the common broom, and even that must be used with caution by professional herbalists due to the strength of the active ingredients: ‘A number of cases of poisoning have occurred from the substitution of the dried flowers of Spartium for those of true Broom.’.
ACTIONS: Antihaemorrhagic, cardioactive, diuretic, cathartic, emmenagogue, narcotic, vasoconstrictor.
EXTRACTION: An absolute is obtained by solvent extraction from the dried flowers.
CHARACTERISTICS: A dark brown, viscous liquid with an intensely sweet, floral, hay-like scent with a herbaceous undertone. It blends well with rose, tuberose, cassie, mimosa, violet, vetiver and herbaceous-type fragrances.
PRINCIPAL CONSTITUENTS: The absolute contains capryllic acid, phenols, aliphatics, terpenes, esters, scoparin and sparteine, as well as wax, etc.
SAFETY DATA: Sparteine, which is contained in the flowers as the main active constituent, is toxic. In large doses, it causes vomiting, renal irritation, weakens the heart, depresses the nerve cells and lowers the blood pressure, and in extreme cases causes death.
AROMATHERAPY/HOME: USE None.
OTHER USES: Used in soaps, cosmetics and high-class perfumery; also as a flavour ingredient in sweet rich ‘preserves’, alcoholic and soft drinks.... broom, spanish

FAMILY: Magnoliaceae
SYNONYMS: M. aurantiaca, Magnolia champaca, joy perfume tree, champak, champac, champa, golden champaca.
GENERAL DESCRIPTION: Champaca is a large, sub-tropical tree up to 6 metres high with a smooth grey bark and long, oval-shaped, glossy evergreen leaves. The flowers have 10–20 yellow, orange or cream-coloured narrow petals and an extremely heady fragrance. They bloom both in spring and autumn – on a warm, humid night, the scent can be enjoyed several hundred feet away! Champaca fruit are brown, containing bright red seeds.
DISTRIBUTION: Michelia champaca is native to India, where it occurs in humid, tropical evergreen forests. It is also found throughout Indo-China, Malaysia, Sumatra, Java and south-western China, as well as occurring naturally in the eastern Himalayan region. It is often grown as a boulevard tree in the tropics and in India is frequently planted in Hindu temple grounds and ornamental gardens. Champaca, especially its white-flowered hybrid, is now commonly cultivated in warm climates worldwide, for example, in California.
OTHER SPECIES: The genus Michelia contains about 40 species with a distribution including India, Malaysia, Indonesia, southern Japan, Taiwan and China. The leaves and flowers of the Michelia species resemble Magnolia, but the blossoms of Michelia generally form clusters among the leaves, rather than singly at the branch ends like Magnolia. There are several related species of M. champaca, such as the red champaca and the white champaca, grown specifically for their scented flowers, which are also used to produce essential oils. M. x alba, a white-flowered hybrid of M. champaca and M. montana, is prized throughout Asia for its fragrant, pure-white flowers, which are commonly floated in water bowls as Buddhist temple offerings and used a household decoration.
NB: Occasionally champaca is confused with champaca wood oil or guaiacwood oil (Bulnesia sarmienti), also known as palo santo (meaning ‘holy wood’), which is derived from an entirely different species native to South America.
HERBAL/FOLK TRADITION: Champaca is regarded as one of the most sacred trees of India and tropical Asia and has been revered by the people of India for thousands of years. M. champaca is sacred to Hindus and Buddhists alike and the flower is especially sacred to the Hindi god Vishnu, the god of love, and his consort Lakshmi. In India, the flowers are also used for adornment and their alluring scent is employed as a natural aphrodisiac, and as a fragrant decoration for bridal beds and for garlands.
All parts of the tree are considered medicinal and are utilized in various traditional remedies. In India, the scented oil infused from the champaca blossom is used for relief of vertigo and headaches. As a herbal remedy, the flowers have been used to treat urinary tract infections and as an emollient, febrifuge and to soothe anxiety. It is also considered a valuable aid for the treatment of all skin types, particularly mature, dry or sensitive skin. The derivation of the word ‘shampoo’ is the Hindi word champo, meaning ‘to massage’, which comes from champa, the Sanskrit name for champaca. This is because the oil from the tree was traditionally used to make fragrant hair and massage oils!
ACTIONS: Antidepressant, aphrodisiac, antispasmodic, antiseptic, antiviral, astringent, emollient, euphoric, emollient, febrifuge, stimulant and tonic.
EXTRACTION: The absolute is produced by solvent extraction from the fresh flowers. (An oil is also produced by steam distillation of the petals). The absolute requires thousands of fresh flowers to produce a tiny amount: thus its high cost.
CHARACTERISTICS: An intense, fresh, green-floral scent with an underlying warmth and subtle leafy notes. It blends well with jasmine, lemon, coriander, tuberose, grapefruit, bergamot, rose, ylang ylang, neroli, sandalwood and other floral scents
PRINCIPAL CONSTITUENTS: Champaca absolute contains mainly linalool, benzyl acetate, beeta lonone, phenyl ethyl alcohol, gamma-selinene, benzyl benzoate, phenylethyl benzoate and eugenol.

GENERAL DESCRIPTION: An erect, annual herb up to 3 metres high, belonging to the mint family, with a hollow stem, and bearing purple-blue lipped flowers and dark brown, shield-shaped fruits. The oval leaves, which are wrinkled along the edge and pointed, have a strong mint-like aroma when crushed; the taproot is white or brown. It is a very well known pseudo-cereal plant in the Latin America region.
DISTRIBUTION: A native of tropical America, growing in warm and semi-warm regions, commonly found in the rain forests of Ecuador, as well as in the Caribbean and Hawaii; it has also been naturalized in Australia since the mid-nineteenth century. This herb is commonly found alongside roadsides and watercourses and is considered a weed in many tropical areas around the world, especially because the plant can be invasive.
OTHER SPECIES: The mint family is generally known to produce the most variation in essential oil composition and therefore there are many chemotypes of H. suaveolens. Ocotea essential oil from the flowers of the Ocotea quixos tree, which is native to the deep Amazon, is another species found in South America, which yields a little-known essential oil sharing many of phytochemical properties and functions of H. suaveolens.
HERBAL/FOLK TRADITION: Dorado Azul has been used by many indigenous cultures in India, Nigeria and elsewhere for hundreds of years to treat bacterial infections, diarrhoea, tumours, skin diseases, gastro-intestinal disorders and as a natural mosquito repellent and pesticide. The herb has also traditionally been used for the treatment of asthma, hormonal balance (oestrogen), inflammation, muscular aches and pains and for wound healing.
Today the essential oil of Dorado Azul is recognized largely for its role in treating respiratory conditions and in supporting the sinuses and lungs, much like mint and eucalyptus. In addition to its respiratory benefits, Dorado Azul oil is also proving to be a very effective ingredient in essential oil blends that repel insects and pests. Indeed, recent studies have confirmed it is effective as a natural crop and grain insecticide. A study in 1999 revealed that the oil was effective against both gram positive (Bacillus cereus and Staphylococcus aureus) and negative (E. coli, Pseudomonas spp.) bacterial strains; as well as Candida albicans. A further study exhibited broad-spectrum antibacterial and antifungal activity against Aspergillus niger and Micrococcus luteus respectively.
ACTIONS: Analgesic, anti-inflammatory, antifungal, antimicrobial, antioxidant, anticancer, insecticidal, anti-infectious, expectorant, immune stimulant.

PRINCIPAL CONSTITUENTS: Mainly sesquiterpene lactones, including alantolactone (or helenin), isolactone, dihydroisalantolactone, dihydralantolactone, alantic acid and azulene.
SAFETY DATA: Non-toxic, non-irritant; however it is a severe dermal sensitizer. In clinical tests it caused ‘extremely severe allergic reactions’ in twenty-three out of twenty-five volunteers. On the basis of these results it is recommended that the oil ‘should not be used on the skin at all’..
AROMATHERAPY/HOME: USE None.
NB In Phytoguide I, sweet inula (I. odora or I. graveolens), a deep green oil, is described as ‘queen of mucolytic essential oils’, having properties as diverse as: ‘anti-inflammatory, hyperthermic, sedative, cardia-regulative, diuretic and depurative’.. It is described as being an excellent oil for the cardiopulmonary zone including asthma, chronic bronchitis and unproductive coughs. This variety of Inula seems to avoid the sensitization problems of elecampane, at least when it is used as an inhalation or by aerosol treatment.
OTHER USES: Alantolactone is used as an anthelmintic in Europe (it is also an excellent bactericide). The oil and absolute are used as fixatives and fragrance components in soaps, detergents, cosmetics and perfumes. Used as a flavour ingredient in alcoholic beverages, soft drinks and foodstuffs, especially desserts.... elecampane

OTHER SPECIES: There are over 700 different species of eucalyptus, of which at least 500 produce a type of essential oil. Many have been extracted simply for experimental purposes, and research is still being carried out with regard to the different constituents of each oil. In general, they can be divided into three categories. 1. The medicinal oils containing large amounts of cineol (or eucalyptol), such as the blue gum, but increasingly the blue malee (E. polybractea), the narrow-leaved peppermint (E. radiata var. australiana) and the gully gum (E. smithii). 2. The industrial oils containing mainly piperitone and phellandrene, such as the peppermint eucalyptus (E. piperita), grey peppermint (E. radiata var. phellandra) and increasingly the broad-leaved peppermint (E. dives var. Type). 3. The perfumery oils containing mainly citronellal, such as the lemon-scented eucalyptus (E. citriodora). See also Botanical Classification section.
HERBAL/FOLK TRADITION: A traditional household remedy in Australia, the leaves and oil are especially used for respiratory ailments such as bronchitis and croup, and the dried leaves are smoked like tobacco for asthma. It is also used for feverish conditions (malaria, typhoid, cholera, etc.) and skin problems like burns, ulcers and wounds. Aqueous extracts are used for aching joints, bacterial dysentery, ringworms, tuberculosis, etc. and employed for similar reasons in western and eastern medicine.

SAFETY DATA: Generally non-toxic and non-irritant, although it has been known to irritate the stomach; may also cause sensitization in some individuals.
AROMATHERAPY/HOME: USE Due to its unpleasant and pervasive smell, the oil is not often used externally. However, the capsules may be taken internally according to the instructions on the label for respiratory and gastro-intestinal infections, urinary tract infections such as cystitis, heart and circulatory problems, and to fight infectious diseases in general.
OTHER USES: The oil is made into capsules and also included in many health food products mainly to help reduce high blood pressure and protect against heart disease. Extensively employed as a flavour ingredient in most major food categories, especially savouries.... garlic
FAMILY: Apiaceae (Umbelliferae)
SYNONYMS: F. officinale, F. capillaceum, Anethum foeniculum, fenkel.
GENERAL DESCRIPTION: Biennial or perennial herb up to 2 metres high, with feathery leaves and golden yellow flowers. There are two main varieties of fennel: bitter or common Fennel, slightly taller with less divided leaves occurring in a cultivated or wild form and sweet fennel (also known as Roman, garden or French fennel) which is always cultivated.
DISTRIBUTION: Bitter fennel is native to the Mediterranean region, found growing wild in France, Spain, Portugal and North Africa (they produce the ‘weed’oil). It is cultivated extensively worldwide, the main oil producers being Hungary, Bulgaria, Germany, France, Italy and India.
Sweet fennel is thought to have originated on the island of Malta, having been introduced by monks or crusaders thousands of years ago. It is now grown principally in France, Italy and Greece.
OTHER SPECIES: Bitter fennel (F. vulgare var. amara) and sweet fennel (F. vulgare var. dulce) are both closely related to the Florence fennel (F. azoricum), a smaller plant with a large cylindrical fleshy root which can be eaten as a vegetable. There are also many other cultivated varieties such as the German or Saxon fennel, the Russian, Indian and Japanese fennel, all of which produce slightly different oils.
HERBAL/FOLK TRADITION: A herb of ancient medical repute, believed to convey longevity, courage and strength. It was also used to ward off evil spirits, strengthen the eyesight and to neutralize poisons. In eastern and western herbalism it is considered good for obstructions of the liver, spleen and gall bladder and for digestive complaints such as colic, indigestion, nausea and flatulence (an ingredient of children’s ‘gripe water’).
It has traditionally been used for obesity, which may be due to a type of oestrogenic action, which also increases the milk of nursing mothers. Still current in the British Herbal Pharmacopoeia, used locally for conjunctivitis, blepharitis and pharyngitis.
ACTIONS: Aperitif, anti-inflammatory, antimicrobial, antiseptic, antispasmodic, carminative, depurative, diuretic, emmenagogue, expectorant, galactagogue, laxative, orexigenic, stimulant (circulatory), splenic, stomachic, tonic, vermifuge.
EXTRACTION: Essential oil by steam distillation. 1. Sweet fennel oil is obtained from crushed seeds, and 2. bitter fennel oil from crushed seeds or the whole herb (the wild ‘weed’).
CHARACTERISTICS: 1. A colourless to pale yellow liquid with a very sweet, anise-like, slightly earthy-peppery scent. It blends well with geranium, lavender, rose and sandalwood. 2. The seed oil is a pale yellow liquid with a sharp, warm camphoraceous odour; the ‘weed’ oil is pale orange-brown with a sharp, peppery-camphoraceous odour.
PRINCIPAL CONSTITUENTS: Anethole (50–60 per cent), limonene, phellandrene, pinene, anisic acid, anisic aldehyde, camphene, limonene, among others. In addition, bitter fennel oil contains 18–22 per cent fenchone, whereas the sweet fennel oil contains little or none.
SAFETY DATA: Non-irritant, relatively non-toxic, narcotic in large doses; bitter fennel may cause sensitization in some individuals. Sweet fennel oil is preferred in aromatherapy and perfumery work, since it does not contain the harsh ‘fenchone’ note, and because it is non-sensitizing. Bitter fennel oil should not be used on the skin at all, although it is considered superior medicinally. Neither oil should be used by epileptics or during pregnancy. Use in moderation.
AROMATHERAPY/HOME: USE Bitter fennel – none.
Sweet fennel:
Skin Care: Bruises, dull, oily, mature complexions, pyorrhoea.
Circulation Muscles And Joints: Cellulitis, obesity, oedema, rheumatism.
Respiratory System: Asthma, bronchitis.

FAMILY: Fabaceae
SYNONYMS: Greek hay, methi, alholva, bird’s foot, chandrika, fenigreek, Greek clover.
GENERAL DESCRIPTION: An annual plant reaching a height of slightly more than half a metre with trifoliate, bright green leaves. It blossoms during the summer season and produces beautiful small white flowers. The leaves’ fragrance slightly resembles lovage and the brownish-yellow seeds are a distinctive cuboid shape.
DISTRIBUTION: An aromatic herb native to southern Europe and Asia and one of the oldest cultivated medicinal plants. It is widely grown today in the Mediterranean countries, Argentina, India, North Africa and the United States. Major commercial fenugreek-producing countries are Afghanistan, Pakistan, Iran, Nepal, Bangladesh, Argentina, Egypt, France, Spain, Turkey and Morocco, although the largest producer is India. When harvested as micro-greens, fenugreek is known as ‘samudra methi’ in Mumbai.
OTHER SPECIES: The cultivated fenugreek is thought to have derived from a wild species, native to India.
HERBAL/FOLK TRADITION: Fenugreek is an ancient spice, although currently not much used in the West. While the seeds and leaves have primarily been used as a culinary spice, it was also employed in classical times as livestock feed, hence its common name, ‘Greek hay’. It was used by the ancient Egyptians to combat fever and in the embalming process. It has a long history of use as a medicinal plant in India and throughout Europe: it is still used in Ayurvedic medicine, where it is known as ‘methi’. Fenugreek seeds have been found to contain diosgenin, which is a compound that has properties similar to oestrogen. For this reason, fenugreek has a long history of use as a breast enlarger and to promote the growth of new breast cells. Due to its oestrogen-like properties, fenugreek has been found to help increase sexual libido and lessen the effect of the hot flushes and mood fluctuations that are common symptoms of the menopause and PMS. The plant can also be employed to promote lactation, induce labour and as an aphrodisiac.
In Indian and Chinese medicine, it is traditionally used to treat arthritis, asthma, bronchitis, improve digestion, maintain a healthy metabolism, increase male potency, cure skin problems (wounds, rashes and boils), sore throat and heartburn. Recent studies have shown that fenugreek helps lower blood glucose and cholesterol levels, and may be an effective treatment for both type 1 and 2 diabetes; it is also being studied for its cardiovascular benefits. Topically, the gelatinous texture of fenugreek seed is used for soothing eczema or other skin complaints; it is also applied as a warm poultice to relieve muscle aches and gout. Fenugreek is also nutritious as it is a valuable source of vitamins and minerals, particularly vitamins A, C and D as well as iron and calcium. Fenugreek seeds are rich in protein and carbohydrates and the pressed oil is strangely similar in chemical composition to cod liver oil. It also contains choline and lecithin, both substances needed by the liver for cholesterol metabolism. Fenugreek cleanses, stimulates and helps remove waste products from the body: it stimulates the lymphatic system and aids the kidneys and liver in detoxifying the entire system. The oil contains powerful antioxidants that help slow the ageing process.
ACTIONS: Antioxidant, anti-inflammatory, antiviral, aphrodisiac, bactericidal, carminative, demulcent, expectorant, laxative, nervine, stomachic.
EXTRACTION: Essential oil by steam distillation from the seeds. A fixed oil is also pressed from the seeds.
CHARACTERISTICS: Pale yellow to light brown liquid with a bitter, spicy scent. It blends well with sandalwood, clove, cinnamon, cardamon and other spice oils.
PRINCIPAL CONSTITUENTS: The essential oil is rich in phytic acid, saponins and trigonelline.
SAFETY DATA: The oil may cause skin irritation: dilute well before use. Avoid use during pregnancy, since it has the potential to induce labour.
AROMATHERAPY/HOME: USE
Skin Care: Boils, burns, boils, eczema, hair care (dandruff and hair loss), scars, wrinkles.
Circulation Muscles And Joints: Aching limbs, arthritis, cramp, gout, high blood pressure, muscle spasm.
Digestive System: Indigestion, heartburn.
Respiratory System: Bronchitis, colds, congestion, fever, sinusitis.
Genito-Urinary System: Menstrual cramps, PMS, hot flushes and mood fluctuations.
Immune System: Helps fight infections.
Nervous System: Anxiety, insomnia, hypertension, stress, soothes the heart.
OTHER USES: Fenugreek has three culinary uses: as a herb (dried or fresh leaves), as a spice (seeds), and as a vegetable (fresh leaves, sprouts, and microgreens). It is a popular ingredient in the preparation of Indian pickles, vegetable dishes, daals and spice mixes. Fresh fenugreek leaves are used in some Indian curries, while the sprouted seeds and microgreens are used in salads. The leaves are also used in Persian and Ethiopian cuisine, to produce a yellow dye and as a forage plant. The oil is commonly used in the perfumery and pharmaceutical industry.... fenugreek
FAMILY: Myrtaceae
SYNONYMS: Taxandria fragrans, coarse tea-tree.
GENERAL DESCRIPTION: Agonis is a genus comprising four species, all of which are native to Western Australia. The species generally have fibrous, brown bark, dull green leaves and inflorescences of small, white flowers. They are best known and most readily identified by the powerful peppermint or eucalyptus-like odour emitted when the leaves are crushed or torn. A. fragrans is a small shrub which grows up to 2.5 metres high, with narrow leaves and clusters of small white flowers, characteristic of the genus.
DISTRIBUTION: As a wild native species, fragonia (A. fragrans) has limited distribution in Western Australia, growing near the coast in the south-west region and being reliant on its winter rains and drier summers. For commercial purposes, A. fragrans is grown in large plantations in south-western Australia.
OTHER SPECIES: The Myrtaceae is a large family of plants with over 3,000 species. It is one of the most important families from an aromatherapy perspective, as it includes not only members of the Agonis genus (which includes trees such as A. flexuosa, the Western Australian peppermint) but also hundreds of aromatic plants from the Eucalyptus, Leptospermum, Melaleuca, Myrtus and Pimenta genera. There are several varying chemotypes of A. fragrans, but fragonia essential oil has a unique balance of primary constituents, which imparts its particular therapeutic qualities.
HERBAL/FOLK TRADITION: The name Agonis derives from the Greek agon, meaning ‘gathering’ or ‘collection’, in reference to the tightly clustered flowers. Traditional knowledge on A. fragrans has never been recorded, and there is no known use of the plant by early settlers. The species only came to the forefront at around the turn of the century when a husband-and-wife team heard about the local plant and began to explore its potential. Having selected superior genetic varieties, they established a small plantation of these shrubs on their property in south-west Western Australia in 2001. The essential oil distilled from this specific plant and chemotype is thus relatively new to the aromatherapy industry. Indeed it has only recently been given its common name ‘fragonia’ by its discoverer Chris Robinson, and has since been trademarked as FragoniaTM. In a series of tests, the University of Western Australia demonstrated that fragonia oil has anti-inflammatory properties and significant anti-microbial activity, similar to tea tree oil.
ACTIONS: Analgesic (mild), antibacterial, anti-inflammatory, antifungal, antimicrobial, anti-infectious, antiseptic, expectorant, immuno-tonic, nervine, regulating.
EXTRACTION: An essential oil by steam distillation from the stems, twigs and leaves.
CHARACTERISTICS: A pale, watery liquid with a pleasant slightly citrus, fresh-clean and faintly medicinal top note, mixed with a slight spicy, earthy and balsamic undertone: more pleasing than tea tree. It blends well with niaouli, eucalyptus, myrtle, lemon myrtle, rosemary and tea tree.
PRINCIPAL CONSTITUENTS: Primary constituents are 1,8-cineole, alpha-pinene and linalool. From a chemical perspective, it is an extremely well-balanced oil, with the oxides (1,8-cineole), monoterpenes (alpha-pinene) and monoterpenols (linalool, geraniol, terpineol and others) in a near perfect 1:1:1 ratio.
SAFETY DATA: Fragonia essential oil is non-toxic, non-irritant and non-sensitizing: an extremely mild oil when applied to the skin and safe for children.
AROMATHERAPY/HOME: USE:
Skin Care: Cuts, bites, stings and general skin care.
Circulation Muscles And Joints: Aching muscles and joints, arthritis, rheumatism.
Respiratory System: Asthma, bronchitis, coughs, colds, influenza, sinusitis, tonsillitis.
Genito-Urinary System: Candida (thrush), menstrual pain and breast tenderness, vaginitis.
Immune System: Powerful immune-system tonic and restorative.
Nervous System: Anxiety, depression, emotional blockages, grief, insomnia, nervous debility and tension, mood swings, stress.
OTHER USES: Many Agonis species are used as decorative garden plants while sprigs of the white flowers of A. fragrans are cut and used in the florist industry. Fragonia oil is now being used in the phyto-cosmetic industry, e.g. for soaps and skin care products. The oil can also be used as a natural, fresh-smelling disinfectant around the home, e.g. as a room fragrance, in the laundry and for cleaning bathroom and kitchen surfaces.... fragonia
FAMILY: Zygophyllaceae
SYNONYMS: Champaca wood (oil), ‘palo santo’.
GENERAL DESCRIPTION: A small, wild tropical tree up to 4 metres high, with a decorative hard wood.
DISTRIBUTION: Native to South America, especially Paraguay and Argentina. Some oil is distilled in Europe and the USA.
OTHER SPECIES: Distinct from guaiac gum and guaiac resin, known as guaiacum, obtained from related trees Guaiacum officinale and G. sanctum. However, they are somewhat similar products and share common properties.
HERBAL/FOLK TRADITION: The wood is much used for ornamental carving. It was formerly used for treating rheumatism and gout; guaiacum is still current in the British Herbal Pharmacopoeia as a specific for rheumatism and rheumatoid arthritis. Valnet includes guaiacum in his ‘elixirs’ for gout, venereal disease and in mouthwashes.

FAMILY: Apocynaceae
SYNONYMS: P. acuminate, P. acutifolia, common frangipani, temple tree, pagoda tree, graveyard tree, temple flower, may flower, frangipane, plumeria, melia.
GENERAL DESCRIPTION: Plumeria is a genus of 7–8 species native to tropical and subtropical Americas consisting mainly of deciduous shrubs and trees. P. rubra (and variation P. acutifolia) is the commonest frangipani species and has the most fragrant flowers. P. rubra is a small tree up to 5 metres tall with a ‘candelabrum’ shape, having a single trunk and branches that spread to form an open canopy. The deciduous pointed leaves, dark green on top and a lighter shade underneath, cluster at the tips of branches. The greyish-green, scaly bark produces a milky, sticky sap that is poisonous, much like oleander. The frangipani flowers which appear in clusters, each with five waxy petals, are most fragrant at night in order to lure moths to pollinate them. The species P. rubra comes in many colours: white, cream, yellow, orange, pink and red, usually with a contrasting centre.
DISTRIBUTION: P. rubra is native to tropical Central America, Venezuela, Brazil and Mexico, although it is now widely cultivated throughout the world in tropical and sub-tropical regions. In Hawaii it grows so abundantly that many people think that it is indigenous to the island. The frangipani tree is also very popular on the island of Bali, where it is planted in almost every village temple and, as in Hawaii, plays an important part in the local culture. Many countries have given a traditional name to this decorative aromatic species, such as ‘pagoda tree’ in India, ‘temple flower’ in Sri Lanka and ‘melia’ in Hawaii. In Indonesia, where the flower is associated with Balinese culture, it is known as ‘kamboja’. Now it has become naturalized throughout southern and southeastern Asia and can also commonly be found growing in the southern Mediterranean, for example in the Canary Islands.
OTHER SPECIES: P. rubra is the source of many Plumeria hybrid cultivars. In the past, the different flower colours of this plant were associated with distinct species but are now regarded as different forms of the same species. However, the white-flowered form of P. rubra is sometimes misidentified as P. alba, a rarely cultivated species endemic to the Lesser Antilles and Puerto Rico. Other popular species in the genus include P. obtusa or the evergreen frangipani (with leaves more rounded than those of P. rubra) and the white- or cream-flowered P. stenophylla which blooms heavily over a long period.
HERBAL/FOLK TRADITION: The genus Plumeria is attributed to Charles Plumier, a seventeenth-century French botanist who described several tropical species. The common name, ‘frangipani’, comes from the Italian nobleman, Marquis Frangipani, who created a perfume used to scent gloves in the sixteenth century. Frangipani is known as the ‘tree of life’, according to ancient Indian belief, and is associated with temples in both Hindu and Buddhist cultures. In India, the frangipani is considered to be a symbol of immortality because of its ability to produce leaves and flowers even after it has been lifted out of the soil. It is regarded as a sacred tree in Laos and every Buddhist temple in the country has frangipani planted in their courtyards. In Cambodia, the flowers are used in ritual offerings to the deities and Balinese Hindus use the flowers in their temple offerings daily. In several Pacific islands, such as Tahiti, Fiji, Samoa and Hawaii, Plumeria species are used for making leis, their traditional flower garlands. In modern Polynesian culture, the flowers are also worn by women to indicate their relationship status.
Frangipani has also been celebrated for centuries for its healing capacity in many diverse cultures. In Sri Lanka, Plumeria flowers are eaten as fritters, while the heart of the wood is taken as a vermifuge or as a laxative. In Ayurveda, the Plumeria species are widely used as a purgative, as a remedy for diarrhoea, to treat itch, asthma, coughs, bronchitis, blood disorders and fever. In the Guianas, P. rubra is used for the treatment of skin eruptions, abscesses, dysentery, herpes, coughs and as a purgative. In Caribbean cultures, the leaves are used as a healing wrap for bruises and ulcers while the latex is used as a liniment for rheumatism. In Vietnam, the bark mashed in alcohol, is used to combat skin inflammation, indigestion and high blood pressure. Frangipani flower tea is also generally believed to have a beneficial effect, being good for digestion.
ACTIONS: Anti-inflammatory, anti-oxidant, antimicrobial, antifungal, anti-tumoral, antiviral, aphrodisiac, astringent, nervine.
EXTRACTION: Frangipani absolute is obtained by alcoholic or solvent extraction from the concrete prepared from P. rubra (acutifolia). The absolute has a thick, treacle consistency at room temperature.
CHARACTERISTICS: The absolute has a heavy, sweet, floral-green aroma, with a soft-spicy background and hints of apricot. It blends with sandalwood, rose, patchouli, tuberose, clove bud, jasmine, neroli, bergamot, ginger, ylang ylang and most citrus oils.
PRINCIPAL CONSTITUENTS: The oil of .P obtusa is rich in benzyl salicylate (45.4 per cent) and benzyl benzoate (17.2 per cent) Oil obtained from P.acuminata is rich in palmitic acid (36.2 per cent), linoleic acid (16.8 per cent), lauric acid (10.4 per cent) and myristic acid (10.3 per cent). ‘The pink flowered P. rubra oil was similar to P. acuminata oil in that it was also devoid of benzyl salicylate and benzyl benzoate and rich in alkanoic acids but linoleic acid was absent in the oil of the former. However, the orange-flowered P. rubra oil contained both the non-terpene esters (benzyl salicylate, benzyl benzoate and 2-phenylethyl benzoate) and alkanoic acids in significant amounts.’.
SAFETY DATA: Generally considered to be a safe oil, but best avoided in pregnancy and for children. May cause skin irritation in concentration.

FAMILY: Ericaceae
SYNONYMS: Ledum, Labrador tea, marsh tea, swamp tea, bog Labrador tea, rusty Labrador tea, Hudson’s Bay tea (formerly Ledum groenlandicum).
GENERAL DESCRIPTION: This beautiful, hardy plant is a shrub belonging to the heather family, which can reach one metre in height. It is recognizable by its thick, leathery evergreen leaves whose edges coil under and are quite unique, being deep green on top with a downy-fuzz beneath. New leaves have a woolly mat of white hairs underneath; mature leaves have reddish hairs. All leaves are dotted with resinous glands and are fragrant, with a pungent scent, when crushed. The fluffy white flowers, which are borne in spring, are also strongly aromatic.
DISTRIBUTION: The plant is native to North America, from Greenland and Labrador across to Alaska, as far north as the treeline. It is absent from the far North and the dry prairies. The Latin name groenlandicum refers to the fact that it grows in Greenland where it is still widespread, often growing in dense colonies.
OTHER SPECIES: Ledum is a genus name, which includes 8 species of evergreen shrubs native to cool temperate and sub-arctic regions of the Northern Hemisphere, commonly known as Labrador tea. The common name Ledum is also applied to Rhododendron tomentsum subsp. subarcticum (formerly L. decumbens) which is known as Northern Labrador tea. This species, which is similar but slightly smaller, grows farther north on tundra at up to 1,800 metres and contains toxic alkaloids known to be poisonous to livestock. It lacks the characteristic fuzz on the underside of the mature leaves and the flowers of L. groenlandicum.
HERBAL/FOLK TRADITION: This strongly aromatic herb has been used in folk medicine for centuries. Brewed as a medicinal beverage known as Labrador tea, it was used by practically all Canada’s First Nations peoples as a tonic and to treat certain respiratory, digestive and kidney ailments; as a remedy for headaches and various types of rheumatism; and to facilitate childbirth. The herbal tea also served to clean wounds and was applied to insect bites. It is said that the plant was used for over 5,000 years by the native people of North America, to protect themselves from scurvy, and the Cree used it for fevers and colds: indeed it was regarded as a ‘cure-all’ by the indigenous people. In the fur-trading era, the French Canadian coureurs-de-bois used Labrador tea to extend their supplies of black tea: it thus became a substitute for unaffordable Chinese tea during times of economic crisis. However, like other plants in the heather family, Greenland moss contains an andromedo-toxin that can cause poisoning if used in excess.
According to recent clinical trials, Greenland moss essential oil has a natural affinity for the immune system and can be an effective immune system supporter. The oil also helps counteract blood toxicity and aids liver regeneration, valuable in cases of liver intoxication originating from circulation disorders, viral hepatitis, enteritis and cirrhosis (fatty liver). Clinical research suggests that the essential oil functions like an enzyme in the liver, digesting toxic waste and fat molecules. It is also indicated for obesity, oedema, water retention and thyroid regulation. The oil has also been studied at the University of Quebec, and was found to be a strong antioxidant and natural anti-inflammatory: it also showed anticancer activity against colon carcinoma and lung carcinoma cells.
ACTIONS: Analgesic, antibacterial, anticancerous, antiviral, anti-inflammatory, anti-tumoral, antispasmodic, antioxidant, anti-infectious, antiseptic, carminative, cicatrizing, decongestant, digestive tonic, immune support, liver support, stomachic, tonic.
EXTRACTION: Greenland moss oil is extracted by steam distillation from the leaves.
CHARACTERISTICS: A clear, pale-yellow liquid, with a fresh-herbaceous, medicinal and slightly sweet aroma and earthy-woody undertones.
PRINCIPAL CONSTITUENTS: The main chemical constituents are limonene (up to 35 per cent), sabinene, selinene, bornyl acetate with other monoterpenes and sesquiterpenes.
SAFETY DATA: Possible skin sensitization: always dilute for topical use. Avoid during pregnancy and by children. NB: Abusive consumption of the tea derived from its leaves may cause indigestion, and may even have a toxic effect due to the high level of tannins that it contains.

FAMILY: Asteraceae
SYNONYMS: Gumweed, hardy grindelia, gum plant, scaly grindelia, rosin weed, curlytop gumweed, curlycup gumweed, tarweed, resin-weed, sticky-heads.
GENERAL DESCRIPTION: A biennial or short-lived perennial up to one metre high with yellow, daisy-like flower heads, each with overlapping rows of backward-curling, bracts: squarrosa is Latin for ‘scaly or rough’, referring to these curling bracts. The leaves are dotted with resinous glands: thus many common names for Grindelia squarrosa, such as gumweed, refer to the gooey resin that they exude, which has a sweet incense-like scent. This white viscous gum may cover the entire bud top and flowers, which bloom in late summer from July to September. However, the dried flowering heads may persist for several years due to the preservative action of the gummy resin!
DISTRIBUTION: This plant is native to western North America and Mexico. It is naturalized in eastern North America and the Pacific Coast states: several species are also cultivated as ornamentals in Europe.
OTHER SPECIES: Grindelia comprises about 60 species: the name of the genus honours the Russian botanist, David Grindel. All are native to North and Central America and chiefly distributed in warm-temperate regions. Several species are used to produce essential oils, including G. oregana and G. robusta as well as G. squarrosa. All these oils were found to contain alpha-pinene, ?-pinene, limonene, borneol, bornyl acetate trans-pinocarveol and germacrene D as the main constituents and only showed small differences in chemical composition. However, menthol, menthone and pulegone were detected only in the essential oil of G. oregano.
HERBAL/FOLK TRADITION: Grindelia has been used as a traditional herbal remedy by indigenous cultures all over the Americas for centuries. The plant was harvested when in full bloom and used fresh as a poultice or herbal extract or dried for infusions etc. The herb was used by Great Plains Tribes mainly to treat respiratory problems, such as asthma, colic, coughs and bronchitis, especially among the aged; the leaves were smoked to relieve spasmodic asthma. Externally, the crushed flowers were used to make poultices, which was applied to burns, rashes, poison ivy, blisters, dermatitis, eczema, saddle sores and raw skin. The leaves and flowering tops was used to make an herbal tea used to relieve coughs and dizziness. The sticky sap was chewed as gum and herbal extracts were also used to treat rheumatic conditions. Spanish New Mexicans would also drink a tea made from boiling the flower buds in water, for treating kidney problems. The Eclectic School of Medicine used Grindelia externally to promote skin regrowth and to heal reluctant, persistent ulcers.
The medicinal value of this plant was not recognized by the orthodox practitioners of medicine in the US till the middle of the nineteenth century, after which it came into prominence as a major medicinal plant. Official recognition of Grindelia came with the introduction of the herb in the Pharmacopoeia of the United States in 1882. It is still listed in the U.S. Dispensatory, and is currently used by modern Americans in the treatment of colds, hay fever, nasal congestion, whooping cough, bronchial catarrh, asthma etc. It is current in the German Commission E for catarrh of the upper respiratory tract and the British Pharmacopoeia also lists the antispasmodic, expectorant and cardiac depressant properties of this herb. The positive effects of this herb on the relief of symptoms of common cold have been recognized empirically. Indeed recent studies have shown it to have good expectorant and antispasmodic as well as moderate anti-inflammatory and antibiotic effects. It also appears to aid allergenic attacks, not only by relieving the symptoms but in creating anti-bodies to reduce episodes and their severity. Secondary uses include the treatment of cystitis and fever, usually in combinations with other herbs. It is also indicated externally in lotion form for the treatment of eczema, dermatitis and rashes due to poison ivy, hives etc.
ACTIONS: Anti-asthmatic, antibacterial, antidepressant, antihistamine, anti-inflammatory, antimicrobial, antiseptic, antispasmodic, astringent, cooling, decongestant, emetic, expectorant, immune support, mucolytic, regenerative, sedative.
EXTRACTION: The essential oil is steam distilled from the flowering plant.
CHARACTERISTICS: A mobile liquid with a strong, earthy-herbaceous, medicinal and slightly camphoraceous odour. It blends well with eucalyptus, ravintsara, myrtle, pine, cypress and peru balsam.
PRINCIPAL CONSTITUENTS: Alpha-pinene (aprox. 25 per cent) is the major constituent, with ?-pinene, limonene, borneol, bornyl acetate and germacrene D. Data is lacking regarding the interaction of the chemistry of the aromatic resin and the volatile oils.
SAFETY DATA: No adverse effects have been reported in the literature regarding the safety of Grindelia in the case of therapeutic application. However, data is lacking regarding the essential oil specifically.

SYNOYNMS Ho oil, ho-wood il, shiu oil, ho-leaf oil.
GENERAL DESCRIPTION: A tall, tropical evergreen tree, quite dense with small white flowers and black berries, which grows up to 30 metres in height. This is the same tree that produces camphor comes from the wood of the tree.
DISTRIBUTION: Native to China, Japan, Taiwan and south-east Asia. It is now cultivated in many tropical and sub-tropical countries including India, Australia, Madagascar and parts of the USA where it has naturalized.
OTHER SPECIES: Cinnamomum camphora is a large genus with many subspecies which yield a volatile oil on distillation, including ho oil (wood and leaf), camphor, apopin, sassafras and ravintsara. All these essential oils, although derived from the same principal botanical species, differ in their chemical profile enormously depending on their country of origin as well as the part of the plant used to extract the oil. There are thus many different subvarieties of the camphor tree found throughout Asia, for example the Yu-sho in China and the Sho-guy variety found in Taiwan. Ho (wood and leaf) oil is derived both from the Hon-sho and Ho-sho varieties growing mainly in Japan and Taiwan. This variety has linalool as its major constituent.
Rosewood (Aniba rosaedora), a native tree of the Amazon, also yields an oil very rich in linalool. However, rosewood became endangered due to over-harvesting and although plantations have since been planted, it will take time for the trees to mature. Rosewood oil and ho wood oil are very similar in nature, and since ho wood is more renewable, it is increasingly used as a replacement for the former. However, ho leaf oil, distilled from the leaves of C. camphora, is gradually beginning to replace ho wood oil in aromatherapy usage, because its scent is smoother, containing hardly any camphor-like notes.
HERBAL/FOLK TRADITION: Ho wood has traditionally been used for making the handles of Japanese swords and knives because it is soft and will not scratch the blades. It is also used nowadays for ornamental parts of houses, carpentry and cabinet making, as it is of a very similar beauty to rosewood. Ho wood oil became very popular in Taiwan during the 1900s as a linalool-rich product, locally referred to as shiu oil. C. camphora was also heavily exploited as a source of camphor in Japan and Taiwan until World War II.
The high ‘linalool’ content makes Ho oil a potent immune system stimulant (good for infections such as cold or ’flu) as well as a powerful relaxant or sedative … soothing yet uplifting in effect. Recent studies also suggest that the oil may play a role as a cellular stimulant and tissue regenerator, being beneficial for complaints associated with the skin.
ACTIONS: Analgesic, anti-fungal, anti-infectious, anti-inflammatory, anti-oxidant, antiseptic, antispasmodic, bactericidal, immune support, sedative, tonic. It is also believed to be a mild aphrodisiac.
EXTRACTION: Steam distilled from the leaves (ho leaf oil) and wood (ho wood oil)
CHARACTERISTICS: Ho wood oil is a pale yellow liquid with a soft, warm, floral, spicy-woody scent with a slightly camphor-like undertone. The leaf oil has a sweet-fresh, green-floral and woody scent. It blends well with basil, bergamot, cedarwood, chamomile, lavender, lime, geranium, juniper, neroli, petitgrain, myrtle, sandalwood, ylang ylang and spice oils.
PRINCIPAL CONSTITUENTS: Ho (wood and leaf) oil contains up to 99 per cent linalool, with traces of limonene, myrcene, gamma-terpinene and other components. Ho wood oil generally contains higher levels of cineol. Japanese ho oil ‘A’ quality has a linalool content of 94 per cent or more; a ‘B’ grade has 85–90 per cent linalool.
SAFETY DATA: It is non-toxic and non-irritant but with possible sensitization in some individuals.
AROMATHERAPY/HOME: USE

Nervous System: Anxiety, depression, insomnia, nervous tension, stress.
OTHER USES: The use of C. camphora as a source of ho leaf and wood oil has expanded in recent years and it is now an important source of natural linalool (which is still preferred over the synthetic form) for some fragrance applications in the perfumery industry. Indeed, ho leaf and wood oil has largely displaced the use of rosewood as a source of natural linalool. It is also an effective insect repellent.... ho wood
