Exudation Health Dictionary

A localised collection of pus. A minute abscess is known as a PUSTULE; a di?used production of pus is known as CELLULITIS or ERYSIPELAS. An abscess may be acute or chronic. An acute abscess is one which develops rapidly within the course of a few days or hours. It is characterised by a de?nite set of symptoms.

Causes The direct cause is various BACTERIA. Sometimes the presence of foreign bodies, such as bullets or splinters, may produce an abscess, but these foreign bodies may remain buried in the tissues without causing any trouble provided that they are not contaminated by bacteria or other micro-organisms.

The micro-organisms most frequently found are staphylococci (see STAPHYLOCOCCUS), and, next to these, streptococci (see STREPTOCOCCUS) – though the latter cause more virulent abscesses. Other abscess-forming organisms are Pseudomonas pyocyanea and Escherichia coli, which live always in the bowels and under certain conditions wander into the surrounding tissues, producing abscesses.

The presence of micro-organisms is not suf?cient in itself to produce suppuration (see IMMUNITY; INFECTION); streptococci can often be found on the skin and in the skin glands of perfectly healthy individuals. Whether they will produce abscesses or not depends upon the virulence of the organism and the individual’s natural resistance.

When bacteria have gained access – for example, to a wound – they rapidly multiply, produce toxins, and cause local dilatation of the blood vessels, slowing of the bloodstream, and exudation of blood corpuscles and ?uid. The LEUCOCYTES, or white corpuscles of the blood, collect around the invaded area and destroy the bacteria either by consuming them (see PHAGOCYTOSIS) or by forming a toxin that kills them. If the body’s local defence mechanisms fail to do this, the abscess will spread and may in severe cases cause generalised infection or SEPTICAEMIA.

Symptoms The classic symptoms of in?ammation are redness, warmth, swelling, pain and fever. The neighbouring lymph nodes may be swollen and tender in an attempt to stop the bacteria spreading to other parts of the body. Infection also causes an increase in the number of leucocytes in the blood (see LEUCOCYTOSIS). Immediately the abscess is opened, or bursts, the pain disappears, the temperature falls rapidly to normal, and healing proceeds. If, however, the abscess discharges into an internal cavity such as the bowel or bladder, it may heal slowly or become chronic, resulting in the patient’s ill-health.

Treatment Most local infections of the skin respond to ANTIBIOTICS. If pus forms, the abscess should be surgically opened and drained.

Abscesses can occur in any tissue in the body, but the principles of treatment are broadly the same: use of an antibiotic and, where appropriate, surgery.... abscess

Linn.

Family: Hippocastanaceae; Sapinda- ceae.

Habitat: Endemic to the mountains of Balkan Peninsula and western Asia. Introduced into India; occasionally grown as an ornamental tree.

English: Horse Chestnut tree.

Unani: Baloot. (Quercus incana and Q. infectoria have also been equated with Baloot in National Formulary in Unani Medicine.)

Folk: Pu.

Action: Anti-inflammatory, vasodilator, astringent (used for rheumatism, venous congestion, haemorrhoids), febrifuge. Leaf— used in whooping cough.

Key application: In chronic venous insufficiency, varicosis, nocturnal systremma (cramps in the calves) and swelling of the legs. (Non- invasive treatment measures should also be followed.) (German Commission E, ESCOP, The British Herbal Pharmacopoeia.)

Horse Chestnut contains triterpe- noid saponins (especially aescin, a complex mixture composed of acylat- ed glycosides of protoaesigenin and barringtogenol-C, including hippo- caesculin), coumarins and flavonoids. Aescin has been shown to eliminate oedema and reduce exudation. It antagonizes the effect of bradykinin, although it is not a direct bradykinin antagonist. It causes an increase in plasma levels of ACTH, corticosterone and glucose in rats. Hippocaescu- lin and barringtogenol-C-21-angelate show antitumour activity in vitro.

The hydroxycoumarin aesculin leads to increased bleeding time. (Roasting seems to destroy the toxins.) A few fruits can cause severe toxic symptoms. (Francis Brinker.) In some countries, an intravenous mixture containing aescin is used after surgery. (Natural Medicines Comprehensive Database, 2007.)... aesculus hippocastanum

Commiphora mukul

Burseraceae

San: Gugulu, Mahisaksah, Koushikaha, Devadhupa

Hin: Gugal Mal:Gulgulu Tam,

Tel: Gukkulu

Kan: Guggul

Ben: Guggul

Importance: Indian bdellium is a small, armed, deciduous tree from the bark of which gets an aromatic gum resin, the ‘Guggul’ of commerce. It is a versatile indigenous drug claimed by ayurvedists to be highly effective in the treatment of rheumatism, obesity, neurological and urinary disorders, tonsillitis, arthritis and a few other diseases. The fumes from burning guggul are recommended in hay- fever, chronic bronchitis and phytises.

The price of guggulu gum has increased ten fold in ten years or so, indicating the increase in its use as well as decrease in natural plant stand. It has been listed as a threatened plant by Botanical Survey of India (Dalal, 1995) and is included in the Red Data Book (IUCN) and over exploited species in the country (Billare,1989).

Distribution: The center of origin of Commiphora spp. is believed to be Africa and Asia. It is a widely adapted plant well distributed in arid regions of Africa (Somalia, Kenya and Ethiopia in north east and Madagascar, Zimbabwe, Botswana, Zaire in south west Africa), Arabian peninsula (Yemen, Saudi Arabia and Oman). Different species of Commiphora are distributed in Rajasthan, Gujarat, Maharashtra and Karnataka states of India and Sind and Baluchistan provinces of Pakistan (Tajuddin et al, 1994). In India, the main commercial source of gum guggul is Rajasthan and Gujarat.

Botany: The genus Commiphora of family Burseraceae comprises about 185 species. Most of them occur in Africa, Saudi Arabia and adjoining countries. In India only four species have been reported. They are C. mukul(Hook. ex Stocks) Engl. syn. Balsamodendron mukul (Hook. ex Stocks), C. wightii (Arnott) Bhandari, C.stocksiana Engl., C. berryi and C.agallocha Engl.

In early studies about the flora of India, the ‘guggul’ plant was known as Commiphora mukul(Hook. ex Stocks) Engl. or Balsamodendron mukul (Hook. ex Stocks). It was renamed as C. roxburghii by Santapau in 1962. According to Bhandari the correct Latin name of the species is C. wightii(Arnott) Bhandari, since the specific name ‘wightii’ was published in 1839, prior to ‘roxburghi’ in 1848 (Dalal and Patel, 1995).

C. mukul is a small tree upto 3-4m height with spinescent branching. Stem is brownish or pale yellow with ash colored bark peeling off in flakes. Young parts are glandular and pubescent. Leaves are alternate, 1-3 foliate, obovate, leathery and serrate (sometimes only towards the apex). Lateral leaflets when present only less than half the size of the terminal ones. Flowers small, brownish red, with short pedicel seen in fascicles of 2-3. Calyx campanulate, glandular, hairy and 4-5 lobed. Corolla with brownish red, broadly linear petals reflexed at apex. Stamens 8-10, alternatively long and short. Ovary oblong, ovoid and stigma bifid. Fruit is a drupe and red when ripe, ovate in shape with 2-3 celled stones. The chromosome number 2n= 26 (Warrier et al, 1994; Tajuddin et al, 1994).

Agrotechnology: Guggal being a plant of arid zone thrives well in arid- subtropical to tropical climate.

The rainfall may average between 100mm and 500mm while air temperature may vary between 40 C in summer and 3 C during winter. Maximum relative humidity prevails during rainy season (83% in the morning and 48% in the evening).Wind velocity remains between 20-25 km/hour during the year is good. Though they prefer hard gypseous soil, they are found over sandy to silt loam soils, poor in organic matter but rich in several other minerals in arid tracks of western India (Tajuddin et al, 1994).

Plants are propagated both by vegetatively and seeds. Plants are best raised from stem cuttings from the semi woody (old) branch. For this purpose one metre long woody stem of 10mm thickness is selected and the cut end is treated with IBA or NAA and planted in a well manured nursery bed during June-July months; the beds should be given light irrigation periodically. The cuttings initiate sprouting in 10-15 days and grow into good green sprout in 10-12 months. These rooted plants are suitable for planting in the fields during the next rainy season. The cuttings give 80-94% sprouting usually. Air layering has also been successfully attempted and protocol for meristem culture is available in literature. Seed germination is very poor (5%) but seedling produce healthier plants which withstand high velocity winds.

The rooted cuttings are planted in a well laid-out fields during rainy season. Pits of size 0.5m cube are dug out at 3-4 m spacing in rows and given FYM and filler soil of the pit is treated with BHC (10%) or aldrin (5%) to protect the new plants from white ants damage. Fertilizer trials have shown little response except due to low level of N fertilization. Removal of side branches and low level of irrigation supports a good growth of these plants. The plantation does not require much weeding and hoeing. But the soil around the bushes be pulverised twice in a year to increase their growth and given urea or ammonium sulphate at 25- 50g per bush at a time and irrigated. Dalal et al (1989) reported that cercospora leaf spot was noticed on all the cultures. Bacterial leaf blight was also noticed to attack the cultures. A leaf eating caterpillar (Euproctis lanata Walker) attack guggal, though not seriously. White fly (Bemisia tabaci) is observed to suck sap of leaves and such leaves become yellowish and eventually drop. These can be effectively controlled by using suitable insecticide.

Stem or branch having maximum diameter of about 5cm at place of incision, irrespective of age is tapped. The necrotic patch on the bark is peeled off with a sharp knife and Bordeaux paste is applied to the exposed (peeled off) surface of the stem or branch. A prick chisel of about 3cm width is used to make bark- deep incisions and while incising the bark, the chisel is held at an acute angle so that scooped suspension present on the body of the chisel flows towards the blade of the chisel and a small quantity of suspension flows inside the incised bark. If tapping is successful, gum exudation ensures after about 15-20 days from the date of incision and continues for nearly 30-45 days. The exuded gum slides down the stem or branch, and eventually drops on the ground and gets soiled. A piece of polythene sheet can be pouched around the place of incision to collect gum. Alternatively, a polythene sheet can be spread on the ground to collect exuded gum. A maximum of about 500g of gum has been obtained from a plant (Dalal, 1995).

Post harvest technology: The best grade of guggul is collected from thick branches of tree. These lumps of guggul are translucent. Second grade guggul is usually mixed with bark, sand and is dull coloured guggul. Third grade guggul is usually collected from the ground which is mixed with sand, stones and other foreign matter. The final grading is done after getting cleansed material. Inferior grades are improved by sprinkling castor oil over the heaps of the guggul which impart it a shining appearance (Tajuddin et al, 1994).

Properties and activity: The gum resin contains guggul sterons Z and E, guggul sterols I-V, two diterpenoids- a terpene hydrocarbon named cembreneA and a diterpene alcohol- mukulol, -camphrone and cembrene, long chain aliphatic tetrols- octadecan-1,2,3,4-tetrol, eicosan-1,2,3,4-tetrol and nonadecan-1,2,3,4-tetrol. Major components from essential oil of gum resin are myrcene and dimyrcene. Plant without leaves, flowers and fruits contains myricyl alcohol, -sitosterol and fifteen aminoacids. Flowers contain quercetin and its glycosides as major flavonoid components, other constituents being ellagic acid and pelargonidin glucoside (Patil et al, 1972; Purushothaman and Chandrasekharan, 1976).

The gum resin is bitter, acrid, astringent, thermogenic, aromatic, expectorant, digestive, anthelmintic, antiinflammatory, anodyne, antiseptic, demulcent, carminative, emmenagogue, haematinic, diuretic, lithontriptic, rejuvenating and general tonic. Guggulipid is hypocholesteremic (Husain et al, 1992; Warrier et al, 1994).... indian bdellium

In?ammation of the PLEURA or serous membrane investing the lung and lining the inner surface of the ribs. It is a common condition, and may be either acute or chronic, the latter being usually tuberculous in origin (see TUBERCULOSIS).

Many cases of pleurisy are associated with only a little e?usion, the in?ammation consisting chie?y in exudation of FIBRIN: to this form the term ‘dry pleurisy’ is applied. Further, pleurisy may be limited to a very small area – or, on the contrary, may affect, throughout a greater or less extent, the pleural surfaces of both lungs.

Causes Pleurisy is often associated with other forms of in?ammatory disease within the chest, more particularly PNEUMONIA, BRONCHIECTASIS, and tuberculosis; it occasionally accompanies PERICARDITIS. It may also be due to carcinoma of the lung, or be secondary to abdominal infections such as subphrenic abscess. Further, wounds or injuries of the thoracic walls are apt to set up pleurisy.

Symptoms The symptoms of pleurisy vary, being generally well marked, but sometimes obscure. DRY PLEURISY In the case of dry pleurisy, which is, on the whole, the milder form, the chief symptom is a sharp pain in the side, felt especially on breathing. Fever may or may not be present. There is a slight, dry cough, and breathing is quicker than normal and shallow. PLEURISY WITH EFFUSION is usually more severe than dry pleurisy, and, although it may in some cases develop insidiously, it is in general ushered in sharply by shivering and fever, like other acute in?ammatory diseases. Pain is felt in the side or breast, of a severe cutting or stabbing character. A dry cough usually occurs and breathing is painful and di?cult.

Treatment The treatment varies greatly with the form and severity of the attack. Bed rest, antibiotics, analgesics and antipyretics are advisable. A large pleural e?usion may need to be drained via an aspiration needle.... pleurisy

Skin cancer Primary cancer is common and chronic exposure to ultraviolet light is the most important cause. BASAL CELL CARCINOMA is the most common form; squamous cell carcinoma is less common and presents as a growing, usually painless nodule which may ulcerate. Squamous cancer may spread to regional lymph glands and metastasise, unlike basal cell cancer. Occupational exposure to chemical carcinogens may cause squamous carcinoma – for example, cancer from pitch warts or the scrotal carcinoma of chimney sweeps exposed to coal dust in earlier centuries. Squamous carcinoma of the lip is associated with clay-pipe smoking.

Cancer may arise from the population of melanocytes of the skin (see MELANOCYTE; MELANOMA).

Apart from these three most frequent forms of skin cancer, various forms of cancer can arise from cells of the dermis, of which LYMPHOMA is the most important (see also MYCOSIS FUNGOIDES).

Lastly, secondary deposits from internal cancer, particularly from the breast, may metastasise to the skin.

Dermatitis and eczema These are broadly synonymous, and the terms are frequently interchangeable. Eczema is a pattern of in?ammation with many potential causes. Dermatitis is commonly used to suggest an eczema caused by external factors; it is a common pattern of in?ammation of the skin characterised by redness and swelling, vesiculation (see VESICLE), and scaling with intense itching and often exudation (weeping). Fissuring, thickening (licheni?cation – see LICHEN) and secondary bacterial infection may follow. Dermatitis can affect any part of the body. It may be genetically detemined or due to other ‘internal’ factors, such as venous HYPERTENSION in a leg, or stress. Often it is ‘external’ in origin – due to strong irritants or chemical allergens. (See also ALLERGY; ALLERGEN.) ATOPIC DERMATITIS is genetic in origin and usually begins in infancy. It may persist for years, and ASTHMA, allergic RHINITIS and conjunctivitis (see under EYE, DISORDERS OF) – ‘hay fever’ – may be associated. Atopic children tend to have multiple allergies, especially to inhaled allergens such as house-dust mite, cat and dog dander and pollens. Allergy to foods is less common but potentially more dangerous, especially if to nuts, when it can cause acute URTICARIA or even ANAPHYLAXIS. Atopic subjects are particularly prone to persistent and multiple verrucae (see WARTS) and mollusca (see MOLLUSCUM CONTAGIOSUM) and to severe HERPES SIMPLEX infections. (See also ATOPY.)

EXFOLIATE DERMATITIS (PITYRIASIS RUBRA)

Generalised exfoliation and scaling of the skin, commonly with ERYTHEMA. Drugs may cause it, or the disorder may be linked with other skin diseases such as benign dermatoses and lupus erythematosus (see under LUPUS). SUMMER POMPHOLYX is an acute vesicular eczema of the palms and soles recurring every summer. Inhaled allergens are a frequent cause. VENOUS (STASIS) DERMATITIS begins on a lower calf, often in association with PURPURA, swelling and sometimes ulceration. Chronic venous hypertension in the leg, consequent on valvular incompetence in the deep leg veins owing to previous deep vein thrombosis (see VEINS, DISEASES OF), is the usual cause. NEURODERMATITIS A pattern of well-de?ned plaques of licheni?ed eczema particularly seen on the neck, ulnar forearms or sides of the calves in subjects under emotional stress. IRRITANT CONTACT DERMATITIS Most often seen in an industrial setting (occupational dermatitis), it is due to damage by strong chemicals such as cutting oils, cement, detergents and solvents. In almost all cases the hands are most severely affected. ALLERGIC CONTACT DERMATITIS, in contrast, can affect any part of the body depending on the cause – for example, the face (cosmetics), hands (plants, occupational allergens) or soles (rubber boots). Particularly common allergens include metals (nickel and chromate), rubber addititives, and adhesives (epoxy resins).

Treatment Avoidance of irritants and contact allergens, liberal use of EMOLLIENTS, and topical application of corticosteroid creams and ointments (see CORTICOSTEROIDS) are central.... skin, diseases of

Uses: Coughs, colds, influenza and onset of fevers generally. Traditionally a whole lemon was roasted or baked in a moderate oven for half an hour and as much juice drunk as tolerated. Sore throat (gargle). Diphtheria: impressive cures reported. Persist until false membrane is detached: Neat lemon juice gargle hourly, swallowing 1-2 teaspoons. If too strong, may be diluted. Often overlooked for hiccoughs. Dropsy: lemon fast. 3-4 days on lemon juice alone: no solid food, tea, stimulants, etc. Biliousness, sick headache: juice of a lemon morning and evening; sweeten with honey if necessary. Malaria: half a teacup juice in water every 2-3 hours. Rheumatism: juice of half lemon before meals and at bedtime; may be diluted. For rheumatism, anecdotal success has been reported by combining equal parts lemon juice and molasses: tablespoon thrice daily before meals. Cellulitis. A lemon mask helps to fade spots.

External: erysipelas, corns, lesions of scurvy. “For a felon (whitlow) cut off end of a lemon; insert finger and bind securely. In the morning remove exudation of matter.” (Chinese Barefoot doctor)

Preparations: Tincture Limonis P (1948) (dose, 2-4ml) is sometimes available but recorded successes have been chiefly due to use of the juice. Oil Lemon BP. Used also in Aromatherapy.

Note: When drinking lemon juice care should be taken to see juice does not come in direct contact with the teeth, the enamel of which it erodes. The juice may remove some calculi from the body, but after having cleared the bloodstream it leeches calcium from the teeth and bones. It is a known cause of arthritis, inducing dryness and subsequent erosion of cartilage of the joints. ... lemon

“Bread of Heaven” Tamarix mannifera, ehr. Believed to be the food of the Old-Testament Israelites during their 40 years wanderings through the wilderness. “Even to this day a “manna” falls like dew or hoar frost and lands like beads on grass, stones and twigs. It is sweet like honey and sticks to the teeth.

n. any of various disorders of the retina resulting in impairment or loss of vision. It is usually due to damage to the blood vessels of the retina, occurring (for example) as a complication of longstanding diabetes (diabetic retinopathy), high blood pressure, or AIDS (AIDS retinopathy). In diabetic retinopathy, haemorrhaging or exudation may occur, either from damaged vessels into the retina or from new abnormal vessels (see neovascularization) into the vitreous humour. The later stages require laser treatment (see photocoagulation). In the UK all people with diabetes are screened using annual digital retinal photography. The warning signs of potentially sight-threatening retinal changes can be spotted and referral to a specialist eye clinic made for further assessment and intervention to prevent a deterioration in vision. Retinopathy of prematurity (ROP), formerly known as retrolental fibroplasia, is the abnormal growth of developing retinal blood vessels seen in premature infants. It may be mild and resolve spontaneously or severe enough to lead to blindness if untreated.... retinopathy

Dryobalanops aromatica

FAMILY: Dipterocarpaceae

SYNONYMS: D. camphora, Borneo camphor, East Indian camphor, Baros camphor, Sumatra camphor, Malayan camphor.

GENERAL DESCRIPTION: The camphora tree grows to a great height, a majestic tree often over 25 metres high, with a thick trunk up to 2 metres in diameter. Borneol is a natural exudation found beneath the bark in crevices and fissures of some mature trees (about 1 per cent); young trees produce only a clear yellow liquid known as ‘liquid camphor’.

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.

PRINCIPAL CONSTITUENTS: The crude is made up of mainly cl-borneol which is an alcohol, not a ketone (like Japanese camphor). The oil contains approx. 35 per cent terpenes: pinene, camphene, dipentene; 10 per cent alcohols: d-borneol, terpineol; 20 per cent sesquiterpenes, and 35 per cent resin.

SAFETY DATA: Non-toxic, non-sensitizing, dermal irritant in concentration.

AROMATHERAPY/HOME: USE

Skin Care: Cuts, bruises, insect repellent,

Circulation Muscles And Joints: Debility, poor circulation, rheumatism, sprains.

Respiratory System: Bronchitis, coughs.

OTHER USES: It is used to scent soap in the East but is still relatively unknown in the West in pharmaceutical and perfumery work. In China and Japan it is used for making varnish and ink; also asa dilutant for artists’ colours. Mainly used for ritual purposes in the East.... borneol

Abies balsamea

FAMILY: Pinaceae

SYNONYMS: A. balsamifera, Pinus balsamea, balsam fir, balsam tree, American silver fir, balm of Gilead fir, Canada turpentine (oil).

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.

HERBAL/FOLK TRADITION: The oleoresin is used extensively by the American Indians for ritual purposes and as an external treatment for burns, sores, cuts and to relieve heart and chest pains. It is also used internally for coughs.

ACTIONS: Antiseptic (genito-urinary, pulmonary), antitussive, astringent, cicatrisant, diuretic, expectorant, purgative, regulatory, sedative (nerve), tonic, vulnerary.

EXTRACTION: 1. The oleoresin is collected by punturing vesicles in the bark. 2. An essential oil is produced by steam distillation from the oleoresin, known as Canada balsam or Canada turpentine. (An essential oil is also produced by steam distillation from the leaf or needles, known as fir needle oil.)

CHARACTERISTICS: 1. The oleoresin is a thick pale yellow or green honeylike mass which dries to crystal clear varnish, with a fresh sweet balsamic, almost fruity odour. 2. A colourless mobile liquid with a sweet, soft-balsamic, pinelike scent. It blends well with pine, cedarwood, cypress, sandalwood, juniper, benzoin and other balsams.

PRINCIPAL CONSTITUENTS: Consists almost entirely of monoterpenes, pinene, phellandrene, esters and alcohols.

SAFETY DATA: Generally non-toxic, non-irritant, non-sensitizing. ‘In large doses it is purgative and may cause nausea.’4

AROMATHERAPY/HOME: USE

Skin Care: Burns, cuts, haemorrhoids, wounds.

Respiratory System: Asthma, bronchitis, catarrh, chronic coughs, sore throat.

Genito-Urinary System: Cystitis, genito-urinary infections.

Nervous System: Depression, nervous tension, stress-related conditions – described as ‘appeasing, sedative, elevating, grounding, opening’.5

OTHER USES: The oil from the oleoresin is used in certain ointments and creams as an antiseptic and treatment for haemorrhoids. Used in dentistry as an ingredient in root canal sealers. Also used as a fixative or fragrance component in soaps, detergents, cosmetics and perfurmes. There is some low-level use in food products, alcoholic and soft drinks. The oleoresin is used as a medium in microscopy and as a cement in glassware.... balsam, canadian

SYNONYMS: Pinus canadensis, Abies canadensis, spruce, eastern hemlock, common hemlock, hemlock (oil), spruce (oil), fir needle (oil).

GENERAL DESCRIPTION: A large evergreen tree up to 50 metres tall, with slender horizontal branches, finely toothed leaves and smallish brown cones, which yields a natural exudation from its bark.

DISTRIBUTION: Native to the west coast of the USA. The oil is produced in Vermont, New York, New Hampshire, Virginia and Wisconsin.

OTHER SPECIES: Numerous cultivars of this species exist; often the oil is produced from a mixture of different types. Similar oils, also called simply ‘spruce oil’ are produced from the black spruce (Picea nigra or mariana), the Norway spruce (P. abies) and the white or Canadian spruce (P. glauca). The essential oil from the western hemlock (Tsuga heterophylla), contains quite different constituents. It is also closely related to the Douglas fir (Pseudotsuga taxifolia), which is also used to produce an essential oil and a balsam.

HERBAL/FOLK TRADITION: The bark of the hemlock spruce (which contains tannins and resin as well as volatile oil) is current in the British Herbal Pharmacopoeia indicated for diarrhoea, cystitis, mucous colitis, leucorrhoea, uterine prolapse, pharyngitis, stomatitis and gingivitis. An extract of the bark is also used in the tanning industry.

GENERAL DESCRIPTION: A deciduous tree up to 15 metres high with a purplish-grey bark, leaves arranged into five three-lobed sections, and white flowers. The styrax is a pathological secretion produced by pounding the bark, which induces the sapwood to produce a liquid from beneath the bark. It hardens to form a semi-solid greenish-brown mass with a sweet balsamic odour.

DISTRIBUTION: Native to Asia Minor. It forms forests around Bodrum, Milas, Mugla and Marmaris in Turkey.

OTHER SPECIES: Very similar to the American styrax (L. styraciflua) or red gum, which produces a natural exudation slightly darker and harder than the Levant type. There are also many other types of styrax; Styrax officinale produced the styrax of ancient civilizations. NB: Styrax benzoin is the botanical name for benzoin, with which it shares similar qualities.

HERBAL/FOLK TRADITION: In China it is used for coughs, colds, epilepsy and skin problems, including cuts, wounds and scabies. In the West it has been recommended as a remedy for catarrh, diphtheria, gonorrhoea, leucorrhoea, ringworm, etc. A syrup made from the bark of the American styrax is used for diarrhoea and dysentery in the western USA.

ACTIONS: Anti-inflammatory, antimicrobial, antiseptic, antitussive, bactericidal, balsamic, expectorant, nervine, stimulant.
