Detergents: From 1 Different Sources

Substances which clean the skin surface. This means that, strictly speaking, any soap, or soap-like substance used in washing, is a detergent. At the present day, however, the term is largely used for the synthetic detergents which are now used on such a large scale. These are prepared by the cracking and oxidation of high-petroleum waxes with sulphuric acid. The commoner ones in commercial preparations are aryl alkyl sulphate or sulphonate and secondary alkyl sulphate.

In view of their widespread use, such detergents appear to cause relatively little trouble with the skin, but more trouble has been reported with the so-called ‘biological’ detergents – named because they contain an ENZYME which destroys protein. As a result they are claimed to remove proteins (stains such as blood, chocolate, milk or gravy) which are relatively di?cult for ordinary detergents to remove. Unfortunately these ‘biological’ detergents may cause dermatitis. In addition, they have been reported to cause asthma in those using them, and even more so in workers manufacturing them.

Eczema

The most common skin disease; recognised by minute blisters (vesicles) which fill with colourless fluid and burst leaving the skin cracked, scaly and weepy with possible bleeding. Successful treatment depends upon recognising the type and distribution. Partly a metabolic imbalance.

Atopic eczema. Allergic eczema. May run in families together with hay fever, asthma or inflamed nasal membrane. May appear anywhere but prefers elbows, knees (flexures), ankles or face. Often seen in infants. May return again and again throughout adult life. Scratching exacerbates.

As regards babies, some paediatricians believe breast-feeding to be protective. A stronger case follows investigation into pollutants from the atmosphere or as additives in food. Industrial chemicals find their way into breast milk that may not be easily excreted but stored in fat.

Cow’s milk is particularly suspect because of exposure of the animal to herbicides and pesticides. For this reason, goat’s milk has met with some success in treatment of this condition, as has Soya milk. Now known that food plays an important part in effective treatment. Chief allergy-stimulators: dairy produce, eggs, cow’s milk. Each individual case must identify those foods that are responsible.

Seborrhoeic eczema leads to scaling of the scalp and redness of the ears, eyebrows, side of the nose and possibly armpits and groin.

Stasis eczema (or varicose eczema) may arise from varicose vein problems, usually limited to the lower third of the leg.

Discoid eczema has coin-shaped patches preferring extensor surfaces of arms and legs.

Contact eczema may be caused by washing-up detergents, etc. See: CONTACT DERMATITIS.

While emotional or psychic disturbance may worsen, eczema is seldom a psychosomatic disorder arising from stressful situations. Contact with water may worsen. Hairdressers and those allergic to dyes may require patch tests.

Eczema patients, especially atopic, have a metabolic deficiency of linoleic acid (a dietary fatty acid) to y-linolenic acid, which is found in Evening Primrose oil. Eczema may develop in bottle-fed babies due to absence of GLA (gamma-linolenic acid) in commercial powdered milk. GLA is present in Evening Primrose.

A cross-over trial in 99 patients (adults and children) by Bristol (England) dermatologists found Evening Primrose oil (Efamol capsules) produced an overall 43 per cent improvement in eczema severity: doses – 4 to 6 capsules twice daily (adults); 2 capsules twice daily (children). Lower doses were not effective.

Indicated: soothing softening herbal lotions, ointments or creams: Marshmallow, Chickweed, Comfrey, Witch Hazel, Aloe Vera gel, Jojoba oil, Evening Primrose oil. For seborrhoeic eczema: Bran Bath or Bran Wash, twice weekly, soapless, followed by Rosemary shampoo. Vitamin E lotion or cream.

Note: A study carried out at the University of Manchester, England, found that children with eczema had significantly low levels of serum zinc than control-cases. (British Journal of Dermatology, 1984, 111, 597)

Evening Primrose oil. For Omega 6 fatty acids.

Diet. Gluten-free. Oily fish: see entry. Avoid cow’s milk, wheat products.

Supplements. Daily. Vitamins: A (7500iu). C (500mg). E (400iu). Bioflavonoids (500mg). Zinc (15mg). Betaine hydrochloride.

Note: The disorder may be due to a deficiency of essential fatty acids (EFAs) brought about by a deficiency of zinc which is necessary for EFA metabolism.

Chinese herbs. A study has shown herbal treatment to be far superior to placebo in clinical trials. British children with (dry) atopic eczema responded favourably to treatment which included the following herbs known as Formula PSE101.

Ledebouriella sesloides, Potentilla chinesis, Anebia clematidis, Rehmannia glutinosa, Peonia lactiflora, Lophatherum gracile, Dictamnus dasycarpus, Tribulus terrestris, Glycyrrhiza uralensis, Schizonepta tenuifolia. Non-toxicity confirms their safety. (Sheeham M et al. “A controlled trial of traditional Chinese medicinal plants in widespread non-exudative atopic dermatitis”, British Journal of Dermatology, 126: 179-184 1992)

When 10 Chinese herbs were analysed by a team at the Great Ormond Street Hospital, London, it was revealed that no single active ingredient or herb was responsible for success. “It was a combination of all 10 herbs that gave the medicine its healing properties.” This is an example of the synergistic effect of combined plant remedies and supports the herbalist’s belief in use of the whole plant. ... eczema

Dermatitis

Inflammation of the skin, sometimes due to an allergy. Dermatitis is the same as eczema, and the terms can be used interchangeably.

Seborrhoeic dermatitis is a red, scaly, itchy rash that develops on the face, scalp, chest, and back. The rash often develops during times of stress and is probably caused by an excess growth of yeast on the skin. Corticosteroid drugs and/or drugs that kill microorganisms may help. Contact dermatitis results from a reaction to some substance that comes

in contact with the skin. Common causes are detergents, nickel, certain plants, and cosmetics. It may be treated with topical corticosteroids. A patch test (see skin tests) may be done to identify the cause. Photodermatitis occurs in people whose skin is abnormally sensitive to light. A cluster of spots or blisters occurs on any part of the body exposed to the sun (see photosensitivity). dermatitis artefacta Any self-induced skin condition. It may range from a mild scratch to extensive mutilation. dermatitis herpetiformis A chronic skin disease in which clusters of tiny, red, intensely itchy blisters occur in a symmetrical pattern, most commonly on the back, elbows, knees, buttocks, and scalp. It usually develops in adult life and is believed to be related to coeliac disease. dermatology The branch of medicine concerned with the skin and its disorders. dermatome An area of skin supplied with nerves by a pair of spinal nerve roots from the cervical (C2–C8), thoraci.

(T1–T12), lumbar (L1–L5), and sacral (S1–S5) regions.

The entire body surface is an interlocking pattern of dermatomes, which is similar from one person to another.

Abnormal sensation in a dermatome signifies damage to a particular nerve root, commonly due to a disc prolapse.... dermatitis

Chapped Hands

Chapped hands occur in cold weather, when reduced sweat and sebaceous activity leads to decreased natural protection of the skin. Prolonged immersion in soapy water, followed by exposure to cold air, results in cracking of the skin.

Prevention consists of minimising exposure to detergents and soapy water, and wearing rubber gloves for all routine household duties.... chapped hands

Skin, Diseases Of

They may be local to the SKIN, or a manifestation of systemic disorders – inherited or acquired. Some major types are described below.

Others appear under their appropriate alphabetical headings: ACNE; ALBINISM; ALOPECIA; ALOPECIA AREATA; APHTHOUS ULCER; BASAL CELL CARCINOMA; BOILS (FURUNCULOSIS); BOWEN’S DISEASE; CALLOSITIES; CANDIDA; CHEILOSIS; CHEIRAPOMPHOLYX; DANDRUFF; DERMATOFIBROMA; DERMATOMYOSITIS; DERMATOPHYTES; DERMOGRAPHISM; ECTHYMA; ERYSIPELAS; ERYTHEMA; ERYTHRASMA; ERYTHRODERMA; ESCHAR; EXANTHEM; FUNGAL AND YEAST INFECTIONS; HAND, FOOT AND MOUTH DISEASE; HERPES GENITALIS; HERPES SIMPLEX; HERPES ZOSTER; IMPETIGO; INTERTRIGO; KELOID; KERATOSIS; LARVA MIGRANS; LICHEN; LUPUS; MADURA FOOT; MELANOMA; MILIARIA; MOLLUSCUM CONTAGIOSUM; MOLE; MYCOSIS FUNGOIDES; NAEVUS; ORF; PEDICULOSIS; PEMPHIGUS; PHOTOCHEMOTHERAPY; PHOTODERMATOSES; PITYRIASIS; PORPHYRIAS; PRURITUS; PSORIASIS; RINGWORM; ROSACEA; SARCOIDOSIS; SCABIES; SCLERODERMA; URTICARIA; VITILIGO; WARTS; XANTHOMATA.

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

Xeroderma

The term means dry skin. Normal skin may become dry when exposed to very low ambient humidity and is then vulnerable to irritation by soaps, detergents and other chemicals which cause ‘chapping’. Dryness of the skin may also be a feature of skin disease, especially atopic eczema (see ATOPY; DERMATITIS). Genetically determined xeroderma is called ICHTHYOSIS.... xeroderma

Dentifrice

A paste, powder, or gel used with a toothbrush to clean the teeth. It contains a mild abrasive, detergents, binding and moistening agents, thickening agents, colourings, flavourings, and usually fluoride.... dentifrice

Barrier Cream

a preparation used to protect the skin against water-soluble irritants (e.g. detergents, breakdown products of urine). Usually applied in the form of a cream or ointment and often containing a silicone (such as *dimeticone), barrier creams are useful in the alleviation of various skin disorders, including napkin rash and pressure sores.... barrier cream

Detergent

n. a synthetic cleansing agent that removes all impurities from a surface by reacting with grease and suspended particles, including bacteria and other microorganisms. Detergents are used for cleansing or as *antiseptics and *disinfectants.... detergent

Nappy Rash

An inflammatory skin disorder around the anus and genitals caused by urine reacting with faecal bacteria to produce ammonia. By nature it is a chemical ‘burn’ and is aggravated by monilia, a wet nappy, or detergents used to wash the nappy.

Causes: nappies sealed in plastic pants for hours on end. Eggs.

Seborrhoea is a common type.

Treatment. After soiling, the nappy area should be washed in warm water and powdered with cornflour (cornstarch); this may be used as a substitute for talcum powder for reducing friction. Nappy rash is rare in Greece where it is a mother’s habit to clean a baby’s soiled bottom with a stream of warm water from a mixer tap, holding the infant over the left arm in the washbasin, and washing with the right hand. Topical. Emollient herbal creams: Comfrey, Marshmallow, Chickweed, Slippery Elm, Aloe Vera, Marigold (Calendula). Evening Primrose oil. Zinc and Castor oil ointment. A paste made from Slippery Elm and teaspoon Vitamin E oil. Fresh juice of Plantain or Comfrey.

Tea Tree oil: 10 drops in glass warm water. Saturate handkerchief or sterile dressing and apply.

Diet. Slippery Elm gruel. Avoid eggs. ... nappy rash

Anise, Star

Illicium verum

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. In the East generally, it is used as a remedy for colic and rheumatism, and often chewed after meals to sweeten the breath and promote digestion. A common oriental domestic spice.

Balsam, Canadian

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

Balsam, Copaiba

Copaifera officinalis

FAMILY: Fabaceae (Leguminosae)

SYNONYMS: Copahu balsam, copaiba, copaiva, Jesuit’s balsam, Maracaibo balsam, para balsam.

GENERAL DESCRIPTION: Wild-growing tropical tree up to 18 metres high, with thick foliage and many branches. The natural oleoresin occurs as a physiological product from various Copaifera species. Not a ‘true’ balsam.

DISTRIBUTION: Native to north east and central South America. Mainly produced in Brazil; also Venezuela, Guyana, Surinam and Colombia.

OTHER SPECIES: Several Copaifera speices yield an oleoresin: the Venezuelan type ‘Maracaibo balsam’ has a low oil content, the Brazilian type ‘para balsam’ has a high oil content. See also Botanical Classification section.

HERBAL/FOLK TRADITION: Used for centuries in Europe in the treatment of chronic cystitis and bronchitis; also for treating piles, chronic diarrhoea and intestinal problems.

ACTIONS: Batericidal, balsamic, disinfectant, diuretic, expectorant, stimulant.

EXTRACTION: 1. The crude balsam is collected by drilling holes into the tree trunks; it is one of the most plentiful naturally occurring perfume materials. 2. An essential oil is obtained by dry distillation from the crude balsam. It is mainly the ‘para balsams’ with a high oil content (60–80 per cent), which are used for distillation.

CHARACTERISTICS: 1. The crude balsam is a viscous, yellowy-brown or greenish-grey liquid which hardens upon exposure to air with a mild, woody, slightly spicy odour. It blends well with styrax, amyris, lavandin, cedarwood, lavender, oakmoss, woods and spices. 2. The oil is a pale yellow or greenish mobile liquid with a mild, sweet, balsamic-peppery odour. It blends well with cananga, ylang ylang, vanilla, jasmine, violet and other florals.

PRINCIPAL CONSTITUENTS: Mainly caryophyllene.

SAFETY DATA: Relatively non-toxic, non-irritant, possible sensitization. Large doses cause vomiting and diarrhoea.

AROMATHERAPY/HOME: USE:

Bay, West Indian

Pimenta racemosa

FAMILY: Myrtaceae

SYNONYMS: Myrcia acris, Pimenta acris, myrcia, bay, bay rum tree, wild cinnamon, bayberry, bay leaf (oil).

GENERAL DESCRIPTION: A wild-growing tropical evergreen tree up to 8 metres high, with large leathery leaves and aromatic fruits.

DISTRIBUTION: Native to the West Indies, particularly Dominica where the essential oil is produced.

OTHER SPECIES: There are several other varieties, for example the anise-scented and lemon-scented bay, the oils of which have a totally different chemical composition. Not to be confused with bay laurel, the common household spice, nor with the North American bayberry or wax myrtle (Myrcia cerifera) well known for its wax yielding berries.

HERBAL/FOLK TRADITION: The West Indian bay tree is often grown in groves together with the allspice or pimento bush, then the fruits of both are dried and powdered for the preparation of the household allspice. The so-called bay rum tree also provides the basic ingredient for the famous old hair tonic, which is made from the leaves by being distilled in rum. ‘A hair application with both fragrant and tonic virtues … useful for those who suffer from greasy hair and need a spirit-based, scalp-stimulating lotion to help them to control their locks!’9

ACTIONS: Analgesic, anticonvulsant, antineuralgic, antirheumatic, antiseptic, astringent, expectorant, stimulant, tonic (for hair).

EXTRACTION: Essential oil by water or steam distillation from the leaves. An oleoresin is also produced in small quantities.

CHARACTERISTICS: A dark yellow mobile liquid with a fresh-spicy top note and a sweet-balsamic undertone. It blends well with lavander, lavandin, rosemary, geranium, ylang ylang, citrus and spice oils.

PRINCIPAL CONSTITUENTS: Eugenol (up to 56 per cent), myrcene, chavicol and, in lesser amounts, methyl eugenol, linalol, limonene, among others.

SAFETY DATA: Moderately toxic due to high eugenol content; also a mucous membrane irritant – use in moderation only. Unlike bay laurel, however, it does not appear to cause dermal irritation or sensitization.

AROMATHERAPY/HOME: USE

Cajeput

Melaleuca cajeputi

FAMILY: Myrtaceae

SYNONYMS: M. minor, cajuput, white tea tree, white wood, swamp tea tree, punk tree, paperbark tree.

GENERAL DESCRIPTION: A tall evergreen tree up to 30 metres high, with thick pointed leaves and white flowers. The flexible trunk has a whitish spongy bark which flakes off easily. In Malaysia it is called ‘caju-puti’, meaning ‘white wood’, due to the colour of the timber.

DISTRIBUTION: It grows wild in Malaysia, Indonesia, the Philippines, Vietnam, Java, Australia and south eastern Asia.

OTHER SPECIES: Several other varieties of Melaleuca are used to produce cajeput oil, such as M. quinquenervia – see Botanical Classification section. Closely related to other members of the Melaleuca group, notably eucalyptus, clove, niaouli and tea tree.

HERBAL/FOLK TRADITION: Held in high regard in the East, it is used locally for colds, headaches, throat infections, toothache, sore and aching muscles, fever (cholera), rheumatism and various skin diseases. Only the oil is used in the Western herbal tradition, known for producing a sensation of warmth and quickening the pulse. It is used for chronic laryngitis and bronchitis, cystitis, rheumatism and to expel roundworm.

ACTIONS: Mildly analgesic, antimicrobial, antineuralgic, antispasmodic, antiseptic (pulmonary, urinary, intestinal), anthelmintic, diaphoretic, carminative, expectorant, febrifuge, insecticide, sudorific, tonic.

EXTRACTION: Essential oil by steam distillation from the fresh leaves and twigs.

CHARACTERISTICS: A pale yellowy-green, mobile liquid (the green tinge derives from traces of copper found in the tree), with a penetrating, camphoraceous-medicinal odour. Compared with eucalyptus oil, it has a slightly milder fruity body note.

PRINCIPAL CONSTITUENTS: Cineol (14–65 per cent depending on source), terpineol, terpinyl acetate, pinene, nerolidol and other traces.

SAFETY DATA: Non-toxic, non-sensitizing, may irritate the skin in high concentration.

AROMATHERAPY/HOME: USE

Skin Care: Insect bites, oily skin, spots.

Circulation Muscles And Joints: Arthritis, muscular aches and pains, rheumatism.

Cananga

Cananga odorata

FAMILY: Annonaceae

SYNONYM: C. odoratum var. macrophylla.

GENERAL DESCRIPTION: A tall tropical tree, up to 30 metres high, which flowers all year round. It bears large, fragrant, tender yellow flowers which are virtually identical to those of the ylang ylang.

DISTRIBUTION: Native to tropical Asia: Java, Malaysia, the Philippines, the Moluccas.

OTHER SPECIES: Very closely related to the tree which produces ylang ylang oil, C. odorata var. genuina. Cananga is considered an inferior product in perfumery work; being grown in different regions the oil has a different quality, heavier and less delicate than ylang ylang. However, cananga is truly a ‘complete’ oil whereas ylang ylang is made into several distillates.

HERBAL/FOLK TRADITION: Used locally for infectious illnesses, for example malaria. The beautiful flowers are also used for decorative purposes at festivals.

ACTIONS: Antiseptic, antidepressant, aphrodisiac, hypotensive, nervine, sedative, tonic.

Camphor

Cinnamomum camphora

FAMILY: Lauraceae

SYNONYMS: Laurus camphora, true camphor, hon-sho, laurel camphor, gum camphor, Japanese camphor, Formosa camphor.

GENERAL DESCRIPTION: A tall, handsome, evergreen tree, up to 30 metres high, not unlike the linden. It has many branches bearing clusters of small white flowers followed by red berries. It produces a white crystalline substance, the crude camphor, from the wood of mature trees over fifty years old.

DISTRIBUTION: Native to Japan and Taiwan principally, also China; cultivated in India, Ceylon, Egypt, Madagascar, southern Europe and America.

OTHER SPECIES: There are many species of camphor: the ho-sho variety produces ho leaf and ho wood oil; the Chinese variety produces apopin oil; the Japan and Taiwan type, known as hon-sho or true camphor, produces two chemotypes: camphor-safrol (Japan) and camphor-linalol (Taiwan). All these are to be distinguished from the Borneo camphor or borneol which is of different botanical origin.

HERBAL/FOLK TRADITION: A long-standing traditional preventative of infectious disease; a lump of camphor would be worn around the neck as a protection. In addition it was used for nervous and respiratory diseases in general, and for heart failure! However, in its crude form it is very poisonous in large doses, and has been removed from the British Pharmacopoeia.

ACTIONS: Anti-inflammatory, antiseptic, antiviral, bactericidal, counter-irritant, diuretic, expectorant, stimulant, rubefacient, vermifuge.

EXTRACTION: Crude camphor is collected from the trees in crystalline form. The essential oil is produced by steam distillation from the wood, root stumps and branches and then rectified under vacuum and filter pressed to produce three fractions, known as white, brown and yellow camphor.

CHARACTERISTICS: White camphor is the lightest (lowest boiling) fraction, a colourless to pale yellow liquid with a sharp, pungent camphoraceous odour. Brown camphor is the middle fraction. Yellow camphor, a blue-green or yellowish liquid, is the heaviest.

PRINCIPAL CONSTITUENTS: 1 White camphor contains mainly cineol, with pinene, terpineol, menthol, thymol and no safrol. 2. Brown camphor contains up to 80 per cent safrol and some terpineol. 3. Yellow camphor contains mainly safrol, sesquiterpenes and sesquiterpene alcohols.

SAFETY DATA: Brown and yellow camphor (containing safrol) are toxic and carcinogenic and ‘should not be used in therapy, either internally or externally.’. White camphor does not contain safrol and is relatively non-toxic, non-sensitizing and non-irritant. It is, however, an enviromental hazard or marine pollutant.

AROMATHERAPY/HOME: USE White camphor may be used with care for:

Skin care: Acne, inflammation, oily conditions, spots; also for insect prevention (flies, moths, etc).

Circulation Muscles And Joints: Arthritis, muscular aches and pains, rheumatism, sprains, etc.

Respiratory System: Bronchitis, chills, coughs.

Immune System: Colds, fever, ’flu, infectious disease.

OTHER USES: White and brown camphor are used as the starting material for the isolation of many perfumery chemicals, for example safrol and cineol. White camphor is used as a solvent in the paint and lacquer industry, and for the production of celluloid. Fractions of white oil are used as fragrance and masking agents in detergents, soaps, disinfectants and household products.... camphor

Nutmeg

Myristica fragrans

FAMILY: Myristicaceae

SYNONYMS: M. officinalis, M. aromata, Nux moschata, myristica (oil), mace (husk), macis (oil).

GENERAL DESCRIPTION: An evergreen tree up to 20 metres high with a greyish-brown smooth bark, dense foliage and small dull-yellow flowers. ‘Mace’ is the name given to the bright red netlike aril or husk surrounding the nutmeg shell and seed, which is contained within the fleshy fruit.

DISTRIBUTION: Native to the Moluccas and nearby islands; cultivated in Indonesia, Sri Lanka and the West Indies, especially Grenada.

EXTRACTION: Essential oil by steam (or water) distillation from 1. the dried worm eaten nutmeg seed (the worms eat away all the starch and fat content); 2. the dried orangebrown aril or husk – mace; and 3. an oleoresin is also produced in small quantities by solvent extraction from mace. The oil is also distilled in the USA and Europe from the imported nutmegs.

OTHER SPECIES: Indonesia and Sri Lanka produce the so-called ‘East Indian’ nutmeg which is considered superior, while Grenada produces the ‘West Indian’ nutmeg – see also Botanical Classification.

HERBAL/FOLK TRADITION: Nutmeg and mace are widely used as domestic spices in the East and West. They have been used for centuries as a remedy mainly for digestive and kidney problems. In Malaysia they are used during pregnancy to strengthen and tone the uterine muscles. Grated nutmeg with lard is used for piles. A fixed oil of nutmeg is also used in soap and candle making.

Nutmeg is current in the British Herbal Pharmacopoeia indicated for flatulent dyspepsia, nausea, diarrhoea, dysentery, and topically for rheumatism.

ACTIONS: Analgesic, anti-emetic, antioxidant, antirheumatic, antiseptic, antispasmodic, aphrodisiac, carminative, digestive, emmenagogue, gastric secretory stimulant, larvicidal, orexigenic, prostaglandin inhibitor, stimulant, tonic.

CHARACTERISTICS: 1. A water-white or pale yellow mobile liquid with a sweet, warm-spicy odour and a terpeney top-note. 2. A water white or pale yellow mobile liquid with a sweet, warm-spicy scent. 3. An orange-brown viscous liquid with a fresh, spicy-warm, balsamic fragrance. It has good masking power.

They blend well with oakmoss, lavandin, bay leaf, Peru balsam, orange, geranium, clary sage, rosemary, lime, petitgrain, mandarin, coriander and other spice oils.

PRINCIPAL CONSTITUENTS: Mainly monoterpene hydrocarbons (88 per cent approx.): camphene, pinene, dipentene, sabinene, cymene, with lesser amounts of geraniol, borneol, linalol, terpineol, myristicin (4–8 per cent), safrol and elemincin, among others. Mace oil contains similar constituents but contains more myristicin.

SAFETY DATA: Both nutmeg and mace are generally non-toxic, non-irritant and non sensitizing. However, used in large doses they show signs of toxicity such as nausea, stupor and tachycardia, believed to be due to the myristicin content. ‘Large quantities are hallucinogenic and excitant to the motor cortex.’. On this basis nutmeg (especially the West Indian type) is probably safer to use than mace. Use in moderation, and with care in pregnancy.

AROMATHERAPY/HOME: USE

Circulation muscles and joints: Arthritis, gout, muscular aches and pains, poor circulation, rheumatism.

Digestive system: Flatulence, indigestion, nausea, sluggish digestion.

Immune system: Bacterial infection.

Orange, Sweet

Citrus sinensis

FAMILY: Rutaceae

SYNONYMS: C. aurantium var. dulcis, C. aurantium var. sinensis, China orange, Portugal orange.

GENERAL DESCRIPTION: An evergreen tree, smaller than the bitter variety, less hardy with fewer or no spines. The fruit has a sweet pulp and non-bitter membranes. Another distinguishing feature is the shape of the leaf stalk: the bitter orange is broader and in the shape of a heart.

DISTRIBUTION: Native to China; extensively cultivated especially in America (California and Florida) and round the Mediterranean (France, Spain, Italy). The expressed oil is mainly produced in Israel, Cyprus, Brazil and North America; the distilled oil mainly comes from the Mediterranean and North America.

OTHER SPECIES: There are numerous cultivated varieties of sweet orange, for example Jaffa, Navel and Valencia. There are also many other subspecies such as the Japanese orange (C. aurantium var. natsudaidai). See also bitter orange.

HERBAL/FOLK TRADITION: A very nutritious fruit, containing vitamins A, B and C. In Chinese medicine the dried sweet orange peel is used to treat coughs, colds, anorexia and malignant breast sores. Li Shih-chen says: ‘The fruits of all the different species and varieties of citrus are considered by the Chinese to be cooling. If eaten in excess they are thought to increase the “phlegm”, and this is probably not advantageous to the health. The sweet varieties increase bronchial secretion, and the sour promote expectoration. They all quench thirst, and are stomachic and carminative.’.

ACTIONS: Antidepressant, anti-inflammatory, antiseptic, bactericidal, carminative, choleretic, digestive, fungicidal, hypotensive, sedative (nervous), stimulant (digestive and lymphatic), stomachic, tonic.

EXTRACTION: 1. Essential oil by cold expression (hand or machine) of the fresh ripe or almost ripe outer peel. 2. Essential oil by steam distillation of the fresh ripe or almost ripe outer peel. An oil of inferior quality is also produced by distillation from the essences recovered as a byproduct of orange juice manufacture. Distilled sweet orange oil oxidizes very quickly, and anti-oxidant agents are often added at the place of production. (An oil from the flowers is also produced occasionally called neroli Portugal or neroli petalae; an oil from the leaves is also produced in small quantities.)

SYNONYM: 1. A yellowy-orange or dark orange mobile liquid with a sweet, fresh fruity scent, richer than the distilled oil. It blends well with lavender, neroli, lemon, clary sage, myrrh and spice oils such as nutmeg, cinnamon and clove.

2. A pale yellow or colourless mobile liquid with a sweet, light-fruity scent, but little tenacity.

PRINCIPAL CONSTITUENTS: Over 90 per cent monoterpenes, mainly limonene. The cold expressed oil also contains bergapten, auraptenol and acids.

SAFETY DATA: Generally non-toxic (although ingestion of large amounts of orange peel has been known to be fatal to children); non-irritant and non-sensitizing (although limonene has been found to cause dermatitis in a few individuals). Distilled orange oil is phototoxic: its use on the skin should be avoided if there is danger of exposure to direct sunlight. However, there is no evidence to show that expressed sweet orange oil is phototoxic although it too contains coumarins.

DISTRIBUTION: Native to Europe, southern Russia and western Asia. Now cultivated worldwide, especially in Europe and the USA. The oil is mainly produced in France, Holland, Hungary and the USA.

OTHER SPECIES: The so-called French tarragon or ‘sativa’, which is cultivated as a garden herb, is a smaller plant with a sharper flavour than the Russian type and is a sterile derivative of the wild species.

HERBAL/FOLK TRADITION: The leaf is commonly used as domestic herb, especially with chicken or fish, and to make tarragon vinegar. The name is thought to derive from an ancient use as an antidote to the bites of venomous creatures and ‘madde dogges’. It was favoured by the maharajahs of India who took it as a tisane, and in Persia it was used to induce appetite.

‘The leaves, which are chiefly used, are heating and drying, and good for those that have the flux, or any prenatural discharge.’. The leaf was also formerly used for digestive and menstrual irregularities, while the root was employed as a remedy for toothache.

Pine, Scotch

Pinus sylvestris

FAMILY: Pinaceae

SYNONYMS: Forest pine, Scots pine, Norway pine, pine needle (oil).

GENERAL DESCRIPTION: A tall evergreen tree, up to 40 metres high with a flat crown. It has a reddish-brown, deeply fissured bark, long stiff needles which grow in pairs, and pointed brown cones.

DISTRIBUTION: Native to Eurasia; cultivated in the eastern USA, Europe, Russia, the Baltic States and Scandinavia, especially Finland.

OTHER SPECIES: Like the fir tree, there are numerous species of pine which yield an essential oil from their heartwood as well as from their twigs and needles and are also used to produce turpentine. The oil from the needles of the Scotch pine is one of the most useful and safest therapeutically. Other species which produce pine needle oil include the eastern white pine (P. strobus) from the eastern USA and Canada, the dwarf pine (P. mugo var. pumilio) grown in central and southern Europe, and the black pine (P. nigra) from Austria and Yugoslavia.

Many varieties, such as the longleaf pine (Pinus palustris), are used to produce turpentine. In addition, the oil commonly known as Siberian pine needle oil is actually from the Siberian fir (Abies sibirica). See also dwarf pine and the Botanical Classification section.

HERBAL/FOLK TRADITION: The young macerated shoots are added to the bath for nervous exhaustion, circulatory disorders, slow, healing wounds, arthritis, rheumatism and skin disorders. It was used by the American Indians to prevent scurvy, and to stuff mattresses to repel lice and fleas.

As an inhalation it helps relieve bronchial catarrh, asthma, blocked sinuses, etc. The pine kernels are said to be excellent restoratives for consumptives, and after long illness.

ACTIONS: Antimicrobial, antineuralgic, antirheumatic, antiscorbutic, antiseptic (pulmonary, urinary, hepatic), antiviral, bactericidal, balsamic, cholagogue, choleretic, deodorant, diuretic, expectorant, hypertensive, insecticidal, restorative, rubefacient, stimulant (adrenal cortex, circulatory, nervous), vermifuge.

EXTRACTION: 1. Essential oil by dry distillation of the needles. 2. Gum turpentine is produced by steam distillation from the oleoresin: see entry on turpentine. (An inferior essential oil is also produced by dry distillation from the wood chippings, etc.)

DISTRIBUTION: Native to South America; cultivated mainly in the east and south east USA, also India, Hungary and the USSR.

OTHER SPECIES: The parent plant, C. ambrosioides, is also used to produce an essential oil with similar properties. There are many different members in the Chenopodium or Goosefoot family, such as Good King Henry (C. bonus-henricus), a European variety whose leaves were eaten like spinach. See also Botanical Classification section.

The so-called ‘Russian wormseed oil’ or wormseed Levant (Artemisia cina) is quite different from the American type, although it is also used as an anthelmintic and is extremely toxic, containing mainly cineol.

HERBAL/FOLK TRADITION: ‘Used for many years by the local Indians as an effective anthelmintic ... several Indian tribes of the eastern part of the United States use the whole of the herb decocted to help ease painful menstruation and other female complaints.’. Apart from being used to expel roundworm, hookworm and dwarf tapeworm, the herb has also been employed for asthma, catarrh and other chest complaints, and to treat nervous disease. In China it is used to treat articular rheumatism. Causes dizziness and vomiting in concentration.

ACTIONS: Anthelmintic, antirheumatic, antispasmodic, expectorant, hypotensive.

EXTRACTION: Essential oil by steam distillation from the whole herb, especially the fruit or seeds.

SYNONYMS: Clary, clary wort, muscatel sage, clear eye, see bright, common clary, clarry, eye bright.

GENERAL DESCRIPTION: Stout biennial or perennial herb up to 1 metre high with large, hairy leaves, green with a hint of purple, and small blue flowers.

DISTRIBUTION: Native to southern Europe; cultivated worldwide especially in the Mediterranean region, Russia, the USA, England, Morocco and central Europe. The French, Moroccan and English clary are considered of superior quality for perfumery work.

OTHER SPECIES: Closely related to the garden sage (S. officinalis) and the Spanish sage (S. lavendulaefolia), which are both used to produce essential oils. Other types of sage include meadow clary (S. pratensis) and vervain sage (S. verbenaca). Clary sage should not be confused with the common wayside herb eyebright (Euphrasia).

HERBAL/FOLK TRADITION: This herb, highly esteemed in the Middle Ages, has now largely fallen out of use. It was used for digestive disorders, kidney disease, uterine and menstrual complaints, for cleansing ulcers and as a general nerve tonic. The mucilage from the seeds was used for treating tumours and for removing dust particles from the eyes.

Like garden sage, it cools inflammation and is especially useful for throat and respiratory infections.

FAMILY: Santalaceae

SYNONYMS: White sandalwood, yellow sandalwood, East Indian sandalwood, sandalwood Mysore, sanders-wood, santal (oil), white saunders (oil), yellow saunders (oil).

GENERAL DESCRIPTION: A small, evergreen, parasitic tree up to 9 metres high with brown-grey trunk and many smooth, slender branches. It has leathery leaves and small pinky-purple flowers. The tree must be over thirty years old before it is ready for the production of sandalwood oil.

DISTRIBUTION: Native to tropical Asia, especially India, Sri Lanka, Malaysia, Indonesia and Taiwan. India is the main essential oil producer; the region of Mysore exports the highest quality oil, although some oil is distilled in Europe and the USA.

OTHER SPECIES: The Australian sandalwood (S. spicatum or Eucarya spicata) produces a very similar oil, but with a dry-bitter top note. The so-called West Indian sandalwood or amyris (Amyris balsamifera) is a poor substitute and bears no botanical relation to the East Indian sandalwood.

HERBAL/FOLK TRADITION: One of the oldest known perfume materials, with at least 4000 years of uninterrupted use. It is used as a traditional incense, as a cosmetic, perfume and embalming material all over the East. It is also a popular building material, especially for temples.

In Chinese medicine it is used to treat stomach ache, vomiting, gonorrhoea, choleraic difficulties and skin complaints. In the Ayurvedic tradition it is used mainly for urinary and respiratory infections, for acute and chronic diarrhoea. In India it is often combined with rose in the famous scent aytar.

ACTIONS: Antidepressant, antiphlogistic, antiseptic (urinary and pulmonary), antispasmodic, aphrodisiac, astringent, bactericidal, carminative; cicatrisant, diuretic, expectorant, fungicidal, insecticidal, sedative, tonic.

EXTRACTION: Essential oil by water or steam distillation from the roots and heartwood, powdered and dried.

Employed as a flavour ingredient in most major food categories, including soft and alcoholic drinks.... sandalwood

Ylang Ylang

Cananga odorata var. genuina

FAMILY: Annonaceae

SYNONYMS: Unona odorantissimum, flower of flowers.

GENERAL DESCRIPTION: A tall tropical tree up to 20 metres high with large, tender, fragrant flowers, which can be pink, mauve or yellow. The yellow flowers are considered best for the extraction of essential oil.

DISTRIBUTION: Native to tropical Asia, especially Indonesia and the Philippines. Major oil producers are Madagascar, Reunion and the Comoro Islands.

OTHER SPECIES: Very closely related to cananga (C. odoratum var. macrophylla), although the oil produced from the ylang ylang is considered of superior quality for perfumery work, having a more refined quality.

HERBAL/FOLK TRADITION: In Indonesia, the flowers are spread on the beds of newly married couples on their wedding night. In the Molucca Islands, an ointment is made from ylang ylang and cucuma flowers in a coconut oil base for cosmetic and hair care, skin diseases, to prevent fever (including malaria) and fight infections.

In the Victorian age, the oil was used in the popular hair treatment Macassar oil, due to its stimulating effect on the scalp, encouraging hair growth. The oil was also used to soothe insect bites, and is thought to have a regulating effect on cardiac and respiratory rhythm.

ACTIONS: Aphrodisiac, antidepressant, anti infectious, antiseborrhoeic, antiseptic, euphoric, hypotensive, nervine, regulator, sedative (nervous), stimulant (circulatory), tonic.

EXTRACTION: Essential oil by water or steam distillation from the freshly picked flowers. The first distillate (about 40 per cent) is called ylang ylang extra, which is the top grade. There are then three further successive distillates, called Grades 1, 2 and 3. A ‘complete’ oil is also produced which represents the total or ‘unfractionated’ oil, but this is sometimes constructed by blending ylang ylang 1 and 2 together, which are the two least popular grades. (An absolute and concrete are also produced by solvent extraction for their long-lasting floral-balsamic effect.)

CHARACTERISTICS: Ylang ylang extra is a pale yellow, oily liquid with an intensely sweet, soft, floral-balsamic, slightly spicy scent – a good oil has a creamy rich topnote. A very intriguing perfume oil in its own right, it also blends well with rosewood, jasmine, vetiver, opopanax, bergamot, mimosa, cassie, Peru balsam, rose, tuberose, costus and others. It is an excellent fixative. The other grades lack the depth and richness of the ylang ylang extra.

PRINCIPAL CONSTITUENTS: Methyl benzoate, methyl salicylate, methyl paracretol, benzyl acetate, eugenol, geraniol, linalol and terpenes: pinene, cadinene, among others.

SAFETY DATA: Non-toxic, non-irritant, a few cases of sensitization reported. Use in moderation, since its heady scent can cause headaches or nausea.

AROMATHERAPY/HOME: USE

Skin care: Acne, hair growth, hair rinse, insect bites, irritated and oily skin, general skin care.

Circulation muscles and joints: High blood pressure, hyperpnoea (abnormally fast breathing), tachycardia, palpitations.

Nervous system: Depression, frigidity, impotence, insomnia, nervous tension and stress-related disorders – ‘The writer, working with odorous materials for more than twenty years, long ago noticed that ... ylang ylang soothes and inhibits anger born of frustration.’.

OTHER USES: Extensively used as a fragrance component and fixative in soaps, cosmetics and perfumes, especially oriental and floral types; ylang ylang extra tends to be used in high-class perfumes, ylang ylang 3 in soaps, detergents, etc. Used as a flavour ingredient, mainly in alcoholic and soft drinks, fruit flavours and desserts.... ylang ylang
