Wart

A common, contagious, harmless growth that occurs on the skin or mucous membranes. Only the topmost layer of skin is affected. An overgrowth of cells in this layer causes a visible lump to develop. Warts are caused by the human papillomavirus, of which at least 30 different types are known. These cause different types of warts at various sites, such as on the hands or genitals.

Flat warts are flesh-coloured, sometimes itchy lumps with flat tops that occur mainly on the wrists, backs of hands, and face. About 50 per cent of warts disappear in 6–12 months without treatment. However, genital warts should be treated promptly. Common, flat, and plantar warts can sometimes be destroyed using a wart-removing liquid or special plaster. Several treatments may be necessary, and sometimes the wart returns. Warts are commonly treated by cryosurgery.

wart, plantar A hard, horny, and roughsurfaced area on the sole of the foot caused by a virus called a papillomavirus. Plantar warts, also known as verrucas, may occur singly or in clusters. The wart is flattened and forced into the skin and may cause discomfort or pain when walking. Infection is usually acquired from contaminated floors in swimming pools and communal showers.

Many plantar warts disappear without treatment, but some persist for years or recur. They can be removed by cryosurgery or by applying plasters or gel containing salicylic acid.... wart

Laser

Laser stands for Light Ampli?cation by Stimulated Emission of Radiation. The light produced by a laser is of a single wavelength and all the waves are in phase with each other, allowing a very high level of energy to be projected as a parallel beam or focused on to a small spot.

Various gases, liquids and solids will emit light when they are suitably stimulated. A gassed laser is pumped by the ionising e?ect of a high-voltage current. This is the same process as that used in a ?uorescent tube. Each type of laser has a di?erent e?ect on biological tissues and this is related to the wavelength of the light produced. The wavelength determines the degree of energy absorption by di?erent tissues, and because of this, di?erent lasers are needed for di?erent tasks. The argon laser produces light in the visible green wavelength which is selectively absorbed by HAEMOGLOBIN. It heats and coagulates (see COAGULATION) tissues so can be used to seal bleeding blood vessels and to selectively destroy pigmented lesions. The carbon-dioxide laser is the standard laser for cutting tissue: the infra-red beam it produces is strongly absorbed by water and so vaporises cells. Thus, by moving a ?nely focused beam across the tissue, it is possible to make an incision.

The two main uses of laser in surgery are the endoscopic (see ENDOSCOPE) photocoagulation of bleeding vessels, and the incision of tissue. Lasers have important applications in OPHTHALMOLOGY in the treatment of such disorders as detachment of the retina and the diabetic complications of proliferative retinopathy and of the cornea (see EYE, DISORDERS OF). The destruction of abnormal cells – a sign of pre-malignancy – in the CERVIX UTERI is done using lasers. The beams may also be used to remove scar tissue from the FALLOPIAN TUBES resulting from infection, thus unblocking the tubes and improving the chances of CONCEPTION. Lasers also have several important applications in DERMATOLOGY. They are used in the treatment of pigmented lesions such as LENTIGO, in the obliteration of port-wine stains, in the removal of small, benign tumours such as verrucas, and ?nally in the removal of tattoos.

Low-intensity laser beams promote tissue healing and reduce in?ammation, pain and swelling. Their e?ect is achieved by stimulating blood and lymph ?ow and by cutting the production of PROSTAGLANDINS, which provoke in?ammation and pain. The beams are used to treat ligament sprains, muscle tears and in?amed joints and tendons.

The three great advantages of lasers are their potency, their speed of action, and the ability to focus on an extremely small area. For these reasons they are widely used, and have allowed great advances to be made in microsurgery, and particularly in FIBREOPTIC ENDOSCOPY.... laser

Papova Viruses

These include the human papilloma viruses (HPV), of which nearly a hundred strains have been identi?ed. HPV cause verrucae (see WARTS) on skin and, less often, on the mucous membranes of mouth, larynx, genitalia and the cervix. Some strains may predispose to eventual cancer.... papova viruses

Podophyllum Hexandrum

Royle.

Synonym: P. emodi Wall. ex Hook. f. & Thoms.

Family: Berberidaceae.

Habitat: Inner ranges of the Himalayas, from Kashmir to Sikkim at 1,800-4,000 m.

English: Indian Podophyllum.

Ayurvedic: Giriparpata.

Folk: Bana-kakari (Punjab), Venivel (Gujarat), Patvel (Maharashtra). Paapraa, Paapri.

Action: Rhizomes and roots— antineoplastic. Strongly irritant to skin and mucous membranes. Used topically as an ointment for venereal warts, verrucae and similar conditions.

Key application: P. peltatum— externally, for removal of pointed condyloma (skin adjacent to the treated area should be protected). (German Commission E.) P hexandrum: Podophyllin (10-40%) for external application, 2-6 h weekly, for anogenital warts. (Indian Herbal Pharmacopoeia.) (Podophyllin is a mitotic poison.)

May Apple of North America is equated with Podophyllum peltatum Linn. The main lignin is podophyllo- toxin. Podophyllum hexandrum contains similar lignans with the exception of alpha-and beta-peltatins, which are reportedly absent; the concentration of podophyllotoxin is up to 4.3%. P. peltatum contains about 0.25% and the Taiwanese species P. pleianthum 0.1% podophyllotoxin.

(Podophyllotoxin is a valuable lig- nin, as it is used for the synthesis of chemically administered cytostat- ic etoposide and tenoposide.)... podophyllum hexandrum

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

Warts

Warts (verrucae) are small, solid outgrowths from the SKIN arising from the epidermis and caused by various subtypes of ‘human papilloma virus’. The causal viruses are ubiquitous and most people probably harbour them. Whether or not warts develop depends upon age, previous infection and natural resistance.

Common warts (verruca vulgaris) are seen mainly in children and young adults on the backs of the ?ngers and hands, and less often on the knees, face or scalp. They may be single or numerous and range from 1 mm to 10 mm or more in size. Untreated, they often resolve spontaneously after weeks or months. They may be occupationally contracted by butchers and meat-handlers.

Plane warts (verruca plana) are small, ?at-topped, yellowish papules seen mainly on the backs of the hands, wrists and face in young people. They may persist for years.

Digitate warts (verruca digitata) are ?nger- or thread-like warts up to 5 mm in length with a dark rough tip. They tend to grow on the eyelids or neck.

Plantar warts (verruca plantaris) occur on the soles of the feet, most commonly in older children, adolescents and young adults. Spread by walking barefoot in swimming pools, changing rooms, etc., these warts may appear as minor epidemics in institutions, such as schools. They are ?attened, yellow-white discrete lesions in the sole or heel, tender when squeezed. Multiple black points in the wart are thrombosed capillaries. Occasionally, aggregates of plantar warts form a mosaic-like plaque, especially in chronically warm, moist feet.

Genital warts are sexually transmitted. In the male they occur on the shaft of the PENIS and on the PREPUCE or around the anus. In women they occur around the entrance to the VAGINA and LABIA minora. Genital warts vary from 1–2 mm pink papules to ?orid, cauli?ower-like masses. Pregnancy facilitates their development.

Mucosal warts may develop on the mucous membranes of the mouth.

Laryngeal warts may be found in children whose mothers had genital warts (see above) at the time of delivery. Some subtypes of genital wart can infect the uterine cervix (see UTERUS), causing changes which may lead eventually to cancer.

Treatment CRYOTHERAPY – freezing with liquid nitrogen – is the principal weapon against all types of warts, but curettage (scraping out the wart with a CURETTE) and cauterisation (see ELECTROCAUTERY) or LASER therapy may be required for resistant warts. Genital warts may respond to local application of PODOPHYLLIN preparations. Sexual partners should be examined and treated if necessary. Finally, treatment of warts should not be more onerous or painful than the disease itself, since spontaneous resolution is so common.... warts

Foot

The foot has 2 vital functions: to support the weight of the body in standing or walking and to act as a lever to propel the body forwards.

The largest bone of the foot, the heelbone (see calcaneus), is jointed with the ankle bone (the talus). In front of the talus and calcaneus are the tarsal bones, which are jointed the 5 metatarsals. The phalanges are the bones of the toes; the big toe has 2 phalanges; all the other toes have 3.

Tendons passing around the ankle connect the muscles that act on the foot bones. The main blood vessels and nerves pass in front of and behind the inside of the ankle to supply the foot. The undersurface of the normal foot forms an arch supported by ligaments and muscles. Fascia (fibrous tissue) and fat form the sole of the foot, which is covered by a layer of tough skin.

Injuries to the foot commonly result in fracture of the metatarsals and phalanges. Congenital foot abnormalities are fairly common and include club-foot (see talipes), and claw-foot. A bunion is a common deformity in which a thickened bursa (fluid-filled pad) lies over the joint at the base of the big toe. Corns are small areas of thickened skin and are usually a result of tight-fitting shoes. Verrucas (see plantar warts) develop on the soles of the feet. Athlete’s foot is a fungal infection that mainly affects the skin in between the toes. Gout often affects the joint at the base of the big toe. An ingrowing toenail (see toenail, ingrowing) commonly occurs on the big toe and may result in inflammation and infection of the surrounding tissues (see paronychia). Foot-drop is the inability to raise the foot properly when walking and is the result of a nerve problem.... foot

Ravintsara

Cinnamomum camphora

FAMILY: Lauraceae

SYNONYMS: Cinnamomum camphora ct. 1,8-cineole.

GENERAL DESCRIPTION: Cinnamomum camphora is a tall evergreen tropical tree characteristic of the Laurel family that grows up to 20–30 metres tall. The foliage is bright green and the leaves have a glossy, waxy appearance bearing masses of small white flowers in spring. It produces clusters of shiny black berries and has a pale bark that is very rough and fissured vertically.

DISTRIBUTION: C. camphora is native to China, Japan, and Taiwan but has been introduced to many countries throughout the world including India, Australia and the USA, where in places such as Florida it is becoming increasingly invasive and a danger to the native flora. This species is not indigenous to Madagascar and was introduced onto the island during the middle of the nineteenth century. As the plant became accustomed to the Malagasy climate it became a distinct subspecies, which in time adapted so well to the new environment, naturalizing in the central-eastern regions, that it became a very sustainable species for producing an essential oil, now called ravintsara oil. However, since it is clear there are many different sub-varieties of C. camphora in various parts of the world, it is possible that there also existed another native aromatic tree already growing in Madagascar originally known as ravintsara by the local people. According to Georges M. Halpern in The Healing Trail: Essential Oils of Madagascar, an indigenous tree of this name had been part of the Malagasy culture for many centuries and its leaves were used as a traditional folk medicine.

OTHER SPECIES: The genus Cinnamomum has approximately 250 different species, many of which yield an essential oil on distillation. Amongst the most important are C. zeylanicum (cinnamon bark and leaf oils) and C. cassia (cassia oil). The single species C. camphora itself produces a wide range of essential oils including: camphor, ho wood and leaf oil, sassafras and ravintsara. All these essential oils, although derived from the same tropical tree or botanical species, differ in their chemical profile enormously depending on the country of origin as well as the part of the plant used to extract the oil: e.g. leaf or bark.

There are at least 6 different chemotypes of C. camphora essential oil due to this factor, including the camphor, linalool, 1,8-cineole, nerolidol, safrole and borneol types. For example, C. camphora, grown in Taiwan and Japan, is known as Ho oil, and has linalool as its major constituent, whereas in India and Sri Lanka the camphor type of C. camphora remains the most important. The variety of C. camphora cultivated in Madagascar contains high levels of 1,8-cineole and no camphor. In order to avoid any confusion, it has been suggested that Ravintsara should be labelled: ‘Cinnamomum camphora ct. 1,8-cineole.’

HERBAL/FOLK TRADITION: The term Cinnamomum is derived from the Greek root kinnamon or kinnamomon meaning ‘sweet wood’. The word ravint means leaf and sara means ‘good for you’ according to the Malagasy tradition, as the local people have long appreciated the therapeutic value of its leaves which were used in folk medicine to treat digestive complaints, headaches, colds and chest infections. It has also been used for culinary applications and employed as a herbal tea. The Malagasy people themselves believe that the original Ravintsara tree is an indigenous species: a ‘cousin’ of the well-known C. camphora species, which has since been introduced.

ACTIONS: Antibacterial, anticatarrhal, antifungal, anti-infectious, antimicrobial, antirheumatic, antiviral, decongestant, cicatrisant (wound healer), expectorant, immune and neurotonic.

EXTRACTION: Steam distilled from the leaves of the plant.

CHARACTERISTICS: Fresh, woody, slightly floral, balsamic, eucalyptus-like scent. It blends well with eucalyptus, rosemary, bay, frankincense, cardamon, pine, cypress, juniper and citrus oils.

PRINCIPAL CONSTITUENTS: Ravintsara is akin to Eucalyptus globulus oil (as both are particularly effective for respiratory infections) due to its high 1,8-cineole content ranging from 45–55 per cent. Other major constituents include monoterpenes (sabinene 15 per cent, alpha-pinene and beta-pinene), sesquiterpenes (beta-carophyllene), monoterpenic alcohols (alpha-terpineol 7 per cent and terpineol) and esters (terpenyl acetate).

NOTE: Ravintsara essential oil contain at least 45 per cent 1,8-cineole compared to approximately 5 per cent found in Ravensara aromatica oil.

SAFETY DATA: Ravintsara oil is generally very well tolerated by the majority of the population, although like eucalyptus, it can cause sensitization in some individuals and should be used in moderation.

AROMATHERAPY/HOME: USE

Skin care: Shingles, herpes, verrucas, warts and athletes foot.

Circulation muscles and joints: Aching muscles and joints.

Respiratory system: Coughs, colds, influenza and other respiratory ailments such as asthma, bronchitis, sinusitis, laryngitis, otitis, tonsillitis and whooping cough.

OTHER USES: Ravintsara oil is produced in a ‘pharmaceutical grade’ for the chemical and perfumery industry.... ravintsara

Santolina

Santolina chamaecyparissus

FAMILY: Asteraceae (Compositae)

SYNONYMS: Lavandula taemina, cotton lavender

GENERAL DESCRIPTION: An evergreen, woody shrub with whitish-grey foliage and small, bright yellow, ball-shaped flowers borne on long single stalks. The whole plant has a strong rather rank odour, a bit like chamomile.

DISTRIBUTION: Native to Italy, now common throughout the Mediterranean region. Much grown as a popular border herb.

OTHER SPECIES: There are several varieties such as S. fragrantissima. It is not related to true lavender (Lavandula angustifolia) despite the common name.

HERBAL/FOLK TRADITION: It was used as an antidote to all sorts of poison, and to expel worms; also ‘good against obstruction of the liver, the jaundice and to promote the menses’.. It was used to keep away moths from linen, to repel mosquitos, and as a remedy for insect bites, warts, scabs and verrucae. The Arabs are said to have used the juice for bathing the eyes.

ACTIONS: Antispasmodic, antitoxic, anthelmintic, insecticidal, stimulant, vermifuge.

EXTRACTION: Essential oil by steam distillation from the seeds.

CHARACTERISTICS: A pale yellow liquid with a strong, acrid, herbaceous odour.

PRINCIPAL CONSTITUENTS: Only one principal constituent: santolinenone.

SAFETY DATA: Oral toxin. ‘There is no safety data available ... likely to be dangerously toxic.’.

AROMATHERAPY/HOME: USE None.

OTHER USES: Little used in flavour or perfumery work due to toxicity.... santolina

Tea Tree

Melaleuca alternifolia

FAMILY: Myrtaceae

SYNONYMS: Narrow-leaved paperbark tea tree, ti-tree, ti-trol, melasol.

GENERAL DESCRIPTION: A small tree or shrub (smallest of the tea tree family), with needle-like leaves similar to cypress, with heads of sessile yellow or purplish flowers.

DISTRIBUTION: Native to Australia. Other varieties have been cultivated elsewhere, but M. alternifolia is not produced outside Australia, mainly in New South Wales.

OTHER SPECIES: Tea tree is a general name for members of the Melaleuca family which exists in many physiological forms including cajeput (M. cajeputi) and niaouli (M. viridiflora), and many others such as M. bracteata and M. linariifolia – see Botanical Classification section.

HERBAL/FOLK TRADITION: The name derives from its local usage as a type of herbal tea, prepared from the leaves. Our present knowledge of the properties and uses of tea tree is based on a very long history of use by the aboriginal people of Australia. It has been extensively researched recently by scientific methods with the following results: ‘1. This oil is unusual in that it is active against all three varieties of infectious organisms: bacteria, fungi and viruses. 2. It is a very powerful immuno-stimulant, so when the body is threatened by any of these organisms ti-tree increases its ability to respond.’ .

ACTIONS: Anti-infectious, anti-inflammatory, antiseptic, antiviral, bactericidal, balsamic, cicatrisant, diaphoretic, expectorant, fungicidal, immuno-stimulant, parasiticide, vulnerary.

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

CHARACTERISTICS: A pale yellowy-green or water-white mobile liquid with a warm, fresh, spicy-camphoraceous odour. It blends well with lavandin, lavender, clary sage, rosemary, oakmoss, pine, cananga, geranium, marjoram, and spice oils, especially clove and nutmeg.

PRINCIPAL CONSTITUENTS: Terpinene-4-ol (up to 30 per cent), cineol, pinene, terpinenes, cymene, sesquiterpenes, sesquiterpene alcohols, among others.

SAFETY DATA: Non-toxic, non-irritant, possible sensitization in some individuals.

Genito-urinary system: Thrush, vaginitis, cystitis, pruritis.

Immune system: Colds, fever, ’flu, infectious illnesses such as chickenpox.

OTHER USES: Employed in soaps, toothpastes, deodorants, disinfectants, gargles, germicides and, increasingly, in aftershaves and spicy colognes.... tea tree

Thuja

Thuja occidentalis

FAMILY: Cupressaceae

SYNONYMS: Swamp cedar, white cedar, northern white cedar, eastern white cedar, tree of life, American arborvitae, cedarleaf (oil).

GENERAL DESCRIPTION: A graceful pyramid-shaped coniferous tree up to 20 metres high with scale-like leaves and broadly-winged seeds, sometimes planted as hedging. The tree must be at least fifteen years old before it is ready to be used for essential oil production.

DISTRIBUTION: Native to north eastern North America; cultivated in France. The oil is produced mainly in Canada and the USA, similar oils are also produced in the East – see here.

OTHER SPECIES: There are many forms and cultivated varieties of this tree: the western red cedar or Washington cedar (T. plicata); the Chinese or Japanese cedar (T. orientalis or Biota orientalis); the North African variety (T. articulata) which yields a resin known as ‘sanderac’.

The hiba tree (Thujopsis dolobrata) is used to produce hiba wood oil and hiba leaf oil in Japan. Hiba wood oil, according to available data, is non-toxic, non-irritant and non-sensitizing (unlike the other thuja oils), and has excellent resistance to fungi and bacteria due to the ketonic substances found in the oil. It is used extensively in Japan as an industrial perfume.

HERBAL/FOLK TRADITION: Used as an incense by ancient civilizations for ritual purposes. A decoction of leaves has been used for coughs, fever, intestinal parasites, cystitis and venereal diseases. The ointment has been used for rheumatism, gout, warts, verrucae, psoriasis and other ailments.

The twigs are current in the British Herbal Pharmacopoeia, used specifically for bronchitis with cardiac weakness, and warts.

ACTIONS: Antirheumatic, astringent, diuretic, emmenagogue, expectorant, insect repellent, rubefacient, stimulant (nerve, uterus and heart muscles), tonic, vermifuge.

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

CHARACTERISTICS: A colourless to pale yellowy-green liquid with a sharp, fresh, camphoraceous odour.

PRINCIPAL CONSTITUENTS: Thujone (approx. 60 per cent), fenchone, camphor, sabinene and pinene, among others.

SAFETY DATA: Oral toxin – poisonous due to high thujone content. Abortifacient.

AROMATHERAPY/HOME: USE None. ‘Should not be used in aromatherapy either internally or externally.’.

OTHER USES: Used in pharmaceutical products such as disinfectants and sprays; also as a counter-irritant in analgesic ointments and liniments. A fragrance component in some toiletries and perfumes. Employed as a flavour ingredient in most major food categories (provided that the finished food is recognized thujone-free).... thuja
