Key application: Bark—in nonspecific acute diarrhoea and in topical therapy for mild inflammation of the oral-pharyngeal mucosa; externally in mild, superficial inflammation of the skin. (German Commission E.) The seed has been included among unapproved herbs by German Commission E, as the blood sugar-lowering effect could not be established by several researchers. Claimed applications mentioned in German Commission E monograph: in diabetes, also in combination preparations for atonic and spastic constipation, diseases of the pancreas, gastric and pancreatic complaints.

The Ayurvedic Pharmacopoeia of India recommends the bark in acute diarrhoea and haemorrhagic diseases; the seed in hyperglycaemia and polyuria.

The aqueous alcoholic extract of the bark contains bergenin, gallic acid and ethyl gallate.

The fruit contains anthocyanins and yielded citric, malic and gallic acids. Gallic acid and tannins account for as- tringency of the fruit. Malic acid is the major acid (0.59%) of the weight of fruit; a small quantity of oxalic acid is reported to be present. Glucose and fructose are principal sugars in the ripe fruit; surcose was not detected.

The seeds contain tannin (about 19%), ellagic acid, gallic acid (1-2%), beta-sitosterol, 0.05% essential oil; myricyl alcohol is present in the un- saponifiable matter.

The stem bark yielded friedelan-3- alpha-ol, kaempferol, quercetin, beta- sitosterol and its glycoside, kaempferol- 3-O-glucoside, gallic acid, friedelin and betulinic acid. It contained eugenin and epi-friedelanol. 10-12% tannins were reported.

The leaves contain aliphatic alcohols, sitosterols, betulinic acid and crategolic (maslinic) acid.

The flowers contain triterpenic acids—oleanolic acid and crategolic acid. The oleanolic acid is a strong protector against adriamycin-induced lipid peroxidation in liver and heart microsomes.

Phenols, including methylxantho- xylin and 2, 6-dihydroxy-4-methoxy- acetophene have been isolated from the plant (also from the seed).

Seeds in a dose of 10 mg/kg p.o. on normal and alloxanized rabbits exhibited hypoglycaemic activity up to 23 and 20% respectively. The chloroform fraction of seed extract exhibited potent anti-inflammatory action against both exudative and prolifer- ative and chronic phases of inflammation, besides exhibiting significant anti-arthritic, antipyretic and analgesic activities. Water extract exhibited antibacterial property against S. boydi and S. dysentrae in cases of dysentery and diarrhoea.

The bark extract is reported to have an effect on glycogenolysis and glyco- gen storage in animals.

Dosage: Stem bark—10-20 g for decoction; dried seed—3-6 g powder. (API, Vol. II.)... syzygium cuminii

OTHER SPECIES: Four other varieties of pimento are found in Venezuela, Guyana and the West Indies which are used locally as spices.

HERBAL/FOLK TRADITION: Used for flatulent indigestion and externally for neuralgic or rheumatic pain. Pimento water is used as a vehicle for medicines which ease dyspepsia and constipation since it helps prevent griping pains. It is used extensively as a domestic spice – allspice is so called because it tastes like a combination of cloves, juniper berries, cinnamon and pepper.

ACTIONS: Anaesthetic, analgesic, anti-oxidant, antiseptic, carminative, muscle relaxant, rubefacient, stimulant, tonic.

EXTRACTION: Essential oil by steam distillation from 1. the leaves, and 2. the fruit. The green unripe berries contain more oil than the ripe berries, but the largest percentage of oil is contained in the shell of the fruit. An oleoresin from the berries is also produced in small quantities.

Eucalyptus globulus var. globulus

FAMILY: Myrtaceae

SYNONYMS: Gum tree, southern blue gum, Tasmanian blue gum, fever tree, stringy bark.

GENERAL DESCRIPTION: A beautiful, tall, evergreen tree, up to 90 metres high. The young trees have bluish-green oval leaves while the mature trees develop long, narrow, yellowish leaves, creamy-white flowers and a smooth, pale grey bark often covered in a white powder.

DISTRIBUTION: Native to Tasmania and Australia. Mainly cultivated in Spain and Portugal, also Brazil, California, Russia and China. Very little of this oil now comes from its native countries.

OTHER SPECIES: There are over 700 different species of eucalyptus, of which at least 500 produce a type of essential oil. Many have been extracted simply for experimental purposes, and research is still being carried out with regard to the different constituents of each oil. In general, they can be divided into three categories. 1. The medicinal oils containing large amounts of cineol (or eucalyptol), such as the blue gum, but increasingly the blue malee (E. polybractea), the narrow-leaved peppermint (E. radiata var. australiana) and the gully gum (E. smithii). 2. The industrial oils containing mainly piperitone and phellandrene, such as the peppermint eucalyptus (E. piperita), grey peppermint (E. radiata var. phellandra) and increasingly the broad-leaved peppermint (E. dives var. Type). 3. The perfumery oils containing mainly citronellal, such as the lemon-scented eucalyptus (E. citriodora). See also Botanical Classification section.

HERBAL/FOLK TRADITION: A traditional household remedy in Australia, the leaves and oil are especially used for respiratory ailments such as bronchitis and croup, and the dried leaves are smoked like tobacco for asthma. It is also used for feverish conditions (malaria, typhoid, cholera, etc.) and skin problems like burns, ulcers and wounds. Aqueous extracts are used for aching joints, bacterial dysentery, ringworms, tuberculosis, etc. and employed for similar reasons in western and eastern medicine. The wood is also used for timber production in Spain.

Fragonia

Agonis fragrans

FAMILY: Myrtaceae

SYNONYMS: Taxandria fragrans, coarse tea-tree.

GENERAL DESCRIPTION: Agonis is a genus comprising four species, all of which are native to Western Australia. The species generally have fibrous, brown bark, dull green leaves and inflorescences of small, white flowers. They are best known and most readily identified by the powerful peppermint or eucalyptus-like odour emitted when the leaves are crushed or torn. A. fragrans is a small shrub which grows up to 2.5 metres high, with narrow leaves and clusters of small white flowers, characteristic of the genus.

DISTRIBUTION: As a wild native species, fragonia (A. fragrans) has limited distribution in Western Australia, growing near the coast in the south-west region and being reliant on its winter rains and drier summers. For commercial purposes, A. fragrans is grown in large plantations in south-western Australia.

OTHER SPECIES: The Myrtaceae is a large family of plants with over 3,000 species. It is one of the most important families from an aromatherapy perspective, as it includes not only members of the Agonis genus (which includes trees such as A. flexuosa, the Western Australian peppermint) but also hundreds of aromatic plants from the Eucalyptus, Leptospermum, Melaleuca, Myrtus and Pimenta genera. There are several varying chemotypes of A. fragrans, but fragonia essential oil has a unique balance of primary constituents, which imparts its particular therapeutic qualities.

HERBAL/FOLK TRADITION: The name Agonis derives from the Greek agon, meaning ‘gathering’ or ‘collection’, in reference to the tightly clustered flowers. Traditional knowledge on A. fragrans has never been recorded, and there is no known use of the plant by early settlers. The species only came to the forefront at around the turn of the century when a husband-and-wife team heard about the local plant and began to explore its potential. Having selected superior genetic varieties, they established a small plantation of these shrubs on their property in south-west Western Australia in 2001. The essential oil distilled from this specific plant and chemotype is thus relatively new to the aromatherapy industry. Indeed it has only recently been given its common name ‘fragonia’ by its discoverer Chris Robinson, and has since been trademarked as FragoniaTM. In a series of tests, the University of Western Australia demonstrated that fragonia oil has anti-inflammatory properties and significant anti-microbial activity, similar to tea tree oil.

ACTIONS: Analgesic (mild), antibacterial, anti-inflammatory, antifungal, antimicrobial, anti-infectious, antiseptic, expectorant, immuno-tonic, nervine, regulating.

EXTRACTION: An essential oil by steam distillation from the stems, twigs and leaves.

CHARACTERISTICS: A pale, watery liquid with a pleasant slightly citrus, fresh-clean and faintly medicinal top note, mixed with a slight spicy, earthy and balsamic undertone: more pleasing than tea tree. It blends well with niaouli, eucalyptus, myrtle, lemon myrtle, rosemary and tea tree.

PRINCIPAL CONSTITUENTS: Primary constituents are 1,8-cineole, alpha-pinene and linalool. From a chemical perspective, it is an extremely well-balanced oil, with the oxides (1,8-cineole), monoterpenes (alpha-pinene) and monoterpenols (linalool, geraniol, terpineol and others) in a near perfect 1:1:1 ratio.

SAFETY DATA: Fragonia essential oil is non-toxic, non-irritant and non-sensitizing: an extremely mild oil when applied to the skin and safe for children.

AROMATHERAPY/HOME: USE:

Skin Care: Cuts, bites, stings and general skin care.

Circulation Muscles And Joints: Aching muscles and joints, arthritis, rheumatism.

Respiratory System: Asthma, bronchitis, coughs, colds, influenza, sinusitis, tonsillitis.

Genito-Urinary System: Candida (thrush), menstrual pain and breast tenderness, vaginitis.

Immune System: Powerful immune-system tonic and restorative.

Nervous System: Anxiety, depression, emotional blockages, grief, insomnia, nervous debility and tension, mood swings, stress.

OTHER USES: Many Agonis species are used as decorative garden plants while sprigs of the white flowers of A. fragrans are cut and used in the florist industry. Fragonia oil is now being used in the phyto-cosmetic industry, e.g. for soaps and skin care products. The oil can also be used as a natural, fresh-smelling disinfectant around the home, e.g. as a room fragrance, in the laundry and for cleaning bathroom and kitchen surfaces.... fragonia

Niaouli

Melaleuca viridiflora

FAMILY: Myrtaceae

SYNONYMS: M. quinquenervia, ‘gomenol’.

GENERAL DESCRIPTION: An evergreen tree with a flexible trunk and spongy bark, pointed linear leaves and bearing spikes of sessile yellowish flowers. The leaves have a strong aromatic scent when they are crushed.

DISTRIBUTION: Native to Australia, New Caledonia, and the French Pacific Islands. The majority of the oil is produced in Australia and Tasmania.

OTHER SPECIES: A typical member of the ‘tea tree’ group of oils; the oil is similar to cajeput. There is another physiological form of M. viridiflora called ‘Variety A’, which was originally developed to provide a natural source of nerolidol, the main constituent of its essential oil.

HERBAL/FOLK TRADITION: It is used locally for a wide variety of ailments, such as aches and pains, respiratory conditions, cuts and infections; it is also used to purify the water. The name ‘gomenol’ derives from the fact that it used to be shipped from Gomen in the French East Indies.

ACTIONS: Analgesic, anthelmintic, anticatarrhal, antirheumatic, antiseptic, antispasmodic, bactericidal, balsamic, cicatrisant, diaphoretic, expectorant, regulator, stimulant, vermifuge.

Manuka

Leptospermum scoparium

FAMILY: Myrtaceae

SYNONYMS: New Zealand tea tree, kahikatoa, red manuka, manex.

GENERAL DESCRIPTION: The Manuka plant is an elegant, bushy evergreen shrub with deep green small spiky leaves that bears small flowers of white to pink in colour. The blossom is produced from September to February and most profusely in the later months. Its size ranges from a creeping plant to a small tree – trees can reach heights of up to 8 metres, especially when found within dense woodland. The leaves and flowers are strongly aromatic.

DISTRIBUTION: Manuka is the only Leptospermum species native to New Zealand, where it is widely distributed in various climatic and altitudinal zones. The physical characteristics, such as flower and leaf colour, leaf size and shape, branching habit, and foliage density vary considerably among populations. The plant can now be found in Australia where it seems to acclimatize well to varied terrain from marshland to dry mountain slopes. The essential oil is generally harvested from wild plants, as little farming of Manuka is currently undertaken.

OTHER SPECIES: The family Myrtaceae yields many valuable essential oils including eucalyptus, myrtle and tea tree. Another native tree of New Zealand called kanuka (Kunzea ericoides), sometimes called white or tree manuka, although superficially similar to L. scoparium in that both are collectively known as ‘tea trees’, is actually genetically a very distinct species. Kanuka in its typical form can grow into a tree up to 30 metres tall. It is also used to produce an essential oil.

HERBAL/FOLK TRADITION: For centuries, New Zealand Maori have used manuka to treat a wide range of complaints. Early New Zealand records indicate that the plant’s bark, leaves, sap and seed capsules were used in beverages and medicinal preparations. A decoction of the leaves was drunk for urinary complaints and as a febrifuge. The steam from leaves boiled in water was inhaled for head colds. A decoction was prepared from the leaves and bark and the warm liquid was rubbed on stiff muscles and aching joints. The emollient white gum, called ‘pai manuka’, was given to nursing babies and also used to treat scalds and burns. Chewing the bark is said to have a relaxing effect and enhance sleep. It is said that Captain James Cook used the leaves of the plant as a tea to combat scurvy during long explorations of the southern hemisphere; later, early European settlers of New Zealand adopted Captain Cook’s use of the plant as a tea.

Recently, scientists have confirmed that manuka oil is up to 33 times stronger than tea tree essential oil for protecting against specific strains of bacteria; it is also effective against the MRSA (Methicillin-Resistant Staph. Aureus) bacteria, which is resistant to normal antibiotics.

ACTIONS: Analgesic, antibacterial, antibiotic, antifungal, antihistamine, anti-inflammatory, anti-infectious, antimicrobial, antiseptic, astringent, deodorant, digestive, expectorant, immune stimulant, insecticide, sedative, vulnerary.

EXTRACTION: Steam distilled from the leaves, twigs and branches.

CHARACTERISTICS: A mobile liquid with a distinctive fresh, spicy, herbaceous aroma with a honey-like sweetness. It blends well with bay leaf, bergamot, black pepper, cajuput, cedarwood atlas, cinnamon, clove bud, elemi, ginger, juniper, lavender, nutmeg, peppermint, rose, rosemary, sandalwood, thyme, vetiver and ylang ylang.

PRINCIPAL CONSTITUENTS: The main active constituents of manuka oil are isoleptospermone, ?-pinene, ?-pinene, myrcene, ?-cymene, 1,8-cineole, linalol, methylcinnamate, ?-farnesine, isoleptospermone, leptospermone, sesquiterpenes such as cadina-3, 5-diene and ?-amorphene, and triketones. However, within the species of manuka there are at least nine different chemotypes: oil which contains high levels of triketones, found in the East Cape area of North Island in New Zealand appears to possess the greatest antimicrobial potential. Other chemotypes however are thought to reveal greater anti-inflammatory and analgesic tendencies. It is important to be aware of these various chemotypes when selecting an oil for therapeutic purposes.

SAFETY DATA: Generally it is thought to be non-sensitizing, non-toxic, and non-irritant. It can in some individuals, produce mild irritation but has a low irritancy compared to Australian tea tree oil. Avoid use during pregnancy because of spasmolytic activity.

AROMATHERAPY/HOME: USE

Skin care: Acne, abscesses, athlete’s foot skin, bed sores, blisters, boils, burns, carbuncles, cold sores, cracked skin, dandruff, dermatitis, eczema, fungal infections, insect bites and stings, lice, nail infections, oily skin, pimples, ringworm, sores, sunburn, tinea and ulcers.

Circulation, muscles and joints: Aches and pains, muscular tension, sprains and stiffness in joints, rheumatism.

Respiratory system: Coughs, cold, ’flu congestion, as well as asthma and hayfever.

Immune system: Tonic

Nervous system: Nervous debility.

OTHER USES: The essential oil is much used in phyto-cosmetic and pharmaceutical preparations mainly for its potent antimicrobial properties. Commercial development of the essential oil has led to a range of products for the topical treatment of various conditions including joint pain, eczema and psoriasis. The oil is also used in perfumes and soaps. The scented flowers of the shrub attract bees, which are used for making the popular manuka honey.... manuka

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.
