Chemical, physical and antimicrobial properties of essential oils of Leptospermum scoparium and Kunzea ericoides.

Porter NG, Wilkins AL.

New Zealand Institute for Crop and Food Research Ltd., Christchurch, New Zealand.

The major components of commercial New Zealand essential oils of Leptospermum scoparium (manuka) and Kunzea ericoides (kanuka) are identified. In the manuka oil, monoterpenes are present at low levels (< or = 3%). Sesquiterpene hydrocarbons are predominant (> or = 60%) and include groups possessing cubebene/copaene, elemene, gurjunene/aromadendrene, farnesene/ caryophyllene, selinene, calamenene and cadinene skeletons. Oxygenated sesquiterpenes and triketones are present (< or = 30%). The antimicrobial activity of the manuka oil was associated with a fraction containing three major and three trace triketones, two of the latter were previously unreported. Kanuka oil was characterized by high levels of alpha-pinene (> 50%) and lower levels (< 10%) of viridiflorol and viridiflorene. GC-MS and GC-FID detector responses to the same components were noticeably different for some major components, including the triketones. Non-commercial manuka oils from different sites differed widely in composition and could be separated into four groups by the presence and levels of distinctive components. The density and refractive index of manuka and kanuka oils were closely correlated with the total sesquiterpene levels. The density of the commercial manuka oil was closely correlated with the level of the triketones. Simple density measurements enabled discrimination between the commercial oil and oils from other sites, and prediction of antimicrobial activity.

Essential oils from New Zealand manuka: triketone and other chemotypes of Leptospermum scoparium. Douglas MH, van Klink JW, Smallfield BM, Perry NB, Anderson RE, Johnstone P, Weavers RT. New Zealand Institute for Crop & Food Research Limited, Invermay Agricultural Centre, Private Bag 50034, Mosgiel, New Zealand. The triketone chemotype of manuka, Leptospermum scoparium (Myrtaceae), is commercially important because of its antimicrobial activity. Oils from 36 individual plants on the East Cape of New Zealand all showed similar high triketone contents (>20% total triketones) with little seasonal variation. Analyses of oils from 261 individual manuka plants collected from 87 sites throughout New Zealand showed that the high triketone chemotype was localised on the East Cape, although oils with triketone levels up to 20% were found in the Marlborough Sounds area of the South Island. Cluster analysis revealed other chemotypes localised on other areas. Ten further chemotypes are described: alpha-pinene; sesquiterpene-rich with high myrcene; sesquiterpene-rich with elevated caryophyllene and humulene; sesquiterpene-rich with an unidentified sesquiterpene hydrocarbon; high geranyl acetate; sesquiterpene-rich with high gamma-ylangene + alpha-copaene and elevated triketones; sesquiterpene-rich with no distinctive components; sesquiterpene-rich with high trans-methyl cinnamate; high linalol; and sesquiterpene-rich with elevated elemene and selinene. Some of the chemotypes contained aroma compounds at relatively high levels, with a geranyl acetate-rich oil being most notable. Possible origins for this complex array of chemotypes are proposed.

Manuka Oil has been shown to be effective when used as a:

bullet

Historical Use

bullet

Manuka, as it is called by most New Zealanders, was used in pre-European times by the traditional people of New Zealand, the Maori, and still is. 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 it enhances sleep.

bullet

Active Constituents

bullet

A gas chromatographic analysis of Manuka Oil at the University of Waikato's chemistry department showed it contains monoterpene hydrocarbons, a-cubebene, b-pinene, r-cymene, g-terpinene, a-copaene, b-caryophyllene, aromadendrene, calamanene, limonene, and myrcene; the oxide 1,8-cineole; a terpene alcohol, linalool; and esters. Tri-ketones, triterpenoids and flavonoids have also been isolated in East Cape Chemotype Manuka Oil.

bullet
The 1,8-cineole when taken internally is a stimulating expectorant and when applied topically it is a mild aesthetic and antiseptic.
bullet
Limonene also has an expectorant and antiviral action.
bullet
Pinene, also found in cypress and pine oils, and cymene, found in thyme oil, have a powerful antiseptic action.
bullet
L. scoparium has a range of therapeutic actions and medicinal uses similar to Melaleuca alternifolia (Tea Tree Oil).
bullet
Linalool (as shown by researchers at the enthopharmacology laboratory at the University in Porto Alegre, Brazil) has effective sedative effects and is rapidly absorbed through the skin and nasal mucosa.
bullet

Research has shown that East Cape Manuka Oils have more powerful antiseptic and antifungal action when compared to Melaleuca alternifolia (Tea Tree Oil).

bullet

Research carried out in both Britain and New Zealand by the Cawthron Institute and Waikato University has shown a broad spectrum antibiotic action..

bullet

Important Note:

bullet

It is very important to understand that only East Cape Chemotype Manuka has potent antimicrobial characteristics. Also because of this products unique steam distillation method, a much higher Tiketone level is achieved compared with another East Cape Chemotype being sold.

In the Journal of Agriculture and Food Chemistry (Jan. 1990, v. 38), Molan, Wilkins and Holland researched the components responsible for the exceptionally high antibacterial activity of honey from Manuka flowers. They tested fractions of the honey for activity against staphylococcus aureus in particular, which is the bacteria that causes skin infections such as impetigo.

bullet

Perhaps most interesting with the current emergence of strains of antibiotic-resistant bacteria is that laboratory tests have indicated Manuka Oils effectiveness as a treatment against some antibiotic-resistant organisms.

bullet

Aromatherapy Uses

bullet

Manuka Oil is rapidly gaining popularity in the field of Aromatherapy.

bullet

Some aromatherapists believe that although the effectiveness of Manuka Oil as a bactericide and fungicide is dramatic- Manuka Oil has another side to it.

bullet

A leading German Aromatherapist- Ruth von Braunschweig reports on the sensual, "feel good" side of Manuka Oil, stating it to be beneficial for people with over sensitive nervous systems and those who suffer from stress and anxiety. Conditions that often manifest themselves in allergic reactions. She states that "Manuka Oil" is very effective for many skin problems. It strengthens the psyche and at the same time stabilizes the skin, it makes it more resistant, because it is relaxing for the skin nerves as well as cell activating and regenerating for the outer skin layers. The skin doesn't overreact constantly, - it doesn't come out in a rash so fast. Therefore Manuka is helpful for sensitive skin, especially itching, acne, badly healing skin, inclination to fungal infections, ulcers, bedsores and infections.


bullet

Household Uses

bullet

Manuka Oil is extremely useful as a household disinfectant.

bullet

For an antiseptic action in the laundry, add half a teaspoon of oil to each wash load.

bullet

It is used as a flavouring and antiseptic agent in mouthwashes.

bullet

 It can also be used to purify drinking water.

bullet

Perfumery Uses

bullet

Manuka Oil has a honey-like aroma, sweet yet herbaceous and medicinal.

bullet

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.

bullet

ManukaOil.com has available a Pure Manuka Oil with lowered aroma.

bullet

Cautions

bullet

Acute toxicity can occur if it is administered in amounts above the stated daily dose.

bullet

It can, in some individuals, produce a mild irritancy to the skin but has a low irritancy compared to Australian tea tree oil.

bullet

In tests conducted in England at Huntington Life Sciences and at the Wellington Clinical School, New Zealand, on application of undiluted oil to the skin of 30 subjects, there were no reports of skin irritancy.

bullet

If irritation or other negative effects occur, discontinue use and consult a medical practitioner before resuming.

Manuka Oil and Manuka Cream

Oil from a Manuka tree growing in the Te Araroa region of the East Cape of New Zealand shows a much higher antibacterial activity than oil from Manuka trees in other regions.

"Manuka Oil was 20-30 times more active than Australian Tea Tree Oil"
for gram positive bacteria, and 5-10 times more active for fungi.

New Zealand Manuka is Effective Against Bacteria and Fungus Infections
Uses: Acne, Pimples, Eczema, Ring Worm, Skin Rash, Chafing, Itching, Dandruff, Bed Sores, Athlete's Foot, Nail Bed Infections, Foot Odor, Body Odor, Cuts, Abrasions, Insect Bites & Stings, Sunburn, Muscle Ache, Aching Joints,
and Aromatherapy for Stress and Anxiety

Traditional Uses of the Manuka Tree

Only in the last decade has the Manuka tree begun to be recognized and understood through science, but the Maori (who are the indigenous people of New Zealand) have long known the strength and healing ability of the Manuka tree.

Manuka has been used to treat a range of skin problems, including chronic sores, ring worm and eczema. Others reported that a decoction of Manuka leaves was drunk for urinary complaints and to reduce fever. The leaves were boiled in water and inhaled for head colds, blocked sinuses, hay fever, even bronchitis and asthma. Leaves and bark were boiled together, and the warm liquid was rubbed on stiff backs and rheumatic joints. The leaves and young branches were put into vapor baths. The crushed Manuka leaves were applied as a poultice for many skin diseases and were directly applied to wounds and deep gashes to enhance healing and reduce the risk of infection. The young shoots of the Manuka tree were chewed and swallowed for dysentery.  The bark, the sap, and the seed capsules of the Manuka tree were also used extensively for treating various ailments.

Clearly, Manuka was an important medicinal plant, both to the Maori and to the original European settlers who, in the early years of settlement, depended on Maori knowledge of medicinal plants in treating their own illnesses.

Scientific Research on Manuka

Although the Manuka tree of New Zealand had attracted scientific interest in the past, little had been found of real importance - until some Manuka oil samples were tested by Dr. Cooke of the Cawthron Institute and showed some remarkable results.

The Cawthron Institute research, conducted on behalf of the Company, showed that the oil produced from the Manuka trees in the Te Araroa region of the East Cape displayed antimicrobial activity far greater than had been seen with other Manuka oil samples and greater than many other natural oils.

The testing showed Manuka Oil to be active against a wide range of micro-organisms that cause irritation and infection of the skin and body. Some of them were serious, such as MRSA (antibiotic-resistant Staphylococcus aureus, more commonly known as the H-bug) and others were more common ones, such as those that cause Athlete's Foot.

The Cawthron Institute concluded that "Manuka Oil was 20 to 30 times more active than Australian Tea Tree Oil" for gram positive bacteria, and 5 to 10 times more active for fungi. Further testing has confirmed that Manuka Oil is effective in combating bacteria including those associated with acne or eczema, as well as foot and body odor.
