Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

Alterative;  Antibacterial;  Antiseptic;  Aromatherapy;  Diaphoretic;  Expectorant.

Tea tree, and in particular its essential oil, is one of the most important natural antiseptics and it merits a place in every medicine chest[254]. It is useful for treating stings, burns, wounds and skin infections of all kinds[254]. An essential oil obtained from the leaves and twigs is strongly antiseptic, diaphoretic and expectorant[156, 157, 238]. It stimulates the immune system and is effective against a broad range of bacterial and fungal infections[238]. Internally, it is used in the treatment of chronic and some acute infections, notably cystitis, glandular fever and chronic fatigue syndrome[254]. It is used externally in the treatment of thrush, vaginal infections, acne, athlete's foot, verrucae, warts, insect bites, cold sores and nits[238]. It is applied neat to verrucae, warts and nits, but is diluted with a carrier oil such as almond for other uses[238]. The oil is non-irritant[238]. Another report says that high quality oils contain about 40% terpinen-4-ol, which is well tolerated by the skin and 5% cineol which is irritant. However, in poor quality oils the levels of cineol can exceed 10% and in some cases up to 65%[254]. The essential oil is used in aromatherapy. Its keyword is 'Antiseptic'[210].


Other Uses
Essential;  Wood.

An essential oil is obtained from the leaves[156, 157]. It is strongly germicidal and is also used in dentistry, deodorants, soaps, mouthwashes etc[156, 238]. Wood - very durable in wet conditions and in damp ground[167].
Cultivation details
Industrial Crop: Medicinal;  Management: Coppice;  Management: Standard;  Regional Crop.

Requires a fertile, well-drained moisture retentive lime-free soil in full sun[182]. Prefers a soil that does not contain much nitrogen[188]. Plants are shade tolerant and succeed in most soils and aspects except dry conditions when they are grown in Australian gardens[157]. This species is not very cold hardy and is only likely to succeed outdoors in the very mildest parts of Britain. It tolerates temperatures down to at least -7°c in Australian gardens[157] but this cannot be translated directly to British gardens because of our cooler summers and longer colder and wetter winters. Seed takes about 12 months to develop on the plant, the woody seed capsules persist for 3 or more years[200]. Any pruning is best done after the plants have flowered with the intention of maintaining a compact habit[200]. Hybridizes freely with other members of this genus[200]. Plants in this genus are notably resistant to honey fungus[200].
Seed - surface sow in spring or autumn onto a pot of permanently moist soil in a warm greenhouse. Emmerse in 5cm of water and do not water from overhead. Grow on until the seedlings are 0.5cm tall then remove from the water and pot up a week later. Seedlings are liable to damp off when grown this way, sowing the seed thinly, good ventilation and hygiene are essential for success[200]. Grow the plants on for at least their first winter in a greenhouse and then plant them out in late spring or early summer, after the last expected frosts. Consider giving the plants some protection from the cold for their first few winters outdoors. Cuttings of half-ripe lateral shoots with a heel, July/August in a frame[200].

Tea tree oil has been recognized as a potent antiseptic in Australia anecdotally for much longer than there has been scientific evidence. However, recent studies support a role for tea tree oil in skin care and treatment of various ailments. - From the Wiki Melaleuca Tea Tree Oil page

The applications for Melaleuca include: Cosmetics, personal care, hair care, first aid, pet care, antiseptic, antibacterial, and antifungal products. P.S. Don't confuse the 'Melaleuca Tea Tree" with other species of melaleuca like 'Melaleuca quinquenervia' which are considered invasive in some areas.

Melaleuca oil is the best thing that ever happened to my family and me. It is so wonderful that I don't know how I could have possibly lived with out it! It has amazing properties. First of all it is an antiseptic, plus it sooths and penetrates, its non caustic, a solvent and its aromatic. Because all of this it has amazing healing properties!!!

I just recently learned about Melaleuca Oil and am amazed at the scope of usage for this product of nature. It now replaces many products in my house and everyday I learn some new way to use it. I lived in Australia 24 years ago and I can't believe I never heard of it while we were there. It is so awesome!!

Tree tea oil was really good for the keloid behind my ear after my 4th peircing. It cleared up in about a week. It's also really great for bug bites.

Hi I have a dog that is extremely allergic to Tea Tree Oil in all its forms, especially plants and trees. Where can I obtain information, especially pictures of all plants and trees that contain it? Regards

i want to grow tea tree in portugal. anyone know where to buy seeds/plants?

I use tea tree oil for loads of things, the two best are as a deoderant. It is good for this as it has a strong smell itself and also kill bacteria that cause bad smells, it lasts for days sometimes. Also I use it to treat boils I just put a few drops on a plaster and put it on the boil and leave it over night and it kills all the bacteria. It's also good for spots but does tend to dry the skin so carrier oils would be best for facial application, although I don't tend to care too much, it goes away after a while and you could also just use moisturiser.

Well, is tea tree an alternative against the Mexican flu? Treatment: - put some drops of oil in a glas with water. It will clean the atmotsfere and flys don't come in your house. to be sure if this continues works. Controll the glas of water every day, fill it up with water and drops of tea tree oil - teatree lotion: helps against insects coming on your skin Use it once a day - teatree helps healing wounds, you barely can't see a scar after healing. Preventive I use teatree against the Mexican flu. But: stay healthy with lots of fruit, vegetables etc, bio-dynamic grown!! Roodborst
