  • Tea tree oil comes from the leaves of the tea tree. It was traditionally used in wound treatment by the Aboriginal population of Australia to prevent infection. Until the advent of antibiotics during World War II, tea tree oil was often used in Australian factories to prevent wound infections.
  • Its antibacterial and antifungal properties make it effective, and it is generally safe when used topically.
  • A 5% tea tree oil shampoo helps treat dandruff.
  • Tea tree oil (100% concentration) can be used for up to 6 months to treat fungal infections of the feet and toenails.
  • Tea tree oil with lavender is as effective as permethrin for treating head lice.
  • The benefits of tea tree oil application outweigh the risk of potential harm. There are no reports of serious adverse reactions.


  • Tea tree oil is very irritating to facial skin and better and safer alternatives exist for treating acne.
  • Side effects, while rare, may include dermatitis (skin inflammation causing burning and redness), weakness and low white blood cell counts.

Do not take tea tree oil orally. Concerns exist about harm to the central nervous system in children when ingested. Do a patch test before using. People who are allergic to tea tree oil should avoid this product. Also, those who are taking antibiotics, antifungal and anti-cancer agents should not take it because of possible drug interactions.

DOSAGE:100% for treating fungal infection of feet. Test for reaction before using consistently. 5% gel for scalp and face.

CONCLUSION:We conclude that tea tree oil is a safe and effective supplement for fungal infections, athlete’s foot, lice, dandruff and warts, but that it is not likely to be effective for treating acne. Tea tree oil has been widely used for a long time, so it seems safe, but there are not many studies to confirm this. It is not beneficial for acne use and may cause excessive skin drying.
