Tea tree comes in cream, ointment, lotion, and soap forms. It can also be found as pure oil. Tea tree oil has been used as a spot treatment for acne, for fungal infections of the toenails, and diluted as a mouthwash for oral yeast (thrush). When gargling, the solution is never swallowed after use.
For application on the toenails, tea tree can be used at a strength of 70-100%. Any application to the skin or as a gargle or douche should be diluted under qualified supervision.
