The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.
Adults (18 years and older)
Although there is no proven effective dose, a common dose studied in trials is 5-10% tea tree oil in gel or shampoo form applied on the skin daily for up to four weeks. While 100% tea tree oil is sometimes used for certain conditions, such as fungal nail infections, it is often diluted with inactive ingredients. Due to reports of severe side effects after tea tree oil ingestion, it is strongly recommended that tea tree oil not be taken by mouth. Although tea tree oil solution has been used as a mouthwash, it should not be swallowed.
Children (younger than 18 years)
There is insufficient research to recommend the safe use of tea tree oil in children.
