Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Tea Tree (Melaleuca alternifolia) has a long history of traditional use, particularly among the indigenous peoples of Australia, for treating a variety of skin infections and wounds, including those believed to be caused by viral pathogens. The essential oil derived from tea tree leaves has been applied topically in traditional medicine settings for its reputed antiseptic properties. While there is substantial scientific evidence supporting tea tree oil’s antibacterial and antifungal effects, evidence specifically supporting its efficacy against viral infections is limited. Some in vitro studies have demonstrated that tea tree oil and its main component, terpinen-4-ol, exhibit activity against certain viruses, such as herpes simplex virus (HSV), by disrupting viral envelopes or inhibiting viral replication. However, these findings have not been robustly confirmed in clinical trials, and there is a lack of high-quality human studies that demonstrate effectiveness for treating viral infections in practice. Overall, the use of tea tree oil for viral infections is primarily rooted in traditional use, and while there are some preliminary scientific findings suggesting potential antiviral properties, the evidence base remains weak. Its topical use for minor skin viral infections may persist in folk medicine, but it should not be relied upon as a primary or sole treatment for viral diseases.
