Rating (out of 5): 2

Melaleuca alternifolia, commonly known as tea tree oil, has been used traditionally for a variety of skin conditions, including warts. In recent years, some scientific investigations have explored its antiviral and immunomodulatory properties, which may be relevant to the treatment of warts—cutaneous growths caused by human papillomavirus (HPV) infection. A limited number of case reports and small studies suggest that topical application of tea tree oil may lead to resolution of warts. For example, a few case studies, such as one published in Complementary Therapies in Clinical Practice (2008), documented the successful clearance of warts after regular topical application of tea tree oil, presumably due to its antiviral and anti-inflammatory actions. In vitro studies have also shown that tea tree oil possesses activity against some viruses, and its terpinen-4-ol component may help stimulate local immune responses.

Despite these promising findings, robust clinical trials are lacking. The available evidence is mainly anecdotal or based on small-scale studies, so the scientific support for tea tree oil in wart treatment is still considered weak (rating: 2 out of 5). Nevertheless, tea tree oil is widely available and used by individuals seeking alternative treatments. While generally regarded as safe when used topically, it can cause skin irritation in some cases. In summary, scientific evidence supporting the use of Melaleuca alternifolia for warts is limited but not absent, and further research is needed to establish its efficacy and safety.
