Melaleuca alternifolia, commonly known as tea tree oil, is used externally to support the healing of ulcerations, including skin ulcers, primarily due to its antimicrobial and anti-inflammatory properties. Scientific studies have demonstrated that tea tree oil exhibits broad-spectrum antibacterial, antifungal, and antiviral activity, which can help prevent infection in ulcerated skin. Several in vitro and in vivo studies have shown that components of tea tree oil, such as terpinen-4-ol, inhibit pathogens commonly associated with skin ulcerations, including Staphylococcus aureus and Pseudomonas aeruginosa.

Clinical evidence supporting tea tree oil in the management of chronic wounds and ulcerations is emerging. Small-scale clinical trials and case reports suggest that topical application of tea tree oil preparations can reduce microbial load, decrease odor, and improve healing in chronic ulcers, particularly when standard treatments are insufficient. For example, a 2004 case series published in the Journal of Wound Care described positive outcomes using tea tree oil in patients with chronic leg ulcers. However, high-quality randomized controlled trials are limited, and concerns about skin irritation and allergic reactions exist.

In summary, there is moderate scientific evidence supporting the external use of Melaleuca alternifolia for ulcerations, primarily due to its antimicrobial effects and some positive clinical observations, but more rigorous research is needed to fully establish its efficacy and safety in this context.
