Rating (out of 5): 3

Melaleuca alternifolia, commonly known as tea tree oil, is widely used to support the healing of abrasions due to its antimicrobial and anti-inflammatory properties. Scientific evidence supports its use in this context, albeit to a moderate degree. Several in vitro studies have demonstrated that tea tree oil possesses significant antibacterial activity against common skin pathogens such as Staphylococcus aureus and Streptococcus pyogenes, which are often implicated in secondary infections of minor wounds and abrasions. This antimicrobial effect may help reduce the risk of infection when tea tree oil is applied to abrasions.

Additionally, research has indicated that tea tree oil can modulate inflammatory responses, potentially reducing swelling and promoting a more favorable healing environment. Clinical evidence is more limited: some small-scale clinical trials and case studies suggest that topical tea tree oil preparations may aid in wound healing and the prevention of infection, but larger, well-controlled studies are lacking. Safety studies also indicate that tea tree oil is generally well-tolerated when used topically, though allergic reactions can occur in sensitive individuals.

Historically, tea tree oil has been used in traditional medicine by Indigenous Australians for the treatment of skin injuries. Modern scientific studies provide a rationale for this traditional use, offering moderate scientific validation for its topical application to abrasions. However, due to the current limitations in large-scale clinical data, the evidence is rated as moderate (3 out of 5).
