Melaleuca alternifolia, commonly known as tea tree oil, is used to support or treat impetigo primarily due to its well-documented antimicrobial properties. Impetigo is a superficial bacterial skin infection, most often caused by Staphylococcus aureus and Streptococcus pyogenes. Several in vitro studies have demonstrated that tea tree oil exhibits significant antibacterial activity against these pathogens. For example, Carson et al. (2006) reviewed the antimicrobial activity of tea tree oil and concluded that it is effective against a variety of skin pathogens, including those responsible for impetigo. Additionally, a small randomized controlled trial (Dryden et al., 2004) compared tea tree oil with standard antibiotics and found comparable efficacy in the management of superficial skin infections, though the sample size was limited and the study was not exclusive to impetigo.

Historically, tea tree oil has been used in traditional medicine in Australia for its wound-healing and antimicrobial effects, but its modern application for impetigo is supported by laboratory and small clinical studies rather than extensive historical precedent. While the evidence is promising and suggests that tea tree oil may be a useful adjunct or alternative in mild cases of impetigo, larger, well-designed clinical trials are needed to fully establish its efficacy and safety. Current guidelines recommend conventional topical or oral antibiotics as first-line therapy, with tea tree oil considered a complementary option where appropriate.
