Rating (out of 5): 2

Melaleuca alternifolia, commonly known as tea tree oil, has a long history of traditional use in Australia for various skin ailments, including minor wounds, cuts, and blisters. Indigenous Australians have used crushed tea tree leaves as a topical treatment for skin infections and injuries, capitalizing on its reported antiseptic and anti-inflammatory properties. While scientific studies have validated tea tree oil’s antimicrobial effects against certain bacteria and fungi, there is limited direct research specifically investigating its efficacy for treating or supporting blister healing in humans. Most available evidence for its use on blisters is anecdotal or based on case reports, rather than controlled clinical trials.

The few studies that reference tea tree oil in the context of skin integrity suggest that its antiseptic properties may help reduce the risk of secondary infection in blisters that have ruptured. However, there is a lack of robust, high-quality research focusing solely on blister management. As such, the use of Melaleuca alternifolia for blisters is primarily justified by tradition and historical use rather than strong scientific validation. Caution is advised, as tea tree oil can cause skin irritation or allergic reactions in some individuals, especially if applied undiluted. Overall, while there is some rationale for its use based on its antimicrobial properties, more research is needed to firmly establish its efficacy and safety for blister treatment.
