What the Research Says
Tea tree oil (Melaleuca alternifolia) has been studied extensively for its antimicrobial and anti-inflammatory properties. Here's what the science actually says — not the marketing.
- A landmark review found that tea tree oil demonstrates broad-spectrum antimicrobial activity against bacteria, fungi, and viruses, attributed primarily to its active compound terpinen-4-ol. (Carson, Hammer & Riley, Clinical Microbiology Reviews, 2006)
- A review in the International Journal of Dermatology found tea tree oil effective for acne, seborrheic dermatitis, and nail fungus, with terpinen-4-ol reducing pro-inflammatory cytokine activity. (Pazyar et al., Int J Dermatol, 2013)
- In vitro studies confirm tea tree oil disrupts bacterial cell membranes, preventing microbial colonization on skin surfaces. (Hammer, Carson & Riley, J Appl Microbiol, 2003)
