Research Summary

Evidence Level: Insufficient

Lemon myrtle has a tradition as a fragrant calming, immune, and antioxidant tea; preclinical work shows strong antimicrobial and antioxidant activity from citral. Clinical evidence is insufficient; it is not a treatment for infection or any disease, though it remains a bright, caffeine-free cup.

Evidence levels reflect the currently available scientific literature and may change as new research emerges. Where evidence is limited or conflicting, this is stated plainly.
