Houttuynia Cordata Extract

A leaf extract long used in Korean and Chinese folk medicine and popularized in K-beauty as "heartleaf." Small in-vitro and cell-culture studies suggest anti-inflammatory and antioxidant activity, but there is little rigorous human clinical trial data isolating the extract itself, so soothing claims should be read as plausible rather than proven.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
