What’s inside
Houttuynia Cordata ExtractLimited concern
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.
