Evidence notes
Traditional use in Chinese medicine is well-documented, but human clinical trials are limited and mostly conducted in Asia. Preclinical studies show promise for bioactive compounds, but evidence in Western populations remains preliminary. No strong RCT evidence in primary literature.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
