About Mai Men Dong
Traditional Chinese herb (tuber) used in respiratory/'yin tonic' formulas, often combined with other herbs (e.g., in TCM cough/cardiotonic formulas). Clinical evidence comes mostly from multi-herb TCM formula trials, not isolated RCTs of Ophiopogon alone; no meta-analyses support standalone efficacy.
