Cynanchum root (Bai-qian) – The Herb Used in Traditional Systems to Support Normal Cough Relief and Lung FunctionCynanchum root (Bai-qian), also known as "White Swallow-wort Rhizome" or "Cynanchum Rhizome," is the traditional Chinese name for the dried rhizome (root network) of Cynanchum stauntonii, a warm, acrid herb from the Apocynaceae family that has been part of traditional Chinese herbal systems for over 2000 years. This warm herb is particularly known for its ability to relieve normal cough, transform normal phlegm accumulation, support normal lung function, restore normal respiratory comfort and promote normal bronchus health – making it an ideal choice for people with a tendency toward normal cough, normal asthma symptoms, normal bronchitis and normal phlegm-accumulation problems.Traditional Understanding in TCM SystemsWithin traditional Chinese medicine, cynanchum root (Bai-qian) is described as a warm, acrid herb with a clearly "Qi-descending" character.
