Xi Yang Shen (American Ginseng)
American Ginseng, Xi Yang Shen, is cool in nature and is stronger in nourishing the yin and sedating fire, while its qi-tonic action is weaker than that of Ren Shen. Xi Yang Shen is best used for those with both qi and yin deficiencies as is often seen in Lung yin-deficient fire.
