What is Japanese Ampelopsis Root?

Japanese Ampelopsis Root (bai lian, 白蔹), also known as the Japanese Peppervine Root or Radix Ampelopsis, is the dried root of Ampelopsis Japonica. This woody and ornamental vine is native to Asia and North America. This plant grows at an extremely quick rate and it can reach a height of more than 15 feet at times. 

Japanese Ampelopsis resembles a grape vine, where it has dark green leaves, tiny flowers and curved tendrils. Japanese Ampelopsis Root grows berries of various colours, mostly dark-blue, and its flowers bloom in mid to late Summer. Its seeds ripen in the fall and the plant withers afterwards, which is when the roots will be dug up, cleaned and dried for medicinal usage.

In Traditional Chinese Medicine (TCM), Japanese Ampelopsis Root is cool in nature. This means that it can help individuals who have too much Heat, such as those experiencing a Yang Excess or a Yin Deficiency, to restore a healthy yin-yang balance. Bitter and pungent in taste, this herb can cleanse the body by clearing Heat, drying Dampness and promoting elimination via urination or bowel movements. Also, the herb can promote the circulation of qi and body fluids. In particular, Japanese Ampelopsis Root targets the Heart, Liver and stomach.
