Coptis

History

There are several common names for this stemless perennial herb, which is native to China. Chinese goldthread, ch’uan-lien, coptis rhizome, golden thread, and huang lian are all used to describe the dried rhizomes. The yellow color of the rhizome is largely due to the high alkaloid content and it has been used as a dye as well as a traditional Chinese herbal remedy. Most of the historical information on use of this plant comes to us from traditional Chinese, Japanese, and Korean herbal medicine. This plant can be used as a substitute for Goldenseal.

Function

In Traditional Chinese Medicine (TCM) color as well as configuration of an herb suggests the therapeutic corresponding action. Yellow herbs tend to affect the Stomach and Spleen (here referring to systems not specific organs), and the adverse climate of dampness. Bitter Yellow roots are said to clear Damp Heat through eliminative action. It is no surprise to find that it has been used to promote a healthy digestive environment, as well as a healthy microbial environment in cases where immune support is indicated. Berberine alkaloids in Coptis have been researched for their influence on microbes in animal tissues.
