Coptis chinensis, the Chinese goldthread, is a species of goldthread flowering plant native to China.

The rhizomes of Coptis chinensis contain the isoquinoline alkaloids berberine,[3] palmatine, and coptisine among others.

Coptis chinensis is one of the 50 fundamental herbs used in traditional Chinese medicine, where it is called duǎn è huánglián (Chinese: 短萼黄连).

It has been proved to have anti‐cancer, anti‐inflammatory, and anti‐bacterial properties and to help to improve cardiovascular conditions.

[4] Because of the strong coloring quality of berberine, it has been traditionally used as a dye, especially for wool and other fibers.
