Uses[edit]

Coptis teeta is used as a medicinal herb in China and the Himalayan regions of India where it is used as a bitter tonic for dyspepsia.[1] It is also believed to help insomnia in Chinese herbology.[citation needed] The roots contain the bitter alkaloid berberine. The dried roots (goldthread) were commercially marketed in Canada until the 1950s or early 60s, to be steeped into a "tea" and swabbed onto areas affected by thrush (candidiasis) infection.[citation needed]
