Coptis is a genus of flowering plants in the family Ranunculaceae, commonly known as goldthread. The name goldthread comes from the bright yellow color of the root, which is rich in berberine, a compound with medicinal properties. These perennial herbs are native to East Asia and North America, thriving in cool, moist, and shaded environments such as forest understories and swampy areas. The plants typically have small, star-shaped flowers with white or greenish petals and finely divided leaves. Coptis species have been traditionally used in herbal medicine, particularly in Chinese and Japanese practices, to treat various ailments including digestive disorders, infections, and inflammation. The bitter taste of the roots is a hallmark of their medicinal use. Despite their benefits, the natural habitats of Coptis plants are increasingly threatened by habitat loss and overharvesting, prompting conservation efforts to ensure their sustainability.
