Coptis chinensis (scientific name: Coptis chinensis), a perennial herbaceous plant that prefers cold and moist places, belongs to the genus Coptis chinensis in the family Trichoaceae. Coptis chinensis is also a commonly used traditional Chinese medicine, which was first recorded in the "Shennong's Materia Medica", because its rhizome is bead-shaped and yellow, so it is called Coptis chinensis. Its taste is extremely bitter in the mouth, and there is a saying that "dumb people eat Coptis chinensis, and they can't say that they are bitter", which shows the taste.

Also known as Wang Lian and Zhi Lian. It is the dried rhizome of Coptis chinensis Franch, Coptis deltoidea C. Y. Cheng et Hsiao, and Coptis teeta Wall. They are known as "Weilian", "Yalian", and "Yunlian". Other alternative varieties include Coptis omeiensis (Chen) C. Y. Cheng and Coptis quinquesecta.

Growth habits

Coptis chinensis is generally distributed in the high mountainous areas of 1200~1800m, which requires a natural environment with low temperature and high air humidity. Fear of heat and drought. Cannot withstand strong sunlight and prefers weak light, so shade is required. The roots are shallow, distributed in the soil layer of 5~10cm, suitable for loose and fertile topsoil, rich humus, deep soil, pH 5.5~6.5, slightly acidic.

Most of the medicinal herbs are clustered and often curved, shaped like chicken feet, commonly known as "chicken feet lian", and its single rhizome is 3-6 cm long and 0.3-0.8 cm in diameter. The surface is rough, with irregular nodular protrusions, fibrous roots and fibrous root residues. The surface of the internode is as smooth as a stem, and it is commonly known as "crossing a bridge".
