Coptis chinensis is an important Chinese herbal medicine and is widely used in more than 50 countries and regions around the world, including China, Japan, Malaysia, and Singapore. It has the effects of clearing away heat and drying dampness, purging fire and detoxifying.

Tianjiang Pharmaceutical cooperated with China Pharmaceutical University to conduct research on the US Pharmacopoeia quality standards of Coptis chinensis extract granules. For the complex system of traditional Chinese medicine, the two parties jointly drafted and formulated the quality standard of Coptis chinensis extract granules based on traditional Chinese medicine theory and modern pharmaceutical research technology.

After 5 years of painstaking research, summary and review, Tianjiang Pharmaceutical Co., Ltd. and China Pharmaceutical University cooperated to develop the quality standards of the United States Pharmacopoeia of Coptidis Extract Granules. This standard is currently included in the HMC Department of the United States Pharmacopoeia, becoming the first Chinese medicine extract granule standard included in the United States Pharmacopoeia in the world, which is a milestone for the internationalization of Chinese medicine extract granules.
