The Authentic berberine coptis

In the period of the Republic of China in the early 20th century, the annual output of Shizhu Huanglian was 4,000. In 1934 (the 23rd year of the Republic of China), the Bank of Sichuan compiled the "medicinal materials of Sichuan Province": "Weilian, only family species, produces stone columns exclusively". In 1959, "The History of Coptis" in "Journal of Sichuan Medical College" said: "The wild species of Emei and Hongya are well-known in the world, and the quality of stone pillar cultivation is good, and the output is national." In the first session of the Chinese Academy of Chinese Medicinal Herbs Symposium in 1989, Coptis chinensis was identified as Coptis chinensis.
