Rating (out of 5): 3

Coptis chinensis (Huang Lian) is a well-known herb in Traditional Chinese Medicine (TCM), valued for its bitter taste and cold properties. In TCM theory, it is primarily used to "clear heat" and "dry dampness"—conditions often associated with dysfunction of the Spleen body system. According to TCM, the Spleen plays a central role in digestion and the transformation and transportation of nutrients and fluids. When "dampness" impairs the Spleen, symptoms such as poor appetite, loose stools, and fatigue may occur. Coptis chinensis is traditionally used in herbal formulas to combat these symptoms by draining dampness and supporting Spleen function.

Modern pharmacological studies have identified berberine as a major active compound in Coptis chinensis, which has demonstrated antimicrobial, anti-inflammatory, and metabolic effects. Some research suggests berberine may improve glucose metabolism and gut health, but these findings are not directly linked to TCM concepts of Spleen support. Overall, while there is strong historical and cultural precedent for using Coptis chinensis to support the Spleen system in the context of TCM, scientific validation specific to the TCM concept of "Spleen support" is limited. Thus, the primary justification remains traditional, with a moderate evidence rating reflecting its established role in TCM and some emerging, though indirect, scientific insights.
