Deficiency of spleen and stomach: why is there coptis chinensis in the medicine prescribed by the doctor?

Coptis chinensis tastes bitter and cold, and is used for damp-heat syndrome or heat accumulation syndrome of middle-upper jiao. The "old Chinese doctor" may prescribe Rhizoma Coptidis for you for two reasons. First, the course of disease is long, and there is a tendency for cold to turn to heat for a long time; Second, the price of Coptis chinensis is a bit expensive because of the doctor's economic considerations. Of course, if you are an apprentice, you may take it for granted to prescribe Rhizoma Coptidis to achieve the "anti-inflammatory" effect.
