The bitter taste of Rhizoma Coptidis is well known to women and children, but people are "dumb to eat Rhizoma Coptidis, but they can't tell the bitter taste", which means that people who have eaten Rhizoma Coptidis will never forget this bitter taste, so the name of Rhizoma Coptidis is "William", which is not delicious. If it weren't for the unique efficacy of Rhizoma Coptidis, people would have forgotten the importance of this bitter cold.
What is the special curative effect of coptis chinensis?
Shennong Herbal Classic is the earliest classic of traditional Chinese medicine that records the curative effect of Rhizoma Coptidis. According to the book, Coptis chinensis is responsible for "diarrhea of intestinal abdominal pain, swelling and pain of vulva". Why is Rhizoma Coptidis, which tastes so ordinary and bitter, used to treat abdominal pain and diarrhea? This will start with the unique medicinal effects of coptis chinensis.
Coptis chinensis is bitter and cold, and can enter the meridians such as heart meridian, spleen, stomach gallbladder and large intestine. It is an important drug for clearing heat and eliminating dampness. Symptoms such as bowel sounds, abdominal pain and diarrhea are mostly related to damp-heat syndrome of large intestine caused by damp-heat in middle energizer, damp-heat along gallbladder meridian and straight down large intestine meridian. Damp heat blocks middle energizer, leading to abdominal pain and vomiting. Modern medicine has found that berberine and coptisine in Rhizoma Coptidis have good bacteriostatic effect on Shigella, which explains why Rhizoma Coptidis can treat damp-heat downward flow, damp-heat diarrhea and abdominal pain.
As the saying goes, "all kinds of red heat belong to fire" and "all kinds of itching sores belong to heart". According to the characteristics of meridian tropism and bitter cold, heat-clearing and dampness-drying of Rhizoma Coptidis, it is found that Rhizoma Coptidis can clear heat and reduce fire in the heart meridian and reduce heart fire, which is an important Chinese medicine for clearing heat and clearing heart fire. Huanglian Jiedu Decoction, which was originally created in the Secret Recipe of Outer Taiwan, reused Huanglian to clear heart and reduce fire, and has good hemostatic and heat-clearing effects on patients with high fever, lethargy, hematemesis and bleeding.
In addition, Coptis chinensis also has good effects of clearing away heat, reducing fire and treating sores, ulcers and furuncles. Because Rhizoma Coptidis can enter the heart meridian and stomach meridian, it is necessary to clear the heart and reduce the fire if the heart fire is excessive, and the toothache symptoms caused by stomach fire must be treated with Rhizoma Coptidis, and the magical effect of "Rhizoma Coptidis Decoction" in Puji Fang in treating furuncle and gingival swelling and pain is the best evidence.
