In Oriental medicine the roots bright yellow color suggest the herbs affinity with treating conditions of the Spleen and Stomach. Both these systems are identified with the color yellow and the Earth Element in the ancient Five Phase Theory of medicine. As a bitter yellow root it is noted for relieving Damp Heat, a condition that can, among other functions, impede proper digestion. From a western perspective, it is thought to reduce acids in the stomach that can cause digestive issues.
Coptis contains the constituent berberine, well known for its immune enhancing and antimicrobial properties. Berberine has been studied for its ability to help prevent obesity, fatty liver disease, and lowering cholesterol levels by activating AMPK (Adenosine 5’ monophosphate-activated protein kinase (AMPK) is an enzyme that plays an important role in the bodies ability to consume and produce energy.)
Coptis is used to prevent parasitic infections caused by leishmaniasis and trichomoniasis.
Coptis is often combined with other herbs, in order to treat Damp Heat anywhere in the body. This includes vaginal ulcerations, dizziness, epigastric discomfort, poor digestion, palpitations, diarrhea, dysentery, insomnia and other symptoms associated with Damp Heat.
The herb can also be dry-fried to help it enter the blood and warm its normally cold properties. Ginger-frying the herb will also warm the herb and make it easier on the stomach while helping to stop vomiting. Coptis can also be taken with fresh ginger to help counter the herbs bitter flavor. Recommended dose is 1 to 9 g of the dried roots or rhizomes.
While the roots can be harvested in the spring or fall, the roots harvested in the fall are considered superior.
Coptis japonica is the species that is native to Japan.
The threadlike yellow rhizomes are also used as a dye, especially for wool.
