Phellodendron Amurense Bark Extract WHAT IT DOES
Phellodendron bark is bitter in taste and cold in action. It reduces inflammation and dampness, especially from the lower parts of the body. It has broad-spectrum anti-bacterial and anti-viral activity.
"Huang" means yellow in Chinese, and phellodendron bark is one of the "three huangs, " or bright yellow plants used for treating inflammation and infection (the other two are scute root and coptis rhizome).
The yellow color comes from an alkaloid called berberine, a substance that is slightly-to-mildly toxic in pure form, which is why it is not recommended for use in pregnancy.
