Berberine is an alkaloid found in the barks, leaves, twigs, rhizomes, roots, and/or stems of various plants, such as barberry, Oregon grape, and tree turmeric. Traditionally, berberine has been used as an antimicrobial, antiprotozoal, and antidiarrheal agent in Ayurvedic medicine and traditional Chinese medicine.[1][2][3] Most research in humans has examined berberine’s effects on markers of glycemic control, blood lipids, markers of liver function, and anthropometric parameters in people with metabolic disorders.
