Barberry has been used for approximately three thousand years in China and India in the treatment of diarrhea and intestinal infections.  Native Americans used the barberry plant for treating liver conditions.  Barberry contains an alkaloid, berberine, which Is also found in other medicinal herbs such as goldenseal and Oregon grape, and the therapeutic effects of barberry are attributed to its berberine content.
Studies have found that berberine contains properties effective against a wide variety of bacteria, viruses and fungi, and that berberine was more effective in treating some bacteria than a strong antibiotic.  Other studies have found that barberry can kill microorganisms such as staphylococci, streptococci, salmonella, Giardia lamblia, Escherichia coli, shigella and Candida albicans.  The berberine in barberry has also been found to contain antidiarrheal properties and is recommended to stimulate the immune system.
Barberry’s effects include help against cancer, liver problems, kidney problems, coughs, cholera, diarrhea, fever, inflammation, hypertension and tumors.  Barberry is also recommended to increase bile secretions and stimulate the appetite, and it may help in cases of anemia and malnutrition.  It stimulates bile production for liver problems and dilates blood vessels to lower blood pressure.
