Safety concerns: Generally considered safe when administered orally within the recommended dosages. Some studies have shown the main alkaloid, berberine, to have toxic effects - however, very large amounts would need to be consumed to activate the toxic effects due to the poor bioavailability of the alkaloid (less than 1%).
