I once used a bottle of bitters from my local health food store and found that they stained my teeth quite badly. Do you know what may have caused that? It had dandelion root, meadowsweet, gentian and cinnamon bark.
Also, do the Gallexier bitters you recommended have any berberine herbs or stimulant laxatives? The ingredients are:
