      Tannins are a group of unrelated chemicals that give plants an astringent taste. Herbs containing high amounts of tannins, such as green tea (Camellia sinensis), black tea, uva ursi (Arctostaphylos uva-ursi), black walnut (Juglans nigra),red raspberry (Rubus idaeus),oak (Quercus spp.), and witch hazel (Hamamelis virginiana), may interfere with the absorption of atropine taken by mouth.
