Black walnut hulls contain a large amount of chemicals called tannins. Tannins absorb substances in the stomach and intestines. Taking black walnut along with medications taken by mouth can decrease how much medicine your body absorbs, and decrease the effectiveness of your medicine. To prevent this interaction, take black walnut at least one hour after medications you take by mouth.
