Hi my name is Stella Metsovas, and today we're going to be talking about black walnut hull, the benefits and its side effects. Black walnut hull actually comes from the beautiful black walnut tree. People use the outer covering of the nut, the hull to make the medicine most commonly used in digestive issues like parasites and you don't want those. According to WebMD, black walnut might be safe for most people when taken by mouth for the short term. It is not known what the possible side effects from long term usage could be. Black walnut hulls contain a large amount of chemicals called tannins. Tannins actually absorb substances in the stomach and intestines. Taking black walnut along with medications that are taken by mouth can decrease how much medicine your body absorbs and actually decrease the effectiveness of your medicine. To prevent this interaction, take black walnut at least one hour after medications you take by mouth and as always and I mean always, check your vitamin interactions with your prescribed medications.
