Black Walnut capsules contain a blend of herbs traditionally used in herbal medicine to help relieve digestive upset. Black walnut, quassia, wormwood, and gentian root all contain extremely bitter components, including tannins, quassin, absinthin, and amogentin. These bitter components stimulate the nerves on the taste buds to increase the release of saliva and gastric juices, aiding digestion. Bitter components may also bind to receptors on endocrine cells in the gastrointestinal tract and pancreas, leading to the secretion of the peptide hormone cholecystokinin. In turn, bile salts and pancreatic digestive enzymes are released, which increases gastric motility. Gentian root and quassia may help relieve indigestion by enhancing prostaglandin-facilitated cytoprotection in the gastric membrane; prostaglandins stimulate the release of mucus and sodium bicarbonate in the stomach. Quassia, black walnut, and pumpkin seed are also traditionally used in herbal medicine as anthelmintics (to help expel parasitic worms).
