The whole family can use it in brushing their teeth to remove plaque and restore tooth enamel. One girl had not been to the dentist in two years. Only two weeks before her dental appointment she began using the Black Walnut as a tooth polish after brushing. Black Walnut, of which the inner bark, leaves, fruit and unripe husk are used in herbology, is a rich source of the trace mineral chromium and is also high in iodine. The tree grows widely in the western U.S. and Canada.
Herbalists classify it as an astringent because it is rich in tannin, a toning substance.
Historically, the husks have been used since the time of the ancient Greeks to support the intestinal system. Available in capsules and an alcohol-base liquid form. Each capsules contains 500 mg black walnut.
