Over the centuries the black walnut tree has been prized by herbalists who value its bark, leaves and green hulls of the nuts to maintain good health. Black walnuts are thought to deliver compounds that play a role in general health and wellness. Liquid extracts work faster and more completely than other forms of supplementation. There are no pills to swallow, no herbs to press, or tea to steep. Plus, liquid nutrients are absorbed quickly, so they get to work right away. What's more, liquid extracts preserve active constituents and have a very long shelf life. They are also the ultimate in convenience - just add them to water, tea, or juice and enjoy a tasty, nutritious boost at home, work, or on-the-go. Our black walnut green hulls liquid extract is packaged in a brown, light-resistant bottle with easy-to-use dropper. These statements have not been evaluated by the food and drug administration.
