Frequently Asked Questions
What is walnut bark?
Walnut bark is the inner bark of trees in the Juglans genus, most commonly black walnut (Juglans nigra). It contains bioactive compounds including juglone, tannins, and flavonoids, and has been used for centuries in traditional herbalism for digestive support and internal cleansing.
Is walnut bark safe to take daily?
Walnut bark is generally intended for short-term use (2-4 weeks) rather than continuous daily supplementation, due to the cytotoxic potential of juglone at sustained high doses. It should be used under the guidance of a qualified herbalist or healthcare practitioner, and is contraindicated during pregnancy, lactation, and in those with liver or kidney conditions.
What are the main benefits of walnut bark?
Walnut bark is traditionally valued for its antiparasitic, digestive, and liver-supportive properties.
