Origin & History
Black Walnut (Juglans nigra) is a deciduous tree native to the temperate forests of Eastern and Central North America, particularly the United States and Canada. Its potent seeds and hulls are revered for a rich profile of bioactive compounds. In functional nutrition, it is highly valued for its antiparasitic, antimicrobial, and digestive-supporting properties.
“Black Walnut has been historically revered in Native American, Appalachian, and European herbal traditions as a powerful anthelmintic and blood purifier. It was traditionally used in seasonal cleansing rituals and gut-healing tonics for intestinal cleansing, skin detoxification, and immune strength.”Traditional Medicine

Frequently Asked Questions
What is Black Walnut?
Black Walnut (Juglans nigra) is a North American tree whose nuts and hulls contain potent bioactive compounds, particularly juglone and ellagitannins. It has been used for centuries in traditional medicine for antiparasitic, antimicrobial, and digestive support purposes.
What is the recommended dosage and is it safe?
Typical supplemental dosage is 500-1,000 mg of standardized extract daily. Antiparasitic protocols may use higher doses for limited periods under practitioner supervision. Juglone is cytotoxic at high concentrations, so long-term or high-dose use is not recommended. Avoid if pregnant, nursing, or allergic to tree nuts, and consult a healthcare provider if taking blood thinners or diabetes medications.
What are the main benefits of Black Walnut?
Black Walnut is primarily valued for its antimicrobial and antiparasitic properties, supported by in vitro and animal research. It also provides antioxidant polyphenols (ellagitannins) that support cardiovascular and cognitive health. However, most evidence comes from preclinical studies, and robust human clinical trials are still needed.
