Black walnut hull

Tier 3 — weak evidence · Antimicrobial · Antiparasitic · Gut

Contains juglone, a compound with antimicrobial and antiparasitic activity in lab studies. Popular in naturopathic antiparasitic protocols alongside wormwood and cloves, but no human clinical trial has validated this use. Juglone can be irritating to the digestive tract and may stain teeth. May interact with blood thinners and thyroid medications. Evidence is entirely traditional and preclinical. Not recommended without practitioner guidance.

Dose: No evidence-based dose established; typically 500 mg hull extract in traditional protocols; safety data limited
