CanPrev Black Walnut Complex is a nine-herb formula in vegetable capsules, led by black walnut hull, clove, wormwood and quassia. Black Walnut, Wormwood, and Quassia are traditionally used in Herbal Medicine as vermifuges (to expel intestinal worms). It is designed as a short course: the label dose is 2 capsules three times a day, and a bottle of 120 covers 20 days.

A short, structured course
This is not an everyday supplement. The label sets a dose of 6 capsules a day, split across three times, and asks you to consult a health care practitioner for use beyond 2 weeks. Take the capsules between meals, or with food if you want to avoid digestive upset, and 2 hours apart from any medication or other natural health product.
Read the cautions first
This formula carries a long list of cautions, so read them before you buy. It contains walnut, so anyone with a walnut allergy should avoid it. It is not for use during pregnancy or breastfeeding, or by anyone trying to conceive, and the label lists several medications and health conditions where it should not be used, or only with a health care practitioner's advice. The complete cautions are under How to Take.
