Black Walnut Supplements

What is black walnut?

Black walnut supplements are made from the hull — the green outer casing around the nut of the black walnut tree (Juglans nigra). The hull has a long history in traditional herbalism, and today it's most commonly used in cleanse-style formulas. It's often combined with other traditional botanicals like wormwood and clove, and comes as capsules or liquid tinctures.

Black walnut forms and combinations

• Hull capsules — black walnut hull in capsule form (e.g. Nature's Way, CanPrev).
• Liquid tinctures — black walnut hull extract in liquid, on its own or in combinations (e.g. St. Francis).
• Cleanse kits & blends — multi-step or multi-herb formulas that pair black walnut with wormwood, clove, and fibre (e.g. New Roots Purge Parasitis).

Things to know

A few things are worth knowing. Black walnut is a tree nut, so anyone with a nut allergy should avoid it. It isn't recommended during pregnancy or breastfeeding. Traditional cleanse formulas are usually taken as a short course rather than long-term, and directions vary between products, so follow the label. If you take medication, have a health condition, or are unsure whether a cleanse is right for you, check with your healthcare practitioner first.
