Product Overview
Fresh Green Black Walnut Extract is derived from the unripe, still-green outer hulls of the black walnut tree (Juglans nigra), harvested before the hull darkens and split. The green hulls are naturally rich in tannins, juglone, and other polyphenolic compounds, and have a long history of use in traditional Western and folk herbalism, particularly for digestive and cleansing routines.
To capture the hull's naturally occurring compounds while they are freshest, the plant material is typically tinctured shortly after harvest rather than dried first — a process reflected in the "fresh" designation. The result is a dark, astringent liquid extract that private label brands can standardize, dilute, and bottle for consumers who prefer traditional, plant-based approaches to seasonal detox and digestive support.’
How Brands Use Fresh Green Black Walnut Extract
- Formulated as a stand-alone liquid tincture for dropper-bottle detox and cleanse lines
- Blended into multi-herb digestive or parasite-cleanse formulas alongside wormwood, clove, or other traditional botanicals
- Offered in glycerin-based (alcohol-free) versions for brands targeting consumers who avoid alcohol tinctures
- Positioned within seasonal “cleanse kit” or 30-day reset programs sold by wellness and functional-medicine brands
Because it is sold almost exclusively as a liquid extract, Fresh Green Black Walnut is a straightforward SKU for private label catalogs: brands typically request a specified hull-to-menstruum ratio (such as 1:2 or 1:5), choice of alcohol or vegetable glycerin base, and bottle size and dropper configuration. Buyers frequently pair it with a companion product — clove or wormwood extract, for example — to round out a cleanse protocol under one label.
Health Genesis Corporation formulates and bottles Fresh Green Black Walnut Extract at our FDA-registered, GMP-certified, NSF-certified facility in Davie, Florida, where our family-owned team has been sourcing and manufacturing herbal extracts for over 25 years. We work with low minimum order quantities so smaller and emerging cleanse-category brands can launch without overcommitting to inventory, and our in-house design team can build private label bottle artwork and cartons to match your brand.
Is Fresh Green Black Walnut Extract available in an alcohol-free version?
Yes. We can formulate this extract using a vegetable glycerin base instead of grain alcohol for brands that want an alcohol-free tincture, though extraction ratios may differ slightly between the two menstruums.

Our MOQs for liquid herbal extracts like this one are kept low specifically to support new and growing supplement brands — contact our team for current case-pack minimums for your target bottle size.
