Black Walnut Tincture

Juglans Nigra, commonly known as black walnut, is a large hardwood tree native to the east coast of North America as well as Asia. It was imported to Europe before the common era.


Black Walnut has been used in herbal medicine for centuries as a very effective anti-parasitic helping to kill and expel helminths (worms) as well as other parasites. It is also a powerful anti-fungal, including against candida albicans (1)Juglone is one of its active constituents and has been shown to be as effective as zinc undecylenate in treating fungal issues. It also exhibits anti-bacterial properties against Staph. aureus and other species, as well as having anti-neoplastic activity (2, 7). Juglans has successfully treated various forms of herpes and other virus (3-6). Anecdotally, Dr. Michael Lebowitz reported a case back in the 1980s of a 2-year-old with a positive c. difficile stool test unresponsive to the prescription given to her. She was exhibiting severe diarrhea. Juglans nigra tincture cleared the symptoms within a few days and a follow up test was negative. Dr. Lebowitz also had a 2nd similar case. We do not recommend forgoing allopathic treatment for this type of infection, but found this interesting to report (8)

Dosage: 10-30 drops 3x/day.

Contraindications: Do not use if pregnant or breastfeeding


Our tincture is extracted with organic cane alcohol which is then boiled off (as much as possible while retaining potency) and then organic glycerin is added.

Most tinctures on the market are extracted by non-organic grain-based alcohol (many from GMO corn ethanol).  Supreme Nutrition products has decided to manufacture a small number of tinctures. While in general we prefer dried whole herb, our tinctures can also be effectively used. The main reason we decided on these is we wanted a small line of antimicrobials for children too small to swallow pills that would cover many bases. Our first product of this type, elderberry, is primarily an anti-viral and black walnut is primarily antiparasitic. They are also effective for adults.
