The hull of the black walnut (Juglans nigra) has been used in herbal medicine for centuries, particularly by Native American and European herbalists. It contains juglone, tannins, and iodine—compounds known for their strong antimicrobial, antifungal, and antiparasitic effects.

Black walnut works by:

• Creating an intestinal environment that is hostile to parasites, worms, and pathogenic fungi.

• Helping break down and remove biofilms—protective layers that harmful microbes create to shield themselves from the immune system.

• Reducing yeast overgrowth (including Candida albicans) by altering gut pH and starving fungal colonies.

• Providing astringent tannins that help tone and strengthen the intestinal wall.

Because black walnut is rich in antioxidants, it also helps counteract oxidative stress that can occur during detoxification, further protecting delicate gut tissues.

The Synergy – Binding + Purging
When combined with bentonite clay, the two work in sequence:

1. Black walnut helps dislodge and weaken harmful organisms and biofilms, disrupting their hold on the intestinal lining.

2. Bentonite clay binds to these unwanted materials, trapping them within its structure.

3. The body then removes them naturally through bowel movements, reducing the chance of reabsorption (a common problem in incomplete cleanses).

This dual action not only promotes a cleaner, healthier digestive tract but also supports a stronger immune system, improved nutrient absorption, and reduced inflammation. By eliminating toxins and parasites while simultaneously protecting and toning gut tissue, this combination plays a pivotal role in the effectiveness of the Flush GBI protocol.
