The Romans gave this special type of walnut the name "The Imperial Nut" because of its impressive health benefits. Equally impressive are the benefits of its fresh hull (outer shell), harvested in its green state before it blackens, when at its most potent.
Fresh (green) Black Walnut hulls contain powerful antiparasitic and antifungal compounds including juglone, which is highly effective at ridding the intestinal tract of parasites including giardia, blastocystis, pinworms, and amoebas. It is also a powerful antifungal against Candida and other fungal infections such as athletes' foot, jock itch, and ringworm.
Black Walnut can be used preventatively if one is traveling to an area where parasites are commonly encountered; begin taking Black Walnut extract a few days prior to departure and maintain for the entire duration of the trip. Treatment should be continued for at least one month, since the parasite can be present in various stages of maturity, from egg to adult. Prolonged use beyond a few weeks at a time, however, is not recommended.
Common symptoms of intestinal parasites include diarrhea, gas or bloating, nausea or vomiting, stomach pain or tenderness, fatigue or weakness, weight loss and presence of worms in stool.
