Black walnut (Juglans nigra) is an excellent herb used both externally and internally to help fight fungus, worms, and all parasites. Black walnut is a very useful plant because almost all parts of this plant are used—and all parts have different purposes.
The rinds or hulls of the black walnut are most specifically utilized for antifungal properties. Black walnut hulls will usually come in a capsule form, or you may use the powder or liquid extract of the ground hulls for external applications. Black walnut bark taken internally may have a laxative effect, but can rid the bowel of parasites and fungus at the same time.
To fight fungus overgrowth and parasites use garlic and black walnut together—these two herbs make a good pair for this purpose. You have bacteria in your body all the time; fungus or bacteria overgrowth can occur only when your internal flora is out of balance. This is why supplementing with the good intestinal flora is helpful when fighting internal fungus infections or parasites.
Pau d’arco is another herb well-known for its fungus-fighting ability. Although this tree grows in a tropical area, its bark remains fungus-free. Drink a cup of pau d’arco tea each night along with taking your garlic and black walnut supplements to fight Candida, yeast infections, parasite infestations, and fungal infections. You can use tea tree oil as a topical application for athlete’s foot and ring worm; apply it directly to the area once in the morning and once in the evening. I have used a Q-tip dipped in tea tree oil for cleaning my ears to kill off an itchy fungal growth on my ear drum—in 10 days the fungus was gone. This is also effective if you dampen a cotton ball with tea tree oil and place gently in each ear. The fumes from the tea tree are effective in destroying fungus in the ear canal.
