I finally had great success using Redmond white clay. 1 teaspoon to 1 tablespoon in 1/2c-1c of water before bed. After a month I felt free and clean at last. I realize the problem may require this protocol or something close to it for the rest of my life. The clay doesn't taste bad. It doesn't taste like anything really. Not good or bad. I also take a spoonful of crushed Garlic whenever I feel the need. That quiets them down. I often also take a large capsule of liquid Yucca extract every day. It tastes too strong and bitter, like molasses without the sugar, so I drip it into a capsule. Yucca seems to work like an internal soap. And a Tablespoonful of food grade Aloe Vera Gel first thing in the morning - that seems to kill parasites too. But I believe it's the clay that kills the most and saved my life and sanity. I tried all the herbs and Male Fern was the best but they all have side effects and danger. Nothing works better than clay for me.
