Ingredients: 100% pure amargo bark (Quassia amara). No binders, fillers or additives are used. This product is non-irradiated and non-fumigated. This is a wild harvested plant—grown naturally in the Brazilian Amazon without any pesticides or fertilizers.
Traditional Preparation:* The traditional remedy as a digestive aid is 1/2 teaspoon of wood powder infused in one cup of boiling water. This is taken 10-15 minutes before or with meals. Alternatively, 1g in tablets or capsules can be taken two or three times daily on an empty stomach for an internal parasite cleanse. Another remedy calls for 2 teaspoons of wood powder or chips to be soaked in 1 cup of cold water overnight (a cold maceration). This is drunk for internal parasites, gallstones, and digestive disorders, and used externally for lice. For more complete instructions on preparing herbs see the Methods for Preparing Herbal Remedies Page.
