Here are some powerful options to remove toxic heavy metals from your intestinal tract: Cilantro: eat half a cup a day of this herb as-is, sprinkled on salads, or in a smoothie. Parsley: eat a quarter cup a day of this herb as-is, sprinkled on salads, or in a smoothie. Zeolite: buy this mineralized clay in liquid form. Spirulina (preferably from Hawaii): if it’s in powder form (which is best for removal of metals from the gut), mix one teaspoon daily into water or a smoothie.
