Requa Activated Charcoal Tablets Produced to medical standards, the activated charcoal in these tablets is the purest form of carbon, the building-block element of the body, available today. Activated Charcoal has also been used for centuries as a natural internal detoxifier and is commonly used to help cleanse the body of unwanted materials. Imbalance of these toxins or other substances can lead to putrification and gas or excess flatus.
