MH asks: “Do you know the origin of using Bentonite Clay and Charcoal capsules as a way of cleansing your body of toxins, impurities, and heavy metals? Also, do you know if this therapy is safe to do? Supposedly they both absorb heavy metals and are carried out of one’s digestive system. An environmental Dr. is advising me to do this. I wanted to make sure it’s in line with Church teaching and is safe to do.”
