Genkent Activated charcoal is a fine black powder that is very absorbent. It is created, or activated, by carbonizing organic matter. Coconut shells are what most of the activated charcoal is made from. This process increases the absorbency of the molecules so that more toxins and impurities can be absorbed.
It is used to soak up harmful or toxic substances that your body can't digest. Activated charcoal can only absorb toxins or chemicals that are still in your stomach and intestines. The charcoal and toxins are then removed from your system when you have a bowel movement.
