Activated charcoal is a potent natural antidote used to expel toxins and chemicals from the body, allowing them to be flushed out so the body doesn’t reabsorb them. It’s made from a variety of materials, such as coconut shells or other natural hardwood sources. The nooks and crannies in activated charcoal are created through a burning process, and is then subjected to the activation of an oxidizing gas, such as steam or air, at high temperatures.
