Activated charcoal has been in use for over thousands of years, and has been used to treat a number of things that include medical and health usage.
Regular charcoal and activated charcoal are very identical, with the main difference being that activated charcoal has been created specially for medicinal purposes. It is created by heating regular charcoal with a gas, which causes it to expand and make a porous surface that can capture toxins.
Activated charcoal can chemically bind other substances to itself and absorb quantities thousand times its own weight, which is why even the smallest bit of charcoal can absorb so many toxins. Due to all its pores, it has an extraordinarily large surface area – one cubic inch equals a 150,000 square-foot field!
