Activated charcoal is a form of carbon that has been processed to increase its surface area and thus its adsorption capacity. It is made by heating organic materials, such as wood, coconut shells, or coal, in the absence of oxygen. This process creates a porous structure with a high surface area, which allows the charcoal to adsorb a wide variety of molecules.
Activated charcoal has been used for centuries to treat a variety of conditions, including poisoning, diarrhea, and gas. It is also used in water purification and air filtration systems. In recent years, activated charcoal has become increasingly popular as a natural remedy for a variety of health conditions, such as acne, bloating, and high cholesterol.
