Charcoal is a natural product made from wood or other combustible materials, such as coal. It is an amorphous form of carbon that has been used since ancient times for its various properties such as its ability to absorb odors and toxins, its ability to light quickly and remain glowing for extended periods of time, and its efficiency in producing heat. Charcoal can be created through the process of pyrolysis which involves burning material in the absence of oxygen. Its porosity makes it highly effective for filtering water and air, and it has both medicinal and cosmetic applications. Charcoal has proven to be especially beneficial in medical emergencies when ingested or applied topically, as it can absorb a wide range of chemicals, heavy metals, pathogens, and toxins.
