It was in 1831 when Professor Touery (in the presence of his colleagues from the French Academy of Medicine) drank a lethal dose of strychnine, and, to their great surprise, survived. He mixed the poison with activated charcoal. Activated Charcoal is a powerful tool for emergency cleansing of the gastrointestinal tract, perhaps the most effective remedy known today. It can be used in cases of poisoning from virtually any toxic substance. Activated charcoal reduces the absorption of poisonous substances up to 60%. Activated charcoal is a sponge-like substance that is made from different carbon-containing substances of natural origin. Activated Charcoal is charcoal that has been treated with oxygen. The treatment results in a highly porous charcoal. It is made at very high temperatures and as a result, activated charcoal is a substance which is almost one hundred percent composed of carbon. The chemical composition of charcoal is very similar to graphite. Useful properties of activated charcoal can be contributed to the huge number of pores and hence activated charcoal exhibits very high absorbent and catalytic properties.
