How Does Activated Charcoal Work?

Activated charcoal is often seen as a miracle substance, known for treating poisoning and filtering water. It's used in various products like cosmetics and teeth whiteners. However, its health benefits are often overstated. Activated charcoal is made by treating charcoal with heat and chemicals, creating a large surface area for adsorption. This process allows it to trap molecules, especially those containing carbon, through Van der Waals forces. While effective for certain poisons and toxins, claims about its ability to whiten teeth, reduce gas, or cure hangovers lack strong evidence. It's safe to consume but not a magical health solution.
