Activated charcoal is a form of carbon that has been processed to create small, low-volume pores, increasing its surface area. This unique structure allows it to adsorb (not absorb) various substances, making it useful in various applications, including water purification and medical treatments. It is often used in emergency medicine to treat certain types of poisoning or overdose by binding to toxins in the stomach. In addition to its medical uses, activated charcoal is also found in beauty products, such as face masks and toothpaste, where it is believed to help remove impurities and whiten teeth. However, while it can be effective in some situations, it is important to use it correctly and consult with a healthcare professional when considering its use for health-related purposes.
