What are the benefits of activated charcoal? How to use charcoal to detox? Charcoal when heated in presence of a gas to become more porous becomes activated charcoal. Also, called activated carbon, it can trap chemicals because of its porous nature. It is used for various purposes including extraction of metal, purification of air and water, gold purification, medicinal purposes, decaffeination, treatment of sewage, air filters in respirators and gas masks etc. It is popularly used in hospital emergencies especially, to handle drug overdose and poisoning as it binds the toxins on its surface and then eliminates them. Capsules or tablets of activated charcoals are also available as over the counter medicine in many countries for the treatment of various gastric issues.

How Does Activated Charcoal Work?

Activated charcoal has very high levels of microporosity and a larger surface area. These pores adsorb chemicals and toxins i.e. they get bound to the surface of the activated charcoal and then are expelled easily. Activated charcoal is also negatively charged and therefore it easily attracts positively charged toxins toward itself. In cases of some drug or toxin poisoning activated charcoal works by hampering their enteroenteric and enterohepatic circulation.

In a study done on end stage renal disease patients it was seen that activated charcoal supplements were useful in reducing levels of urea and other toxins in their blood.

16. Supplements Treatment Of Candidiasis:

By virtue of its adsorption capacity activated charcoal can serve as a good supplement to any treatment for Candida albicans yeast infections.
