1. Whitening Teeth

Using activated charcoal offers many oral hygiene benefits, including the prevention of cavities, bad breath and gum disease. It is also highly effective for whitening teeth, as it absorbs plaque and stain-causing deposits.

To get bright pearly whites, simply mix a small amount of activated charcoal (approximately 1-2 emptied capsules) with water until it forms a thick paste, then brush or apply directly onto the teeth. Wait three minutes and then rinse. While a special toothbrush is not necessary for this treatment, the charcoal will likely cause discoloration of the bristles, so it may be worth keeping a special one just for this purpose.

2. Relieving Gas and Bloating

Activated charcoal’s ability to bind gas-causing food byproducts within the digestive system makes it an effective treatment for indigestion, acid reflux and bloat. In fact, a study published in the American Journal of Gastroenterology found that activated charcoal significantly reduced symptoms of bloating and abdominal cramps caused by gas after eating.

To aid with this discomfort, activated charcoal can be taken in pill, liquid or powder form. To prevent depletion of valuable vitamins and minerals, Best Health magazine says that it should be taken between meals when the stomach is emptier.

3. Treating Poisoning from Alcohol or Other Toxins

The powder form of activated charcoal, when mixed with a non-acidic liquid, can be beneficial for treating poisonings caused by substances like alcohol, iron tablets, cyanide and lithium. The negative charge of activated charcoal acts like a magnet, to which the positive charge of toxins will become bound.

Some studies have found that when consumed at the same time as alcohol, activated charcoal can significantly reduce blood alcohol concentrations—helping to prevent hangovers. More conclusive research is needed, however.
