As crazy as it sounds, this one simple home remedy can really whiten teeth (and help with gum disease) and is also very effective against food poisoning and other types of internal toxins.
I used Activated Charcoal a few months ago when I had an awful bout of food poisoning, and it worked wonders! This is actually the substance that many hospitals have on hand and use when patients have ingested toxins or when they pump patients’ stomachs. It is available as a loose powder and in capsule form (see notes below!)
Activated charcoal is a highly absorbent substance. It removes toxins when they adhere to the surface of the charcoal. It is not absorbed by the body, but passes through the GI system, so chemicals and toxins adhere to it, pass through the body and are expelled by the digestive system.
In the 1800s, two men took lethal doses of poisons (including arsenic) and survived without harm… their secret: they mixed the toxins with activated charcoal powder. (Stating the obvious: do not try to repeat these experiments!)
Activated charcoal is extremely effective at pulling toxins from household chemicals, ingested medicines, and other toxins from the body, especially when taken within 30 minutes of ingestion. For this reason, it is a great first treatment for any kind of poisoning, but should not be taken within several hours of medications (or even vitamins) that DO need to be absorbed.
There is even some evidence that activated charcoal is helpful both before and after alcohol consumption to lessen the amount that is absorbed by the body.
Even mainstream medical sites are on board with the benefits of using activated charcoal for a poison remedy.
Should you ever need to use activated charcoal on yourself of a child for poisoning, use as soon as possible and call a poison control center or go to the emergency room as well to make sure the poison has been fully removed!
