Of course, oil pulling is just one of a number of natural at-home health practices that more and more folks have been talking about. Another you may be hearing more about these days is activated charcoal. Claims about it range from instant teeth whitening to a good digestive cleanse.
But what do we know about it really?
We’re Not Talking Briquettes
When you hear “charcoal,” your thoughts probably turn to the stuff you might fuel your barbecue grill with. Activated charcoal has been treated with oxygen. This makes it more porous, which makes it more absorbent.
This is why it’s been a go-to treatment for overdose or poisoning. It absorbs toxins so they can’t be absorbed into the stomach.
A classic and frequently cited early demonstration with charcoal was the ingestion of a lethal dose of strychnine mixed with charcoal by Tovery before the 1831 French Academy of Medicine. Tovery suffered no ill effects from the strychnine because of the simultaneous ingestion of charcoal. Similarly, the American physician Hort, by administering oral charcoal, reportedly saved the life of a patient in 1834 who ingested mercury bichloride.
When used for acute poisoning, activated charcoal is given in extremely large doses. But in small doses, it can be used as a supplement.
Activated charcoal comes in a powder, liquid, or pill/capsule form. The powder is typically mixed with water for topical applications on teeth or as a face mask. The liquid and pill forms are typically ingested in small doses (along with large amounts of water) to help with digestion or to remove harmful toxins like mold from the body (yep, mold – in the body).
What’s Charcoal Good For?
A literature review in the Natural Medicine Journal found good or still unclear scientific evidence for activated charcoal’s use in treating conditions ranging from diarrhea to kidney disease. The author also mentions a range of other uses of the supplement based on tradition, hypotheses, or limited research. These include
Aging, asthma, blood disorders, blood purifier, bronchial asthma, deodorant, disease diagnosis, inflammatory skin conditions, irritable bowel syndrome, liver disorders, metabolic disorders, ulcerative colitis.
But it has its uses in dentistry, as well. For instance, mercury-safe dentists may give patients charcoal before and after removing a patient’s amalgam fillings to protect against any mercury that may accidentally be swallowed during the procedures. (Others use chlorella, a single-celled micro-algae that’s also effective for detox.)
It’s also something that some of our patients may be recommended as part of their formal detox regimen, as it binds heavy metals so well.
Increasingly, we also see people using it at home for teeth whitening – as has been done throughout history. In addition to removing stains, it may also improve oral pH and help keep oral flora in balance (supporting the helpful bacteria, fighting the harmful). Because of this, it’s also said to help tame bad breath, as well.
That said, if you have crowns, veneers, or other tooth-colored dental work, using charcoal can stain such restorations terribly. If you have any, cleaning with charcoal is not for you.
And if you’re thinking about taking activated charcoal as a supplement? Do consult a qualified integrative or naturopathic practitioner before you begin – particularly if you are taking other supplements or medications (including homeopathic ones), or if you are currently being treated for any health conditions. Even supplements can have bad interactions or may trigger troubling side effects.
