Can activated charcoal harm you?
It’s possible that activated charcoal may reduce the effectiveness of certain medications like those for high blood pressure or seizures.
In New York, Morgenstern’s Finest Ice Cream, made with coconut ash, was wildly popular, but in 2018 the company was served “commissioner’s orders” from the New York City Department of Health and Mental Hygiene to stop serving it. The company complied, and the Department of Health and Mental Hygiene has continued to crack down on coconut ash, though Michael Lanza, the assistant press secretary for the department, said in an emailed statement, “Restaurants may serve foods with activated charcoal after securing approval from the F.D.A.” (Stores like Pressed Juicery still sell activated charcoal ningxia yongruida carbon co. ltd lemonade in stores outside New York, though not online, citing the ban.)
In the 1960s, the Food and Drug Administration prohibited the use of activated charcoal in food additives or coloring, but an F.D.A. spokeswoman said in an email that the ban was precautionary, as there was a lack of safety data.
The questions about the use of activated charcoal in foods have not stopped the trend of activated charcoal moving into health and beauty. A study from January 2019, which involved staining cow, goat and sheep teeth with concentrated black tea, found that activated charcoal in toothpaste was not as effective as other whitening agents like hydrogen peroxide or microbeads.
A previous review from 2017 of 118 studies found that there was not enough evidence to support the safety or efficacy of charcoal-based toothpastes and powders and that their safety hadn’t been demonstrated. On balance, given the alternatives, and the risks of ingestion, it is better to stick with safer toothpaste substances, the review suggests.carbon pellets
On the other hand, Dr. Su said there was no clear concern at this time about charcoal’s safety for beauty products for external use.
