[Craig Campbell]

Craig Campbell asked the Naked Scientists:
   
Could you please tell me if there is any truth in this statement:

"Negative ions found in activated bamboo charcoal has health benefits as in better blood circulation"

I cannot find an answerand would like to know if its just a lot of hoo ha.

Regards

Craig

What do you think?

Sounds like nonsense to me.

Charcoal is used in cases of poisoning ...

While activated carbon is useful in an acute poisoning situation, it has been shown to not be effective in long term accumulation of toxins, such as with the use of toxic herbicides
