A bit pricy I would say. For that price you can buy a big bottle of charcoal for the whole year :-) Have you ever heard about activated charcoal? I just wrote a post about it and it's cheap. This is about 3,000 years old and cures a lot of diseases and also regulates metabolism, appetite etc. It is good for just about anything. Farma industry doesn't mention it because it can damage them. Check it out!
