They sell an even more potent version of these charcoal pills in Japan. And, yeah, it is sold over the counter.I don’t know if activated charcoal will work well at that point but I do know it is absolutely a miracle cure for food poisoning.
I ran out of it and happened to get hit. I couldn’t go to the store because there wasn’t one close enough. I was digging through all my cabinets and found one lone capsule. It let me get to CVS and back. Once I took regular doses the problem was gone. You really need to start taking it when you feel the first symptom.
It works for any kind of gas issue.
