I trust charcoal.
I use it  whenever i am bloated. I love it, because when I take it after like 2 minutes I feel great.<br />When I was young every summer we want to my grandmas house for vacation. It was a tradition to hike to the mountain to the special spring source. We would take with us charcoal. We would drop it in the water, wait little bit ,  then drink.
