After drinking untreated questionable water, crush (cold) charcoal from your campfire or woodburning fire place/stove (black bits, avoid white ash) into a powder, the finer the better. Man-made briquettes should be avoided, these often contain petroleum accelerants. Mix your ground powder with water creating a "charcoal tea". A bandanna or piece of clothing can be used to strain larger chunks and drink.
Charcoal has been used for millennia to calm upset stomachs and absorb ingested toxins. Having a bottle (purchased from your local health food store) on hand, is an inexpensive, safe, non-perishable method to combat stomach aches and pains.
