I highly recommend activated charcoal when traveling. It absorbs toxins.
Really not sure if it can help with water issues as that is parasite related (I think) but it is a miracle cure for food poisoning. However it does absorb other meds you take with it...as that is it’s purpose.

That’s why I was so healthy growing up. My mother used the smoke alarm as a kitchen timer!
Seriously though, we couldn’t use a smoke alarm as we cooked year round on a wood fired cook stove. Lots of charcoal as temperature control was difficult.
