I think I have tried just about everything out there, and what I have found that works and that I feel safe using is blackberry juice. Plain old blackberries work too, but I have a hard time wtih them I don't like tart fruit. someone told me that there were a natural remedy for diarrhea and nausea. (I think raspberries might work too, but I haven't tried them.) I found blackberry cider at a roadside stand on vacation and decided to try it. It is amazing how fast it kicked in! I haven't been able to find it in the grocery store, but there are a few sites on the internet that sell it. I order it online by the case, so I am sure not to run out! But, if you have a country store in your town--check there first, b/c they might have it and the shipping prices can be a bit steep when ordering online.If you are really ambitious, you can try canning your own blackberry juice (I suppose you can do it at home, but I would suggest finding a canning plant or juicer). It is alot of work, but if it is cooked, it has a shelf life of 1-2 years, so it would last you a while.Hope this helps!!
