I gave Aloe Vera a try, with violent consequences! It produced dreadful cramps and diahrea. It is very good for constipation, and does work for many, but if you end up with cramps and diahrea, it could well be the Aloe Vera. I actually have inflammation in the small intestine (diagnosed as Crohns). I had read about Aloe being very good for this, so I was disappointed I had such a severe reaction!
