Here is what Dr Weil has to say about Aloe Vera and Aloe Vera Juice:
Aloe vera juice, sold in all health-food stores, is intended for internal use. The main use is to help heal ulcers and other irritations of the gastrointestinal tract. In high doses, aloe is an irritant laxative, so if you want it to soothe the lining of your GI tract, you must stay below the laxative dose.
