There are two very different health benefits from Aloe vera. Gel from the Aloe leaf has been used for centuries as a topical remedy for minor burns, cuts, and other skin irritations. The second benefit is its laxative effects from internal use of Aloe juice or encapsulated powder.
The active constituents for aloe’s laxative effect are known as anthraquinone glycosides, which are converted by intestinal bacteria into aglycones. The active compounds responsible for aloe’s wound healing properties are likely a combination of several saccharide molecules. Other beneficial effects, especially from high fiber content of the plant, are on cardiac disease risk factors by reducing blood levels of cholesterol, triglycerides and glucose.
Dosage: Laxative - 50-200 mg per day or about 1-3 ounces of aloe gel can be taken by mouth for constipation relief. Aloe juice can also be used as part of a detoxification or cleansing protocol. As topical relief for minor skin irritations, aloe gel can be applied as needed throughout the day.
Side Effects: There are no significant side effects noted with aloe vera as an internal or topical agent, except in rare cases of aloe-latex allergy. Pregnant women, however, should avoid aloe-derived laxatives during pregnancy. However, excess consumption of oral aloe juice products (12-16 ounces per day) may lead to nausea, vomiting, and diarrhea.

16. Aloe vera could exhibit the actions of both antiinflammation and wound healing promotion when applied on a second-degree burn wound. (ANIMAL)
17. Aloe vera influences the wound healing process by enhancing collagen turnover in the wound tissue.
18. Wounds were treated either by topical application or oral administration of Aloe vera to rats and both treatments were found to result in similar effects. (ANIMAL)
19. Aloe vera treatment of wounds in diabetic rats may influence inflammation, fibroplasia, collagen synthesis and maturation, and wound contraction. These effects may be due to the reported hypoglycemic effects of the aloe gel. (ANIMAL)
20. Both topical and oral treatments with Aloe vera were found to have a positive influence on the synthesis of glycosaminoglycans (GAGs) and thereby beneficially modulate wound healing.

34. 5,000 patients on dietary aloe reduced total cholesterol, triglycerides, and blood sugar level in diabetic patients, total lipids and also increased HDL. Clinically there was reduction in the frequency of anginal attacks and gradually, drugs, like verapamil, nifedipine, betablockers and nitrates, were tapered.
