The ability of aloe-vera to treat burns is well known, making it a common plant to grow in a kitchen window for emergency treatment of minor burns. However, aloe vera gel, found in the inner meaty part of the thick leaves, has many other health benefits as well when taken orally. Gel capsules are a convenient way to take a regulated dose of aloe vera. Always check with your health care provider before taking aloe vera gel capsules.

Digestive Problems

Aloe vera gel capsules may be used to treat digestive problems ranging from heartburn and indigestion to constipation or diarrhea. All4NaturalHealth.com reports that the fatty acids found in aloe vera aid in proper functioning of the stomach, intestines and colon. Regular use of aloe vera can help the body stay healthy by regulating the digestive system, according to SacredSourceNutrition.com. Aloe can help regulate intestinal bacteria, eliminate parasites and treat irritable bowel syndrome. Use caution when taking aloe vera internally, cautions the University of Maryland Medical Center, since it can cause severe abdominal cramps. It may cause uterine contractions, and you should avoid taking aloe internally if you are pregnant.

Cancer Prevention

Studies reported by MedlinePlus.com indicates that taking aloe vera orally may help prevent some types of cancer, including lung cancer. While the results of early studies are promising, more research needs to be completed to substantiate the claims.

Nutrient Absorption

Taking aloe vera orally can improve nutrient absorption in the intestinal tract, according to All4NaturalHealth.com. It also improves bile production and can help control fungus infections and candida.

Strengthen Immune System

Aloe vera is rich in vitamins, minerals and enzymes that strengthen your immune system. Acemannan is a newly discovered polysaccharide compound in aloe gel that can build natural resistance by boosting T-lymphocyte cells. It is currently approved in a prepared, pure form for veterinary use in treating tumors in dogs and cats, according to Drugs.com.
