Numerous studies worldwide indicate that it is a general tonic for the immune system, helping it to fight illness of all kinds. Various research studies are underway to explore the potential of the components to boost immunity and combat the HIV virus, and to treat certain types of cancer (particularly leukemia). It may even have a role to play in managing diabetes.
Over 200 worldwide scientific research papers have been published on the effects. The three main categories of research include anti-inflammatory, anti- bacterial, and anti-viral actions of the plant. The juice is said to soothe digestive tract irritations such as colitis, ulcers and irritable bowel syndrome. It's ability to encourage the release of pepsin (a gastric juice enzyme necessary for digestion) when the stomach is full is a possible reason for its ulcer-healing effects (Journal of the American Osteopathic Society, 1963, vol.62). In one study, oral use for six months helped mitigate asthma symptoms in almost half of the participants. Eleven of twenty-seven patients studied who drank Aloe reported feeling better at the end of the study. Researchers think that results might be due to stimulation of the immune system, as well as naturally occurring anti-inflammatory agents in the plant.
In 1994, the US Food and Drug Administration approved Aloe vera for the treatment of HIV. On-going studies worldwide show that taken in highly concentrated doses can stimulate the production of white blood cells that may help fight viruses and also tumours.
