As reported in Organic Facts – in “21 Surprising Benefits of Aloe” – one benefit is cardiovascular function:
“Aloe vera extract accelerates the supply of blood and purifies it at the same time. This blood accelerates the delivery of oxygen to the organs in the body, thereby maximizing their functionality. Organs like the brain and heart need oxygen that is supported by this purified blood. Therefore, aloe vera indirectly keeps the blood fresh and rich in oxygen to serve these purposes perfectly.”
“Aloe vera gel, when used internally, automatically improves the blood quality and thus helps in re-balancing the other components in your blood like cholesterol and glucose. It effectively lowers cholesterol and total triglyceride content. Blueberries are also powerful, cholesterol-lowering agents, thus you can imagine how great a natural remedy it can be if you combine blueberries and aloe vera.”
