How does it affect diabetes?
Preliminary research suggests that intake of aloe vera juice can help improve blood glucose levels andmay therefore be useful in treating people with diabetes. 
Aloe has also been linked with:
- Decreased blood lipids (fats) in patients with abnormally high levels of these molecules in the blood (e.g. some people with type 2 diabetes ) and/or acute hepatitis (liver disease)
- Decreased swelling and faster healing of wound injuries. Leg wounds and ulcers are common complications of diabetes , and they typically take longer time to heal than in healthy non-diabetic individuals. 
These positive effects are thought to be due to the presence of compounds such as lectins, mannans and anthraquinones.
