Aloe Vera

Although Aloe Vera is a member of the Lily family; it is very cactus-like in its characteristics.

Two produce are made from Aloe Vera plant:
Aloe Vera Juice presents in the cells beneath the surface of the leaves.
Aloe Vera Gel from the fleshy interior of the plant.

Aloe Vera as many properties, those which concern the digestive process are:

Regulating gastrointestinal pH
Improving gastrointestinal motility
Increasing stool specific gravity
Reducing populations of certain fecal microorganisms
Helping to detoxify the bowel.

I recommend taking 1 Tbsp of Aloe Vera gel in your lemon drink each morning.
