Way back in 1984 it was discovered that drinking Aloe Vera juice seemed to help people a great deal, even to the point where they became symptom free. The actual component that makes it work is a sugar called mannose.
This same sugar is also found is great abundance in oat bran.
If one drinks the Aloe juice be certain that is has been stabilized. otherwise the mannose may be destroyed by naturally accruing enzymes.
Look in the bottle for the amount of active polysaccarhides. Pollysaccarhides is just another name for sugars.
