Is it true that cabbage juice help with gastritis?

No: No - but it sure can render you flatulent...

Yes! Proven 4 ulcers: Research studies done in the 1950's at stanford medical school confirmed the effectiveness of this old folk remedy for gastric & peptic ulcers. Many thousands have successfully used cabbage juice for ulcers. I have not seen research on gastritis but it is almost certain to help this too. Many advise adding carrot juice for flavor.
