Does cabbage, celery, & apple, juice good for ulcer?

Duodenal ulcers are: Caused by bacteria. So if you know you have one, no diet is going to help unless you get rid these bacteria. If all you have is indigestion, then you can try different diet. But cabbage, celery and apple juice are probably not going to help your digestion. Try taking Prilosec or prevacid, alternatively zantac (ranitidine) or tagamet. These will reduce your stomach acid.
