Just want to share that I've got an ulcer, too. I had been using aloe vera straight from the leaf. Just cut off 2 inches, (the leaves are big!) peel it down to just the clear gel inside, pop it in a blender with the juice of a lime or lemon, 5 times the amount of juice in water, some sweetener and drink it down first thing in the morning and last thing at night. It worked great! Until I ran out of aloe vera! :( you can sometimes find it fresh like that in international grocery stores for quite a good price - in the produce section.
Aloe Vera Juice is a miracle remedy for stomach ulcers.
I was diagnosed with multiple (3) peptic ulcers which were confirmed by biopsy not to be from H-pylori (they were actually from unripe tropical fruit I had eaten). When the prescribed medication didn't work and gave me side effects after one week I discontinued used and searched, painfully and desperately, for something to relieve the pain and help my stomach to heal. Milk and food neutralized immediately but then made it worse as it caused more stomach acid to be produced; water diluted but then irritated; juices irritated; anti-acid stuff worked instantly but for only a short time after which the pain got much worse. When a friend suggested Aloe Vera juice, I tried it and was pleased.
So for about 5 months I abstained from citrus and tomatoes (and tropical fruit) and kept an 8oz bottle of pure Aloe Vera juice with me, sipping anytime during day or night I had pain, whether with meals or without. Usually I only needed about 8oz-12oz per day and it tapered off as time went on and I had less pain.
At the end of 5 months, they scoped my stomach again and all the ulcers had healed completely. The doctor (a very competent gastroenterologist) was surprised it happened without any prescription medication.
I've since had another peptic ulcer due to use of aspirin and the aloe vera worked again. I consider aloe vera juice a miracle cure for stomach ulcers not caused by H. Pylori.
