Hello, and welcome to the forum!
I'm no expert at all and don't have real experience with ulcers, but I know that doctors are quick to prescribe pills like Prilosec that have very bad side effects when taken on a daily basis. So you're right to be concerned.
I've only had experience with general heart burn, occasional acid reflux, etc. I've found that eating a small apple every evening a couple of hours before bedtime has almost eliminate my heartburn during the night, which was a big problem for me.
Also, if there's no health issues for him with salt, a half teaspoon of baking soda in a small amount of water usually eliminates any symptoms of heartburn, and better than the pills.
In the morning I take 2 tablespoons full of organic lemon juice mixed with 1/3 teaspoon of baking soda just to make my system more alkaline as opposed to acidic. Good side effect of this practice is cancer thrives in acid environments, so alkaline is good.
Here's an old article that has some good general info, including recommendations on h Pylori. Keep in mind when using a honey, it should be raw and unfiltered, Manuka is expensive but it has a lot of health benefits. Good he's using aloe, my brand is Lily of the Desert aloe juice, inner fillet. For coconut oil I use Nature's Way. http://www.naturalnews.com/028644_st..._remedies.html
One of the very best home remedies for ulcers is eating raw cabbage. Juicing the raw cabbage will make it easier to take and mixing it with carrots in the juicer will make it better tasting. Drink half a cup before each meal and at bed time and make sure that it is fresh. Your ulcer may be gone in only a few weeks.
* Eat at least three bananas a day. These fruits contain an antibacterial substance that inhibits the growth of ulcer-causing H. pylori. Studies show that animals fed bananas have a thicker stomach wall and greater mucus production in the stomach, which helps build a barrier between digestive acids and the lining of the stomach. Eating plantains is also helpful.
* Cayenne pepper is wonderful for healing ulcers as well as dulling the pain. It is a bit strong and may take some getting used to at the outset. Start with one-eighth teaspoon of cayenne pepper in a glass of water twice a day and work up to a quarter-teaspoon. You can also take cayenne capsules that you can get at the health food store. Take three a day immediately after meals.
* The bark of slippery elm soothes the mucous membranes that line the stomach and duodenum. It is often taken in powdered form. Some herbalists recommend taking a teaspoon of powdered slippery elm bark added to one cup of warm water three times a day.
* Colloidal silver helps kill the H. pylori bacteria and helps heal injured stomach tissues.
* Raw honey soothes and reduces inflammation of the lining of the stomach and is good for healing as well.
* Garlic's antibacterial properties include fighting H. pylori. Take two small crushed cloves a day.
* Plums and other red and purple colored foods such as berries inhibit the growth of H. pylori.
* Coconut oil kills the bacteria that cause ulcers and gas, but it's mostly a long-term remedy.
A few other good ulcer remedies are: raw goats' milk, barley water, aloe juice, propolis capsules, licorice root or marshmallow root.
