Try licorice root (not the candy, the herbal root), for that ulcer.
Here's just one link about it, there are other sites that talk about it too. if you scroll way down on the page of the following link, you'll see: "In one study, licorice root fluid extract was used to treat 100 patients with stomach ulcers for 6 weeks. Ninety percent of the patients improved, with ulcers completely disappearing in 22 of the patients."
