A recent study found that a celery seed compound had potent bacteriacidal activity against H. Pylori. H. Pylori is a bacteria which is responsible for a large number of gastric (stomach) ulcers. In this study, the seeds were alcohol extracts, so if you just eat celery seeds it may or may not work, but a tincture of celery will kill H.pylori, but alcohol increases the production of stomach acid which can worsen an ulcer. Steve Gomberg, a former world class chef that is currently a nutritionist at ECCM said that you can cook the celery seeds in a wine reduction which will help extract the compound and burn off the alcohol (brilliant!). Steve will be uploading an ulcer killing recipe to our website in the patient section (requires login).
