In vivo tests of natural therapy, Tibetan yogurt or fresh broccoli, for Helicobacter pylori infection.
Plants and probiotics have a long history in the treatment of gastrointestinal ailments. Our aim was to evaluate the effectiveness of Tibetan yogurt and fresh broccoli tips in Helicobacter pylori- (H. pylori) infected volunteers, using the urea breath test (UBT) to assess the effect on H. pylori. Clinical trials consisted of ingestion of approximately 135 g of fresh, finely minced juvenile broccoli tips (var. Emperor) in commercial plain yogurt t.i.d, for ten servings (3.3 days) or ingestion of freshly made Tibetan yogurt whey (120 ml) given twice a day for 3.5 days. Urea breath testing was done before and after the natural therapies. Five volunteers received broccoli tips and seven received Tibetan yogurt. No trend for a beneficial effect was seen; the UBT results (delta over baseline) before and after yogurt (35.5+/-12.8 vs. 40.7+/-12.2) (p=0.76) or broccoli (15.8 vs. 19.4) (p=1.0) were unchanged. Antimicrobial end products derived from Tibetan yogurt or broccoli tips have little or no anti-H. pylori effect in vivo. It appears that the gastric mucosal microenvironment apparently shielded H. pylori. In vitro studies suggesting anti-H. pylori activity of compounds should be considered as hypotheses to be tested.
