Background: Che day is a commonly used traditional medicine among the mountainous ethnic people to treat gastro-duodenal ulcer. Its scientific name is Ampelopsis Cantoniensis Planch (Vitaceae). It is known that chemical components of che day includes flavonoid, tanin and uronic compound, which is able to relieve pain completely. Objectives: Evaluation of analgesic, cicatrisation, anti-inflammation and Helicobacter Pylori (HP) eradicating effects of che day in the treatment of gastro-duodenal ulcer and also investigate the side effects of che day. Subject and methods: 80 patients with gastro-duodenal ulcers were seen with endoscopy, suffering from epigastric pain. The study was carried out in the way of a double - blind method, comparing the results between the group che day and the Alusi cotrolled group. Results: On average, the time when the pain receded is 8.9 days in the che day group, faster than the Alusi controlled group (17.35 days, p < 0.01). The rate of the cicatrisation by che day is 79.55%, higher than the Alusi (47.22%; p < 0.001). In pathological anatomy, the rate of HP eradicating of che day is 42.5%, higher than the Alusi (19.35%, p < 0.01); the rate of recovery from gastritis of che day is 23.25%, higher than the Alusi (9.09%, p < 0.01) and the rate of total recovery of che day is 44.19%, higher than the Alusi; (27.27%, p < 0.01), Conclusions: The che day is effective in relieving gastro-duodenal ulcer \u2013 induced pain for the average of 9 days. In endoscopy, the rate of cicatrisation of che day is 79.55%, in which, good cicatrisation is 54.28%. In pathological anatomy, the che day is effective in eridicating HP with the rate of 42.5 %; The rate of recovery is 23.25% and che day has no side effects.
