AbstractOur field surveys on the traditional medicine in Turkey revealed that several plants are used for the treatment of ulcers; Cedrus libani, Centaurea solstitialis ssp. solstitialis, Cistus laurifolius, Hypericum scabrum, Plantago major, Sambucus ebulus and Spartium junceum. Various extracts prepared from these plants were tested by using a water immersion‐stress ulcer model in rats to confirm the claimed activities. Pharmacological experiments clearly demonstrated that the aqueous extracts of all the plants given orally showed significant antiulcerogenic activity.
