The flowers and flower buds of Cistus laurifolius L. are used for the treatment of peptic ulcers. Through the bioassay-guided fractionation of the material, using water immersion and immobilisation-induced stress ulcer model, the EtOH-precipitated part from the aqueous extract (E-H2O decreases) was
The antiulcer activity of a short-boiled aqueous extract from aerial parts of Cistus incanus was studied in rats against gastric lesions induced by necrotizing agents (1N HCl and absolute ethanol), indomethacin, serotonin and reserpine. The extract, containing bioflavonoids, was orally administered
