Several ethnomedicinal plant remedies used in Pinarbasi, Kayseri, in particular those which are used for the treatment of several peptic ulcer symptoms such as stomach ache, heartburn, etc. were selected for evaluation of their anti-ulcerogenic potential. In order to confirm the claimed activities, decoctions were prepared from aerial parts of Malva neglecta Wallr. (Malvaceae), leaves of Potentilla reptans L. (Rosaceae), fruits of Rumex patientia L. (Polygonaceae), aerial parts of Sanguisorba minor Scop. ssp. muricata (Spach) Briq. (Rosaceae), aerial parts of Sideritis caesarea Duman, Aytac&Baser (Lamiaceae), and flowers of Verbascum cheiranthifolium Boiss var. cheiranthifolium (Scrophulariaceae) according to their described folkloric applications. Pharmacological experiments clearly demonstrated that the extracts of all plants given orally showed significant gastric protection against the ethanol-induced gastric ulcer model in rats. Furthermore, healing effects were also confirmed through histopathological examination.

Rumex acetosa is a perennial herb that is widely distributed across eastern Asia. Although the hot water extract of R. acetosa has been used to treat gastritis or gastric ulcers as a folk medicine, no scientific report exists for the use of this plant to treat gastric ulcers. Hence, the present study was undertaken to assess the anti-ulcer activity of water and 70% ethanol extracts obtained from R. acetosa, using an HCl/ethanol-induced gastric ulcer model in mice. Anti-inflammatory and free radical-scavenging activities of these two extracts were also evaluated and compared. As a result, the administration of R. acetosa extracts significantly reduced the occurrence of gastric ulcers. However, significant differences in protective activity against gastric ulcers were observed between the two samples. In the case of the group pretreated with an ethanol extract dosage of 100 mg/kg, the protective effect (90.9%) was higher than that of water extract (41.2%). Under histological evaluation, pretreatment with R. acetosa extracts reversed negative effects, such as inflammation, edema, moderate hemorrhaging and loss of epithelial cells, presented by HCl/ ethanol-treated stomachs. Meanwhile, R. acetosa extracts showed potent DPPH radical-scavenging activity and decreased NO production in a murine macrophage cell line, RAW 264.7, in a dose-dependent manner without affecting cellular viability. The greater anti-ulcer and NO production inhibitory activities exhibited by ethanol extracts compared to water extracts could be ascribed to the higher emodin levels, a major anthraquinone component of this plant.
