The syndrome of the functional not ulcer dyspepsia (FNUD) can be met independently as well as in association with a number of widespread diseases of the digestive system. Main reasons for its emergence are the violations of the motor function of the stomach and duodenum, and also a hypersensibility of stomach wall receptors to stretching. Abundance of complaints, linked to stomach pathology, is very high and occurs in industrialized countries at 30-40% rate of the population, and a half of all cases are the share of non ulcer dyspepsia.
Clinical trials of domestic herbal syrup “Limonidin” on a syndrome of FNUD are conducted on the basis of scientific and clinical diagnostic center of SRICID on 30 patients (63.3% of which are women), middle age of 41.55±11.82. Patients were included in a research only from their informed consent. Observation was conducted for 21 days. At all patients included in a research the endoscopic study of proximal departments of digestive tract and ultrasound examination of abdominal organs was conducted. In the presence of organic pathology patients were excluded from a research. From the results of the experiment it might be concluded that the studied herbal medicine possesses along with antiinflammatory and antiseptic properties spasmolytic influence on a smooth emasculation of a stomach. Physiological activity of syrup might be defined by presence of epigallocatechin-3,3,5,7,3',4',6'-hexahydroxyflavan, (-)-epigallocatechin-(4β→8)-2R, 3R(-)-epigallocatechin-3, (-)-epigallocatechin-(4β→8)-3,5,7,3',4',6'-hexahydroxyflavan, myricetin and a number of its glycosides.
