Spices and herbal remedies have been used since ancient times to treat a variety of disorders. It has been experimentally demonstrated that spices, herbs, and their extracts possess antimicrobial, anti-inflammatory, antirheumatic, lipid-lowering, hepatoprotective, nephroprotective, antimutagenic and anticancer activities, besides their gastroprotective and anti-ulcer activities. Despite a number of reports on the toxicity of herbs and spices, they are generally accepted as safer alternatives to conventional therapy against gastric ulcers. To this end, it is also believed, that excessive consumption of spices may favor the pathogenesis of gastric and duodenal ulcer and some studies have substantiated this common perception. Based on various in vivo experiments and clinical studies, on the effects of spices and herbs on gastric ulcers, it has indeed been shown that certain spices do possess remarkable anti-ulcer properties mediated by antisecretory, cytoprotective, antioxidant, and anti-Helicobacter pylori effects and mechanisms regulated by nitric oxide, prostaglandins, non-protein sulfhydryl molecules and epidermal growth factor expression. Accordingly, their consumption may attenuate and help prevent peptic ulcer disease. In the present review, the beneficial effects of spices and herbal nutritive components on the gastric mucosa are discussed against the paradigm of their deleterious potential.

Helicobacter pylori infection has been significantly linked to Peptic Ulcer Disease and Gastric Cancer.Metabolomic fingerprinting may offer a principal way of early diagnosis and to understand the molecular mechanism of H.pylori-induced pathogenicity.The rationale of the study is to explore the underlying distinct metabolic mechanisms of H.pylori-induced PUD and to identify potential biomarkers for disease diagnosis and associated risks using Gas chromatography/mass spectrometry.GC/MS-based analytical method was used to compare metabolic profiles of healthy controls(N=20)and peptic ulcer patients(N=45).Acquired metabolomic data were analyzed by constructing a diagnostic model using principal component analysis and a non-parametric two-tailed paired Wilcoxon analysis to identify disease-specific metabolic biomarkers.A total of 75 low-molecular-weight endogenous metabolites were detected during comparative metabolomic analysis of PUD vs.healthy gut tissues,among which 16 metabolites are being proposed to be diagnostic markers of Human PUD.Perturbations related to amino acids,carbohydrates,fatty acids,organic acids,and sterol metabolism were significantly revealed during this differential metabolomic profiling.Results convincingly suggest that metabolic profiles can contribute immensely in early diagnosis of the disease and understanding molecular mechanisms of disease progression for predicting novel drug targets for prophylactic and anaphylactic measures.
