Evidence supporting the use of: Quercetin
For the health condition: Gastritis
Synopsis
Source of validity: Scientific
Rating (out of 5): 2
Quercetin is a flavonoid found in many fruits and vegetables, and its use for gastritis is primarily supported by preclinical scientific studies rather than traditional medicine or robust clinical trials. Several laboratory and animal studies suggest quercetin has anti-inflammatory, antioxidant, and gastroprotective properties. For example, research has demonstrated that quercetin can reduce gastric mucosal damage in animal models of gastritis by scavenging free radicals, inhibiting inflammatory cytokine production, and reducing oxidative stress. In some rodent studies, quercetin supplementation was shown to decrease ulcer formation and improve markers of gastric healing. The proposed mechanisms include inhibition of gastric acid secretion, stabilization of mast cells, and modulation of signaling pathways involved in inflammation and oxidative injury.
However, it should be noted that there is a lack of well-controlled, large-scale human clinical trials specifically investigating quercetin for the treatment or prevention of gastritis. Most evidence remains at the experimental or preclinical level, and more research in human populations is needed to establish efficacy and safety. Therefore, while there is some scientific rationale for the use of quercetin in gastritis based on laboratory studies, its routine use for this purpose is not yet strongly supported by clinical data. Clinicians and patients should exercise caution and consult healthcare professionals before considering quercetin supplementation as a treatment for gastritis.
