Quercetin Uses and Benefits
1. Prevent allergy symptoms
Quercetin inhibits the release of histamine from mast cells during allergic attacks. This type of histamine is one of the culprits of allergy symptoms such as sneezing, runny nose, and itchy skin.
2. Antioxidant
It reduces inflammation by scavenging free radicals. In fact, quercetin aglycone and its conjugate metabolites protect cells from damage caused.
3. Anti-inflammatory
Quercetin inhibits enzymes in the body. It is usually caused by inflammation (ie cyclooxygenase [COX] and lipoxygenase [LOX]) also tested in vivo, which proved to be anti-inflammatory. Quercetin inhibits pro-inflammatory cytokines for potential use as a therapeutic anti-inflammatory drug.
4. Prevent Cancer
It has antioxidant properties. It also induces apoptosis by inducing kinase and inhibiting cell cycle inhibition. In addition, quercetin can play an anticancer effect.
5. Prevent cardiovascular disease
It has been found in some human and animal studies to improve endothelial cell function in blood vessels. It relaxes the aorta and improves blood flow by stimulating nitric oxide production. It can prevent cardiovascular disease, reduce cardiovascular disease and reduce the incidence of stroke.
6. Protect the stomach
Quercetin Powder is protective against ethanol-induced gastric ulcers. It inhibits the growth of Helicobacter pylori.
