1plant extract informations

   Description of plant extract myricetin:

(1) Myricetin is a naturally occurring flavonol, a flavonoid found in many grapes, berries, fruits, vegetables, herbs, as well as other plants. Walnuts are a rich dietary source. Trace amounts can be found as glycosides.It is one of the phenolic compounds present in red wine.

(2) Myricetin has antioxidant properties. In vitro research suggests that myricetin in high concentrations can modify LDL cholesterol such that uptake by white blood cells is increased. A Finnish study correlated high myricetin consumption with lowered rates of prostate cancer.

(3) Another 8-year study found that three flavonols (kaempferol, quercetin, and myricetin) reduced the risk of pancreatic cancer by 23 percent.
