"Quercetin has anti-inflammatory and anti-allergic effects. These activities are caused by the strong antioxidant action of quercetin. It will help to combat free radicals molecules, which can damage cells.

 

The anti-inflammatory action of quercetin is caused by the inhibition of enzymes, such as lipoxygenase, and the inhibition of inflammatory mediators. Quercetin also inhibits the release of histamine, which causes congestion, by basophils and mast cells."

About Quercetin

 

Quercetin is the most abundant of the flavonoids. Quercetin belongs to the flavonoids family and consist of 3 rings and 5 hydroxyl groups. Querctin is also a building block for other flavonoids. Quercetin occurs in food as a aglycone (attached to a sugar molecule). Only a small percentage of the ingested quercetin will get absorbed in the blood.

Sophorae Japonica

Quercetin 99% can be found as an ingredient in skin care formulations intended for acne treatments, antioxidant formulas, and in UV protection skin care recipes. It also has properties that make it useful in scar cream products.
