Soothing and anti-itch effect of quercetin phytosome in human subjects: a single-blind study.

Background: We evaluated the ability of quercetin, a natural antioxidant formulated in a specific delivery system, to reduce skin inflammation induced by a variety of stimuli, including UV radiation, stimulation with a histamine solution, or contact with chemical irritants. In particular, we tested the soothing and anti-itch effect of Quercevita(®), 1% cream for external use, a formulation characterized by a phospholipids-based delivery system.

Patients And Methods: The study was a monocentric, single blind trial that enrolled a group of 30 healthy volunteers.
