Quercetin

Quercetin is a powerful antioxidant that helps fight free radicals that damage cell membranes and cause cell death. A clinical study at the University of California showed the positive effects of quercetin on prostate and kidney health. Quercetin exhibits an allergic reaction, causes swelling of the nasal mucosa and detects a headache. It is used for seasonal clothing for flowering, dust and for various allergic reactions to environmental irritants.
