Quercetin is a plant pigment (Flavonoid) found naturally in a number of foods including apples, onions, teas, berries, and red wine.
Quercetin acts as an antioxidant, neutralising free radicals which are the chemical by-products that harm cell membranes and damage DNA.
Quercetin also possesses antihistamine and anti-inflammatory properties. Research suggests that quercetin could be an effective antihistamine because it restricts histamine from being released from cells.
Quercetin may help with the following conditions:
- Allergies
- Cardiovascular disease
- Inflammation
- Colds
These anti-allergy properties indicate that quercetin could help to treat bronchitis and asthma.
Quercetin may also improve blood vessel cell health and blood flow through arteries in people with heart disease.
