Quercetin is a flavonoid, a type of plant pigment found in various fruits, vegetables, and grains. It is known for its antioxidant and anti-inflammatory properties. While it is primarily recognized as a dietary supplement, it is naturally present in many foods, including apples, berries, onions, grapes, citrus fruits, and leafy green vegetables..

Quercetin has been studied for its potential benefits in managing respiratory problems, particularly in relation to allergies, asthma, and viral infections. Here are some key points about its effects on respiratory health:

Quercetin has been found to possess anti-inflammatory properties, which can help reduce airway inflammation associated with respiratory conditions such as asthma. It may inhibit the release of inflammatory mediators, such as histamine, leukotrienes, and prostaglandins.

Quercetin acts as an antioxidant, which means it helps neutralize harmful free radicals in the body. This antioxidant activity may contribute to the protection of lung tissues from oxidative stress, potentially benefiting respiratory health.

Quercetin has been studied for its potential to alleviate allergic reactions. It may help stabilize mast cells, which are involved in the release of histamine and other compounds during an allergic response. By modulating these cells, quercetin might help reduce allergy symptoms like runny nose, sneezing, and itching..

Some studies have explored the potential of quercetin in the management of viral respiratory infections. It has been suggested that quercetin may interfere with the replication of certain viruses, including the influenza virus.
