The relationship between quercetin and lung health

Welcome to our brand official website. Here, we are committed to providing you with the highest quality products and services. Today, we will introduce you to a natural antioxidant called quercetin and its close relationship with lung health.

Quercetin is a flavonoid compound widely present in plants, such as apples, onions, red wine, etc. It has various biological activities, including antioxidant, anti-inflammatory, and anti allergic properties. In recent years, an increasing number of studies have shown that quercetin has a positive promoting effect on lung health.
Antioxidant effect

The lungs are one of the most vulnerable organs in the human body to oxidative stress damage. Long term smoking, air pollution, ultraviolet radiation and other factors can lead to the production of a large amount of free radicals in lung cells, which in turn can trigger oxidative stress reactions. Oxidative stress can lead to damage to lung cell membranes, enzyme inactivation, DNA damage, etc., thereby increasing the risk of lung disease.

Quercetin has strong antioxidant capacity and can eliminate free radicals in the body, reducing the damage of oxidative stress to lung cells. Research has found that quercetin can reduce the production of inflammatory factors in the lungs, alleviate inflammation, and protect the lungs from oxidative stress.

Anti-inflammatory effect
Chronic bronchitis, asthma and other lung diseases are often accompanied by inflammatory reactions. Inflammatory reactions can lead to symptoms such as lung tissue damage, increased mucus secretion, and airway contraction, seriously affecting the quality of life of patients.

Quercetin has a good anti-inflammatory effect, which can inhibit the production of inflammatory factors and alleviate inflammatory reactions. Research has found that quercetin can reduce the levels of inflammatory factors such as interleukin-6 (IL-6) and interleukin-8 (IL-8) in the serum of asthma patients, thereby improving asthma symptoms. In addition, quercetin can also inhibit the occurrence of pulmonary fibrosis and delay the decline of lung function.

Anti allergic effect
The incidence of allergic diseases such as allergic asthma and allergic rhinitis is increasing year by year worldwide. Quercetin has anti allergic effects and can alleviate allergic reactions. Research has found that quercetin can inhibit the release of histamine and other allergic mediators by mast cells, thereby alleviating allergic symptoms.”
