New research shows that it may be possible to alleviate symptoms of allergic asthma by using quercetin, a plant derivative found in fruits and vegetables.
In a recent study conducted at Comenius University, scientists found that quercetin could open up parts of the respiratory system that become narrow during asthma attacks.1
In some asthmatics, allergens such as pollen, dust, mold, and food can inflame and constrict the bronchial tubes and increase the sensitivity of these tubes to further inflammation and constriction. This reaction is known as allergic asthma.
According to the Asthma and Allergy Foundation of America, allergic asthma comprises fifty percent of asthma cases.2
Thanks to scientists at Comenius University, there may be a new way to help reduce that percentage. In their study, Acute Bronchodilator Effect of Quercetin in Experimental Allergic Asthma, they used three groups of male guinea pigs to determine if quercetin could alleviate the asthmatic reactions caused by allergens.
“This natural flavonol [quercetin] reduced allergic airway inflammation and hyperresponsiveness…,” the scientists said in their study.
MedicineNet.com says that the bronchial tubes, or airways, become inflamed during asthma attacks, narrowing and reducing the flow of air.3 The site also notes that during asthma attacks, the bronchial tubes undergo a bronchospasm, a muscular constriction of the airways.
Asthmatics are prone to more bronchospasms due to airway sensitivity — a condition that is part of bronchial hyperresponsiveness.
So, if quercetin can reduce inflammation and hyperresponsiveness, then asthmatics have an opportunity to get relief from their symptoms.
