Quercetin – The Allergy Sufferer's Friend?

Quercetin – an Important Flavonoid

Quercetin, a flavonoid belonging to the flavonol subgroup, is a natural yellow pigment found in many plants. It has been shown to have several significant health benefits. Studies suggest that quercetin can help with common colds, allergy symptoms, and even lung issues. Quercetin is found in fruits, berries, and vegetables.

Four Studies on Quercetin

Common colds affect millions of people each year, damaging the mucous membranes in the sinuses, which can lead to inflammation, cause sinus pain, and increase the risk of secondary viral infections.

One study shows that quercetin reduces inflammation caused by common cold viruses and actively prevents the viruses from replicating. The researchers concluded that "quercetin may be beneficial in the treatment of viral sinus infections, especially for patients with lung problems." [1]

Another study confirms that common cold viruses cause significant damage to the lining of the airways and that quercetin helps to stop this process. [2]

Yet another study highlights quercetin's ability to reduce allergic reactions and inflammatory processes in the airways, supporting earlier findings that quercetin helps stabilize mast cells involved in histamine production. [3]

An animal study indicates that quercetin may help improve lung function by preventing certain processes that destroy lung tissue. [4]

These studies suggest that quercetin could be a powerful natural substance for various respiratory issues and diseases. As mentioned, quercetin is found in fruits, berries, and vegetables. One study found that organically grown tomatoes contain 79% more quercetin than conventionally grown tomatoes. [5]
