The Seasonal Allergy Sufferer and the Potential of Quercetin

Are you one of the approximately forty percent of people with allergies or seasonal allergies? Do Claritin and Flonase work for you somewhat or not at all? I don’t know about you, but every spring, I get blasted with seasonal allergies. Symptoms range from coughing, watery eyes, runny nose, and sneezing to migraine headaches. I occasionally use over-the-counter allergy medications with varying degrees of success.

Fortunately, I have found another tool in my seasonal allergy fight: quercetin.

Quercetin is a naturally occurring flavonol, or flavonoid, the yellowish antioxidant pigment found in skins of onions, berries, apples, berries, tomatoes, and buckwheat tea. It is a potent mast cell stabilizer (mast cells are what produce histamine, the molecule released in response to cells coming into contact with allergens, which is what makes you sneeze and look like a 2-year-old with snot coming out of your nose).

By stabilizing mast cells, quercetin inhibits the release of histamine and other inflammatory mediators. Studies indicate that it works better than Cromolyn, an old asthma medication with some nasty side effects. The good news about quercetin is it is very well-tolerated. 

Because of similar inflammatory pathways that affect asthmatics and patients with urticaria (hives) eczema, quercetin can also have potential benefits for that patient population.

Also, consider reducing histamine-rich foods if you have any of the above ailments. Recent studies on patients with urticaria showed that eliminating tuna, mackerel, pork, chicken, and spinach and fermented foods such as cabbage, yogurt, cheese, wine, and beer for four weeks had significant clinical improvements in urticaria severity and plasma histamine levels. Here’s to less mucus, itching, coughing, and sneezing everywhere!
