Quercetin
Quercetin is a kind of flavonoid. Even though there still is not enough research to say that quercetin can be an effective remedy to allergies, this substance can keep histamine from being released. As a result, it will alleviate some allergy sings involved in this inflammatory chemical, such as itching and sneezing. You can take in quercetin naturally in some foods and drinks like black tea, capers, red onions, red grapes, berries, and apples, especially the skin. Also, there are quercetin supplements which are available in many stores. Ideally, you should take around 200 to 400 mg per day for hay fever or allergies. [4]
