Natural Antihistamines to Improve Allergy Symptoms

Some of you may know that the culprit behind all your allergy symptoms is histamine. When you are exposed to your allergens, they trigger your immune system to release histamine. Histamine is what causes the runny nose, the itchy eyes, and the sneezing. Most allergy medications are what we call antihistamines. They prevent your immune system from releasing histamine. But guess what? Many natural substances are also antihistamines, but without the sleepy side effects.

Natural Antihistamines


Flavonoids are compounds found in many plants. They are antioxidants and they also prevent the immune cells from releasing histamine. Quercetin is a type of flavonoids. Quercetin and other flavonoids are found in citrus fruits, apples, onions, parsley, sage, grapes, cherries, and dark berries. You may need several grams of quercetin to see quick improvements in your allergy symptoms.

Vitamin C

Vitamin C is another natural antihistamine. It works by breaking down histamine. Citrus fruits, peppers, melons, berries, tomatoes, dark leafy greens, cantaloupes, strawberries, and cabbage are all high in vitamin C. For acute allergies, you may need several grams a day. But be careful. Vitamin C can act as a laxative at high doses.


Nettles are one of my favorite herbs. They are high in minerals, flavonoids, and even vitamin C. Enjoy a cup of nettle tea to soothe your allergies. Infuse 1 cup of hot water with 1 TBSP of the dried leaves. Nettles do have a very herby flavor so add some mint to improve the taste.
