Besides lifestyle change, nasal flushing and immunotherapy, there are some natural plants or plant extracts that work well to treat or prevent allergy symptoms.

Quercetin

Quercetin is a natural compound derived from plant. It is a natural antioxidant that can be found in citrus fruits, onions, apples, parsley, tea, tomatoes, broccoli, lettuce and wine.

Quercetin supplements can prevent allergy attacks. It is best to start using it six weeks before allergy season.

Allergy Fighting Foods

Foods rich in omega-3 fatty acids help alleviate allergy symptoms. Omega-3s can be found in cold-water fish, walnuts, flaxseed oil, grass-fed meat and eggs.

Also, add spices such as horseradish, chili peppers or hot mustard to your food. They act as natural decongestants.

Stinging Nettle

Stinging nettle (see image) acts like many of the drugs sold to treat allergies. But it has the advantage of not causing the side effects like dry mouth and drowsiness.

You can make your own tinctures or teas with stinging nettle. Or you can use stinging nettle extract capsules.

Butterbur

Butterbur is another plant used to treat allergies. It is as effective as the drug cetirizine,  the active ingredient in Zyrtec. However, butterbur doesn’t cause drowsiness.
