Allergy
Allergic rhinitis is an allergic reaction to airborne particles that primarily affects the nose and eyes. There are two types of allergic rhinitis: seasonal allergic rhinitis (hay fever) and perennial allergic rhinitis, which occurs year-round.

Allergens (substances that cause allergic reactions) responsible for allergic rhinitis usually enter the body by inhalation. Hay fever is caused by outdoor allergens, and perennial allergic rhinitis by indoor allergens. Symptoms of allergic rhinitis resemble a cold, except that they occur only at particular times: during certain seasons or weather patterns (hay fever), and around certain animals or small household pests (perennial allergic rhinitis). Millions of people are affected by allergic rhinitis. Many people who have allergic rhinitis also have asthma.

Vitamin A and vitamin C support the immune system; vitamin C, the main antioxidant in the cells of the respiratory passages, may also have anti-inflammatory and antihistamine effects. The B vitamin pantothenic acid may reduce nasal congestion. You may want to take these three nutrients during allergy season, even if you opt for traditional drugs for specific symptom relief.

And, for severe cases of hay fever, ephedra (ma huang) may be useful because it opens the respiratory passages. You can use ephedra with quercetin and nettle, but not with prescription or over-the-counter antihistamines or decongestants. Ephedra may cause insomnia. It should not be used by people with heart disease, hypertension, or diabetes.
