What are Allergies?
An allergy is an overreaction of the immune system to a normally innocuous substance that enters the body. Sneezing, a runny nose, and itchy eyes are symptoms characteristic of allergic rhinitis, the medical name for a common allergic reaction to a variety of airborne particles. The specific irritants, or allergens, that trigger rhinitis vary from person to person. Seasonal allergies (commonly called hay fever) are generally caused by airborne pollens and outdoor mold spores that proliferate in warm weather, from spring to fall. Perennial allergies, triggered by such allergens as dust, animal dander, or mold spores, can flare up at any time of the year. Although the symptoms of both types of allergies are the same, those who suffer from allergic rhinitis may be less resistant to sinus infections, colds, flu, or other respiratory illnesses.
Allergic rhinitis may develop anytime after birth, but usually peaks in the pre-teen or teen years and tends to diminish later in life. It affects as much as a quarter of the young adult population. Whether seasonal or perennial, allergies are not a serious health problem, but they can make life miserable during an attack. Fortunately, symptoms can be controlled with herbs and nutritional supplements as well as over-the-counter or prescription medications.
Key Symptoms
What Causes Allergies?
Allergic rhinitis originates in the inability of the body's immune system to distinguish between disease-causing bacteria or viruses and harmless particles, such as pollen or dust. When an allergen enters the nose, throat, or eyes of someone who is susceptible to it, the body responds first by developing a sensitivity, then, upon further exposures, by releasing illness-fighting histamines and other inflammatory compounds (designed to fight off this foreign "invader") into the affected areas. The resulting inflammation of the mucous membranes produces the symptoms of hay fever.
Allergic reactions can be triggered by many different allergens. Seasonal allergies are most often caused by pollen--from trees and grasses in the spring, from ragweed and other weed pollens in late summer and early fall, and from outdoor mold spores during spring and fall. Mold spores, animal dander, tiny mites in household dust, cigarette smoke, certain cosmetics, and feathers can produce allergy attacks throughout the year.
What causes the immune system to overreact to certain allergens is not known. Genetics may play a role, since allergic rhinitis seems to run in families. Other factors that may predispose a person to allergies include poor nutrition, exposure to environmental pollutants, overuse of decongestant nasal sprays, hormonal disturbances related to pregnancy, the use of oral contraceptives, and thyroid problems.
Treatment and Prevention
The primary way to treat allergic rhinitis is with antihistamines--substances that can control allergy symptoms by blocking the histamines that cause them. Antihistamines are available in over-the-counter and prescription medications, but these drugs can have various side effects, including drowsiness and dry mouth. Certain supplements, on the other hand, can also act as antihistamines, helping to control allergy symptoms without producing annoying side effects.
Except for the herb ephedra, which should not be taken with certain conventional drugs, such as medicines for high blood pressure or other decongestants, all the supplements recommended by Nutricraze for allergy relief can be taken together, preferably for the duration of the allergy season. The supplements alone may be sufficient to bring relief. If not, they can also be taken in combination with any prescription or over-the-counter medications your doctor recommends.
Prevention is also important. If at all possible, try to eliminate or avoid exposure to known allergens. Your doctor or an allergy specialist can help you identify the cause of your allergies. And if it's not possible to totally avoid an allergen, you can at least try to limit your exposure to it--for example, stay indoors when the pollen count is high and use an air conditioner.
Just a reminder: If you have a medical condition, always check with your doctor before beginning a supplement program.
How Supplements Can Help
Unlike conventional antihistamines, which try to counter the effects of histamines after they've already been released, the flavonoid supplement quercetin actually helps prevent the body's release of histamines in the first place, and quercetin doesn't have side effects. It's particularly effective when combined with the anti-inflammatory enzyme bromelain, derived from the pineapple plant, which help soothe irritated mucous membranes.
Quercetin also works well with the herb nettle, also called stinging nettle, which helps stop the sneezing and itching that often accompanies an allergy attack. Nettle also helps reduce the swelling of nasal passages.
Take vitamin C and the B vitamin pantothenic acid throughout the allergy season, with either quercetin or conventional antihistamines. Vitamin C boosts the immune system and is also thought to have anti-inflammatory and antihistamine properties. Pantothenic acid may help relieve nasal congestion.
Anise, ginger, and peppermint are natural herbal antihistamines. Ginger and peppermint are also natural decongestants. Sipping teas made from these herbs, singly or in combination, can help relieve allergy symptoms. Parsley, for instance, inhibits the secretion of histamine, and ginkgo biloba contains several chemicals that interfere with platelet activating factor (PAF), which plays a key role in triggering allergies. In Chinese medicine, ginkgo has a long use for asthma and bronchitis.

Self-Care Remedies
Be aware of daily pollen counts, and try to stay indoors with the windows closed when pollen counts are high. Use an air-conditioner at home and in the car, and clean the filters regularly.
If your allergies are triggered by dust and dander, get rid of carpets and put your cat up for adoption and use only washable furniture slipcovers and allergy-proof pillow covers and mattress. Replace feather pillows with synthetic ones. To eliminate the dust mites that collect in bedding and slipcovers, and wash the fabrics in very hot water once a week.
Eliminate damp areas in the home that can foster the growth of mold.
