Consider the Alternatives
Finally, consider the following complementary therapies, courtesy of Walter Crinnion, ND, director of Healing Naturally, a naturopathic medical practice in Kirkland, WA.
Quercetin A nutrient found in onions and other foods, quercetin appears to inhibit allergic reactions. Take a 600-mg capsule (far more than you could ever get from eating onions) two or three times a day.
Stinging Nettle (Urtica dioica) Get a standardized, freeze-dried extract of this herbal antihistamine, and take three capsules three times a day. Or take 1 teaspoon of 1:5 tincture three times a day. Choose products made from the whole plant; avoid products made from the root. Start taking nettle before allergy season begins, and continue taking it daily through the season or whenever your particular allergy surfaces.
