When my allergies act up I use QBC, Quercitin Bromelain Complex, by Douglas labs. Quercitin is a natural antihistamine, bromelain is a natural anti inflammatory, and of course C is viamin C, known as a natural decongestant. The vitamin C, in this product is buffered, unlike the other C's, that are too acidic to take long term. This particular product also contains magnesium for added benefit, and a co factor for the other active ingrediants to work effectively. As well as a sinus spray, containing olive leaf, a natural antibiotic, as well as grapefruit seed extract, 2 puffs each nostril 3 times a day. Very effective. A sinus cleanse may also help. http://hubpages.com/health/Is-it-a-cold-or-allergy... I give the recipe in my article. By removing the allergen, you lessen the response.. It is advisable to start your regimen 30 days before hay fever season starts. Do not take any drug, over the counter, or prescription, with grape fruit seed.
Other advice, if it is true hayfever, it is the pollen from ragweed. Golden rod blooms at the same time as ragweed, when you see those yellow blooms, you know that ragweed is also present. Keep the windows on your car, and in your home closed. You carry the pollen with you, on your clothes and in your hair, take a shower after being outside. Do not use chamomile tea, capsules, or other wise, it contains the same proteins as ragweed, as well as melons, cantaloupe, water melon, and many others, by avoiding these proteins, you lesson the response.
