Every year it seems that seasonal allergies (especially cedar, right now) get worse in people. Some try to blame the trees while others seem to think they're 'just the way it is.' I've never actually had cedar allergies (coincidence that I eat primarily organic and local foods?) so I can't speak from experience, but I've also heard many people tell me their cures.
While not a complete cure, many people say that a daily regimen of local honey significantly reduces the severity of their allergies. The theory is that ingesting the pollen (assimilated into honey by bees) helps your body recognize it as food and not a foreign protein so you don't react as such. Now, there's something very important to this remedy - pollen count. Some tests have been run on all local honeys and Round Rock Honey has by far the most diverse pollen profile and the most local pollens of any of the honeys. One tablespoon a day of this yummy goodness and in a couple of weeks you may notice pollen allergies subsiding.
I hear stories of acupuncture being effective for some and not for others (maybe depends on the practitioner?), but one treatment that has worked for everyone who has tried it is The Love Cleanse. A guided cleanse by Kim Love, she helps you identify underlying food allergies (which are present in 90% of seasonal allergy sufferers) and balances your body chemistry to better handle all environmental toxins. Her program works.
I do not believe allergies are simply a way of life in Texas. They're a symptom of an underlying issue in the body. Until you find and treat the issue, nasal sprays and pills for the symptoms are just an expensive way to put off dealing with it. And just in case you're getting confused - I'm not a doctor and this is not medical advice. Just my opinion, that's all.
