Hay fever can be caused by trees, grasses, molds, weeds and even disintegrated insects' bodies, among other offenders. But the greatest sinner is the ragweed. In only 5 hours one ragweed plant can produce 8 billion pollen grains that can be air borne over a distance of 75 miles. And it takes only a little of the pollen to trigger an attack in a sensitive person, Dr. Fears reveals. Of the four species of ragweed, three grow knee high, but the fourth — giant ragweed — reaches head high. For some unknown reason, the giant ragweed’s scientific name, is Ambrosia triflda Ambrosia, of course, means "pleasing to'taste or smell." Any have fever, sufferer would violently disagree with the botanist who pinned this label on it. It may seem strange, but the ragweed pollination season begins earlier in.4he north than in the soud^ Ihn parts of Canada' ragged' starts pollinating in the latter part of July, whereas in Southern Texas it begins about the middle of September. This is because pollination occurs as the amount of sunlight becomes less. Thus the farther south the plants are, the later their pollination starts. Why some /of us become allergic to tre$ pollen, others to ragweed, peanuts, molds or insects remains a mystery. But it is known that the allergic tendency is -
