Preventing the common cold can be a dicey experiment from year to year. It always seems that illness hits at the worst times: when we are busy, stressed, traveling, preparing for a big event or presentation. I believe that illness is the result of these things and not just a unfortunate coincidence. Live in balance and you’ll notice that your health improves with it. Balance means eating well, exercising, drinking fluids, getting sufficient rest and maintaining a positive attitude. On the other hand, you can help boost your immune system by taking some herbal supplements. Try these: andrographis paniulata, panax quinquefolium, sacharomyces cervisiae, yeast beta-glucan, zinc, vitamin C, vitamin B and Echinacea.
