I thought it would be a good time to mention one of my favorite herbs, astragalus root. With all the talk about colds and the flu, it's helpful to know of an herb that enhances your immune system without any side effects and is a relatively inexpensive herb as well. I first read about astragalus in Dr. Andrew Weil's book, "Natural Health, Natural Medicine". It's great for use when you think you may be catching something, but since it's non-toxic, you can just use it regularly to keep your immune system strong. We use the powdered herb in capsule form and follow the directions on the bottle, but tincture or tablets are fine. If we think we're getting a cold or something, we increase the dosage temporarily to give ourselves an extra boost. You can also find astragalus root in Chinese grocery stores and some health food stores as dried, sliced root that you can simmer as tea or in soup.
Still, of course, the best thing to help you prevent getting sick is hand-washing and avoiding touching your face (especially eyes and nose). Don't you think that shaking hands should be put on temporary hold until after flu season? We can just show our palms to each other to say that we're not carrying any weapons. Maybe make a peace sign or a Vulcan sign or something.
