Acupuncture for seasonal allergies is an apropo subject right about now. It seems that every other person walking through my door is stuffed up and suffering. The tree pollen is flying and there's no better time for acupuncture. I like this particular study on the efficacy of acupuncture for children with seasonal allergies. The kids would have preferred medicine to needles, but they got good results with no side effects. So, the parents were happy!
