With the sudden cool and wet weather around here this weekend, seems may people have a case of the sniffles. It's probably not a "cold" in the sense of a rhinovirus infection, and pollen levels are low; but the body can have a reaction to climatic factors that looks pretty damned similar. (There's a fancy word for it: vasomotor rhinitis, which means nothing more than "inflammation inside your nose from blood vessels opening up.") Chinese medicine, though, doesn't really care if there's a virus, allergen, or environmental factor involved; it's interested in how your body is responding.
Try the following acupressure points. Apply pressure slowly and gently. Poke around in the general area indicated to find the point that feels most responsive. If it hurts -- don't do it.
