The caduceus is associated with commerce, not medicien: Caduceus
Actually, I meant the caduceus. In America, at least, today, the caduceus is the symbol of medicine. It doesn't matter that once upon a time, it had to do with commerce; today, in this place, it means medicine. I was a Hospital Corpsman in the US Navy, and my rate mark was a caduceus. My father was a Registered Nurse, and had a caduceus engraved on his stethoscope. So it's a symbol which has deep personal meaning for me, and it's the one I'll use.
