The symbol (☤) the of Hermes' κηρύκειον (kērukeion "herald's staff") is used in the U. S. as a symbol of the medical field.
Actually, it should be the original, the 1-snake ⚕ Ράβδος του Ασκληπιού (Rabos tou Asklēpiou "Rod of Asclepius"), as used in the U. N.'s World Health Organization flag.

It's actually an incorrect version of the rod of asclepius, who was a Greek god of healing or something. But there should actually only be one snake, coz with two it means something else.
