The two intertwined snakes, coiled around a winged rod is commonly used as a symbol of medicine, especially here in the US. But the symbol is actually mistaken from that of the Rod of Asclepius which shows only a single snake, and is the true symbol of health and medicine.
(The two-snaked rod is a symbol of Hermes, the Greek god. He was a god of everything from trade and travel to sports, thieves and the Underworld! )
However, it occurred to me that these days - with the political battle over healthcare and health rights - the two-snake version - appearing to be battling it out - is more appropriate than ever.
"Who knew" healthcare could be so complicated.
