The sign, however, is often conflated, especially in the United States, with the Caduceus, a symbol of Apollo—his father, two winged snakes in a helix, like DNA, due to the singular insistence of one unit commander of the US army's cadet medical enterprise who was convinced he was correct and that two snakes were better than one and looked a bit better as a unit badge. The emblem of Asclepius himself is of uncertain origins and may represent the dual nature of medicine, with either the ability to support in the right doses or toxic when dispensed too freely, and indeed, supplicants who went to places sacred to Asclepius to be healed found themselves in a den of non-venomous serpents and is immortalised in the night-sky in the constellation Ophiucus, the snake-handler. Some think that the mistaken Caduceus is a perfectly valid symbol, ironically, for modern medical practises, as Apollo was basically the traveling salesman of the gods and sold a good line—rather the ambulance-chaser instead of the ambulance, and possibly an inherited-trait.
