In North America, there are calls to clarify the symbol and to move to a uniform use of the rod of Asclepius. For example, the director of communications of the Minnesota Medical Association is quoted as saying, "If it's got wings on it, it's not really the symbol of medicine; some may find it hard to believe, but it's true. It's something like using the logo for the National Rifle Association when referring to the Audubon Society".[23]
