Language keeps changing. We used to call questionable remedies “folk medicine,” “fringe medicine,” or “quackery.” In the 1970s, the term “alternative medicine” was coined, an umbrella term for all treatments that were not supported by good enough evidence to have earned them a place in mainstream medicine. Then came “complementary and alternative medicine” (CAM), and later, “integrative medicine.” Now there’s a new kid on the block, “functional medicine” (FM) which is really just the latest flavor of integrative medicine. These are all marketing terms, Trojan horses designed to sneak non-science-based medicine into conventional medical practice. The oft-quoted quip is appropriate here: Do you know what you call alternative medicine with evidence? Medicine.
