Language keeps changing. We used to call questionable remedies folk medicine, fringe medicine, and quackery. In the 1970s,the term alternative medicine was coined, an umbrella term for all treatments that were not supported by respectable enough evidence to have earned them a plot in mainstream medicine. Then came complementary and alternative medicine (CAM), or later,integrative medicine. Now there's a unusual kid on the block, functional medicine (FM) which is really just the latest flavor of integrative medicine.
