“…Following a definition provided by an editorial in The New England Journal of Medicine, quackery is recognized by "an ideology that largely ignores biologic mechanisms, often disparages modern science, and relies on what are purported to be ancient practices and natural remedies" [30]. Another widely used definition is "interventions neither taught widely in medical schools nor generally available in US hospitals" [31][32][33][34][35]. These definitions encompass a heterogeneous group of popular, pseudoscientific and irrational therapies such as therapeutic touch, homeopathy, herbal medicine, traditional Chinese medicine, naturopathy, reflexology, iridology, and a plethora of similar fringe practices not grounded in legitimate science [35][36][37][38][39][40][41].…”
