Кто первым ввел термин "плацебо"?
The first to recognize and demonstrate the placebo effect was English physician John Haygarth in 1799. He tested a popular medical treatment of his time, called "Perkins tractors", which were metal pointers supposedly able to 'draw out' disease. They were sold at the extremely high price of five guineas, and Haygarth set out to show that the high cost was unnecessary. He did this by comparing the results from "dummy" wooden tractors with a set of allegedly "active" metal tractors, and published his findings in a book "On the Imagination as a Cause & as a Cure of Disorders of the Body".
