GLOSSARY OF ESOTERIC WORDS
placebo
'an epithet given to any medicine adapted more to please than benefit the patient.' Placebos are now used as controls in trials of new drugs, but the original use was simply to keep a patient happy--in other words, to 'please'. Sir Walter Scott wrote in St. Ronan's Well in 1824: "There is nothing serious intended--a mere placebo--just a divertisement to cheer the spirits, and assist the effect of the waters."
