nocebo

/nəʊˈsiː.bəʊ/
Meanings (ES + gloss)
nocebo
A substance which a patient experiences as harmful due to a previous negative perception, but which is in fact pharmacologically (medicinally) inactive.
In the case of the nocebo, it is negative expectations that become self-fulfilling prophecies.
It is somewhat surprising that little attention has been drawn to the existence of the contrary effect [to the placebo] – which I may call the nocebo reaction.
