Why “nocebo” is a great word
A pharmacologically inert substance or treatment that induces adverse effects in a patient solely through the power of negative expectation. From Latin nocēbō ("I will harm"), the future active indicative of noceō ("to harm"), by analogy with placebo; coined in 1961 by Walter P. Kennedy. Unlike "placebo" (which heals through hope) or "iatrogenesis" (which implicates clinical error), nocebo operates through the mind's capacity for self-sabotage. It is the anticipatory nausea before chemotherapy, the headache that blooms after reading a drug's side-effects leaflet, or the very real rash that appears where a patient was merely told an allergen touched the skin—a stark testament to the body's terrible talent for materializing its own fears.
Etymology
Borrowed from Latin nocēbō (“I will harm”), the first-person singular future active indicative form of noceō (“to harm”), by analogy with placebo. The word was coined by Walter P. Kennedy in an article entitled “The Nocebo Reaction” (1961). (see quotation).
