Etymology: "Hypnotoxin" is a technical coinage, not an ancient word. It is built from "hypno-", from Greek "hypnos" meaning "sleep", and "toxin", a term coined in the 1880s by the French chemist Armand Gautier and then borrowed into English. Together the parts describe a poison that produces a stupor or sleep-like state, which is how the sense of the word developed in medical writing. The "hypno-" element appears in several modern scientific terms, such as "hypnosis", which was popularised in the 1840s by the Scottish surgeon James Braid, who originally used the idea to explain a trance-like state. The same Greek root reached "hypnotoxin" by a much more recent route, so the word has no history older than the nineteenth or twentieth century.
