What does chlorodyne mean?
Chlorodyne was a famous proprietary patent medicine introduced in Victorian Britain and widely marketed throughout the English-speaking world. Its principal active ingredients were morphine and chloroform dissolved in alcohol, and it was promoted — most notably by the pharmacist John Thomas Davenport, who popularised it from the mid-nineteenth century — as a treatment for an astonishing range of complaints: diarrhoea, cholera, coughs, neuralgia, insomnia, and colic. Sold cheaply over the counter and even given to infants, chlorodyne became a household staple, but its potent narcotic content soon made it notorious. Cases of dependence, accidental overdose, and poisoning led physicians to condemn it, and twentieth-century drug legislation eventually removed such preparations from open sale. Today the word survives mainly as a historical term, evoking an era when powerful narcotics could be bought without prescription under reassuring trade names.
nounA proprietary patent medicine of the nineteenth century, consisting chiefly of a solution of morphine, chloroform, and other ingredients in alcohol, formerly used as a sedative and painkiller.
- A proprietary mixture of morphine, chloroform, and alcohol, sold from the mid-nineteenth century as a painkiller, sedative, and cough remedy.
"In the 1860s, a spoonful of chlorodyne was the standard household remedy for coughs, cramps, and sleeplessness."
"She dosed her fretful infant with a few drops of chlorodyne before bed, as many Victorian mothers did."
"By the 1880s doctors were warning that habitual use of chlorodyne could lead to serious addiction."
Rarely pluralised; the word is normally treated as uncountable, referring to the preparation rather than discrete units. A plural may appear only when discussing different brands or formulations.
"Chemists stocked a dozen rival chlorodynes, each claiming to be stronger than Davenport's original."
Victorian Britain's favourite cure-all mixed opium, chloroform and cannabis in one bottle — and was sold over the counter for everything from toothache to cholera.

Etymology of chlorodyne
The name chlorodyne was coined in the nineteenth century as a trade name, combining 'chloro-' from chloroform (itself from Greek chlōros, meaning pale green) with the suffix '-dyne', from Greek dynamis, meaning power or force — hence roughly 'the power of chloroform'. It belongs to the same family of coinages as other Greek-derived terms using chlor- (as in chlorophyll) and dyn-/dynam- (as in dynamite and dynamic). The word entered English purely as the brand name of the medicine, which then became genericised in everyday speech for preparations of this kind.
How chlorodyne is actually used
The word is almost entirely historical; chlorodyne is now encountered mainly in accounts of Victorian medicine, literature, and discussions of drug regulation. It carried no stigma at its height but later became associated with addiction and accidental poisoning.
Easily confused with chlorodyne
Chloroform is a single anaesthetic chemical, whereas chlorodyne is a compound patent medicine that merely contained chloroform among its ingredients.
