Glass bottle with a glass stopper, the paper label has fallen off (see TOA0124.4).
Label says "Opodeldoc." from "George and Welch Chemists". Opodeldoc is a name given by the physician Paracelsus to a sort of liniment which he invented, or at least bestowed this name on.
Paracelsus's opodeldoc was a mixture of soap in alcohol, to which camphor and sometimes a number of herbal essences, most notably wormwood, were added. Paracelsus's recipe forms the basis for most later versions of liniment.
The name Old Opodeldoc was formerly used as a standard name for a stock character who was a physician, especially when played as a comic figure. Edgar Allan Poe used "Oppodeldoc" as a pseudonym for a character in the short story "The Literary Life of Thingum Bob, Esq." Bond's Companion to the Medicine Chest,1862,p.35-6: “ Opodeldoc. Is a valuable remedy in violent sprains and bruises, when not attended with inflammation, and it efficacy is increased when combined with a teaspoonful of laudanum to the ounce, and used as an embrocation, in rheumatic and local pains; and in colic and spasms of the bowels. It must be rubbed with a warm hand on the part affected every 3 or 4 hours till the pain abates.”
