Saw a bottle in an antiques mall this afternoon that had what appeared to be the original cork and was filled with a solidified substance that looked like white paint. The label, which was in color and about 90% intact, said "Vanilla-Vanillin Coumarin" at the top, feature a picture of a bearded man, and had a list of the ingredients plus their percentages, but no date or dosage or statement of purpose. The main ingredient was sugar syrup (almost 50%) and there was also four percent alcohol. Can someone tell me what this was for and an approximate date?
