Ipecac Opium

"Dover Powder"

Named from Doctor Thomas Dover, an English physician of the eighteenth century who first prepared it, the powder was an old preparation of powder of ipecacuanha (which is currently used to produce syrup of ipecac), opium in powder, and potassium sulfate. The powder was largely used in domestic practice to induce sweating, to defeat the advance of a "cold" and at the beginning of any attack of fever. It was also known by the name pulvis ipecacuanhae et opii. - Dover's Powder on Wikipedia
