Misterole

Misterole — the ointment with a name that sounds like a Victorian detective and a promise that sounds vaguely threatening: "Will Not Blister." The marketing department knew exactly what victory looked like in those days: not curing your aches, necessarily — just not making them worse.
"Better than a mustard plaster" may be the most gloriously low bar in advertising history. Misterole: because in 1915, consumer expectations were refreshingly manageable.
