Here’s an ad from the February 27 1929 edition of the Toronto Daily Star for a herbal remedy named “Keeno”:
Apparently, Tamblyn Drug Stores were selling almost a bottle a minute of this stuff.
Google searches turned up nothing on Keeno, except for references to a couple of other newspapers from the period that also had an ad for it. The Charles Anderson mentioned in the ad might be this man, who was a Canadian politician and doctor. He served as a Conservative member of the Ontario provincial parliament from 1908 to 1914.
