I’m sorry. What the hell are you selling? Indian Blood Syrup?
Dr. Clark Johnson's Indian Blood Syrup advertisement in the Washington Post - February 3rd, 1881
Wow, this appears to cure everything.
Dr. Clark Johnson was a complete charlatan and that doesn’t even do him justice. He was a phony and snake-oil salesman. He certainly wasn’t unsuccessful hawking his wares, being quite the creative entrepreneur when it came to bilking people of their hard-earned dollars. Johnson even had a book published, detailing his years spent living among the Comanche and Apache tribes. It was a complete fabrication, meant to drum up business and give an air of authenticity, but sadly, promoted as fact and taken as fact.
