Ole Injun
Ole Injun was an alleged medical product, a "system tonic", marketed on 19th century Earth. It was said to be produced by Dr. Haile and help with the kidneys, liver, and stomach. 

A drug broker in San Francisco advertised the product in their window in 1893, their advertisement containing a picture of an American Indian in traditional garb. ()
