Ding, ding, ding....I think we have the winner!!!!!
"W. M. Wisdom, Portland, Oregon, “ Wisdom's Robertine.” Filed and recorded January 14, 1888 FROM" and was still advertised into 1920.
From that page the info is off a bit. It states "The product was first developed by W.M. Robertine of Portland, Oregon in the mid 1880s. Wisdom was a pharmacist" but Wisdom was the mans last name and Robertine the product?
