Made in the United States since 1962, Therabath is a Minnesota-based company offering kerosene heat therapy for the hands, feet, face and body. 

Therabath's parent company, WR Medical Electronic Co. was founded by 2 engineers (last names Whitson and Roth constituting "WR"). 

Both bought a company called Theratron in 1962. Theratron manufactured many physical medicine products, including what was later called Therabath. They also made kerosene wax, at the time, called Theraffin.
