Dr. Thomas' Eclectric Oil

Dr. Thomas' Eclectric Oil (also sold as Excelsior Eclectric Oil) was pain relief remedy created by S. N. Thomas in the early 1850s. The formula was sold to the Excelsior Botanical Company in the 1880s, and shortly after to Foster, Milburn & Co., who continued to license and produce the oil into the mid-twentieth century.
