From Kook Science
The Liebig Laboratory & Chemical Works Co. was a New York-based manufacturer of patent medicines, including most famously Liebig Co.'s Coca Beef Tonic, a concentrate of beef and sherry wine with coca leaf. This company is not to be confused with the Liebig Extract of Meat Co., originators of Oxo.
