"The Smithsonian Institution began to collect objects related to health and medicine in 1881. It first obtained examples of patent medicines in 1930, acquiring packages of Haarlem Oil (or Dutch Drops), Dr. John Hooper’s Female Pills, and Roche’s Herbal Embrocation. Since then the Smithsonian’s collection of patent medicines has expanded to over 4,000 products, dating from the 19th century to the present day."

This was entered into this database in 2017, and without a date for the origin of this electronic resource, I assigned the date 2017
