Step right this way, friend, and behold the next selection from the Pennsylvania Lumber Museum’s patent medicine collection. While this tonic does fall under the category of patent medicine since it was made before any regulation, and the box does say it is registered with the patent office, it does differ in that it could have been effective. One of the listed uses was as a Malarial tonic, and Quinine is an effective treatment for malaria.
The box describes this tasteless syrup as “It is Pleasant to the taste. CHILDREN LIKE IT”. Which begs the question of how something tasteless has a pleasant taste? (L73.18.1 A,B)
