Syrup of Black Draught was a widely distributed patent medicine used for digestive complaints, constipation, and “biliousness.” This product often came in a simple cardboard box with folded paper instructions or promotional booklets inside. It was sold in powder form and advertised as a safe and gentle remedy for both adults and children. The contents were usually made from senna, sulfur, and magnesium salts — the kind of “clean you out” medicine once considered a staple in American households.

This particular specimen includes its original labeled box, internal insert, and has retained much of its period-appropriate typography and branding.
