Why did they stop making internal liniment?

Answer 1

The production of internal liniment was halted due to safety concerns and the potential for misuse. These products often contained ingredients that could be harmful if ingested or improperly applied, leading to serious health risks. Additionally, advances in medical understanding and the development of safer, more effective alternatives diminished the demand for such products. Consequently, regulatory agencies also began to impose stricter guidelines on their formulation and distribution.
