Important: Safety Warning

This page recommends preparations containing opium, laudanum, morphine, or similar narcotics — in some cases for children. These substances are dangerously addictive, easily fatal in overdose, and strictly controlled by law today.

In addition, this page describes trade processes that use dangerously toxic materials such as cyanide solutions, mercury amalgams, or strong acids. These processes require training, equipment, and precautions far beyond what the text describes.

In addition, this page presents medical treatment from an era before modern medicine. The remedies described are ineffective against the conditions named, and some of the ingredients or doses are harmful. Do not use them to treat any illness; consult a qualified medical professional.
