Through the centuries, people believed in medicating themselves. Sometimes the medicine worked, such as the anti-malaria tree bark extract Quinine. Sometimes the medication did harm, such as the swallowing of quicksilver (liquid mercury). But most of the time the medications were “neutral,” being neither good nor bad in the medical sense. They were placebos which most people at one time thought were lifesavers.
Much of this “neutral” medication, commonly used over much of the past 1000 years, was made from human flesh and blood. This became known as “corpse medicine,” but ended up being little more than a fast and easy way to convert to cannibalism. Unbelievably, many people still believe in such medicine today, especially if it makes them rich.
