6) Leeches

Leeching has a long history for all kinds of ailments. The practice of bloodletting was thought to realign the body’s humors (blood, yellow bile, black bile, and phlegm). Used in an ignorant manner, leeches can harm the patient. Surprisingly, many hospitals still keep medical leeches on hand, but we don’t use them as our ancestors did. They are used when a body part needs to be reattached or for reconstructive surgery. The anti-coagulant that leeches secrete after they latch on combined with the blood-sucking action helps to prevent blood clots and veinous insufficiency in patients receiving the above surgeries.

8) Cocaine

Sold as a mild additive to give energy, cocaine was seen as a helpful (or at least harmless) ingredient for any number of medical and hygiene preparations, including cough syrup and toothache drops. It was also added to wine and is well-known to have been added to Coca-Cola (until cocaine was replaced by caffeine in 1904 amidst fears of cocaine abuse). The addictive and damaging effects of the drug were not fully understood until well into the 20th century, as “pep pills” were still in use by the U.S. military during WWII. There are legal medical uses for cocaine these days for numbing purposes, although this accounts for an incredibly small amount of the cocaine grown and distributed.
