Mercury’s toxic properties have been apparent for centuries. Nonetheless, from the time of the first Emperor of China on, doctors have been fascinated with the metal’s purported curative properties. In the 19th and early 20th centuries, health practitioners blithely used mercury as a medical treatment for everything from syphilis to teething discomfort to dysentery.
As early as the 1820s, some healers began to object to the practice of “giving poison as medicine,” but, in many branches of medicine, physicians remained enthusiastic. In the late 1890s, for example, the prestigious scientific journal The Lancet published case studies broadcasting doctors’ seemingly successful use of mercury for the treatment of heart disease. Referring to a mercurous chloride compound called calomel (also called the “blue pill”), Dr. Arthur Foxwell in Birmingham praised, in September 1895, mercury’s “unique” virtues as a cardiac tonic capable of “freeing” a sluggish heart of “half its labour.”
