Mercurial Therapy

Historical and Premodern Treatment Practice

Mercurial therapy was the historical use of mercury compounds, taken by mouth, rubbed into the skin as an ointment, or inhaled as a fumigant, most notably as the standard treatment for syphilis from the sixteenth century until the early twentieth. Physicians administered mercury on the belief that it could purge the disease from the body, despite the severe toxicity that came with prolonged use, which gave rise to the grim contemporary saying that a night with the goddess Venus meant a lifetime with the god Mercury. The treatment began to give way after German physician Paul Ehrlich and his collaborator Sahachiro Hata introduced arsphenamine, the arsenic-based compound marketed as Salvarsan, in 1910, and mercury-based syphilis treatment was finally displaced entirely once penicillin proved effective against the disease in the 1940s.
