Invented in the late 1840s, Ferric subsulfate solution is a styptic agent used after superficial skin biopsies. As a matter of fact, it is often used by Jewish burial societies to stop post-mortem bleeding, considering Jewish burial does not allow any external skin adhesives such as bandages, tape, glue or resin. For more severe cases, such as arterial lines, if the line is still inside, the solution can also be inserted directly into the IV line. Bear in mind that the use of Ferric subsulfate solution may cause vaginal pain if leakage of this solution occurs. A case report also describes use following a miscarriage. Fortunately, though, fertility was not impaired and a successful pregnancy occurred 7 months later. As for the side effects, they can include wheezing, chest tightness, fever, itching, bad cough, blue skin color, seizures, or swelling of face, lips, tongue, or throat.
