Epsom is a historic town in Surrey, England, famous for its mineral springs and for giving the world Epsom salts.
Epsom salt is the common name for Magnesium sulfate (MgSO₄·7H₂O), a naturally occurring mineral compound composed of magnesium, sulfur, and oxygen.
It was first identified from mineral spring waters in Epsom, which is how it got its name. In 1618, a farmer named Henry Wicker discovered it

Magnesium Sulphate: Anticonvulsant
The anticonvulsant property of magnesium sulfate was discovered in the early 1900s.
-
In 1906, Samuel J. Meltzer and John Auer at the Rockefeller Institute for Medical Research conducted animal experiments.
-
They demonstrated that magnesium salts could suppress neuromuscular transmission and prevent convulsions in experimental animals.
Early clinical use in obstetrics was reported by J. P. Lazard in 1925, who administered magnesium sulfate to control eclamptic convulsions.
J. P. Lazard an American obstetrician in Los Angeles, California, known for pioneering the use of Magnesium sulfate to treat seizures in Eclampsia.
Lazard worked at Los Angeles General Hospital in California.
Lazard demonstrated that magnesium sulfate could safely control eclamptic convulsions and reduce maternal mortality. His studies included hundreds of patients between 1924–1932, showing a significant drop in death rates compared with earlier treatments.
J. P. Lazard To Jack Pritchard
Jack A. Pritchard (1915–2003) was an American obstetrician–gynecologist known for developing the Pritchard regimen for treating seizures in Eclampsia using Magnesium sulfate.
Pritchard Regimen
The MAGPIE Trial (2002) showed magnesium sulfate significantly reduces the risk of seizures and maternal death in Pre‑eclampsia.
