In this article, you state that magnesium sulfate has been shown to be effective in treating eclampsia. It also has been studied and apparently is effective in stopping some brain damage from stroke. I am wondering why the cost and availability of this drug is such a problem for poor countries. The last I checked, magnesium sulfate could be purchased in every grocery store as Epsom salts, for about $1 per pound.
