"Probably any chemist has Mg Cl2 Epsom Salt is the common name."
This is confusing me. I googled and saw a few sites call Epsom Salt Mg C12. But many, many sites said that Epsom Salt was Magnesium SULFATE. Are there more than one kind of Epsom Salt? I also noticed that many references said "Epson" with an "n". Is that just a confusion about the spelling or are they different substances? Maybe Epson Salt is Mg C12?
I'm pretty sure the Epsom Salt we use for the flushes is Magnesium Sulfate. Can anyone clear this up?
