Epsom Salts

Epsom Salts

Out of curiosity, has anyone one used Epsom salts for their plants? I ran across something online about Europeans using it for decades. Supposedly it is a great way to increase minerals like magnesium for your plants. Has anyone tried it, and if so does it really help? I'm curious about trying alongside osmocote or miracle grow, but I am afraid of burning plants or something.
