You make a good point and that makes sense. However, I am unaware of any case where Epsom Salts have inflicted damage on a human being. There are people that have successfully completed as many as 80+ flushes using Epsom Salts as per of the Liver Flush Protocol. You say that just because something is beneficial for plants does not mean that it is not toxic for humans. Yes, you are right. But this does not appear the case for Epsom Salts . Epsom salts that appear to be beneficial for plants have not been found to be harmful to humans. Not trying to be hateful, but pointing out an established fact.
