Try finding Magnesium Sulfate as this is its other name. In Australia we by it at the Pharmacy or in the supermarket in the section where medicinal things such as painkillers are situated. I hope this helps. The brand I buy is Faulding Epson Salts (Magnesium Sulfate B.P.} I don't know what the B.P. stands for. Best of luck with your cleanse. Peace and good health to you.
