I picked up a couple of bottles at $3.49 a pop. The total was $7.96(including Taxes). Each bottle contains 250g of Epsom Salts
. The bottle states "Laxative/purgative for relief of occasional constipation," so I am assuming that it is likely contaminant free as it has been bottled for internal consumption. The brand name is Rougier (www.rougier.com). The DIN number is 00485853. This may be useful if you want to phone Shopper's Drug Mart ahead of time to see if they stock it. I don't know if all the Shopper's Drug Mart's carry it. At lunch time, I took a walk to a Shopper's Drug Mart close to my workplace to purchase some as I assumed if one Shopper'd Drug Mart carried it, then every Shopper's Drug Mart would carry it. Much to my surprise The Shopper's by my workplace no longer carried these and I had to purchase from a Shopper's next to my home. Hope this info helps those residing in Canada who are trying to locate a pure form of Epsom Salts
for their flusn.
