If you are following Dr. Clark's recipe, I would suggest you at least try to locate some epsom salt. Surely the country of Greece has epsom salt! Ya'll have drugstores, right? Well, then you will have epsom salt. (We have Walgreens and Walmart stores--what do you guys have?)
I bet Greece has the best olive oil in the world!!!!! Send me some. Ha
If you can't locate some epsom salt, look for magnesium citrate.
That will work.
