I make magnesium oil out of these flakes by adding pure water to them. Then, after each meal, I put one or two drops of magnesium oil on my body as a way to take in magnesium that has been otherwise difficult for me to get in my diet. But, there is a catch. When I would put magnesium oil on my body in the same spot each day, it would burn. So, I learned to rotate the spots on my body where I would apply the magnesium oil. I also found that if I allowed 36+ hours between applications on the same spot, then it wouldn't burn.The spots that I find work the best are the back of my hands, my wrists, the back of my knees and the tops of my feet. I usually do one or two spots after each meal, as long as I've had enough raw vitamin A in that meal. But, not just any old vitamin A. It has to be vitamin A found in raw butter, raw egg yolks, raw cream or raw beef liver. Those are the only vitamin A sources that would work to uptake the magnesium in my body. Otherwise, my glaucoma would act up because of the excess free-floating magnesium in my body. Same with when I eat cheese. The calcium in the cheese will burn my eyes if I don't have enough raw vitamin A in the same meal.
