I have been having heart palpitations for a few months now. I thought caffeine was causing them and cut it out of my diet completely. Didn't solve the issue. I also tried various magnesium supplements, which gave me diarrhea and didn't stop the palpitations. About a week ago I decided to try magnesium chloride which I had bought a few months ago at an aquarium supply store but never used. I made up a 50/50 magnesium oil solution by adding 1 cup of boiling water to 1 cup magnesium chloride crystals and stirring until the crystals dissolved. After the oil had cooled, I slathered about 3 tablespoons of the oil all over my chest and also on my right armpit. I then put on an oversized, button down shirt, leaving it wide open at the top so the magnesium oil wouldn't get soaked in the cloth, and waited about 15 minutes before washing it off. Only 5 minutes into the treatment, I felt my whole body relax and the tense feeling I had in my chest immediately dissipated.
I have been doing this treatment twice a day now for the past 5 days and have not had any more palpitations. I feel so much better now! Hope this helps someone.
