For years, magnesium has been used ‘off-label’ for stretch marks, muscle pain, nerve pain, and headache. With this product we added magnesium salt to our Go-To Balm (original miracle balm). Due to the properties of magnesium, this is a little ‘looser’ than our regular balm but still applies completely. Migraineurs apply to temples, neck and forehead. Restless leg?? Apply to your feet to above the ankles at night.
