2oz spray that contains Lavender Essential Oil, distilled water, and Magnesium Chloride. 
Shake well before each use, spray on the bottoms of your feet. Spray MAY tingle a bit until your body gets used to adding a new mineral. Less is more, but you can use up to 20 sprays a day. 
Please make sure you do your own research before using any natural product. Magnesium is great for many many things, while Lavender is great for sleep support, relaxation, and skin support.
