Magnesium oil can be used to treat a variety of conditions, including hair loss, eczema, wounds and burns, constipation and diarrhea. Stronger teeth and bones, less stress and a reduced chance of hypertension are also important benefits of taking magnesium. However, one of the best magnesium oil uses is to alleviate arthritis and muscle pain. The oil can be applied to any effective area and then left in place for at least several hours. It works so well because it helps to balance calcium levels in the body, and regulate muscle contractions; the result is a significant reduction in pain and less general discomfort. And that in turn can also mean a better night’s sleep for many people who are routinely kept awake with chronic pain. If you suffer from pain such as cramps or have carpal tunnel syndrome, regular magnesium intake can help you too.
