Mag-Phos #8 is a nerve stabilizer (anti-spasmodic). It is found in bones, teeth, brain, nerves, blood and muscle cells. It is good for cramps, neuralgia, flatulence and colic. A German homeopathic physician, Dr. Schussler, identified 12 cell salts (mineral salts) that were all that was needed to maintain the body in perfect health and balance. A lack of a specific cell salt would result in a deficiency that would eventually lead to a symptom and possibly disease. By replacing the deficient cell salt, the balance was restored and healing took place.
