Calc-Phos #2 is a cell salt that is a constituent of bones, teeth and digestive juices. Can improve digestion, help with teething and even help anemia. 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.
