Nat-Phos #10 is an acid neutralizer. It emulsifies fatty acids and keeps uric acid soluble in the blood. Uric acid can become solid and then you can have gout. It is also good for heartburn and any digestive disorder including jaundice (a liver condition). 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.
