NATRUM PHOS or sodium phosphate regulates the acid/alkaline balance. Catalyses lactic acid and fat emulsion. As a biochemical antacid it regulates the acid-base balance in the stomach. Use Nat Phos when symptoms of acidity are present such as dyspepsia, digestive upsets, and heartburn. Another key function of Nat Phos is its ability to help in the assimilation of fats. Nat Phos is the principal remedy for ailments arising from an acid condition in the blood, such as rheumatism. It also acts upon the bowels, glands, lungs, and abdominal organs to bring the system back into balance. Imbalance is indicated by a coated tongue, itchy skin, sour stomach, loss of appetite, diarrhea and flatulence.
