Boiron - Natrum Phosphoricum 6 X - 275 Tablets
This cell salt's primary role in the body is to decompose lactic acids. Thus its remedy, Nat phos, is very beneficial to acid-related conditions including the stiff muscles after exercise or shock (from lactic acid), 'sugar highs' in children, colic from an excess of milk, sugar, fruit or alcohol, sour vomiting, indigestion, heartburn, and greenish sour diarrhea. Over the long run, acidity can lead to headaches and nervous fatigue. Nat phos' key features of sourness, indigestion, yellow mucus and a yellow coating on the back of the tongue usually grow worse from eating bitter or fatty foods (which they crave) and from mental exertion.
