This is general information about a homeopathic remedy, not a prescription or dosing advice. In homeopathy the correct remedy and potency are chosen for the whole individual symptom picture by a qualified homeopath — the same remedy is not right for everyone. Do not self-medicate, and consult a qualified homeopathic doctor (and your physician for serious or persistent conditions) before taking any remedy.

- Acidity with sour belching or risings

Characteristic symptom picture

Potency
Natrum Phosphoricum is available in several potencies such as 6C, 30C and 200C, and in lower or biochemic and mother-tincture forms in some cases. The right potency and repetition depend entirely on the individual case and are decided by a qualified homeopath - this page gives no dosing instructions.
The Nat Phos picture and modalities
Natrum Phosphoricum is the tissue salt of acidity. Everything about its picture tends to be sour - sour belching, sour vomiting, sour sweat - with a characteristic creamy, golden-yellow coating at the back of the tongue and aggravation from fatty, sugary, and sour foods. It is also a classic name in the children's worm picture with teeth-grinding. A homeopath weighs this acidic, sour pattern within the whole picture.
Before you consider Nat Phos
This is background information, not advice to self-treat. Persistent acidity, reflux, or a suspected worm infestation in a child should be assessed medically, since these have causes that need proper evaluation and, for worms, medical de-worming. In homeopathy the right remedy and potency are chosen for the whole individual by a qualified practitioner. Homeopathy should complement, not replace, conventional care.
