The following symptoms of Natrum phosphoricum are collected from nineteen provings made by twelve provers; nine males, three females. The potencies range from the 6th to the 100,000th. The first provings made in 1869, the last in August 1875….

Synonyms: Phosphate of Soda, Sodi Phosphas, Sal Mirabile Perlatum, Alkali Phosphorus, Tasteless Purging Salt., etc.

The Phosphate of Soda exists in minute proportions in all solids and fluids of the body. Like all the alkaline Phosphates, its quantity is greater in flesh-eating animals.

Its function in the blood is not conclusively known; but it has been recently demonstrated that it conveys carbonic acid fro tissues to lungs. If this is so, it must have a nutritive value, and is well-worthy of a therapeutics study. Schussler, so impulsive in therapeutics, is an excellent student of Physiology. According to him, it plays an important part in the lymphatic system; hence in the blood genesis.

In 1800, Dr. Person introduced this Salt into Allopathy. He considered it a mild purgative, suitable to children, and persons of a delicate stomach. It has sometimes been given medicinally by substituting it for common salt.

Dr. William Stephenson (Edinburgh Medical Journal, 1867, Vol xiii, p. 336) recommends it for “infants who are being artificially reared, and who are liable to frequent derangement of the bowels…. where, from the character of the motions, there is a deficient or defective secretion of bile…. chalky stool, or white fluid motions, and in many cases of green stools”, etc.

In our school, several partial provings were made years ago by Dr.Hering. In 1873, Schussler mentioned it as a tissue remedy. Von Grauvogl lays more stress on the Muriate and sulphate of Soda, preferring the Phosphate of Potash in the saponifications of fats, change of gases, etc. as the most active. But potash salts exist more in the blood-cells, muscles, etc. soda, in the liquor sanguinis. Potash Salts, when proved, show an aggravation when awakening, that is, when we begin to use oxygen, which was stored up during sleep; Soda Salts are worse during sleep, while oxygen is accumulating (C.Hg.). Hence even though as alkalies they have many similarities, we shall find sharp differences, depending upon variations in function. Potash must be present to insure an amount of oxygen calculated to keep muscles in their full power of contraction; Soda must be present to carry away carbonic acid, a resultant of oxidation.

The following resume is collected from nineteen provings made by twelve provers; nine males, three females. The potencies range from the 6th to the 100,000th. No prover knew the name of the medicine, nor did any two have opportunities of conversing or comparing notes. In no case was a single dose given, but at least twenty were taken. The first provings made in 1869, the last in August 1875.

I am well-aware that prejudice will lead some to refuse these provings because they were made principally with the high potencies. This, however, will in no wise alter their truth or falsity. If four or more persons, in different seasons of the year and and in different latitudes, experience the same effects from any given potency, we have an indisputable right to claim these effects as resulting from the medicine taken. If only one prover develops a certain symptom, or set of symptoms, they may, be fallacious or they may be true. Who shall decide from performed opinion? The advocate of the high or of the low potencies? Neither. There is no court of appeal for the Homoeopathician but that which Hahnemann was the first to establish, viz. experiment. So with the symptoms here offered for trial. If they fail when tried, let them go. If they do not fail, let us use them, however our prejudices may question their origin.

Great care has been exercised in preparing the accompanying resume. Symptoms which had been previously experienced by the provers have generally been omitted. Something may thus have been lost, especially as illustrating the reawakening, of latent disease; but much has been gained in precision and certainty. For the same reasons obscure or indefinite symptoms have been reserved until more clearly expressed.

E. A. Farrington (1847-1885) was born in Williamsburg, NY, on January 1, 1847. He began his study of medicine under the preceptorship of his brother, Harvey W. Farrington, MD. In 1866 he graduated from the Homoeopathic Medical College of Pennsylvania. In 1867 he entered the Hahnemann Medical College, graduating in 1868. He entered practice immediately after his graduation, establishing himself on Mount Vernon Street.
