Potassium Phosphate. Potassii Phosphas.
Phosphate of Potash.
Formula, K2 H P 04. Prepared by mixing aqueous phosphoric acid with a sufficient quantity of potash, hydrate or carbonate, until the reaction is slightly alkaline, and evaporating. It crystallizes with difficulty. It is very deliquescent; it is freely soluble in water and insoluble in alcohol.
It is prepared by trituration, as directed by the rules of homeopathic pharmacy.
Kali phos. is a constituent of all animal fluids and tissues, notably of the brain, nerves, muscles and blood-cells. All tissue-forming substances retain it with the greatest obstinacy, all nutritious fluids contain it, hence we may well conclude that it is indispensable to the formation of tissues. We know also that the oxidation processes, the change of gases in the respiration and other chemical transformations in the blood, as well as the saponifying of the fat and its further oxidation, are brought about by the presence of the alkalies, and chiefly by the presence of Kali phos. This alkaline reaction is essential to a large number of vital processes taking place in the interior, and is present, without exception, in all the animal fluids which are actually contained in the circulating system, or in the closed cavities of the body. (Dalton.) It is found that the nerves retain their vital properties for a long time and very completely in a solution of this salt. By the diminution of the excretion of Kali phos. in the urine, conditions are produced within the organism which may present many-sided resistance to the typhus-decomposing element, as well as to the extension of the typhus process. (Grauvogl.) Kali phos. is an antiseptic and hinders the decay of tissues. Adynamia and decay are the characteristic states of Kali phos.
The most important discovery of Liebig, that phosphate of potash is predominant in the serum of the muscles and chloride of sodium in the circulating blood, we have often made great use of, particularly with regard to preferring the one or the other nourishment. (Hering.) A disturbance of the Kali phos. molecules has for its results:
In the mental sphere such conditions as bashfulness, anxiety, fear, tearfulness, suspicion, homesickness, weakness of memory, depression, etc.
In the vaso-motor nerves: Pulse at first small and frequent, later retardation.
In sensory nerves: Pain with paralytic sensation.
In motor nerves: Muscular and nerve prostration to paralysis.
Trophic fibres of sympathetic nerve: Retardation of nutrition to complete cessation within a circumscribed cellular domain, hence softening and degeneration of involved nerves.
Conditions arising from want of nerve power, as prostration, exertion, loss of mental vigor, depression. According to the observations of the provers by Dr. Royal, the most prominent, persistent sensation, was prostration. This was referred to the mind, nerves and muscles. Kali phos. acts upon the brain and nerve cells, upon the corpuscles of the blood affecting the nutrition, causing irritation, slight inflammation and a certain degree of degeneration. In general, a sluggish condition of mind, which will act if aroused; also an exhausted mental condition after mental exertion or great strain. It corresponds to the hosts of conditions known as neurasthenia, in which field it has won its greatest laurels. An intense odor from all the emanations of the body is an accompaniment very frequently. It is a restorative in muscular debility following acute diseases, myalgia and wasting of muscular tissue, all dependent upon impaired innervation. Atrophic condition in old people. In cases from rapid decomposition of the blood corpuscles and muscle juice, such as haemorrhages of a septic nature, scorbutus, stomatitis, gangrenous angina, phagedenic chancre, offensive, carrion-like diarrhoea, adynamic or typhoid conditions, etc.
