Potassium Sulphate. Kali Sulphas. Potassas Sulphas.

Common Name

Sulphate of Potash.

Chemical Properties

Formula, K SO4. Occurs native in lavas, etc. Crystallizes in short, permanent, colorless four-and six-sided prisms. It is soluble in ten parts of cold and three parts of boiling water. It is insoluble in alcohol. It has a sharp, bitter, saline taste.


Pure sulphate of potash is prepared by trituration, as directed under Class VII, American Homoeopathic Pharmacopmia.

Physiologico Chemical Data

This remedy, according to Schussler, is the function remedy of the epidermis and of the epithelium. A deficiency of this cell salt causes a yellow, slimy deposit on the tongue, slimy, thin, or decidedly yellow or greenish discharge and secretions of watery matter from any of the mucous surfaces, and epithelial or epidermal desquamation. The yellowness is probably due to retrograde metamorphosis - fatty degeneration of inflammatory products and of effete epithelium, etc.

The sulphates in nature and the oxide of iron serve as oxygen carriers. If sulphate and iron oxide come in contact simultaneously with an organic substance in a state of decay they give off their oxygen, and sulphate of iron is formed thereby; this may again be decomposed by the oxygen of the air, forming sulphuric acid and iron oxide, which, under favorable conditions, become again carriers of oxygen. Similar processes may occur in the human organism. Therefore, of the sulphates, Kali suiph. probably plays an important role, because it is found in the cells and in the intercellular fluids, muscles, nerves, epithelium and in the blood corpuscles. It is the carrier of oxygen. The oxygen taken up by the iron contained in the blood corpuscles is carrried to every cell of the organism by the reciprocal action of Kali suipk. and iron. Every cell requires for its growth and development the vitalizing influence of oxygen. But its continued action oxidizes the organic basis of the cells. Hence, they disintegrate into their constituent elements.

A deficiency of Kali sulph. may, according to location and extent, occasion the following symptoms: Feeling of heaviness and weariness, vertigo, chilliness, palpitation, fear, melancholy, toothache, headache, pains in the limbs, which intermit and change location. These pains are worse in closed rooms, warmth and towards evening, and better in fresh, open air, that is rich in oxygen.

Epidermis and epithelial cells poorly fed with oxygen loosen and desquamate freely. If oxygen is brought to the suffering parts by means of Kali sulph. the formation of new cells is thereby furthered, and these hasten, by their activity, to promote the desquamation of the old ones.

General Action

It is applicable to the third stage of inflammation or to its stage of retrogression, the sulphates being characteristic products of the oxidation of tissue and the potassium having its special sphere in the solids, and the resulting salt becomes a prominent constituent of their ashes, whence we can infer its homosopathicity to the same stage. Ailments accompanied by profuse desquamation of epidermis. Yellow mucous discharges. Rise in temperature at night producing an evening aggravation. Another characteristic indication is amelioration in the cool, open air. Diseases caused by a retrocession of eruptions. To produce perspiration if Ferr. phos. fails.
