Kalium sulphuricum
Potassium sulphate · Potassium sulfate, sulfate of potash, Vesuvian salt, glaserite. · Mineral
Kali. sulph. is most appropriate for people who tend to be conservative and anxious to do things right, down to the last detail. They are often hurried, anxious, restless, easily startled, and irritable. Dutiful in loving relationships, they may be self-sacrificial because of the connection this gives them with others.
The remedy’s classic affinities are with the skin and the respiratory system. It is commonly prescribed for peeling skin conditions such as eczema and psoriasis, and may also be appropriate for ringworm, polyps, oily skin problems, and skin cancer. The skin is characteristically chapped, scaly, or peeling, and there may be sore areas with thin, yellow, watery discharges.
Chronic respiratory problems are a further key affinity of Kali. sulph. It is used for chronic catarrh, or mucus in the nose, larynx, bronchi, or ears, and for asthma. The nose is typically highly congested, with rattling mucus in the lungs and loss of the sense of smell. There may be smelly, long-standing discharges in the ears, with frequent inflammation and glue ear.

Two very deep acting remedies unite to form this one. It was left to Schüessler to show its first curative powers.
Dewey's work, on the "Tissue Remedies" gives the best presentation from the biochemic view. The writer gathered the symptoms from reported cures for many years, and found that they were justified by the study of the two remedies entering into the formation.
Generals
Many of these symptoms come out upon the sick as aggravations. Some of these are only cured symptoms. This arrangement could be improved upon much by provings. If the reader will carefully use this remedy as herein directed he will be astonished at its depth of action, and if he uses it high he will be surprised at the length of action of every dose.

Characteristics
Schüssler's account of this remedy is as follows: K. s., which in reciprocal action with iron effects the transfer of the inhaled oxygen to all the cells, is contained in all the cells containing iron. A deficiency of K. s. causes: "A sensation of heaviness and weariness, vertigo, chilliness, palpitation of the heart, anxiety, sadness, toothache, headache, and pain in the limbs." These are < in a room; in warmth; towards evening; > in open, cool air. "There ensues a desquamation of cells of the epidermis and epithelium, which have been loosened from their connection because they were not sufficiently provided with oxygen. The scaling off of these epithelial cells is …
