Kali Sulph in the tissue salt tradition
Traditional tissue salt literature places Kali Sulph within skin and mucous-membrane themes. “Skin balance” is a familiar descriptive heading used for this preparation and explains some of the language you may encounter in reference books and product names.
These associations describe the traditional framework. They do not establish that the tablets treat a skin condition, stimulate hair growth or renew cells. A historical heading helps organise the literature, rather than providing a diagnosis or an individual treatment plan.
For anyone learning about the twelve salts, it is useful to separate three things: the mineral name, the traditional description and the directions for the finished preparation. Each tells you something different, and none should be inferred from the others.

How the similarly named salts differ
Kali Sulph shares part of its name with several other tissue salts. Reading both parts helps distinguish the preparations:
- Kali Sulph is potassium sulphate.
- Kali Mur is potassium chloride.
- Kali Phos is potassium phosphate.
- Calc Sulph is calcium sulphate.
- Nat Sulph is sodium sulphate.
The three “Kali” names identify different potassium preparations. The “Sulph” names above share the sulphate part but have different full identities. Similar spelling does not make them interchangeable.
Use this comparison as a guide to reading labels and exploring the library. It is not a recommendation to combine the salts or select a preparation based on a symptom alone.
Reading a Kali Sulph label
The salt number, preparation strength and tablet count describe different features. No. 7 identifies Kali Sulph in this range. A potency or dilution notation describes the preparation, while a tablet count tells you how many tablets are supplied.
No. 7 does not mean seven tablets. Neither the salt number nor a potency notation is a nutritional potassium amount in milligrams. A tissue salt should not be assumed to provide a dietary dose of potassium or used to correct a potassium deficiency.
The current individual product description does not specify the complete tablet base or dilution. Check the finished packaging, or ask us to confirm those details before ordering. Do not assume that another brand or format uses the same preparation.

Read the full ingredients, including the tablet base and any allergen information. If you avoid lactose, dairy or another ingredient, the mineral name alone cannot establish whether a finished tablet meets your needs.
Follow the amount, frequency and method on the pack, including any age guidance. Check individual suitability with an appropriate practitioner during pregnancy or breastfeeding, when taking medication or when choosing for a child. Persistent or worsening skin symptoms deserve individual assessment.
Store tightly closed in a cool, dry place away from sunlight and heat. Keep out of reach of children, and retain the packaging so that the directions and batch details remain available.
