Explore Nat Mur No. 9, also known as sodium chloride or Natrum muriaticum, with traditional fluid-balance context, comparisons and practical label guidance.
What is Nat Mur?
Nat Mur is the abbreviated name for sodium chloride in the Schüssler tissue salt tradition. It is No. 9 in our range. You may also see the longer name Natrum muriaticum in traditional reference material.
The familiar mineral name can raise questions about ordinary salt, hydration and the other tissue salts. This guide explains those distinctions alongside Nat Mur's traditional context and the details to check on the finished pack.

Nat Mur in the tissue salt tradition
Traditional tissue salt literature places Nat Mur within fluid-balance themes. This explains the wording often used in reference books and product names, including discussions of moisture and dryness within the traditional system.
These associations describe the tradition. They do not establish that the tablets regulate body fluids, treat dehydration or reduce swelling. A traditional heading is a way of organising the literature, rather than a diagnosis or an individual treatment plan.
When learning about the twelve salts, keep the mineral identity, historical description and finished product directions distinct. The ingredient name tells you which preparation you are reading about; the label provides the details needed for that particular pack.

Tissue salts, table salt and hydration
Sodium chloride is a familiar chemical name because it is associated with common salt. A finished tissue salt tablet, however, has its own preparation method, tablet base and directions. It should not be treated as interchangeable with culinary salt.
A salt number or potency notation is not a nutritional sodium amount in milligrams. No. 9 identifies Nat Mur in this range; it does not tell you how much sodium a tablet supplies or how many tablets to take.
Likewise, the traditional phrase “fluid balance” does not make Nat Mur a rehydration product. Tissue salt tablets do not replace drinking fluids or an appropriately formulated oral rehydration preparation. If a dietary sodium restriction applies to you, check the actual product information and individual suitability rather than making assumptions from its name.
How Nat Mur differs from other salts
Several tissue salts share part of their names. Reading both parts helps distinguish the preparations:
- Nat Mur is sodium chloride.
- Nat Phos is sodium phosphate.
- Nat Sulph is sodium sulphate.
- Kali Mur is potassium chloride.
The “Nat” names above identify different sodium preparations. Nat Mur and Kali Mur share the chloride part of their names but have different full identities. They are not interchangeable, and this comparison is not a recommendation to combine them.

Check the preparation strength, tablet count, full ingredients and directions. The current individual product description does not specify its dilution or complete tablet base. We do not infer those details from another brand or format.
If you avoid lactose, dairy or another ingredient, check the current pack. A mineral name alone does not describe everything in a tablet. Contact us before ordering if you need a label detail confirmed.
Follow the amount, frequency and method on the finished 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 unexplained symptoms deserve individual assessment.

Nat Mur questions answered
What is Nat Mur?
Nat Mur is sodium chloride in the Schüssler tissue salt tradition. It is No. 9 in our range and is also known as Natrum muriaticum.
What is Nat Mur traditionally associated with?
Traditional tissue salt literature associates Nat Mur with fluid balance. This is a historical theme, rather than evidence that the tablets treat dehydration, swelling or a medical condition.
Is Nat Mur the same as table salt?
Sodium chloride is the chemical name associated with common salt, but a finished tissue salt preparation has its own preparation method, tablet ingredients and directions. It is not interchangeable with culinary salt.
Can Nat Mur replace a rehydration drink?
No. Tissue salt tablets should not be used as a substitute for fluids or an appropriately formulated oral rehydration product.
Is Nat Mur the same as Kali Mur?
No. Nat Mur is sodium chloride and Kali Mur is potassium chloride. The shared Mur abbreviation does not make the preparations interchangeable.
Does No. 9 mean nine tablets?
No. It identifies Nat Mur in this range. Follow the amount, frequency and method of use on the finished pack.
