Natrum Muriaticum 6X & 30: Headache, Grief, Dose

Dr. Dheeraj Sharma BHMS (Kanpur) Published August 26, 2026 Updated September 18, 2026

Natrum muriaticum is sodium chloride — table salt — used as a tissue salt and a constitutional remedy. The classical picture is a hammering headache, often from sunrise to sunset, after grief, sun or eyestrain, in someone who wants to be left alone and craves salt. A 6X tablet is nanograms of salt, not a sodium meal and not a migraine protocol.

This article is for people holding an SBL or Schwabe Nat mur 6X / 30 / 200 bottle, or searching natrum muriaticum uses. It is not a protocol for migraine with aura, hyponatraemia, or major depression.

Natrum muriaticum at a glance

What Natrum muriaticum is

Schüssler numbered sodium chloride tissue salt 9. Boericke’s monograph is larger: grief that is silent, headaches that feel like a thousand little hammers, mapped from sunrise to sunset, school-girl anaemia-headache, cold sores, a mapped tongue, craving salt, aversion to consolation.

Indian chemists sell Nat mur 6X for “colds and headaches” and Nat mur 30 for the constitutional picture. They are different dilutions of the same salt.

It is not an ORS sachet, not Slow-Sodium, and not a reason to add or ban table salt in heart failure. The arithmetic is the same family as Ferrum phos 6X: a 6X tablet holds about 60 nanograms of salt in a 60 mg lactose tablet. One pinch of dinner salt dwarfs the bottle.

What the evidence actually says

There is no reliable randomised trial showing that Natrum mur 6X or 30C prevents migraine, treats grief, shortens a cold sore, or corrects sodium.

Labels market temporary relief of headaches, heartburn and gastric upset, and print the required line: traditional homeopathic practice, not accepted medical evidence, not FDA evaluated.

Everything below is classical indication, not a trial result.

What Nat mur is classically used for

Hammer headaches. Morning, after menses, from sunrise to sunset, after eyestrain, worse sun, better sleep. Numb lips before the pain — an old aura-like line. A first thunderclap, a headache with fever and stiff neck, or a headache after trauma is not this paragraph.

Closed grief. Wants to cry alone; consolation worsens; dwells on old slights. Compare Ignatia (acute, spasmodic) and Acidum phos (flat, indifferent). Depression with hopelessness is psychiatry, not 6X. KIRAN: 1800-599-0019.

Cold sores and mapped lips. Herpes labialis sits in the old keynotes. Antivirals exist for frequent, severe, or immunocompromised outbreaks. Nat mur 30 does not replace them.

Salt craving and “dry membranes.” A craving is a keynote, not a sodium panel. Heart-failure salt limits still come from the cardiologist.

What it is not for: a sodium supplement, a hyponatraemia treatment, a thyroid drug (Boericke mentions goitre — ignore that as endocrinology), or Addison’s disease.

Nat mur 6X vs 30 vs 200

6X is not dietary salt. 30 is not stronger 6X. 30C is more dilute on the centesimal scale.

How to take Natrum muriaticum 6X

• Indian biochemic convention: about 4 tablets, three to four times a day, dissolved in the mouth, for a few days.
• Some US labels: one tablet three times a day.
• 30C: 3–5 globules, then stop when the picture eases.
• Keep 15–30 minutes off food, coffee, mint and other medicines.
• Stop if the headache is new, worst-ever, or neurological. Do not raise potency in that setting.

Keep prescribed triptans, gepants, beta blockers or antidepressants. Nat mur does not replace them.

This is not a migraine protocol and not a sodium pill

Two mix-ups.

A known migraine that matches the hammer-and-sun picture is the only setting where we still talk about Nat mur as a picture. A new severe headache is imaging and a physician.

6X cannot treat low sodium, high sodium, or heat stroke. ORS is grams of salt and glucose. This tablet is not.

Side effects — what is real

Lactose. Biochemic tablets are mostly milk sugar. See the tissue salts guide and side effects.

Nat mur compared with other remedies

When to see a doctor

Do not sit on Nat mur if you notice:

• sudden worst headache of your life
• headache with fever, stiff neck, confusion, seizure, or a non-blanching rash
• headache after a blow to the head, or with weakness, double vision, or one-sided numbness
• a new headache after age 50, or a headache that wakes you every night
• low mood with hopelessness or self-harm talk
• frequent cold sores in someone on immunosuppressants

Call emergency services (108 / 112 in India) for thunderclap headache, collapse, or a first seizure.
