Natrum Sulphuricum

An inorganic compound composed of sodium and sulphuric acid (Na₂SO₄). Occurs naturally in saline springs and as the mineral mirabilite.

Traditionally used as a saline laxative and in detox therapies; also employed industrially in glass manufacturing, dyeing, and paper processing.

First proved by Dr. J.J. Garth Wilkinson and later extensively used by Kent, Clarke, and Hering; deeply confirmed through clinical practice

• Liver and portal system – detox, congestion, sluggishness
• Head – especially from head trauma or emotional trauma
• Lungs – asthma, damp aggravations
• Digestive system – bilious complaints
• Spinal cord and meninges – old injuries, suppressed inflammation
• Left lower quadrant of abdomen

• Dry weather and open air
• Pressure (abdominal pains)
• Changing position
• Warmth of bed (some symptoms)
• Motion (for chest symptoms)
• Passing stool or flatus

• Damp, wet weather
• Living near the sea or marsh
• Morning, especially 4–9 a.m.
• Lying on left side
• Mental exertion or suppression
• After injury to the head or spine
• Cold drinks and sour food

• Thuja – Both sycotic, but Thuja is more secretive and fixed; Nat-s. more emotional and asthmatic
• Pulsatilla – Also green discharges and emotional grief, but Puls. is weepy and open; Nat-s. more closed and suicidal
• Natrum muriaticum – Both internalise grief; Nat-m. is more intellectual, Nat-s. more depressed and suicidal
• Causticum – Sad, sympathetic, but Caust. has more paralysis and vocal weakness
• Kali sulphuricum – Also yellow discharge and asthma; Nat-s. more sensitive to damp, Kali-s. to stuffy warmth

• Complementary: Natrum muriaticum, Pulsatilla
• Antidotes: Nux vomica, Camphora
• Follows well: Thuja, Silicea
• Precedes well: Sulphur, Lycopodium

Natrum sulphuricum centres around the suppression of emotion, particularly grief and disappointment, combined with an environment of dampness and heaviness. The patient feels burdened, suicidal in the morning, yet hides their suffering. Asthma, bilious troubles, and headaches arise from both environmental and emotional sources. It is especially suited to those who carry inherited disease miasms, worsened by environment and suppression.

• Excellent for asthma in damp weather, especially morning aggravation
• Suicidal depression worse on waking—ask about head injury history
• Important in congenital sycosis with inherited skin/lung issues
• Helps chronic liver disease in melancholic, withdrawn patients
• Think of it in spinal meningitis or post-concussion syndrome

Mind

• Suicidal in the morning
• Sadness, silent grief
• Ailments from head injury
• Aversion to company

Head

• Headache, occiput, damp weather
• Head injury, after-effects

Chest / Respiration
