Natrum Sulphuricum
Substance Background
Natrium sulfuricum is the neutral sulphate of sodium, historically known as Glauber’s salt. In crude doses it is a saline cathartic that draws water osmotically into the intestine, causing watery stools and transient dehydration. Pathophysiologically it engages hepatic–biliary and portal dynamics, influences water balance across serous membranes, and irritates bronchial and nasal mucosae in damp conditions. Hahnemann and later observers (notably Schüssler) recorded a remedy picture centred on aggravation from damp and wet weather, morning diarrhoea with gushing stools, bilious headaches, asthma in damp cellars, head injury sequelae, suicidal melancholy, and a keynote worse on rising from bed with heaviness and soreness in the hypochondria. [Hahnemann], [Hering], [Allen], [Clarke], [Schüssler], [Boger], [Kent]
Proving Information
Classical provings and clinical observations delineate: worse from damp, rainy weather and sea-air, loose gushing morning stools, brown/greenish bilious stool, pressing headache in occiput/vertex relieved by stool, asthma in damp basements, cough with green, thick, ropy sputum, pain in liver with soreness of the hypochondrium, backache worse rising from a seat, restless, hypochondriacal sadness with suicidal thoughts, and a staple indication for chronic effects of head trauma (mental dullness, photophobia, vertigo).

Remedy Essence
The Nat-s. constitution is a barometer: when the air turns wet, the whole organism saturates—lungs rattle, stools gush, liver swells, joints stiffen, and the mood sours to despair. The time is morning, especially on first rising: back catches, chest is tight with green phlegm, bowels rush, and head is heavy, bilious. The place is any cellar, marsh, seaside, foggy lane, damp house—the patient knows these locales as enemies. The colour is green: green, thick, ropy expectoration; greenish stools; greenish facial tinge in hepatic phases. The direction is right hypochondrium → right scapula (liver). The feel is sore, heavy, congested, stiff on rising yet easing after a little movement. Psychologically the cloud cover darkens the mind: gloom, irritability, even suicidal ideation, notably after head injury or long wet spells; in <a href="https://www.iqhomeopathy.com/materia-medica/sol/">sunshine, the same person may be capable, even cheerful.
Choose Nat-s. when dampness is the causation and the modality, when gushing morning diarrhoea alternates with bilious headaches, when damp asthma throws up green sputum that loosens after breakfast, when back pain is worst on first rising, when warts and moist eruptions relapse at the seaside, and when a history of head trauma leaves weather-bound depression and photophobia. In chronic care, improve housing humidity, avoid basements, dry the bedroom, time outdoor exercise to dry spells, moderate beer/fruit triggers, and support bile flow (dietary). Potency choice varies: 30C–200C for constitutional damp-axis states; 6X–12X (Schüssler) for mucosal/serous regulation; repeat morning in wet seasons with careful observation.

Affinity
- Liver–biliary–portal system. Fullness and soreness of right hypochondrium, bilious vomiting, icteric tint, clay/green stools, bitter taste, headache from liver (“bilious”); stitching to right scapula. See Stomach/Abdomen/Rectum/Heartburn. [Hering], [Allen], [Clarke]
- Intestinal water balance. Early-morning, gushing diarrhoea; driving from bed; worse damp/cold drinks; better dry warmth. See Rectum. [Allen], [Boger]
- Respiratory mucosa (damp asthma). Asthma in damp weather or cellars, green, profuse, ropy expectoration, rattling mornings; worse 4–5 a.m., worse seaside. See Chest/Respiration. [Clarke], [Farrington]
- Serous membranes & water retention. Hydrocephaloid states, anasarca with hepatic link, effusions after damp exposure; congestive headaches. See Fever/Generalities. [Hughes], [Boger]
- Head injury sequelae. Mental dullness, vertigo, photophobia, headache since concussion, mood lowness and irritability. See Mind/Head. [Hering], [Clarke], [Tyler]
- Joints, sacro-iliac and lumbar region. Backache worse on rising from seat or bed, stiffness in damp/fog, must move a little before it eases. See Back/Extremities. [Boger], [Allen]
- Skin & warts (sycotic). Moist, pruritic eruptions after damp, warts (especially flat, moist, hands/genitals), seborrhoeic patches aggravated by sea-air. See Skin. [Clarke], [Hering]
- Mind–mood (damp gloom). Melancholy worse cloudy/wet weather, suicidal thoughts (especially by shooting), aversion to life after injury or prolonged humidity. See Mind. [Kent], [Hering]
Better For
- Dry, warm weather; dry rooms; <a href="https://www.iqhomeopathy.com/materia-medica/sol/">sunshine. [Clarke], [Hering]
- Pressure and firm bandaging over sore hypochondrium; lying on right side with knees drawn. [Allen]
- Rising and moving a little after the first painful effort (back/sacro-iliac). [Boger]
- Warm clothing, dry heat, hot drinks (for chill/diarrhoea). [Clarke]
- After free stool or copious expectoration (relieves head and chest). [Allen]
- Open windows if the air is dry (not foggy). [Farrington]
- Gentle exercise when the day is fine; avoiding cellars/basements. [Clarke]
- Regular routine, orderly meals; avoiding evening snacking. [Phatak]
- Sleep on right side (liver comfort) and thin pillow (head). [Hering]
Worse For
- Dampness: rainy weather, fog, damp houses, cellars, sea-air, marshes. [Hering], [Clarke]
- Morning on first rising: back pain, stiffness, gushing stool, rattling cough. [Allen], [Boger]
- Cold drinks/ice, fruit, green vegetables, beer (bilious). [Allen], [Clarke]
- Lying on the left side (congestion), lying long in bed. [Hering]
- Pressure of tight waistbands (portal stasis), bending to tie shoes. [Boger]
- Emotions after head injury; music may aggravate gloom. [Tyler], [Kent]
- Spring and autumn change of weather; eclipses of sun (old note)—low spirits. [Clarke]
- Suppressed eruptions or perspiration by damp cold → internal congestion. [Hughes], [Hering]
Symptomatology
Mind
Gloom deepens with the clouds. In wet or foggy weather, the Nat-s. patient becomes sad, taciturn, and irritable, brooding over self-destruction; a peculiar rubric is the impulse to shoot himself or a vision of hanging, often after head injury or during prolonged damp seasons. Aversion to life, yet duty holds; cannot bear music when the sky is grey. Morose in the morning, softens as the day dries. Oversensitive to contradiction, yet secretive about symptoms; children are cross, obstinate, worse damp weather, with greenish, slimy stools and morning cough. Distinguish from Nat-m. (reserved grief, sun-aggravation, dryness), Puls. (mild, seeks open cool air), Calc. (clammy, fearful, wants eggs; not distinctly damp-aggravated), Thuja (fixed ideas, “as if brittle”, strong sycosis but less bilious). [Hering], [Clarke], [Kent], [Tyler], [Phatak]
Head
Bilious and weather-bound. Throbbing or pressing headaches in occiput/vertex with nausea, bitter taste, photophobia, and icteric hue about the eyes; worse damp/fog, morning, and after mental strain; better after stool or vomiting. Headache since concussion: dull, heavy, brain feels loose, worse rising, better lying still on the right side. Heaviness as if a weight is driving the skull downward; stitches to right scapula when hepatic. Compare Bry. (frontal, worse motion, wants pressure, dryness not damp-keynote), Gels. (dullness with drooping eyelids, not bilious), Nat-m. (bursting, sun-aggravation). [Hering], [Allen], [Clarke], [Boger]
