The Natrum sulphuricum mental picture is gloomy, withdrawn, and heavily burdened by suppressed emotion. There is often a sadness without cause, especially in the morning. [Kent] describes a state where the patient is “cheerful externally but suicidal within.” Grief and hurt are deeply internalised. Suicidal thoughts may occur, particularly in the morning, but the person avoids speaking of them. There is often a history of head injury with subsequent change in personality—becoming more morose, indifferent, or irritable. [Clarke] observes aversion to company, even of family, with desire to be left alone. Oversensitive to reprimand. May be extremely conscientious, particularly about social or spiritual duties, but feel internally conflicted.
Sleep
Sleep disturbed by cough or wheezing. Wakes unrefreshed, especially between 4–6 a.m. Dreams of falling, drowning, or death. Sleep talking in anxious children. Somnambulism in emotionally burdened adolescents.
Dreams
Grief-laden dreams; dreams of falling, suffocating, or being trapped. Recurring themes of loss, death, or guilt. May dream of water, drowning, or being submerged—reflecting damp aggravation and emotional heaviness.
Generalities
A deeply sycotic remedy with powerful modalities of damp weather and early morning aggravation. Tendency to suppress emotion leads to asthma, liver disease, spinal pain, and bilious affections. Acts especially well in patients living in damp, marshy, or coastal environments. Characteristic greenish discharges and symptoms following head injury or suppressed gonorrhoea.
Fever
Chill in damp weather, followed by heat and sweating. Sweating relieves heaviness. Fevers after suppressed eruptions or emotional traumas. Alternate chills and flushes. Better in dry warmth.
Chill Heat Sweat
Chill from damp air. Heat mostly internal, especially chest and head. Sweat profuse and cold in the morning. Offensive night sweats. Sweating of scalp or face during sleep.
Head
A key remedy for headaches following head injury. [Hering] states it has “marked action in the after-effects of concussion.” Pain is typically in the occiput or forehead, worse in the morning and in damp weather. Sensation as if the brain were loose or floating. Pressure as if the skull would burst. Dizziness on rising. Mental dullness accompanies headaches. Often associated with sluggish liver or indigestion. Better from pressure or tight wrapping.
Eyes
Smarting and lachrymation in morning. Yellow or greenish discharge from canthi. Eyes weak and sensitive to light. Vision blurs after reading. Ailments from exposure to damp air. Conjunctivitis with thick, yellow crusts on lids. Chronic catarrh of the eyes in patients living in damp dwellings.
Ears
Roaring and humming in ears. Hearing impaired from old catarrh or suppressed gonorrhoea. Pain behind ears in damp weather. Ear discharge thick, yellow, and offensive. Worse on waking. Otitis media in children with asthma.
Nose
Coryza in damp weather with thick, green or yellow discharge. Nose blocked in the morning. Sneezing on waking. Nasal polyps in sycotic constitutions. Post-nasal drip that worsens asthma. Loss of smell with chronic catarrh.
Face
Sallow, earthy, or blotchy complexion. Puffy under the eyes. Acne or eruptions around mouth and chin. Cold sweat on face in the morning. Neuralgia from damp exposure. Warts or greasy skin in seborrhoeic patients.
Mouth
Tongue coated greenish or brown, especially at root. Mouth dry in morning. Taste bitter or metallic. Ulcers on tongue or cheeks. Cracks in corners of mouth. Excessive salivation. Speech sluggish after waking.
Teeth
Toothache from damp and cold air. Gums spongy and bleed easily. Teeth feel too long. Pain worse from cold food and drinks. Sycotic dental caries. Night-time grinding in anxious or emotionally repressed patients.
Throat
Soreness and rawness in the morning. Mucus in throat difficult to hawk. Worse from cold drinks and damp air. Hawking of thick, yellow phlegm. Irritation with cough and a desire to clear throat constantly.
Chest
One of the most important remedies for asthma, especially when worse in damp weather or in the early morning hours. Patient may sit up to breathe. Cough with greenish or yellow expectoration. Rattling in chest without expectoration. Stitching pains on deep inspiration. Wheezing and oppression of chest after emotion or suppressed eruptions. [Boericke]
Heart
Palpitations during menses or after grief. Stitching pain near heart on inspiration. Weakness of heart in damp conditions. Heart symptoms with mental depression and suicidal thoughts.
Respiration
Difficult, oppressed breathing in damp, low-lying areas. Must sit up to breathe. Exertion aggravates. Breathlessness with greenish sputum. Asthma worse in morning or from weather changes. Cough with thick mucus worse on rising.
Stomach
Bilious vomiting. Nausea in the morning, with headache. Pain in stomach worse after eating. Desire for sweet or fizzy drinks. Flatulence, with bloated abdomen. Symptoms follow grief or emotional shocks. Heartburn after sour food.
Abdomen
Liver region sore, enlarged, and sluggish. Pain in left lower abdomen with rumbling and flatulence. Jaundice after exposure to damp. Colic worse at night and during damp weather. Constipation alternating with diarrhoea. Abdominal complaints linked to asthma or chest congestion. [Clarke]
Rectum
Green, watery diarrhoea in the morning, especially on waking or after rising. Urging accompanied by spluttering flatus. Sudden, gushing stool. Alternates with hard, dry stool. Diarrhoea after fruit or cold drinks. Flatulence excessive and offensive.
Urinary
Frequent urging, worse in damp weather. Urine greenish or dark, with sediment. Painful urging with small quantities passed. Burning at neck of bladder. Wetting the bed (enuresis) in emotional children, especially those with asthma. Worse in early morning.

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.
