Chloralum hydratum
Substance Background
A synthetic hypnotic/sedative introduced in the 19th century and widely employed for insomnia, delirium tremens, and convulsive states. Toxicologically it depresses the cerebrum, vaso-motor and cardiac centres, producing sopor, flushed head with cold extremities, irregular/weak pulse, respiratory depression, and skin eruptions (especially urticaria and pruritus). The homœopathic preparation is made by dilution and potentisation from the crude drug. The proving and rich clinical record yield a picture centred on insomnia with cerebral excitement, night terrors, terrible dreams, pruritic eruptions, and cardio-respiratory weakness with vaso-motor instability. [Clarke], [Allen], [Hughes], [Boericke]
Proving Information
Proving data (Allen, Hughes) plus abundant toxicological and clinical confirmations: insomnia despite fatigue, terrifying dreams with startings from sleep, night terrors of children, delirium tremens with red hot face and cold extremities, urticaria/pruritus (worse warmth of bed), irregular weak pulse, sighing/sterterous breathing, and collapse. [Allen], [Hughes], [Clarke], [Boericke], [Hering]
Remedy Essence
Chloralum hydratum is the night-panic and hot-head–cold-limb remedy. Its essence is a drug-state where the brain cannot release itself to sleep without terror: the moment of dropping off triggers images, startings, gaspings, and heart-irregularity. The skin burns and itches, the room is too warm, the face is scarlet, the hands are cold, and the pulse wavers. Around this pivot are urticaria, jactitations, sighing/stertor, and a tendency to collapse in the small hours. The modalities are tight and practical: worse at night, warmth of bed, lying flat, alcohol, sudden stimuli; better cool, uncovered head, propped, quiet companionship, and small regular sips. Distinguish from Opium (heavy stupor without fear) and Coffea (bright wakefulness without terror); choose Chloral when fear on falling asleep + pruritic heat + weak pulse entwine. Cure is recognised when sleep begins quietly, the images stay out, the pulse steadies, and the skin stops shouting. [Clarke], [Allen], [Boericke], [Hughes], [Farrington]
Affinity
- Cerebrum & sleep centres. Insomnia from cerebral excitement, sleeplessness with terrible dreams, night terrors (children), somnambulism, startings on falling asleep; sleep that does not refresh. See Mind/Sleep. [Allen], [Clarke], [Tyler]
- Vaso-motor & heart. Flushed, hot head with cold extremities; face suffused; weak, irregular pulse; tendency to collapse, syncope on rising, and cardiac depression. See Heart/Generalities. [Hughes], [Boericke], [Clarke]
- Respiration. Sighing, stertorous or irregular breathing, oppression at night, threatened apnœa in sleep with sudden start and gasp. See Respiration/Sleep. [Clarke], [Hale]
- Skin. Urticaria, intolerable itching as if skin were scalded, eczema-like eruptions; worse warmth of bed and scratching. See Skin/Generalities. [Allen], [Clarke], [Boericke]
- Nervous system. Trembling, jactitation, choreiform twitchings during sleep; alternating excitement and depression; neuralgia of head/face with congestion. See Head/Extremities. [Allen], [Hering]
- Mind (toxic delirium). Hallucinations, fear, panic at night, delirium tremens; alternating laughter and tears; confusion on waking. See Mind. [Clarke], [Tyler]
- Gastro-intestinal mucosa. Nausea, vomiting, gastric burning in over-dosed states; appetite capricious; thirst for small sips in collapse. See Stomach. [Hughes], [Allen]
Better For
- Cold applications/air to the hot head and pruritic skin; cool room improves sleep. [Clarke], [Boericke]
- Propped-up posture in bed; head high for breath and heart comfort. [Clarke]
- Gentle persuasion/soothing company in night terrors and delirium tremens. [Tyler], [Clarke]
- Quiet, darkened room (after the start of the attack) to reduce sensory storms. [Allen], [Clarke]
- Slow, steady sips (warm or neutral) in faintness; small, frequent nutrition. [Hale], [Nash]
- After a brief doze once the terrors pass; short naps restore tone. [Clarke]
- Cool sponging for flushes and itching. [Boericke]
- Uncovering the hot head while keeping limbs lightly covered. [Allen]
- Regular routine (fixed times for bed/food) eases recurrent insomnia. [Farrington]
- Open window at night if not draughting directly on the patient. [Clarke]
Worse For
- Night, especially before midnight; on falling asleep (starts, terrors, dreams). [Allen], [Clarke]
- Warmth of bed and over-heating—itching and rash blaze up. [Boericke], [Allen]
- Emotional excitement, fright, alcohol; delirium tremens setting. [Clarke], [Hughes]
- Lying flat; respiration and heart feel oppressed; snoring with threatened apnœa. [Clarke]
- Sudden noises or light when dosing; precipitate startings and panic. [Allen]
- After overwork and long watching; neurasthenic insomnia. [Tyler], [Nash]
- Scratching—itching spreads; skin burns as if scalded. [Allen], [Boericke]
- Warm rooms, feather beds, close curtains. [Clarke]
- On rising suddenly—giddiness, faintness, irregular pulse. [Hughes], [Clarke]
- Suppression of eruptions—restlessness, insomnia, and heart symptoms intensify. [Clarke], [Farrington]

Head
Congestive headaches with hot, flushed face and throbbing carotids; head feels heavy, bursting, especially frontal and temporal, with cold hands and feet (vaso-motor inversion). Motion, warm rooms, and mental exertion aggravate; cold applications, fresh air, and darkness relieve (10a/10b). The headache escorts the insomnia and itching, peaking at night, easing toward morning. Neuralgic streaks pass along the trigeminal branches during congestive flushes; the scalp feels tender and itchy; hair-brushing is disliked. In toxic states there is giddiness on rising, tendency to sway, and a sense of sinking at the occiput; eyes feel heavy and lids droop. Recovery of the head accompanies improvement in sleep and pulse steadiness; a relapse of heat/itch warns of a new restless night. [Clarke], [Allen], [Hughes], [Boericke]
