Datura stramonium — thorn-apple, one of the three great solanaceous brain remedies — is the remedy of terror. Boger's headline is definitive: "A remedy of TERRORS, BUT LACKING IN PAIN" — with "suppressed excretions", passing neither urine nor stool.
Kent opens his lecture the same way: "When considering Stram. the idea of violence comes into mind... Stram. is like an earthquake in its violence." Everything is tumultuous — "the face looks wild, anxious, fearful", the mind "in an uproar."
Yet the violence has a precise negative: absence of pain. Clarke preserves Hahnemann's own observation that Stramonium "does not in its primary effects cause actual pain", and quotes him: it "allays some spasmodic movements, and restores suppressed excretions in several cases in which absence of pain is a prominent symptom." Lippe lists "painlessness with most of the ailments" among his keynotes.
And it has a precise dependency: light and company. The patient "cannot bear solitude or darkness; must have light and company" (Boericke). These two modalities, with the terror, identify the remedy across fevers, deliria, night terrors and chorea alike.
This guide profiles Stramonium for clinical study — as recorded symptomatology for professional assessment — from Boericke's Materia Medica, Kent's Lectures, Clarke's Dictionary, Boger's Synoptic Key and Lippe's Keynotes. The originals can be read in full — Clarke's Stramonium, Boericke's Stramonium and Kent's Stramonium — through Similia's free digital materia medica.
The Stramonium State
Boericke locates the remedy's whole action in one sentence: "The entire force of this drug seems to be expended on the brain", with the skin and throat showing lesser disturbance. Clarke describes who is seized: "Ailments of young, plethoric persons; especially of children (chorea, mania, fever, delirium)."
The state is one of functional brain excitement without inflammation — Boericke: "It causes more functional excitement of the brain, but never approaches the true inflammatory condition of Bellad." Around the excitement gather the physical marks: a "red, bloated or rapidly changing face; now flushed, now pale; a sardonic grin, then expresses terror" (Boger); eyes "staring wide open; pupils dilated" with a "fixed sparkling stare"; "fine red dots on tongue" (Boger); stammering speech; "profuse sweat, which does not relieve" in violent fever.
Two systemic actions complete the ground. First, suppression: Lippe's "suppression of all secretions and excretions"; urine suppressed "with bladder empty" (Boericke); Clarke generalises it — the remedy suits "many cases of illness due to suppressed secretions... menses, lochia, sweat, eruptions." Second, abnormal movement: "increased and easy movability of the muscles subservient to the will... and slowness of the muscles not subject to the will" (Lippe) — expressed as the "graceful, rhythmic motions" and gyratory movements Boericke and Clarke both describe, through chorea and twitching of single muscles, up to "violent convulsions involving every muscle of the body, opisthotonos", covered with cold sweat — a feature Kent says "is equaled only by Camphor."
Mental and Emotional Picture
Terror with desire for light and company. The centre of the remedy. Boger: "DREADS DARKNESS, and has a horror of glistening objects. Fearful, desires company or wants to escape." Clarke's patient is "dependent on light and company; cannot walk in the dark... going through railway tunnels without a light in the carriage may cause fainting."
Night terrors. Boericke: "Awaken terrified; screams with fright." Kent gives the paediatric picture verbatim: "Child awakens terrified, knows no one, screams with fright, clings to those near." Boger: "Awakes in fear or screaming. Frightful visions."
Fear of water and of shining surfaces. "Sight of water or anything glittering brings on spasms" (Boericke). Kent: "Fear and great anxiety on hearing running water." Clarke adds the mirror: worse "by bright light, mirror or surface of water" — and Boger notes the patient "dreads water; it chokes him."
Terrifying visions. Clarke: "The delirium of Stram. is for the most part terrifying... Visions of animals enter largely into it." Kent's patient "sees animals, ghosts, angels, departed spirits, devils, and knows they are not real, but later he is confident of it. He has these hallucinations especially in the dark." Kent uses Stramonium to teach the grading itself: "An illusion is an appearance in the vision or mind which the patient knows is not true. A hallucination is a state that appears to be true. A delusion is a more advanced state, when the patient thinks it is true and cannot be reasoned out of it."
Ceaseless devout talking. Boericke: "Devout, earnest, beseeching and ceaseless talking. Loquacious, garrulous, laughing, singing, swearing, praying, rhyming." Boger records the "raving mania, with cold sweat, cursing and praying. Religious insanity" — prayer and profanity alternating in the same paroxysm.
Recorded violence. The textbooks state it plainly and so must we, as symptomatology for professional assessment: Clarke's schema records "ungovernable fury, desire to bite, to strike and to kill"; Kent's delirium "attempts to stab and bite"; Boericke lists "violent and lewd", with sexual erethism in the record. The mania is paroxysmal — Kent: "attacks of mania coming on in paroxysms, appearing with more or less suddenness."
Altered body perception. "Delusions about his identity; thinks himself tall, double, a part missing" (Boericke); "sensation as if the limbs were separated from the body" (Lippe); Clarke's sensations include "as if very tall" and "as if he had no limbs." Boger generalises: "Delusions as to size and distance" — small objects look large, "sees black."
Physical Affinities
Head and eyes
"Raises head frequently from the pillow" (Boericke) — Clarke: "Continually jerks head up from pillow; head bent back; boring head into pillow." Kent records "violent headache from walking in the sun, and from the heat of the sun", worse lying down, with the patient sitting up at night. The eyes show the remedy's photic strangeness: "Loss of vision; complains that it is dark, and calls for light" (Boericke); strabismus; and Kent's students with brain irritation from overstudy, "almost blind; there is much pain in the eyes in dim light, relieved in intense light."
Throat and swallowing
"Dry; dribbling of viscid saliva. Aversion to water... Cannot swallow on account of spasm" (Boericke); "dryness of throat and fauces, not benefited by any sort of drink" and "choking on attempting to swallow water" (Kent) — the basis of its record in hydrophobia. Thirst is violent, yet the patient dreads the very water he needs.
Convulsive sphere
"Convulsions of upper extremities and of isolated groups of muscles. Chorea; spasms partial, constantly changing" (Boericke). Lippe: "the convulsions are induced by contact, after each motion, from light and from glistening objects", and "spasm from fright." Clarke: "The twitchings of single muscles and the squint mark Stram. as the remedy for many cases of chorea... when there is fright in the causation Stram. will almost certainly avail."
Fever, skin and suppression
"Violent fever" with profuse unrelieving sweat; Boericke's skin note — "Effects of suppressed eruption in scarlatina, with delirium" — and Boger's "fiery scarlatinous rash" with "non-appearing exanthema." The bowel picture is passive amid the storm: "putrid, dark, painless, involuntary diarrhœa" (Boger). Stomach: "food tastes like straw", with vomiting of green bile — Clarke's cured case adds "vomiting of green stuff always induced by bright light."
The left hip
An oddly specific locality. Boericke: "Violent pain in left hip." Kent: "the left hip-joint is a special locality." Clarke confirms cures of coxalgia and morbus coxæ on the left, noting the severe pain here "is one exception to the 'painlessness' of Stram. affections."
Key Modalities
Worse from:
- Darkness; a dark room; being alone
- Looking at bright or shining objects — water, mirrors, glittering surfaces
- After sleep; on swallowing
- Fright; suppression; intemperance (Boger)
- The sun — headache from walking in the sun; Clarke's causation list includes sun
- Dark, cloudy days (Boger)
Better from:
- Bright light
- Company
- Warmth
The apparent contradiction — worse dark, yet spasms from glistening objects — is genuine and recorded on both sides: the patient needs steady light and human presence, but flashing, reflecting brilliance triggers the paroxysm.
Keynote Symptoms
- Terror — the face itself wears an "expression of terror"
- Cannot bear solitude or darkness; must have light and company
- Night terrors: child wakes screaming, knows no one, clings to those near
- Fear of water, of running water, of mirrors and glistening objects
- Violent, loquacious delirium — praying, singing, cursing, rhyming
- Sees animals, ghosts and spirits, especially in the dark
- Painlessness with most ailments (the left hip the recorded exception)
- Suppressed secretions and excretions — urine, sweat, menses, eruptions
- Graceful, gyratory, rhythmic movements; chorea with squint
- Spasm from fright; convulsions triggered by light and contact
- Raises head frequently from the pillow
- Stammering; cannot swallow from spasm; dread of water with violent thirst
- Sleepy, but cannot sleep
- Profuse sweat which does not relieve
Clinical Applications
The recorded territory, always within professional case management: violent delirium in continued fevers, typhoid states and mania — Kent: "It is useful in violent typhoids"; night terrors and fright-states of children; chorea and convulsions from fright, including Lippe's "certain forms of epilepsy" and "St. Vitus's dance"; puerperal mania and convulsions, where Kent directs comparison with Veratrum; hydrophobia and spasmodic dysphagia; effects of suppressed scarlatinal eruptions with delirium; delirium tremens — Boger's "wildly excited, as in night terrors or delirium tremens", Lippe's "mania, especially of drunkards"; sun headache; and ailments from shock and fright long after the event — Clarke records an extensive eczematous eruption "which came on after a fright" relieved by the remedy. Clarke's clinical list runs further through stammering, strabismus, enuresis and nymphomania — all carrying the same brain-centred signature.
Differential Diagnosis
Stramonium vs. Belladonna. The essential comparison inside the solanaceæ. Boericke: Stramonium "causes more functional excitement of the brain, but never approaches the true inflammatory condition of Bellad." Kent separates them by fever curve — Stramonium's heat "is usually a continued fever, only at times remittent, while the intense fever of Bell. is remittent always", with Belladonna's aggravation "in the afternoon and evening, 9 P.M. to 3 A.M." — and by history: in recurring paroxysmal mania "Bell. would hardly be more than a palliative in the first attack, and the second exhibition of it would do nothing."
Stramonium vs. Hyoscyamus. The third of the trio, compared without a link here. Boericke grades the fever: Stramonium "has less fever than Bellad, but more than Hyos." Kent: "Hyosc. has wild maniacal delirium, but with very little fever. In Stram. there is considerable fever." Hyoscyamus is also the more muttering, suspicious picture; Stramonium the more terrified and vociferous — and its gyrating movements are graceful where, as Clarke notes in passing, Hyoscyamus's are angular.
Stramonium vs. Aconite. Both are remedies of fright — Clarke's causation for Stramonium begins "Shock. Fright." — and both show fear with violent acute onset. Aconite's fear is the anguish of a clear-headed patient who is certain he will die, with agonised restlessness and thirst; Stramonium's is the terror of a delirious one, peopled with visions, dependent on light and company, with suppressed secretions and painlessness. After fright, Aconite meets the panic that remembers; Stramonium the night terrors and spasms that re-enact.
Stramonium vs. Opium. Boger lists Opium among the related remedies, and Clarke's comparison notes pair them twice — "Painlessness, Op." and "Sleepy, but cannot sleep, Bell., Cham., Op." Both give stupor with stertorous breathing in congestive states; Opium's is the deeper, darker painless sopor, while Stramonium keeps the terror, the visions and the desire to escape.

Anchor on the mental generals — terror, the light-and-company dependency, the specific fears — with the causation (fright, suppression) as the second pillar, then confirm with the movement disorder and the suppressed excretions. In night-terror cases the waking picture alone often decides. Our beginner's guide to repertorisation sets out the method in more detail.
