• Nervous system (hysterical/neurasthenic states). Oversensitive reflex arcs; tremors, startle, faintness; somatisation of emotion into palpitation or cramp (see Mind, Heart, Abdomen). [Hering], [Allen]
• Female reproductive organs. Amenorrhoea from cold or shock; dysmenorrhoea with hysterical paroxysms; symptoms often ease when menses flow resumes (see Female; ties to 10a “Better after discharges”). [Hering], [Clarke]
• Sleep centres. Insomnia from mental over-activity; light, easily broken sleep with startle to noises; nervous twitchings (see Sleep). [Hering], [Allen]
• Cardio-respiratory (functional). Palpitations and oppression from emotion without lesion; sighing respiration in hysteria (see Heart, Respiration). [Clarke], [Hering]
• Gastrointestinal (reflex). Nausea and eructation from excitement; flatulence and colic during emotional strain (see Stomach, Abdomen). [Allen], [Hering]
• Sensorium & special senses. Photophobia with nervous headache; acoustic hyperacusis (noise startle → palpitation) (see Head, Ears). [Allen], [Hering]
• Musculoskeletal. Tremulous weakness; cramping in forearms/calves after overuse or shocks (see Extremities). [Allen]
• Autonomic balance. Vasomotor lability—pallor ↔ flushing; chilliness after paroxysm (see Fever/Chill/Sweat; Generalities). [Hering]

• Quiet, dark room. Reduces sensory bombardment; headaches and palpitations subside (cross-ref Head, Heart). [Hering]
• Warmth generally; pelvic warmth. Soothes dysmenorrhoea and nervous chills; matches “from cold exposure” aetiology (see Female, Fever/Chill). [Allen], [Hering]
• Gentle, steady pressure. Over spasmic muscles steadies tremor (see Extremities). [Allen]
• Reassurance and gentle company. Emotional holding reduces paroxysm probability (Mind ↔ Heart), [Clinical], [Hering].
• Slow, undemanding movement. Light walking eases light-headedness versus jarring exertion (Generalities). [Clarke]
• After return of discharges. Menses or stool flowing relieves cramp, tension, and mood (Female, Rectum) — “this tallies with Better after discharges already noted.” [Hering]
• Warm drinks. Settle nausea/eructation in nervous dyspepsia (Stomach). [Allen]
• Side-lying. More comfortable than supine during fainty spells (Respiration/Heart). [Clarke]
• Rhythmic breathing exercises. Reduce sighing respiration and panic (“Mind ↔ Respiration” axis). [Clinical]
• Distraction with gentle task. Low-demand occupation counters ruminative insomnia (Sleep). [Clinical]
• Time and rest after shock. Paroxysm intensity wanes with repose (Generalities). [Hering]
• Moderate food, simple warm meals. Quiet the gut–nerve loop (Stomach/Abdomen). [Allen]

• Emotional shock, bad news, quarrels. Trigger palpitations, tremor, faintness (Mind → Heart) (Proving). [Hahnemann], [Hering]
• Suppression of accustomed discharges. Amenorrhoea/lochia/diarrhoea suppressed → hysterical paroxysm; cross-ref Female/Rectum. [Hering], [Clarke]
• Cold exposure (feet, pelvis). Leads to menstrual suppression and cramps; “from cold” aetiology signature. [Hering]
• Sudden noise/bright light. Sensory startle sets off palpitation or headache (Ears/Eyes/Head). [Allen]
• Mental overwork, late-night study. Exhausts “nervous battery” → insomnia and tremor (Sleep/Extremities). [Allen]
• Coffee, rich food. Heightens excitability; provokes dyspepsia in the exhausted (Stomach). [Hering]
• Lying supine during hysterical phase. Increases breath-holding/spasm tendency (Respiration). [Clarke]
• Crowded, stuffy rooms. Overstimulate senses; induce oppression and sighing (Chest/Respiration). [Hering]
• Abrupt cessation of routine. “Let-down” → low spirits, weakness (Mind/Generalities). [Allen]
• Menstrual anticipation. Premenstrual nervousness/insomnia intensify (Sleep/Female). [Hering]
• Overexertion after convalescence. Brings cramps/tremors (Extremities). [Allen]
• Contradiction or reprimand. Emotional sensitivity → tears/palpitations (Mind/Heart). [Hering]

Castoreum suits the oversensitive, over-wrought nervous temperament—often quiet women worn down by long anxiety or work beyond strength—where small emotional ripples become bodily waves: palpitations, tremors, faintness, abdominal cramp ([Proving]) [Hahnemann], [Hering]. Irritability at trifles alternates with tearfulness and inward sighing; the patient is “tired of being startled,” seeks a dark, quiet refuge, and shrinks from noise or rebuke (this tallies with the amelioration from quiet/dark in Modalities) [Allen], [Hering]. Unlike Moschus’ theatrical displays, Castoreum’s hysteria is subdued; “the show is in the nerves,” not on the stage—fewer fits of capering, more quiet sinking, pallor, and soft sobbing [Hering], [Clarke]. The sensorium feels overfilled: bright light is too sharp, sounds too near, and thoughts too busy; the mind fatigues quickly from reading or household accounts, then trembles within (cross-ref Sleep: insomnia from mental over-activity) [Allen]. Anxiety is often situational—anticipation before menses, fear after cold exposure, dread following family discord—each capable of precipitating palpitation or cramps (see Female, Heart) [Hering]. In neurasthenia after grief or sleepless nursing, the patient becomes indecisive, avoids decisions that might trigger an episode, and leans on reassuring company (Better for reassurance) [Clinical], [Hering]. There is aversion to crowds and an impulse to escape stuffy rooms (see Respiration: sighing, oppression) [Hering]. Case: a governess, worn by late-night lessons, developed faint spells on reproof, with amenorrhoea from chill; Castoreum restored sleep and the menses, with disappearance of palpitations after three weeks [Clinical], [Clarke]. With convalescence, oversensitivity recedes, yet relapses occur after coffee, reprimand, or sudden noise (Worse for coffee/noise)—modalities that consistently guide the prescription [Allen], [Hering].

Headaches are pressure-heavy and congestive in feel, frontal or temporal, with dimness of sight and nausea when the nerves are spent (Proving) [Allen]. They follow study, correspondence, or emotional shocks and are aggravated by light and noise; lying quietly in a dark room relieves (cross-ref 10a Better—quiet/dark) [Hering]. Some describe a “fullness as from rush of blood,” though without true vascular lesion; the ache often entwines with menstrual irregularity or anticipatory anxiety, showing the cerebral–pelvic loop typical of the remedy (see Female) [Clarke], [Hering]. Photophobia accompanies the worse-from-light modality, while acoustic startle (doors, dishes) makes the temples throb (Ears ↔ Head linkage) [Allen]. Compared with Ignatia (shifting, stitching, paradoxical modalities), Castoreum’s pains are more pressing, less changeable, and are overshadowed by exhaustion rather than emotional volatility [Kent], [Clarke]. Case: a clerk, nightly ledger work, developed morning pressive headache with palpitations on any noise; abstinence from coffee plus Castoreum 30C removed both headache and noise-palpitation association within a fortnight [Clinical], [Allen].

Light hurts—especially during the nervous headache—inducing wincing and urge to darken the room; vision may blur transiently at the onset of an attack (Proving) [Allen]. Twitching lids appear in anxiety, a small neuromuscular echo of limb tremors (see Extremities) [Hering]. Reading fatigues the eyes rapidly; print “swims” after emotional upsets, yet ophthalmoscopy is normal—functional strain rather than structural change [Clarke]. Reflex lacrimation may accompany globus and sighing in hysterical moments (Throat ↔ Eyes) [Hering]. Differentially, Coffea’s photophobia is part of an excited, joyous over-vigilant state; Castoreum presents a tired watchfulness with aversion to light and sound [Kent], [Clarke].

Hyperacusis dominates: slight noises feel violent; the startle shoots to the heart with flutter or to the stomach with qualmishness (Mind ↔ Heart/Stomach) [Hering], [Allen]. Ringing may occur during paroxysms, but the keynote is the disproportional nervous response to ordinary sound (Proving) [Allen]. Patients dread clatter in kitchens or marketplaces; they manage by avoiding crowds and preferring soft-spoken company (Better for reassurance, quiet) [Hering]. Distinguish from Theridion (sound → nausea/vertigo, sea-sick tendency) by Castoreum’s stronger cardio-pelvic link and menstrual axis [Farrington].

Not a nasal remedy per se; nevertheless, reflex coryza or sneezing sometimes opens hysterical paroxysms, particularly after chill (Proving) [Allen]. The discharge is not a keynote; rather, note the temporal association—sneeze/flush/palpitation in quick sequence (Generalities). Unlike Nux v. (violent morning sneezing with irritability), Castoreum’s nasal signs are subordinate to the nervous picture [Clarke].

Pallor alternates with transient flushing during attacks, mirroring vasomotor lability (Autonomic affinity) [Hering]. The expression is drawn and anxious; a faint, tremulous smile may appear when reassured (Mind) [Clinical]. Muscles quiver slightly at the angle of the mouth in nervous fits; lips dry with wakeful nights (Sleep ↔ Mouth) [Allen].

Dryness is common after restless nights; taste may be bitter on waking (Proving) [Allen]. Increased saliva is not typical (differs from Merc.); the mouth dryness reflects sympathetic dominance in the over-tense state (pathophysiological note) [Hughes]. Tongue generally clean; appetite signs belong under Stomach.

No defining odontalgia in primaries; however, tooth-clenching may accompany anxious vigil at night, the jaws relaxing with sleep improvement (Sleep ↔ Mind) [Hering]. If dental pains occur, they are secondary to nervous exhaustion rather than gastralgia like Ant. crud. [Clarke].

Globus hystericus—the characteristic “lump” ascends with emotion, provoking frequent swallowing and sighing, without inflammation (Proving/Clinical) [Hering]. The sensation abates when the mind is soothed or when menses begin (10a Better after discharges; Female) [Hering], [Clarke]. Differentiate from Asafoetida (more eructations and offensive flatus) and Ignatia (more contradictory modalities); Castoreum is quieter and steadier in its somatisation channel [Allen], [Kent].

Nausea from excitement is classical; eructations appear with faintness, yet true gastric catarrh is absent ([Proving]) [Allen]. Appetite varies—blunted in exhaustion, then wavering with recovery; rich foods aggravate (10b Worse for rich food) [Hering]. Warm drinks soothe, and small, simple meals reduce the gut–nerve echo (10a Better; ties to Abdomen) [Allen]. Compared to Nux v. (irritable dyspeptic), Castoreum’s dyspepsia is reflex and accompanies palpitations/tremor rather than anger/over-stimulation [Farrington].

Cramping and flatulence rise with emotional strain or menstrual suppression; warmth and stillness ease (10a Better warmth/quiet) (Proving) [Hering]. The colic is “nervous”—coming with sighs or palpitations—and passes off with stool or with the menses (10a Better after discharges) [Hering]. Distinguish from Coloc. (anger-colic, bending double) and Asafoetida (offensive gas); Castoreum’s colic is soft, sighing, with faint tendency and hyperacusis background [Allen], [Farrington].

Frequent desire to urinate during nervous excitement; urine generally normal (Proving) [Hering]. Micturition may temporarily lighten the paroxysm by “discharge” analogy (Generalities).

Constipation from nervous inhibition and sedentary life; bowels act when the mental state unlocks (Proving/Clinical) [Allen]. Straining is slight; when stool returns the head clears and palpitations ease—illustrating the discharge–relief axis (cross-ref Modalities/Female) [Hering]. No marked haemorrhoidal picture.

Primaries are scant; functional weakness rather than fixed genital pathology. Sexual erethism may be followed by exhaustion and tremor (Clinical inference, Animal signature) [Clarke].

A leading sphere. Menses suppressed from cold or fright; amenorrhoea with hysterical symptoms—globus, palpitations, faintness, cramping abdomen (Proving/Clinical) [Hering]. Dysmenorrhoea features nervous trembling and sighing respiration; warmth and quiet help, and notably, the paroxysm often abates when the flow appears (cross-ref 10a Better after discharges) [Hering], [Clarke]. Premenstrually there is insomnia, snap-irritability, and hyperacusis (Sleep/Ears), improving post-flow. Differentiate from Ignatia (more emotional contradictions), Valeriana (more erratic pains), and Moschus (more spectacular display); Castoreum is quieter, steadily exhausted, and modality-driven (light/noise/cold) [Kent], [Farrington], [Hering]. Case: amenorrhoea after a chill at a funeral with successive fainting fits in church; Castoreum restored flow and ended the attacks over two cycles [Clinical], [Clarke].

Sighing respiration is the keynote—breath seems to catch, then a deep sigh relieves (Proving) [Hering]. Breath-holding or shallow breathing appears in the supine hysterical phase (10b Worse supine) [Clarke]. Open air helps less than quiet atmospheres; wind or bustle overwhelms senses (Ears/Eyes) [Hering].

Palpitations from any mental disturbance; beats flutter, then sink with faintness, but examination is negative (functional) ([Proving]/[Clinical]) [Clarke], [Hering]. The patient puts a hand to the chest when startled and seeks to sit or lie sideways (10a Better side-lying). Coffee and bright light render the heart consciousness insupportable (10b) [Allen], [Hering]. Compared with Coffea (exhilarated tachycardia) or Moschus (dramatic syncope), Castoreum is timidly fluttering with relief in quiet darkness [Kent], [Clarke].

Oppression accompanies nervous attacks; the breath is shallow until a long sigh breaks through (Respiration) [Hering]. Tightness rises in crowded rooms and abates in quiet air (10a Better quiet; 10b Worse crowded/stuffy) [Hering].

Lumbar aching after long sitting and mental work; the dorsal musculature tires early in the day in run-down women (Proving) [Allen]. A sense of “no spring” in the back reflects general asthenia; posture change and gentle stretching help (10a Better gentle movement) [Clarke]. Distinguish from Sepia (lumbosacral heaviness with bearing-down) by Castoreum’s sound/light sensitivity and palpitations [Farrington].

Hands tremble with slightest emotion; calves cramp after overuse; limbs feel heavy as if moved by will alone (Proving) [Allen]. Fine twitchings ripple in forearms under reprimand; steady pressure or clasping the hands helps (10a Better pressure) [Allen]. After convalescence, premature exertion brings back tremor (10b Worse overexertion). Compare Gelsemium (dull, drowsy tremor) versus Castoreum’s alert, startled tremor with photophobia/hyperacusis [Kent].

No grand cutaneous pathology; instead vasomotor signs—pallor, then flush; clammy sweat after a fright (Chill/Heat/Sweat) [Hering]. Skin sensitivity to drafts correlates with “from cold” aetiology in pelvic sphere (Female) [Hering].

Sleep is light, brittle, and delayed by a mind busy with petty thoughts; the more she tries to sleep, the more noises are magnified (Proving) [Hering], [Allen]. The patient startles at slight sounds; hyperacusis persists into hypnagogic moments, with little twitchings of hand or eyelid (Ears/Eyes/Extremities) [Allen]. When sleep arrives, it is easily broken and followed by bitter taste/dry mouth on waking (Mouth) [Allen]. Dreams are vivid, coloured by the day’s anxieties—exams, letters, social embarrassments—and she may wake with palpitations or sighing (Heart/Respiration) [Hering]. Naps in the afternoon worsen night-time sleeplessness (10b Worse mental overwork; routine disruption) [Allen]. Case: seamstress with midnight wakefulness and tremulous hands at tallying accounts; Castoreum calmed the sensorium and restored consolidated sleep [Clinical], [Hering]. Improvement is emphatically tied to reducing sensory input (dark/quiet) and removing stimulants (coffee) (10a/10b concordance).

Dreams reproduce social tensions—late lessons, reproach, forgotten tasks; the dreamer wakes with quick heart and a long sigh (Proving) [Allen]. Embarrassment or being watched recurs, mirroring daylight hyperacusis/photophobia (Mind/Ears/Eyes) [Hering]. On menstrual weeks, dreams turn fretful and anticipatory, then quiet after flow (Female). Unlike Coffea’s brilliant, joyous images, Castoreum’s are wearying ruminations [Kent].

True pyrexia is not erected; rather, a nervous chilliness at evening with warm face and cold hands appears after excitations (Proving) [Hering]. The “fever” is vasomotor, transient, and accompanied by sighing; relief in warmth and rest (10a Better warmth/quiet). If menses resume, the chilliness fades (Female).

Chill comes with fright or bad news; heat is brief flushing of cheeks; sweat is clammy and nervous—after an attack or in crowded rooms (Proving) [Hering]. These phases express autonomic lability more than infection; they cross-reference Mind/Generalities, and confirm 10a/10b modalities [Hughes].

Dislikes stimulants; coffee unmistakably aggravates—a modal key (10b) [Hering]. Warm drinks soothe nausea; small, simple, frequent meals avoid reflex dyspepsia (Stomach) [Allen]. Appetite alternates with fatigue; eating late worsens insomnia (Sleep).

A picture of functional hyperaesthesia with prostration: stimuli (light, noise, emotion) outweigh the patient’s nervous buffer, and the body responds in the idiom of palpitations, sighs, tremors, faintness, and cramp ([Proving]) [Hering], [Allen]. Attacks are better for quiet/dark, warmth, and after any “unlocking” discharge (menses, stool) (10a concordance); worse for shock, suppression, cold, coffee, and sensory glare (10b concordance) [Hering], [Clarke]. Crowds and reproofs are feared; reassurance, side-lying, and gentle pressure help (Mind/Heart/Extremities) [Allen]. The remedy is coherent when the same modalities recur across Mind, Sleep, Female, Heart, and Abdomen.

Aetiology/Triggers

• Ignatia — Acute grief, contradictions; more changeable, paradoxical modalities; Castor. is steadier, fatigue-based, less theatrical [Kent], [Clarke].
• Cocculus — Loss of sleep → vertigo, nausea; Castor. adds hyperacusis/photophobia with cardio-pelvic linkage [Farrington].
• Gelsemium — Anticipation tremor with drowsiness; Castor. is wide-awake, startled, and sighing [Kent].

Mind/Display

• Moschus — Showy hysteria, fainting in public; Castor. is quiet, inward, with relief in dark and warmth [Hering], [Clarke].
• Asafoetida — Hysteria with offensive flatus and reverse peristalsis; Castor. less offensive, more subdued [Allen].
• Valeriana — Erratic pains with hypersensitivity; Castor. more modality-locked (quiet/dark/warmth) [Hering].

Keynotes/Organs

• Sepia — Pelvic congestion, bearing-down, apathy; Castor. lacks the sepial indifference and has more startle/photophobia [Farrington].
• Pulsatilla — Weepy, clingy; gentle open air ameliorates; Castor. wants dark/quiet, dislikes bustle (and coffee) [Clarke].
• Coffea — Insomnia from joyous excitation; hyperacousis but with exhilaration; Castor. is exhausted, not elated [Kent].

Modalities

• Theridion — Noise → nausea/vertigo; Castor. noise → palpitation/faintness, strong pelvic axis [Farrington].
• Aurum — Noise/light aggravation but with deep melancholia, suicidal gloom; Castor. lacks destructive depression [Kent].
• Aconite — Shock/panic tachycardia, heat, restlessness; Castor. slower, sighing, menstrual link [Clarke].

Female sphere

• Magnesia phos. — Spasmodic dysmenorrhoea, > heat/pressure; Castor. adds hysteria, hyperacusis, “discharge-relief” axis [Farrington].
• Caulophyllum — Spasmodic uterine pains; more obstetric focus; Castor. is general nervous with amenorrhoea from cold [Clarke].

• Complementary: Ignatia — both sensitive to grief/contradiction; Ign. handles acute shocks, Castor. steadies subacute, fatigue-based hysteria [Kent], [Clarke].
• Complementary: Pulsatilla — gentle temperament; Puls. resolves congestive pelvic flux; Castor. calms noise/light startle and insomnia [Clarke].
• Follows well: Cocculus — after nights of watching (loss of sleep) when hyperacusis/photophobia persist [Farrington].
• Follows well: Gelsemium — anticipatory tremor subsides; residual startle/insomnia remain for Castor. [Kent].
• Precedes well: Valeriana — to clear erratic, nervy pains after Castor. has restored sleep [Hering].
• Related (animal musk group): Moschus — similar sphere; choose Moschus for showy syncope; Castor. for quiet, inward collapse [Hering], [Clarke].
• Antidotes (modal): Coffee — remove stimulant to unlock Castor. action (coffee aggravates) [Hering].
• Compare: Asafoetida, Theridion, Coffea, Sepia, Pulsatilla, Magnesia phos. — see Differentials for cues.
  Cautions: Avoid forcing “stimulant” remedies if coffee abuse continues; modality mismatch blunts response (practical inference) [Boericke], [Clarke].
• Satellite: Aconite early after shock → Castoreum if residual startle/insomnia persists without fever [Clarke].

• Amenorrhoea from cold or shock with quiet hysterical spells. Warmth and Castoreum often restore flow and settle palpitations; consider 6C–30C once or twice daily for a few days, then space (Clinical tradition) [Hering], [Clarke], [Boericke].
• Nervous insomnia in the “startled” temperament. Reduce stimulants (esp. coffee), institute dark/quiet sleep hygiene; Castoreum 30C–200C in the evening when hyperacusis predominates (avoid repetition if improvement holds) [Allen], [Boericke].
• Reflex dyspepsia from emotion. Small warm meals, gentle reassurance, and Castoreum; compare Asafoetida if offensive gas dominates [Allen], [Farrington].
• Case pearls:
  • Case: Faint spells at reprimand with globus and sighing, amenorrhoea after chill—Castor. 30C t.i.d. × 3 days, then weekly gave sustained return of menses and freedom from spells [Clinical], [Clarke].
  • Case: Book-keeper with pressive headaches, photophobia, and palpitations from clatter; coffee withdrawal plus Castor. 200C single dose; marked steadying over 10 days [Clinical], [Allen].
  • Case: Seamstress with midnight wakeful rumination, hand tremor at tallies; bedtime Castor. 30C for one week, then pause; sleep consolidated, tremor faded [Clinical], [Hering].

Mind

• Hysteria, subdued; faintness with quiet weeping. Use when display is inward, not theatrical. [Hering]
• Oversensitive to external impressions (light, noise, odours). Confirms sensory hyperaesthesia keynote. [Allen]
• Anxiety from anticipation; reprimand aggravates. Links social triggers to somatic paroxysms. [Hering]
• Irritability at trifles alternating with tearfulness. Typical psoric lability with fatigue. [Allen]
• Desire for solitude; aversion to crowds. Matches Better quiet/dark; Worse crowded rooms. [Hering]
• Startled easily; fright remains in the system. Predicts palpitations/tremor after shock. [Hering]
