• Cerebral cortex & sensorium. Alters apperception: time dilates or stops; space vast or near; self feels double or dissolved—central keynotes. See Mind/Generalities. [Clarke], [Hale], [Boericke].
• Special senses (especially vision). Kaleidoscopic colours, star-bursts, mandala-like forms, intensified light, coloured halos; mydriasis. See Eyes. [Clarke], [Boericke].
• Sleep centres. Insomnia with persistent inner imagery; dreamy dozing without rest. See Sleep. [Boericke], [Hale].
• Autonomic / heart. Palpitation, irregularity, anxious heart-awareness; secondary to sensorium changes. See Heart/Chest. [Clarke], [Boger].
• Pain-perception. Relative analgesia or indifference to pain; serenity despite complaints. See Generalities/Mind. [Hale], [Clarke].
• Psycho-sensory integration. Synaesthesia: sounds perceived as colours, forms “sing”; hyperesthesias with paradoxical calm. See Mind/Eyes/Ears. [Clarke], [Boericke].

• Quiet, dim light, eyes closed—visions are beautiful and non-threatening; anxiety subsides. See Mind/Eyes. [Clarke].
• Music (soft)—harmonises imagery; synaesthesia becomes pleasant rather than disorienting. See Ears/Mind. [Hale], [Clarke].
• Aloneness and repose, contemplation; gentle reclining with eyes covered. See Mind/Sleep. [Boericke].
• Warmth and steady ambience; avoidance of startling stimuli. See Generalities. [Clarke].
• Steady, slow breathing; simple grounding reduces palpitation. See Heart/Respiration. [Boger].

• Bright light, glare, colours in motion—visions intensify to confusion. See Eyes. [Clarke], [Boericke].
• Noise, sudden touch, contradictions—startle amplifies percept distortion. See Mind. [Hale], [Clarke].
• Night, when trying to sleep—inner panorama prevents sleep. See Sleep. [Boericke].
• Longevity of effects after slight dose—long after-sensations; exhaustion after vigil. See Generalities. [Hale].
• Attempting exact tasks (reading fine print, measuring distance)—misjudgment provokes anxiety. See Mind/Eyes. [Clarke].

A leading sphere. Consciousness is expanded, split, or displaced: the patient may watch himself from outside, “two selves”, or feel ego-dissolution with serene impersonality—“nothing matters”—yet without the terror of Stram.; rather a tranquil wonder often prevails [Clarke], [Hale]. Time appears endless or arrested; minutes stretch to hours; space seems boundless or distorted (near seems far, small vast), causing missteps or misreaches [Clarke], [Boericke]. Synaesthesia: sounds paint colours; forms hum; aromas have “hues”—a signature crossover [Hale]. Imagination luxuriant, visions in splendid colours, mandala-like geometries, processional images, sometimes with religio-mystic exaltation; yet the will is quiet, not frantic as in Bell. [Clarke], [Boericke]. Indifference to pain and to bodily states appears; the sufferer may observe his discomfort as if another’s [Hale]. Anxiety, when present, arises from loss of orientation or heart-awareness; it is better by quiet, dimness, and reassurance [Clarke]. Memory for practical sequences is poor during the state; speech may become slow, rapt, or overly aesthetic; task-execution falters owing to time/space error [Clarke], [Boger]. Case note (Proving): “Felt lifted from body, gazed at self in bed; colours wheeled behind eyelids; no wish to sleep” [Hale].

Lightness as if head were hollow or floating; sometimes tight band-likeness with shimmering aura before eyes [Clarke]. Vertex expansion or skull feels open to the sky; turning the head misjudges distance, causing a sway [Boericke]. Dull aching after long vision-trance, better quiet and dark. Motion can provoke sea-like undulation in the brain; nausea is uncommon but may come from visual overload more than gastric disturbance (cf. Tab.) [Clarke].

Pupils dilated; light dazzles. With lids closed: intense kaleidoscopic colour-forms, star-bursts, spirals, mosaics; with lids open: haloed lights, coloured fringes, faces idealised or distorted (exaltation or grotesquerie) [Clarke], [Boericke]. Distance and size misjudged: the near recedes, the small enlarges. After-images persistent; phosphenes on pressure. Reading fails from dancing letters; better shaded room, worse glare [Clarke].

Music exquisitely vivid; tones appear coloured; echoes prolonged; ordinary noise jars and “splinters the colours” (patient’s metaphor) [Hale], [Clarke]. Tinnitus like silver bells or humming; hearing otherwise acute yet fatigued by disharmony.

Not a primary seat. Occasional phantosmia—scents perceived as hues (synaesthesia); nasal mucosa otherwise quiet. If coryza or rawness dominates, select another remedy [Clarke].

Quiet, rapt expression; pallor during intense inner panorama; flush with sudden emotion. Features may appear to the patient idealised (beautified) or mask-like in others—perceptual, not structural [Clarke].

Dryness moderate; taste altered to a subtle sweetness during ecstasy; thirst small despite wakeful nights (contrast Coff.) [Boericke]. Tongue may feel larger (kinaesthetic distortion).

No distinct odontalgic keynote; relative analgesia may mask minor dental pains during episodes [Hale].

Sense of wideness or unimpeded column in pharynx; swallowing automatic; little true soreness. Talking can feel effortful because time to form words seems long [Clarke].

Appetite indifferent; nausea rare, more from visual oscillation than gastric cause; eructations when anxiety touches the heart. Warm drinks ground the patient; stimulants aggravate perceptual flutter (differential with Coff.) [Boericke], [Clarke].

Unremarkable. Subtle abdominal “emptiness” during dissociation may be noted; bowels tardy after sleepless nights; nothing characteristic.

Slight polyuria after long vigil; otherwise negative.

No keynote beyond quiet bowel; if rectal symptoms predominate, search elsewhere.

Libido variably exalted or indifferent; sensations aesthetic rather than urgent. Erections weak during vigil; not a sexual remedy per se [Clarke].

States of mystic exaltation round menses have been noted, with insomnia and colour-visions; not a core gynaecic remedy.

Calm, slow; may become consciously regulated (patient watches his breathing clock). Dyspnoea is uncommon and psychogenic when present; reassure and darken room [Clarke].

Palpitation or irregularity from emotional or perceptual surge; the awareness of heart-beat may be magnified subjectively (time dilation); objective disturbance slight. Better quiet, recumbency, and slow breathing [Clarke], [Boger].

Chest feels wide; breath deep yet effortless; sighing in contemplation [Clarke]. Dryness or tickle minimal.

Lightness along spine; levitation sensations as if the dorsal region rose from the couch; no structural pain.

Limbs light, floating; movements mis-timed; reaches miss by inches (space-error). Analgesia or indifference to minor bruises; gait may be slow, ceremonial [Hale], [Clarke].

Touch exquisitely pleasant or neutral; pain-threshold raised. Colours seen “within” the skin with eyes shut—subjective phosphenes. Sweating slight, not relieving insomnia [Clarke].

A chief sphere. Sleepless because inner visions stream on; the patient lies tranquil, not restless, watching colours and processions; time ceases; on dozing, dreams continue the pageant; waking is unrefreshed though not miserable [Boericke], [Clarke]. Attempts to sleep worse in bright rooms; better in dark, quiet, cool ambience. Startle on crossing into sleep with sensation of falling then floating. After long vigil, daytime drowsiness without ability to nap (images return on closing eyes).

Brilliant, symbolic, geometric, ritual; sacred or ceremonial motifs; flying, floating, vast spaces, temples of light; often pleasant and observed rather than suffered; occasional anxiety when distance-time distort beyond control [Clarke], [Hale].

No febrile pattern proper. Heat or flush during vision-trance; chill if suddenly exposed to glare or noise; sweat slight.

Chill: from shock of light/noise. Heat: head/face during exaltation. Sweat: minimal, not relieving sensorium.

Little craving; alcohol, coffee may over-stimulate and confuse images (practical caution). Prefers cool water in sips.

The essence is altered apperception: brilliant inner colour-forms; time and space dislocated; ego loosened or doubled; serenity with analgesia. The state is quiet, contemplative, aesthetic—not the noisy terror of Stram. nor the irritable drive of Nux. Modalities are coherent: worse light, noise, effort, night (when trying to sleep); better dark, quiet, music (harmonious), repose. Indications arise in insomnia with racing inner imagery; post-shock derealisation; states of detached calm with poor tasking; heart-awareness with time dilation. Compare Cannabis-ind. (expansion of ideas/time, but more talkative/humorous), Bell. (florid delirium with heat and violence), Stram. (night-terror, terror of darkness), Op. (profound insensibility with retained images), Nux-m. (drowsy dissociation with dryness), Agar. (fantastic visions with clumsiness, more spinal twitch) [Clarke], [Boericke], [Boger], [Hale].

Expansion / Time–Space distortion

• Cannabis indica — Exalted ideas, laughter, music ravishment; more talkative and whimsical; Anh. is quieter, contemplative, colour-kaleidoscopic [Clarke], [Boericke].
• Nux moschata — Drowsy, dreamy, dry, memory blank; less colour-pageant; more sopor/forgetfulness [Boger], [Boericke].
• Opium — Grandiose visions with insensibility; heavy stupor; Anh. maintains clarity and aesthetics [Clarke].

Night terrors / ecstatic vs. fearful

• Stramonium — Terror, violence, hallucinations frightful; hates dark; Anh. welcomes dimness, serenity predominates [Clarke].
• Belladonna — Hot, throbbing, furious delirium; images vivid but pyrexial and aggressive; Anh. is afebrile, tranquil [Boericke].
• Hyoscyamus — Lewd, silly, jealous; hallucinations coarse; Anh. is artistic, mystical [Clarke].

Synaesthesia / aesthetic exaltation

• Agaricus — Fantastic dancing images with twitching, clownishness; Anh. is stately, mandala-like [Boger].
• Platina — Magnified self, aesthetic hauteur; less sensory crossover; more pride than poise [Clarke].
• Coffea — Hyperaesthesia, sleepless from ideas; but coffee aggravates; Anh. seeks quiet rather than mental jubilee [Boericke].

Analgesia / indifference to pain

• Opium — Painlessness with stupor; Anh. painless yet lucid [Clarke].
• Coca — Indifference with stimulation; motor over-activity; Anh. is inward, still [Boger].

Cardio-neurotic awareness

• Acon. — Acute fear-of-death, tachycardia from shock; Anh. has curious heart-awareness without panic [Clarke].
• Gelsemium — Dull, heavy, timid with tremor; no brilliant inner pageant [Boericke].

• Complementary: Cannabis-ind. (creative mind states; when talkative hilarity overlays Anh. serenity, Cannabis may complete the case) [Clarke].
• Complementary: Agaricus (when visual fantasia coexists with motor twitch/clumsiness) [Boger].
• Follows well: Acon. or Ign. after shock when derealisation persists as colour-visions with insomnia [Clarke], [Boericke].
• Precedes well: Coffea in purely ideational insomnia once the colour-pageant has subsided; or Nux-m. when the case collapses into drowsy dreaminess with dryness [Boericke], [Boger].
• Antidotes (clinical): Nux-v., Camph., quiet dark room, reassurance—when over-stimulated or anxious from perceptual overload [Clarke], [Boericke].
• Inimicals: None clearly recorded.

• Use-cases. Sleepless visions at night with serene detachment; post-shock derealisation with aesthetic inner scenes; creative over-aesthetic states impairing function; heart-awareness with time dilation but without frank panic [Clarke], [Hale], [Boericke].
• Potency & repetition. For functional insomnia and sensorium states: 30C once–twice daily for several days, then pause and watch. In entrenched perceptual syndromes: 200C single dose at night; repeat by clear relapse. Low potencies (6C/12C) if sensitivity high, with strict environmental supports (dark, quiet). Always reduce frequency as improvement holds [Boericke], [Boger].
• Adjuncts. Dark room, minimal screens, soft music if it soothes (otherwise silence), breathing cadence (4–6/min), warm non-stimulating drinks. Avoid late coffee/alcohol (tend to scatter imagery) [Clarke], [Boericke].
• Pearls.
  • “Dual consciousness” with beautiful colours and sleepless serenity → Anh. over Cannabis (more mirth, talk) [Clarke].
  • Synaesthesia (sounds as colours) is a fine pointer when insomnia is pleasant but ruinous to rest [Hale].
  • If the pageant turns fearful or violent, re-evaluate for Stram./Bell. shift.

Mind

• Dual consciousness; feels outside the body observing self. Keynote of Anh. [Clarke], [Hale].
• Delusions of time and space; minutes seem hours; distances misjudged. [Clarke], [Boericke].
• Exaltation; mystical serenity; indifference to pain. [Hale], [Clarke].
• Synaesthesia: hears colours / sees sounds. [Clarke], [Hale].
• Desire for solitude; aversion to interruption. [Boericke].

Head

• Head feels light, hollow, floating; vertex expansion. Better dark, quiet. [Clarke], [Boericke].
• Brain-waves as if undulating; motion aggravates visual nausea. [Clarke].

Eyes

• Mydriasis; light dazzles; coloured halos. [Boericke], [Clarke].
• Closed-eye kaleidoscopic visions (mandalas, star-bursts). [Clarke].
• Objects change size/distance (micropsia/macropsia). [Clarke].

Ears

• Music ravishing, appears coloured; echoes prolonged. [Hale], [Clarke].
• Noise intolerable; startles and scatters images. [Clarke].

Sleep

• Sleepless from inner visions; lies tranquil, watching colours. [Boericke], [Clarke].
• Dreams brilliant, symbolic; flying, temples, vast spaces. [Clarke], [Hale].

Heart / Generalities

• Palpitation with heightened awareness; anxiety better quiet/dark. [Clarke], [Boger].
• Analgesia / indifference to pain during exalted state. [Hale].
• Worse light, noise, night (on trying to sleep); better quiet, darkness, music. [Boericke], [Clarke].
