The essence of Cadmium sulphuratum is complete physical prostration with persistent vomiting and collapse, especially in malignant or destructive disease processes. The patient lies still, unable to move without renewed vomiting, yellow-faced, cold, and clammy, with a quiet despair and resignation.

Calc-carb. embodies the architecture of security—building, bearing, and maintaining the organism in the face of cold, damp, and demand. The constitution is heavy yet weak, plentiful yet poorly assimilated: a body that perspires, tires, enlarges glands, and worries, while bones lag and mucosae weep. Psychologically, it is the dutiful provider/child, conscientious, home-centred, averse to risk, who fears collapse—of health, sanity, finances, or structure [Kent], [Tyler]. This security drive seeks warmth, routine, rest, and predictability; it flounders in cold, damp, exertion, and sudden demand.

Kingdom signature (mineral salt) confers structure, boundaries, density, and stability; when impaired, we see laxity, sag, delays, enlargement (glands, abdomen), and suppuration. The metabolic idiom is sour: sour stool, sour vomit, sour sweat; the thermal idiom is chilly with head-sweat. Mind–body isomorphic motifs recur: fear of heights ↔ vertigo on ascending; fear of exertion ↔ palpitation/sweat climbing; need for security ↔ routine-seeking; structural laxity ↔ hernias, ptoses, prolapses. At the bedside, triangulate: (1) the constitution (flabby, chilly, sweaty, large abdomen), (2) organs (bones/teeth, glands/adenoids, catarrh/otitis), (3) mind (fears of collapse, conscientiousness), (4) modalities (worse cold, damp, exertion; better warmth, rest). When these resonate across two or more systems, Calc-carb. stands prominent. Cure appears as stamina to mount stairs, dry, warm feet, scalp no longer drenched, catarrh dwindles, child steadies in growth and confidence—the body’s architecture restored. [Hahnemann], [Hering], [Allen], [Clarke], [Kent], [Boericke], [Tyler], [Phatak], [Boger], [Nash].

Calcarea fluorica stands at the crossroads of hardness and laxity. Wherever the organism has lost elastic recoil yet produced stony compensation, this remedy speaks. The keynote triad is: (1) hard, glassy induration (exostoses, spurs, nodes, callosities, stony glands, fibroids); **(2) lax supports (varicose veins, prolapse, “weak ankles,” recurrent sprains); **(3) kinetic pattern of first-motion stiffness improving with continued motion, under a climate of worse cold/damp and better heat/support [Hering], [Boger], [Clarke], [Boericke]. The psychology mirrors this biomechanical story: practical, functional patients measuring progress in millimetres—how the heel feels on first step, how a node’s edge softens under warmth, how long they can stand before veins protest. This is not a remedy for incendiary inflammation or corrosive destruction (those belong to Fluor-ac., Sil., Hepar); it is a builder-and-binder, restoring tensile integrity to tissues that have become slack, while gently “resolving” excess hardening that bars motion.

It differentiates cleanly within the Calcarea triad: Calc-c. is soft, flabby, fearful; Calc-phos. grows and knits with ache; Calc-f. hardens where needed, softens where over-hardened, and re-elastifies fibrous planes. It allies to post-traumatic sequelae (spurs, rigid scars), developmental enamel defects, venous wall atony with knotty varices, pelvic and cervical rigidity with fibroid hardness, and the chronic “old sprain” that never fully recovered because the ligament remained lax while periosteum over-grew. Prescribing hinges on recognising the texture (stony versus spongy), the kinetics (start-up stiffness that eases), and the weather (cold/damp aggravation). When these axes align, Calcarea fluorica often unlocks durable change—less pain at first step, softer node margins, a cleaner tooth surface response, and fewer fissures tearing in winter—quiet, structural victories that mark the remedy’s essence [Hering], [Clarke], [Boericke], [Farrington], [Boger], [Phatak].

A restorative remedy for the delicate, rapidly growing, or constitutionally weak, especially when the lungs and nutrition are compromised. Bridges the gap between Calcarea phosphorica’s bone-building and Phosphorus’s lung affinity, acting as a direct nutrient stimulant in the debilitated. Night sweats, early chest weakness, and inability to gain weight despite fair appetite are keynote.

A remedy for the scrofulous and tubercular constitution, combining calcium’s nutritive, structural support with iodine’s gland-resolving power. Its essence is slow, chronic glandular enlargement with induration, particularly in children and adolescents, often with chronic catarrh and sluggish development.

A growth and nutrition remedy par excellence, Calcarea phosphorica addresses the delicate, anaemic, growing organism — the child with open fontanelles, the adolescent with growing pains, the young woman with delayed menses, the adult convalescent who cannot regain vitality. It bridges calcium’s structural building with phosphorus’s nervous energy, creating resilience in both bone and spirit.

Calcarea sulphurica is the finisher of suppuration. Wherever an abscess, pustule, sinus, or catarrhal cavity has opened and drains yellow, creamy matter, yet never quite finishes, Calc-s. helps organise the end-game—sustained drainage, tidy granulation, and steady closure. The essence is completion and cleanliness: Better for warmth, for free flow, for gentle cleansing, and Worse for cold air, damp, night, and premature sealing that traps pus and restarts throbbing. The picture is calmer than Hepar (less hypersensitive, less “splinter-like” pains), less expulsive than Sil. (not about driving out foreign bodies), and less reactive/inflammatory than Sulph. (less burning/itch, less offensive). It bridges the middle-to-late phase of repair across systems: in ENT (post-quinsy lingering exudates, otorrhoea), eyes (recurrent styes/chalazia), chest (chronic yellow expectoration), skin (acne, boils, carbuncles), pelvis (Bartholin abscess, bland yellow leucorrhoea), and dentistry (post-alveolar ooze).

Miasmatically it blends psora (chronicity, sluggish healing) with sycosis (proliferative tracts, pus pockets) and, where ulceration becomes destructive, a syphilitic hue—yet its clinical aim remains constructive: consolidate granulation and close. The patient’s temperament is workmanlike, bothered chiefly by the unfinished state and the nuisance of constant cleansing. The guiding polarities—Warmth vs cold/damp, flow vs suppression, even conditions vs draughts, night aggravation vs morning relief—must be explicit in the case. When present, Calc-s. quietly turns the corner from lingering discharge to definitive repair, often in concert with surgical hygiene and prudent local care [Hering], [Clarke], [Boericke], [Boger], [Phatak], [Kent].

A slow, cold, indurating remedy for chronic degenerative states, especially in debilitated, cachectic constitutions. It addresses glandular hardness, foetid discharges, and venous stagnation. The patient is mentally and physically sluggish, with a deep-seated loss of vitality, often after long illness, grief, or toxic exposure.

Carbo vegetabilis is the reviver of vital force—a remedy for when the system has nearly ceased to function, yet some spark remains. It represents the person who is cold, ashen, flatulent, and faint, overwhelmed by internal stagnation. Whether from loss of fluids, shock, or chronic debility, Carbo vegetabilis restores through the vital breath—oxygen, air, and circulation. When the patient gasps for air, craves to be fanned, and cannot digest even a morsel, Carbo vegetabilis brings light into the shadows.

A profoundly septic, destructive, low-reactive remedy for states of collapse and putridity. It is suited where the organism seems overwhelmed by toxic influence, with offensive discharges, rapid tissue breakdown, and paralysis of both mind and body. The keynote is sudden prostration with foetid emanations and sloughing ulceration.

Carboneum sulphuratum is the picture of slowly advancing neurodegeneration—a creeping paralysis of body and mind from toxic insult. The patient gradually loses coordination, vision, hearing, and memory, while sinking into apathetic weakness. It suits long-term industrial toxin exposure, chronic neuritis, and optic atrophy with spinal symptoms.

Causticum centres on a dual failure of innervation: flaccid paresis of control (sphincters, larynx, facial and ocular muscles) coexists with contracture of flexors and tendons. The organism cannot hold (urine, stool, voice, eyelid) yet cannot let go (tight hamstrings, torticollis, writer’s cramp). Over this neuro-trophic ground lies a cutaneous–mucosal rawness: the patient is rubbed sore by the world—throat scraped, chest raw, anus and vulva fissured, skin cracked, warts sprouting on hands and face. The air must be moist: dry cold wind steals the voice, contracts the sinews, and freezes the tears; damp rainy weather soothes the larynx and softens the spasms.

Psychologically, Causticum is a fighter for the wronged. The child who cries when he hears a sad story, the mother who lies awake until her son returns, the teacher whose voice fails when speaking out, the man who develops facial palsy after standing in a keen east wind while protesting a wrong—these draw the portrait. Justice and loyalty are spinal; suppressed indignation and vigil for others drain the nerve battery. Thus emotion is a causation equal to exposure: grief for others, fear something will happen, anger at injustice—each may precede aphonia, ptosis, urinary dribbling, or writer’s cramp. The modality structure clinches: worse dry cold, drafts, morning, long talking, first motion; better damp weather, warmth, gentle continued use, rubbing, warm drinks.

Clinically, choose Causticum when paresis and contracture coexist; when laryngeal loss of power sits with urinary incontinence; when facial or ocular palsy follows exposure; when warts/fissures accompany a raw mucosal theme; when the conscientious, sympathetic temperament looms large. It stands midway between Gelsemium (soft, flaccid, timid) and Plumbum (hard, retracted, destructive), with a humanitarian heart that is unmistakable at the bedside. [Hahnemann], [Hering], [Kent], [Clarke], [Boger], [Boericke], [Farrington], [Tyler], [Phatak], [Nash]

Chininum arsenicosum stands where time and decay meet: the intermittent clock of Cinchona with the burning prostration of Arsenicum. The patient is pale, tremulous, breathless, tied to fixed hours: chill at four, heat at six, sweat at eight—each stage draining a little more vitality. In the background lie spleen and portal congestion, a tired heart, a scant kidney, and a mind that keeps watch on the minute-hand. He is worse at night, worse from cold air/drinks, worse from the least effort; better with warmth, small frequent sips, quiet, and propped rest, and relieved when sweat completes the sequence. This coherence of modalities is not decorative—it is the clinical lever: arrange the patient’s day by warmth, small feedings, and rest, and the remedy has purchase. [Clarke], [Boericke], [Nash]

The organ signature is a triangle: spleen (post-malarial residue), heart (palpitation, asthma of weakness), kidney (albuminuria/oedema). Neuralgias belong to the same cycle—periodic, burning, exhausting—answering to warmth and quiet. Compared with China, Chin-ars. is deeper, more cachectic, and more cardio-renal; compared with Arsenicum, it is more clock-bound, less pan-obsessive, and more likely to sweat out the paroxysm with relief. Against Cedron’s chronometer neuralgia and Chin. sulph.’s ear-led periodicity, Chin-ars. is the systemic antiperiodic for the feeble: the remedy that breaks relapse while propping the patient. Cure looks ordinary yet decisive: the hour drifts, paroxysms grow short and mild, breath returns on stairs, oedema recedes, sleep comes without dread, and strength rises to meet the day. [Farrington], [Clarke], [Boericke]

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]

Cholesterinum is the stone-and-bile remedy: right hypochondrial colic to right scapula, clay stools, dark urine, bitter mouth, nausea, and bilious headaches that abate with bile flow. Its modalities circle the kitchen and the belt: fats, alcohol, odours, and tight clothing bring trouble; heat, pressure, stillness, small warm sips, and a brown stool bring peace. The terrain shows xanthelasma, sallow skin, intolerance of rich foods, and portal sluggishness. Unlike Chelidonium (perpetual scapular stitch) or Chionanthus (nausea-centric acholia), Cholesterinum speaks when lithiasis and acholic evidence anchor the case. A good outcome looks ordinary but decisive: the stool browns, urine lightens, headache and itch cease, scapular pain vanishes, and—under a simple diet—colic does not return. Historical reports extended its use to fatty change and hepatic growths; these are part of the materia medica tradition and must sit alongside appropriate medical care. [Burnett], [Clarke], [Boericke], [Allen], [Farrington]

At its core, Chromicum acidum expresses destructive, septic toxicity with sudden, periodic attacks in a cold, exhausted organism. The central image is that of a powerful corrosive and antiseptic acid turned inward, attacking the very mucous surfaces it was once used to “cleanse” – nose, throat, uterus, bowel – and provoking haemorrhage, ulceration and gangrenous tendencies. The patient experiences life in waves: abrupt onsets of pain, diarrhoea, haemorrhage or angina that seem to come from nowhere, then recede, only to reappear at characteristic hours, especially in the early morning.

The organism is cold and fragile. A slight draught aggravates pains; cold water sets off neuralgia or toothache; the head feels heavy yet empty, the heart feels like a vacuum and the chest like a hollow cavity. Despite this emptiness, there is internal congestion: fulness in head, throbbing from heart to left eye, pressures in chest and abdomen. The circulation is unstable: the pulse may sink to extraordinary slowness before dawn, then quicken later, or jump with each diarrhoeal or haemorrhagic episode. This rhythm of collapse and resurgence reflects the acid-group tendency to debility accompanying diarrhoea and haemorrhage.

Psychologically, the patient is often clouded, confused, their memory failing them for simple things like letters of the alphabet. They feel as though intoxicated or narcotised, moving through a fog in which sudden internal events – stabbing heart pains, violent toothache, abrupt colic – erupt without warning. Dreams of poisoning, of unjust execution, of freezing water turning to ice, reinforce the sense that the world (and their own body) is hostile and treacherous. Yet the mental disturbance is rarely the primary layer; it is more a faithful echo of the toxic, haemorrhagic, septic processes taking place in the tissues.

Organ-wise, three axes define the remedy: nose/throat, gut/rectum and heart/back. Fetid, musty smell in posterior nares, ozena, ulceration and tough, adherent mucus in throat and post-nasal space show the local destructive action on mucosa. The gut axis manifests as early-morning abdominal crises with watery diarrhoea, nausea and vertigo, alternating with constipation, fulness and haemorrhoids. The heart/back axis includes angina-like pains, vacuum sensation at heart, great variability of pulse, and lumbago or small-of-back weakness – often directly related to haemorrhoidal or uterine haemorrhage.

Miasmatically, Chr-ac. lies in the syphilitic realm of destruction and ulceration, with sycotic overtones in warts and post-nasal tumours, and a psoric functional weakness in digestion and rheumatism. It is not a grand constitutional archetype but a remedy for specific states of corrosive and septic breakdown, particularly when local discharges are suppressed or mishandled. The history may include: industrial exposure to chromic acid or similar caustics; surgical or chemical suppression of warts or ulcerations; excessive use of antiseptic washes; or repeated violent episodes of gastritis, haemorrhoids or uterine bleeding.

In differentiation, one might say: Kali-bich. shares stringy mucus and sinus involvement but lacks the pronounced watery diarrhoea and cardiac variability; Merc-cor. is more constantly tenesmic and dysenteric; Ars. more anxious, burning and restless; Nit-ac. more fissured, splinter-like and deeply syphilitic in general. Chr-ac. stands out when offensive discharges, watery diarrhoea with vertigo, haemorrhoids, foetid lochia, vacuous heart sensations and shifting rheumatism occur together, with a marked periodicity and sensitivity to cold or draughts.

In this wider reading, one may see Chr-ac. as a remedy of systemic instability: vascular tone, mucous integrity and even metabolic resilience can fail suddenly in the early morning. Thus in diabetic patients who are cold, exhausted, prone to abrupt diarrhoeal or haemorrhoidal crises, with foul odours from nose or lochia and angina-like sensations, Chr-ac. may act as a constitutional remedy addressing the deeper destructive terrain rather than merely a sugar remedy.

Cinnabaris stands where Mercury’s destructive edge meets Sulphur’s inflammatory mucosa—a syco-syphilitic signature expressed in mucous overgrowths (polypi, condylomata) and ulceration/Periosteal pains that announce the night. The essence is the blocked passage: a posterior “lump” at the choanæ that compels hawking, a bridge-of-nose pressure that narrows one’s world to a bar across the face, and a caruncle that feels lumpy and angry; once the plug loosens and air is taken in the open, the mood and mind unshackle (Essence ↔ Nose/Throat/Eyes; Modalities). This inner obstruction radiates to sex and self-image: lasciviousness surges at night, condylomata and mucous patches shame the patient, and fetid odour from ozaena or mouth undercuts confidence (Mind/Female/Male). The polarity is closed–open: close rooms, damp, warmth to head, suppression of discharge, sexual excess close the system and worsen; open air, free discharge, loose clothing, and lukewarm sips open it again (10a/10b).

Pathophysiologically, mercurial influence explains night-bone pains, stomatitis, offensive secretions, and a tendency to sweat without relief; sulphide’s mucosal affinity expresses as tenacious green/yellow mucus, posterior “string”, caruncle swellings, and polypi (Affinity). The miasmatic weave is clear: sycotic overgrowth (warts/polypi) rides with syphilitic ulceration (ozaena, coppery eruptions, periosteal pains), while psora maintains the chronic catarrh and reactive skin (Miasm). The pace is chronic–recurrent, with flare-ups in damp warmth and after suppression; it seldom races like Merc. cor., but erodes steadily unless vent is restored (Differentials). The psychological portrait is practical, sensual, self-conscious: less tragic than Aurum, less weepy than Pulsatilla, less generalised than Merc. sol.; the mind frets about odour, appearance, and blocked passages, then eases once air and discharge flow. In Scholten’s terms the Mercury series wrestles with performance/communication; here the message is literally stuck in the passage until Sulphur’s outward drive re-opens it. Cure reads in simple but decisive signs: the bridge no longer aches, caruncle quiets, hawking ceases, polypi shrink, ulcers heal from within, bone pains stop waking him at night, and shame subsides as breath sweetens and the face is clear. [Hering], [Hughes], [Kent], [Clarke], [Phatak], [Boger], [Tyler]

Cobaltum metallicum binds three strands into one rope: (1) posture, (2) sex, and (3) study. The posture strand is the plainest: sitting is the enemy; walking the friend. The small of the back feels as if it would break when sitting, extending to coccyx and down a sciatic line; hard seats, long rides, and desk hours are the chief offenders (this tallies precisely with the modality already noted) [Hering], [Allen], [Boericke]. The sex strand ties in by a simple economy: sexual excitement and losses over-tax the cord; the next morning the back aches, mind frets, prostatic threads appear, and study is spoiled; a chaste night and a brisk walk restore tone. This is neither the crushed apathy of Phosphoric acid nor the moral laceration of Staphisagria; it is an erethistic state—touched off, spent, and then irritably regretful—with pains anchored in the lumbosacral span. The study strand expresses as occipital tightness and desk headaches that ease in open air, plus a mental distaste for the desk forged by the association chair = pain. The skin signs (acne in the sexually excited adolescent) and urinary tail (prostatorrhœa, urethral tingling) are satellites that confirm the line of force.

Miasmatically, the picture sits chiefly in sycosis—excess, congestion, catarrh of orifices, warts/acne—with a psoric functional weakness (no deep tissue ruin) and only a faint syphilitic tint in obstinate coccygeal pain [Kent], [Phatak]. Kingdom-wise, within the metals, Cobalt’s theme is tonus and use: over-use in one position (sitting) breaks tone; right use (movement/air) restores it. The remedy’s polarities are pragmatic: stillness vs. motion, indulgence vs. abstinence, close room vs. open air. Practical cure is delightfully ordinary: frequent breaks, exercise, temperance—and the medicine—yield mornings without emissions, even desk sessions, and backs that no longer cry at chairs. If, despite these, the case drifts into weak dribbling and exhaustion, Selenium or Phosphoric acid take the relay; if stitching, 3 a.m. back weakness persists, Kali carbonicum may close. But when the case reads like a ledger of sitting-hours, sexual over-touch, and occipital band, Cobaltum is the signature. [Hering], [Allen], [Clarke], [Boericke], [Boger], [Nash]

Cuprum aceticum condenses the copper story into a gastric–laryngeal–muscular storm: spasm in waves, collapse between. Copper’s neuromuscular irritability tightens flexors, locks thumbs, and narrows the throat; the acetate radical savages the stomach, adding violent retching and choleraic stools. The vagus nerve is the stagehand that pulls both scenes together: a cramp in the epigastrium tugs a thread upward to the larynx, and cough-fits tug it back to the stomach—paroxysms of retch-cough, cough-retch, culminating in cyanosis and clammy sweat [Hering], [Farrington], [Clarke]. The patient’s polarities are stark: hypersensitive to motion, touch, contradiction—yet flattened and apathetic after a fit; blue-cold surface with inner heat at the pit; wanting cold air on the face while the body shivers; desiring small cold sips though general chill predominates. Modality coherence is the clinician’s compass: better firm pressure and grasping (calves, abdomen, sternum), better doubling with colic, better small cold sips and cold to face/head during the storm; worse at night, in warm rooms, from emotions, from suppression (eruption or menses), and from the least jar [Kent], [Boger], [Clarke].
Miasmatically, the syphilitic colouring appears in the destructive, cyanotic, convulsive bias and in the danger of asphyxia; the sycotic thread shows in recurrent spasms and consequences of suppression; psora lends functional over-reactivity. Scholten’s mineral perspective sees “copper = control”: when control snaps, chaos bursts forth as spasm; Cupr. ac. adds acid’s corrosive push to precipitate the crisis [Scholten]. Vithoulkas notes the copper group’s child focus and nervous lability, which here magnifies into life-threatening paroxysms in infants and children (laryngismus, whoop) and choleraic adults [Vithoulkas]. Therapeutically, the essence is anti-spasm with anti-collapse: unlock the cramp and steady the circulation. Practical measures mirror the remedy: loosen clothing, admit cool air to the face, apply firm pressure to cramped muscles, allow small cold sips, enforce quiet. Micro-comparisons sharpen selection: Veratrum is icier, sweatier, more purgative; Arsenicum craves heat and is more mentally restless; Drosera coughs more and spasms less cyanotically; Mag-phos loves heat for cramp, while Cupr. ac. loves pressure and cold to the head; Cuprum metallicum is copper without the acetate’s violent gastric storm [Farrington], [Kent], [Clarke].

Copper + Arsenic = Spasm + Collapse under a Warmth-and-Small-Sips Law. Cuprum arsenicosum marries the neuromuscular discharge of copper—cramps, clenched thumbs, laryngeal clamp—with the burning–anxious prostration of arsenic—fear of death, small frequent sips (warm), cold sweat, cyanosis, and nocturnal aggravation. The clinical picture is a paroxysm–lull rhythm: violent retch–stool waves with calf/hand cramps; or whoop with crowing inspiration, blue lips, clenched thumbs; or anginal constriction with cold sweat and terror—each crest followed by a trough of exhaustion. The guiding polarity is thermal and behavioural: desires warmth (externally and internally) and small warm sips, pressure, bending double, quiet, and sitting propped; yet stuffy hot rooms and odours ignite air hunger and cough. This split—local cool fresh air to face, general body warmth—unlocks laryngismus without chilling the patient. The vagus axis is conspicuous: epigastric cramp tugs upward to throat (cough/stridor), downward to bowel (rice-water stool). As paroxysms recede under these exact modalities, anxiety falls in step, a sign that mind and soma are being treated together.

Miasmatically, the syphilitic shadow lends cyanosis, asphyxial danger, and erosive gastro-enteric states; sycotic recurrence accounts for patterned night attacks and relapse after suppression; psoric reactivity fuels hypersensitive starts and small-sips thirst. Compared with relatives: Cuprum aceticum is copper plus acetate—wants cold sips/air; Cuprum arsenicosum wants warm sips and general warmth (Arsenicum law). Veratrum is icier, sweatier, more purgative, less anxious-restless; Arsenicum album is warmer and more restless but less cramp-convulsive; Drosera whoops hard but lacks the blue-cold-collapse and widespread cramp; Mag-phos loves heat for cramp but lacks cyanosis and arsenical dread. The practitioner’s task is to enforce the remedy’s law in management: small, warm, frequent liquids; firm pressure/binding of cramps; absolute quiet; fresh air to face; warmth to body; avoid suppression; and dose appropriately. When these are observed, Cupr. ars. often converts a terrifying night of paroxysms into a sequence of shorter, weaker waves that finally break on the shore of sleep.

Essence: Explosive spasmodic remedy. Think Cuprum metallicum when a case is organised by spasm—cramps (calves/soles/hands/gut), convulsions with blue face and thumbs clenched, laryngeal/chest constriction, whoop with rigidity and cyanosis, or cholera with vomit–cramp alternation—especially after suppression (eruption, perspiration, menses/lochia) or suppressed emotion (fright, vexation). Auras climb from legs/knees upward; hard pressure/rubbing, cold water in sips, cool air, and return of discharges relieve; night, touch of larynx, damp cold after heat, and suppression provoke. Use Cuprum to unlock the spasm, restore outlets, and avert collapse [Hering], [Allen], [Clarke], [Boericke], [Boger], [Nash], [Tyler], [Farrington].
