Heloderma

Heloderma is prepared from the venom/saliva of the Gila monster, a venomous North American lizard. Physiologically the crude poison in animals depresses temperature and circulation, produces marked numbness and muscular weakness, and may provoke staggering and ataxic gait—key effects later echoed in the homœopathic picture [Hughes], [Clarke]. The venom was triturated in the usual centesimal manner to produce the provings and clinical potencies [Clarke], [Boericke]. Toxicologic observations emphasise intense subjective and objective coldness (“as if ice in the veins”), peripheral cyanosis and torpor, with dryness of mucous membranes and obstinate constipation, all of which frame the therapeutic sphere in nervous and vaso-motor disorders (Raynaud’s, chilblains, frost-bite sequelae, arteriosclerosis, threatened apoplexy) and certain forms of angina and cardiac weakness [Allen], [Boericke], [Boger], [Clarke].

The pathogenesis arises from small volunteer provings collated with toxicology and clinical confirmations rather than a Hahnemannian large-scale proving; T. F. Allen and Hering compiled the chief effects, with Clarke furnishing clinical verifications in vascular-nervous conditions [Allen], [Hering], [Clarke]. Early confirmations include locomotor ataxia with icy coldness, Raynaud-like attacks, numbness of extremities with blue nails, and obstinate constipation with dryness [Clinical], [Clarke], [Boericke].

Heloderma is the portrait of depressed “vital heat” with peripheral vaso-motor failure and neural numbness: icy coldness, blue nails, staggering at first motion, a slow, faltering heart, and mucosal dryness. The animal (reptile) signature presents as a metabolic slowness—the organism seems to slip toward torpor whenever exposed to cold. Psychologically there is little dramatic theatre: the mind mirrors the body’s state—apathetic, torpid, and worried chiefly when the precordium feels cold and the heart seems to pause. Once warmth returns, confidence and clarity follow, underscoring that the mental disturbance is reactive, not constitutional, in most cases [Clarke], [Farrington]. The central polarity is coldness with intermittent local burning: patches of burning in a field of ice, or pricking sparks as circulation returns to numbed terrain. This polarity appears in the skin (burning spots amidst chilblained cold), tongue (burning and numb areas), and peripheries (tingling burning after friction), confirming a syco-syphilitic dynamic of spasm and tissue under-nutrition [Clarke], [Phatak].
Kingdom reasoning (Animal—reptile) helps: reptilian metabolism and cool-blooded imagery translate clinically into low temperature tolerance, slow heart, and reliance upon environmental heat. The miasmatic tint is syphilitic (degenerative vascular disease, threatened apoplexy) with a sycotic pattern of recurrent vasospasm (Raynaud’s) and psoric dryness of mucosae. The pace is chronic-relapsing and weather-bound; the patient is especially vulnerable in cold, damp or windy seasons. The genius is found in two triads. First, the “temperature triad”: (1) cannot get warm; (2) worse uncovering, cold air, damp cold; (3) better heat, hot drinks, friction, sun. Second, the “neuro-gait triad”: (1) numbness and crawling; (2) staggering, walking on pads/pebbles, worse first motion; (3) steadier after warming with gentle steady movement. These are echoed throughout the case: Head (cold vertigo), Heart (precordial coldness, slow pulse), Mouth/Throat (dryness wanting hot drinks), Rectum (dry stools), Extremities (icy cyanosed digits), Skin (chilblains/frost-bite sequelae) [Clarke], [Boericke], [Boger].
Differentially, Heloderma stands apart by its relentless desire for warmth and friction. Camphor and Secale may be as cold, but they reject heat (Camph.) or manifest burning-with-cold with restlessness and often aversion to covering (Sec.). Carbo-veg. wants air and is asphyxial; Heloderma is thermo-circulatory with ataxia. Agaricus shares post-frost-bite states and incoordination but is twitchy, jocular, and cutaneous, while Heloderma is heavy, numb, cardiac. Gelsemium has ataxia, but not the primeval ice. The practising physician should listen for: “My hands go dead and blue in any breeze,” “I stagger until I warm up,” “Hot drinks and sitting by the fire bring me back,” “My heart feels cold and slow.” When that story repeats across systems, Heloderma often unlocks the case [Clarke], [Farrington], [Boericke].

• Peripheral nerves and posterior columns—paresthesias, numbness, and ataxic gait; “walking on pads/pebbles,” staggering and uncertainty in the dark (see Extremities, Generalities). [Allen], [Boger], [Clarke].
• Vaso-motor system—arteriolar spasm with pallor/blue nails; Raynaud’s pattern; chilblains/frost-bite sequelae (see Skin, Extremities). [Clarke], [Boericke], [Phatak].
• Heart and large vessels—bradycardia, intermittency, precordial coldness, angina pectoris, arteriosclerosis; threatened apoplexy (see Heart, Chest). [Clarke], [Boericke], [Boger].
• Temperature regulation—“vital heat” depressed; objective and subjective icy coldness; inability to get warm (see Generalities, Chill/Heat/Sweat). [Hering], [Boericke].
• Mucous membranes—marked dryness (mouth, throat), black or parched tongue, intense thirst for warm drinks (see Mouth, Throat, Stomach). [Clarke], [Boericke].
• Spine and cerebellar coordination—uncertain steps, swaying, worse on first rising or in cold air (see Back, Extremities). [Allen], [Boger].
• Skin and acral trophic beds—cyanosed tips, fissuring, senile pruritus with coldness; burning spots alternating with numbness (see Skin). [Clarke], [Phatak].
• Gastro-intestinal tract—sinking at epigastrium, obstinate constipation with dry, light-coloured stools; little urging (see Stomach, Rectum). [Boericke], [Phatak].
• Head/ears (labyrinthine circulation)—vertigo with chilliness; staggering as if drunk; Menière-like pictures in cold, draughts (see Head, Ears). [Clarke], [Boger].

The mental state is conditioned by the temperature and circulation. There is slowness of thought, torpor, and a blank, apathetic feeling when the chill predominates, as if mind and body were equally benumbed [Clarke], [Allen]. Anxiety appears during icy waves, with fear of collapse about the heart and a sinking at the pit of the stomach; this fear is practical rather than hypochondriacal, and it subsides as warmth returns (cross-reference: Better warmth, hot drinks) [Clarke], [Boericke]. Irritability arises when uncovered extremities provoke tingling pain; the patient becomes protective, wraps the hands, and avoids trivial tasks that require exposure (echoing Worse uncovering) [Clarke]. Concentration is poor during bouts of numbness: words are sought slowly, memory feels “cold and sluggish,” and mental clarity improves near a fire or in the sun (Better warmth, sun) [Phatak], [Clarke]. Depression is not profound in a constitutional sense; rather there is a discouraged mood from long-standing incapacity, especially the inability to keep warm or to walk steadily in the cold. A timid caution characterises movement (“I dare not cross the room without support”), which relaxes once warmth and circulation lift the ataxia (Better after warming, gentle steady motion) [Boger], [Clarke]. Sudden noises or emotional starts may intensify trembling in the cold; after the chill, the mind is tranquil and even mildly drowsy (Sleep improved after warmth) [Clarke]. Mini case: “Elderly man with winter angina and Raynaud’s; during cold paroxysms anxious, despairing of relief; Heloderma restored warmth and the anxiety vanished with the thaw” [Clinical], [Clarke].

Sleeplessness arises because the patient “cannot get warm.” He tosses for heat, finally sleeps after hot drinks, hot-water bottle and close wrapping (Better warmth) [Boericke], [Clarke]. Sleep is shallow and broken by waves of chill or by numb, tingling limbs. Dreams are of falling or staggering (ataxic echo) or of being out in icy wind (Dreams). After proper warmth, short naps refresh disproportionately (Better short sleep after warmth). On waking in a cold room, the unsteady gait returns until he warms again (Worse morning on rising, Better gentle steady motion after warming) [Boger].

Dreams of falling, tottering, and walking on uneven ground recur in cold seasons; the dream content mirrors the daytime ataxia (Extremities) [Clinical]. Dreams of ice or being frozen occur during night chills; they cease as the patient sleeps warm and steady. No strong erotic or anxious dream-life belongs to the remedy outside the collapse motif.

Heloderma synthesises objective and subjective coldness with numbness, ataxia, and circulatory depression. The modalities are stark and constant: worse cold, cold air, damp wind, uncovering, and first motion; better by warmth, hot drinks, friction, wrapping, sun, and gentle movement after warming [Clarke], [Boericke], [Boger]. The polarity of burning spots within great coldness is characteristic (Skin), as is the staggering gait at the outset of movement (Extremities). The heart is weak and slow, with precordial coldness; the nervous system is torpid, the mucosae dry, the bowels sluggish (Heart, Mouth/Throat, Rectum). Miasmatically the picture reads syphilitic degeneration with sycotic vasospasm. Compare Secale (cold yet cannot bear covering—opposite), Camphor (icy but averse to heat—opposite), Carbo-veg. (collapse needing air), Agaricus (ataxia with twitchings), and Gelsemium (drowsy ataxia without the intense coldness). Selection rests on the “icy-numb-ataxic” triad and its unwavering demand for heat and friction [Clarke], [Boericke], [Boger].

The febrile cycle is reversed: chill predominates, heat is scant, and sweat is cold and clammy (collapse profile) [Boericke]. There may be local burning spots within the general coldness. Temperature can be sub-normal. Any fever that does occur is low and followed by weakness rather than reaction. Angina or vertigo may complicate chills in the elderly (Heart/Head).

Chill is the essence—prolonged, penetrating, unrelieved without active heat measures [Hering], [Clarke]. Heat is partial or in patches; cold sweat appears on the forehead or extremities. The patient dreads uncovering even a hand; draughts provoke a fresh wave of numbness (Worse uncovering, Worse draughts). With recovery, a gentle glow spreads, and strength returns.

Vertigo is prominent, especially on first rising, in cold rooms, or when stepping into a draught; the patient staggers as if drunk, often compelled to sit or hold the wall [Clarke], [Boger]. Heaviness at the occiput with a sensation of chill at the vertex is noted; headaches are not violent but dull, benumbing, and coincide with general coldness (worse cold, better warmth) [Clarke], [Boericke]. A peculiar feeling as if the brain were “too cold” or as if cold water ran over the scalp fits the remedy’s temperature keynote [Hering], [Clarke]. When the chill passes, a glow may be felt in spots, alternating with numbed areas, reflecting the peripheral “burning-in-cold” polarity of this remedy (Skin cross-reference) [Clarke]. Stooping in the cold renews giddiness, while steady walking after warming lessens it (Worse first motion, Better gentle steady motion) [Boger]. Mini case: “Woman with winter vertigo on opening the street door; staggering until she reached the fire—Heloderma removed the doorway giddiness and fear of falling” [Clinical], [Clarke].

Vision dims with chill; letters blur until the patient warms, speaking to transient circulatory paresis of the ocular apparatus [Clarke]. Lids feel heavy, as if the palpebral muscles were numbed, opening sluggishly in cold air (Worse cold air, Better warmth) [Clarke], [Allen]. The conjunctiva is dry; lacrimation is scant, matching the general dryness of mucosae seen in Mouth/Throat. A sensation of cold air moving over the eyeballs may be described—rare but characteristic in remedies of depressed “vital heat” [Hering], [Clarke]. Photophobia is not typical; instead, the eyes “wake up” with warmth and friction. Any ocular flutter is secondary to systemic chill; as warmth returns, steadiness and acuity improve (explicit echo to Better warmth, rubbing) [Clarke].

Roaring or rushing noises may follow sudden chills, as if the labyrinthine circulation were checked; this dizziness is worse on rising in the cold and better after warming quietly in a chair (Head/Ears cross-reference) [Clarke], [Boger]. The pinnae are blue-cold and exquisitely sensitive to air; covering them tightly relieves (Worse uncovering, Better wrapping) [Clarke]. There is little otalgia; numbness rather than pain dominates. Hearing is duller during chill, recovering with heat. Menière-like turns—noise, staggering, pallor—show Heloderma’s reach where cold and circulation lie at the root (compare Gels., Agar.) [Clarke], [Boger].

The nose is dry and cold, sometimes with a sensation as if icy air flowed continually through it; coryza is not a keynote, but the mucous membrane shares the general dryness [Clarke], [Boericke]. Smell may be blunted during chill and returns with warmth. Cold draughts at the nostrils can trigger generalized shudder and vertigo (Worse cold air, Better warmth) [Clarke]. Epistaxis is rare. The nasal tip is blue or livid in wind, recovering on rubbing and warmth (Skin/Extremities cross-reference) [Phatak].

Facial pallor with a faint bluish tinge of lips and nails in cold attacks is common; the face warms slowly and tingles as circulation returns (Better warmth, rubbing) [Clarke]. Neuralgic facial pains are less frequent than numbness; when present, they are prickling and chill-bound, better heat. The jaw may tremble in severe cold; speech is deliberate from lingual dryness and numbness (Mouth). Emotional embarrassment from cyanosed fingertips at table can contribute to discouragement (Mind). In cold winds, the cheeks feel as if glazed with “glass-cold,” a vivid sensory keynote of Heloderma (compare Camph., Secale) [Clarke], [Boericke].

Mouth and tongue are dry, parched, sometimes described as blackish or heavily coated; thirst is for hot drinks which give transient revival (Better hot drinks) [Boericke], [Clarke]. Taste is blunted; the tongue feels numbed and speech slow, consonants indistinct when very cold (Worse cold, Better warmth) [Clarke]. Saliva is scant; there is no notable sialorrhœa. Burning spots may alternate with numb patches on the tongue, the same polarity seen in the skin. As general warmth returns, moisture and articulation improve, mirroring the generalities [Clarke], [Allen].

The dental sphere is secondary. Cold air striking the teeth causes prickling, momentary neuralgia and jaw stiffness; warm rinses ease (Worse cold air, Better warmth) [Clarke]. Grinding of teeth is not characteristic. Gums are pale and retracted in chronic chillers; bleeding is not typical as in Merc. If constipation and gastric sinking are present, the patient may avoid cold water on the teeth due to the “stomach goes cold” sensation (Stomach cross-reference) [Boericke].

The throat feels glass-dry, as if frozen; swallowing is difficult chiefly from dryness and muscular sluggishness, not acute pain [Clarke], [Boericke]. Warm drinks and slowly sipping hot water restore comfort and confidence (Better heat, Better hot drinks). There is little catarrh; voice may be thin or tremulous in cold. In chill paroxysms, the thyroid and front of neck feel cold to the touch (Heart/Chest analogue of precordial coldness) [Clarke].

Constriction with a sense of precordial coldness is distinctive; patients clutch the chest, seek heat, and fear the heart may stop (Mind/Heart cross-reference) [Clarke], [Boericke]. Breathing is shallow during chill; deep breaths are taken cautiously until warmth returns. Stitching pains are uncommon; rather there is heavy, cold tightness. Cold air on the chest intensifies the feeling of cardiac insufficiency (Worse cold air). Heat over the chest soothes remarkably (Better warmth), a prescribing pointer in anginoid cases [Clarke].

Pulse is slow, sometimes intermittent; the heart seems to pause, with a blank, sinking feeling in the epigastrium and icy sensations across the precordia [Boericke], [Clarke]. Angina pectoris with profound chill is an indication; warmth, rest, and pressure give comfort (Better warmth, pressure) [Clarke]. Arteriosclerosis and threatened apoplexy are mentioned by several authors, placing Heloderma among remedies for senile vascular states with coldness and numbness (compare Bary-c., Sec., Carbo-v.) [Clarke], [Boger]. Palpitations are not violent; the keynote is power failure with cold sweat. After warming, the pulse steadies and fear subsides.

Respiration is diminished in amplitude during chill, but not asthmatic; there is no wheeze. Cold air to the larynx aggravates shallow breathing; covering the mouth and nose helps (Nose/Throat echo). A sigh may herald returning warmth and confidence. The respiratory sphere thus follows the heart-temperature axis [Clarke].

A characteristic sinking at the epigastrium accompanies cold waves, with nausea and faintness; it is relieved by hot drinks and heat to the pit of the stomach [Boericke], [Clarke]. Appetite is low during chill but returns with warmth. Eructations may be cold and empty; alcohol or iced drinks aggravate both nausea and the sense of internal cold (Worse cold drinks) [Clinical]. The epigastrium feels iced; placing a hot bag there steadies the heart and lessens anxiety (Heart/Stomach cross-reference) [Clarke]. Vomiting is uncommon; the keynote is collapse-like sinking more than gastric irritability.

Abdomen is chilly to the patient’s perception; peristalsis seems torpid (echoing the global “vital heat” depression) [Clarke]. Colic is unusual; flatulence is not distinctive. The abdomen is better with external heat. Constipation belongs rather to the rectal sphere than to colic. A feeling of internal cold air moving across the lower belly may be reported during draughts (Generalities) [Hering].

Obstinate constipation with dry, light-coloured stools and little urging is a clinical keynote, reflecting general dryness and neuromuscular torpor [Boericke], [Phatak]. Evacuation leaves weakness and yet some relief of epigastric sinking (Better after stool—partial) [Phatak]. Haemorrhoids are not prominent; fissuring in chilblain-type skin may appear at the anal margin in extreme cold (Skin analogy). The constipation often improves when the patient spends time in warmth and takes hot fluids, echoing the core modality.

Scanty urine during chill; output increases after warmth. There may be slow micturition from sphincter sluggishness in cold; no violent tenesmus or burning. Urine is pale; albuminuria is not a keynote. The bladder feels numb rather than irritable, consistent with the nerve picture [Clarke].

Marked desire for hot drinks and warm soup; aversion to cold water (Worse cold drinks) [Boericke], [Clarke]. Appetite is small during chill, with sinking at epigastrium. Alcohol aggravates faintness and chill. Spices that warm are often welcomed; ices are shunned instinctively.

Libido and function are depressed during cold, with numb genital sensation; warmth and circulation restore confidence (functional, not a primary genito-urinary remedy) [Clinical]. No specific urethral catarrh or prostatism belongs to Heloderma in classical texts.

Menses may be delayed in severe cold exposure; cramps are not characteristic. Chilblain-prone fingers worsen premenstrually in some, reflecting vaso-motor lability (Skin). Not a uterine remedy per se; selection remains on vascular-neural keynotes [Clarke].

A sensation of cold along the spine or between the shoulder-blades appears in chills; lumbago-like aching may accompany cold damp weather (Rheumatic echo) [Boericke], [Clarke]. Stiffness on first rising, with unsteadiness until warmed, links spine to cerebellar/coordination features (Extremities). Heat to the back and slow mobilisation relieve (Better warmth, Better gentle motion) [Boger].

Cardinal sphere. Hands and feet are “ice-cold,” nails blue; digits go numb and dead in wind or damp cold, reviving with heat and friction (Raynaud-like) [Clarke], [Phatak]. Sensations include walking on pads or pebbles, soles swollen though not so, or sore as if beaten, with uncertain steps and staggering when first starting (posterior column/coordination analogy) [Allen], [Boger]. Cramps in calves and flexing of toes occur during chill; tight shoes aggravate. Trembling accompanies chill and lessens as warmth returns (explicit echo to Better warmth, rubbing). Peripheral neuritis with crawling, formication and coldness belongs here; the remedy has aided frost-bite sequelæ and stubborn chilblains where burning alternates with numbness [Clarke], [Boericke]. Mini case: “Old fisherman with blue toes every winter, unable to feel the boards; Heloderma in low potency with heat and friction ended the season’s cycle” [Clinical], [Clarke].

Skin over acral parts is cyanosed, livid or mottled in cold; burning spots may alternate with a prevailing glass-cold numbness—this alternation is peculiarly Heloderma [Clarke], [Phatak]. Chilblains fissure, itch or burn while the general sensation remains cold; warmth and rubbing restore comfort (Better warmth, friction). Sequelæ of frost-bite—formication, deadness, relapse in damp cold—are classical indications. Senile pruritus with coldness, worse in the evening and cold air, may respond when the temperature keynote is marked [Clarke]. The skin is otherwise dry, without much sweat except cold clamminess in collapse.

• Aetiology / Vaso-motor & Cold
– Secale cornutum: objective coldness and cyanosis, but aversion to covering and often burning pains; Heloderma craves warmth and friction, with numbness and ataxia. [Clarke], [Boger].
– Camphora: icy collapse with lividity; Camphor cannot tolerate external heat; Heloderma improves markedly by heat and rubbing. [Boericke], [Clarke].
– Carbo vegetabilis: collapse, cold sweat, wants air fanned; Heloderma’s keynote is heat-craving and ataxia rather than dyspnoeic asphyxia. [Clarke], [Nash].
• Nervous System / Ataxia
– Agaricus: incoordination with twitching, frost-bite history; more “spasmodic” and jocular mental state; Heloderma heavier, numb, profoundly cold. [Boger], [Kent].
– Gelsemium: weakness, trembling and ataxia with drowsiness; less peripheral cyanosis and cold extremities than Heloderma; heat desire is not central in Gels. [Farrington], [Clarke].
– Plumbum: paralysis with constipation; Plb. has drawing, retractive pains and lead colic; Heloderma’s hallmark is coldness with numbness and staggering at first motion. [Allen], [Boger].
• Cardio-vascular / Angina–Arteriosclerosis
– Cactus grandiflorus: constriction “as if iron band”; less coldness; Heloderma adds precordial icy sensation and slow pulse. [Clarke], [Boericke].
– Baryta carbonica: arteriosclerosis in elderly with chilliness and childishness; Heloderma more peripheral cyanosis/ataxia picture; Bary-c. more mental immaturity. [Kent], [Clarke].
– Tabacum: deathly nausea with cold sweat and sinking; Tab. has relief from fresh air and open air, often better cold air; Heloderma is worse cold air and needs heat. [Clarke], [Nash].
• Skin / Raynaud–Chilblains–Frost-bite
– Petroleum: fissured chilblains worse winter, less general collapse; Heloderma has icy numbness with ataxia and cardiac features. [Clarke], [Boger].
– Agaricus (again): chilblains with itching-burning and choreic twitchings; Heloderma numb-cold with burning “spots,” improved by intense heat and friction. [Boger].
– Secale (again): dry gangrene tendency in severe vaso-spasm; Heloderma earlier, functional Raynaud-type with heat-craving. [Clarke].
• Digestive / Dryness with Collapse
– Veratrum album: cold collapse with copious vomiting/diarrhœa and desire for cold drinks; Heloderma has dryness, constipation, and wants hot drinks. [Boericke], [Clarke].
– Arsenicum album: anxiety with burning pains, restlessness, and chilliness better heat; Arsen. is more restless, burning, and anxious; Heloderma is more numb, heavy, ataxic, with slow pulse. [Kent], [Clarke].
• Micro-comparisons
– Carbo-veg. vs Heloderma: both collapse; Carbo-veg. wants air and is often better cool air; Heloderma is worse air/cold and incessantly seeks warmth/friction. [Nash], [Clarke].
– Camph. vs Heloderma: both icy; Camph. cannot bear heat; Heloderma recovers by heat—decisive. [Boericke], [Clarke].

• Complementary: Agaricus—frost-bite and chilblain constitutions; Agar. covers itching-burning and twitchings; Heloderma covers numb-cold ataxia. [Boger], [Clarke].
• Complementary: Baryta carbonica—senile vascular states; Heloderma for icy numbness/ataxia, Bary-c. for arterial degeneration and childishness. [Kent], [Clarke].
• Complementary: Calcarea fluorica—peripheral trophic changes (chilblains, brittle nails) alongside Heloderma’s vaso-spasm. [Clarke], [Boericke].
• Follows well: Gelsemium—after febrile debility with ataxia when intense coldness appears. [Farrington].
• Follows well: Carbo vegetabilis—post-collapse convalescence when heat-craving and numbness predominate. [Nash], [Clarke].
• Precedes well: Secale—if the case evolves toward dry gangrenous tendencies despite heat-craving, change to Secale. [Clarke], [Boger].
• Related: Camphora—antipodal heat modality clarifies choice in icy collapse; avoid alternating routine. [Boericke], [Clarke].
• Related: Veratrum album—collapse remedies; distinguish GI storm (Verat.) from dry numb-cold (Helod.). [Clarke].
• Related: Arsenicum album—both chilly; Arsen. restless/burning; Heloderma numb/ataxic with slow pulse. [Kent].
• Related: Tabacum—sinking with cold sweat; Tab. often relieved by cool air; Heloderma is worse. [Clarke].
• No clear inimicals noted in classical texts; individualise and heed modalities. [Clarke], [Boericke].

Indications: Raynaud’s phenomena; chilblains and frost-bite sequelae; peripheral neuritis with numbness and crawling; locomotor ataxia-like gaits aggravated by cold; senile arteriosclerosis with cold spells and slow pulse; angina pectoris with precordial coldness; collapse states with dryness of mucosae and obstinate constipation [Clarke], [Boericke], [Boger], [Phatak]. Potency/posology: Many authors favour low to medium potencies (3X–6X–12C) in persistent peripheral trophic troubles, repeated once to thrice daily for several weeks, watching for improvement in temperature tolerance and colour of digits; higher potencies (30C–200C) may be used for functional ataxia and anginal chill paroxysms with careful observation of the heart rhythm [Clarke], [Boericke], [Farrington]. Repetition: Reduce when warmth, steadier gait, and stool frequency improve; intermit during hot seasons. Adjuncts: rigorously apply heat, friction, and protective clothing; avoid damp cold; hot beverages taken regularly; gentle graded mobilisation once warm (explicitly matching the modalities).
