Hydrastis canadensis

Hydrastis canadensis is a perennial of the Ranunculaceae native to North America. The rhizome contains isoquinoline alkaloids—chiefly berberine, hydrastine, and canadine—together with resin and bitter principles that explain much of its pharmacology: tonic-astringent effects on mucous membranes, antimicrobial action, and influence on smooth muscle and secretory tone [Hughes], [Clarke]. In homœopathy the mother tincture is prepared from the fresh rhizome; triturations and centesimal dilutions follow standard methods [Allen], [Clarke]. Toxicology and physiological study show depression of mucosal vitality with viscid, tenacious, yellow or “ropy” secretions and a tendency to atony, which is precisely the pathologic field in which Hydrastis earns its reputation—chronic catarrhs (nasal, pharyngo-laryngeal, gastro-intestinal, genito-urinary), atonic dyspepsia with “goneness” at the epigastrium, obstinate constipation from rectal torpor, fissures and hæmorrhoids, and cachectic states bordering upon malignant disease (as an intercurrent or palliative where mucosal ulceration and induration are present) [Hering], [Clarke], [Boericke]. The keynote “thick, tenacious, yellow, stringy mucus” runs like a golden thread through the remedy picture, linking nose, throat, bronchi, stomach, cervix, urethra, and skin ulcers [Boger], [Farrington].

Hydrastis did not undergo a large Hahnemannian proving; its pathogenesis was assembled from smaller provings, clinical confirmations (especially American), toxicologic notes, and the Eclectic tradition [Allen], [Hering], [Clarke]. Early confirmations include post-nasal catarrh with hawking of thick, tenacious mucus; atonic dyspepsia with epigastric “goneness” not fully relieved by eating; obstinate constipation with rectal torpor and fissure; old-people’s bronchitis with scant energy to expectorate “stringy” sputum; and ulcerative mucous states in mouth, cervix, and rectum [Clarke], [Boger], [Boericke], [Farrington]. [Proving] and [Clinical] tags are interwoven throughout the picture by the classical authors cited.

Hydrastis is the remedy of the sluggish mucosa—flabby, atonic, secreting either too little or, more typically, a thick, tenacious, yellow, ropy mucus that clings to surfaces and demands mechanical effort to expel. The same secretion recurs from nares to bronchi, mouth to cervix, rectum to ulcer base, creating a unifying “material” keynote that simplifies prescribing when recognised [Clarke], [Hering], [Boger]. The organism feels “empty” and “gone” at the epigastrium, yet heavy after food; torpor replaces irritability; weakness speaks louder than pain. This explains the mental picture—dull, peevish, discouraged, averse to exertion—without suggesting a deep constitutional psychodynamics: Hydrastis is regional and functional, not a grand temperament. The kingdom signature (Plant—Ranunculaceae) appears as mucosal and cutaneous reactivity with chronicity rather than explosive inflammation. Miasmatically, sycotic overgrowth (polyps, cervical erosion, glandular enlargement) marries syphilitic tendencies (fissures, ulcers, indurations), while psoric fatigue underlies “goneness” and early exhaustion; thus the remedy finds itself in borderlands—pre-malignant states, senile cachexia, long-standing catarrhs—and tones them rather than reconstructs the entire constitution [Clarke], [Farrington], [Boericke].

The pace is slow and the modalities are homely: warmth, warm drinks, warm bathing, small warm meals; gentle motion after rest; avoidance of cold, damp, and sudden temperature change; relief after hawking or expectorating ropes; partial solace from eating; and aggravation on waking with the mouth foul and the head heavy. These recur in every sub-section, compelling confidence in selection. Compare Kali-bichromicum in acute, mapping sinus disease with “plug” expulsions; Mercurius where heat, salivation, and offensive ulceration dominate; Sepia when pelvic relaxation coexists with moral indifference rather than dull peevishness; Pulsatilla when bland catarrh and gentle weeping predominate; and Lycopodium when the right hypochondrium and gas decide the case [Clarke], [Boger], [Farrington], [Kent]. Hydrastis does palliative but potent work in gastric, cervical, and rectal malignancies—not as a curative monotherapy but as a remedy easing fœtor, discharge, and torpor, improving appetite and sleep, and restoring dignity (a point made again and again by Clarke and Boericke) [Clarke], [Boericke].

Practically, the physician listens for the patient who says: “Every morning I wake foul and must hawk long strings before I can think,” “Food helps for a while, then sits like lead,” “My bowels are lazy; the stool is large and fissures me,” “Threads of mucus are in everything—nose, throat, chest, even the urine,” and “Warm drinks calm my throat.” Where these sentences braid together, Hydrastis is rarely wrong. The art then is to set expectations: chronic catarrh alters slowly; dosing and homely measures (warmth, hygiene, gentle motion) must work together, and when they do, discouragement recedes with the mucus. That is the quiet genius of Hydrastis [Clarke], [Farrington], [Boericke].

• Mucous membranes (pan-catarrhal)—nose, post-nasal space, pharynx, larynx, bronchi: thick, tenacious, yellow, ropy mucus; rawness, hawking; voice husky (see Nose, Throat, Respiration). [Clarke], [Boger], [Boericke].
• Gastro-duodenal mucosa—atonic dyspepsia; “goneness” at epigastrium; gastric catarrh; ulcer tendency; coated, large “mapped” or flabby tongue; bitter taste (see Stomach). [Hering], [Clarke], [Farrington].
• Hepato-biliary system—congested liver, bilious headaches, clay-coloured stools; post-cholecystic catarrh (see Abdomen, Stomach). [Clarke], [Boger].
• Rectum and anus—torpor; large dry stools; fissures and hæmorrhoids; soreness and pruritus; mucous oozing (see Rectum). [Clarke], [Boericke].
• Female pelvic organs—cervical erosions; stringy yellow leucorrhœa; prolapse and subinvolution in relaxed states (see Female). [Clarke], [Farrington].
• Oral cavity—stomatitis, aphthæ, pyorrhœa; stringy saliva; foul taste morning (see Mouth, Teeth). [Hering], [Clarke].
• Skin and ulcers—indolent ulcers with thick, yellow secretion; fissures (nipple, anus); eczema of folds (see Skin). [Clarke], [Boger].
• Lymphatics and nutrition—cachexia; emaciation in the aged; “old people” remedy for catarrhal weakness (see Generalities). [Boericke], [Clarke].
• Genito-urinary tract—catarrh of bladder/prostate with ropy mucus in urine; dribbling in old men (see Urinary, Male). [Clarke], [Phatak].

Hydrastis reflects the psychology of chronic catarrh and digestive depression rather than a flamboyant constitutional portrait. The patient is low-spirited, fretful, and easily discouraged, with a dull, besotted feeling as if the head were “thick” and the mind moved through mucus; work seems an effort until the stomach is steadied [Clarke], [Farrington]. There is anxiety about health, disproportionate to strength rather than hypochondriacal fantasy; the fœtid breath and constant hawking create social self-consciousness, increasing irritability at trifles (cross-reference Worse morning, foul taste; Worse talking) [Clarke]. Brain-fag appears after short mental effort, with heavy eyelids, frontal pressure, and the desire to lie quiet—an echo of general atony [Hering], [Clarke]. The temper is softened by relief of the mucous burden—after a warm drink, food, or successful expectoration the patient becomes less peevish (Better warm drinks; Better eating) [Clarke], [Boericke]. A peculiar feature is the disproportion between subjective weakness and objective disease: the sufferer feels profoundly unwell from functional catarrh and torpor, yet there is little fever; this mismatch fosters gloom and a premonition of serious illness (often disproved when tone returns) [Clarke], [Boger]. Memory is sluggish; he repeats himself, forgets small errands, and loses the thread of conversation, particularly on rising with coated tongue and ropy throat (Worse morning) [Clarke]. Sleep deprivation from nocturnal hawking magnifies irritability next day (Sleep cross-link). Mini case: “Bookkeeper with constant hawking, foul morning taste and ‘gone’ stomach—Hydrastis 6X brightened mood as post-nasal catarrh yielded” [Clinical], [Clarke].

Sleep is broken by hawking and cough; the patient dozes lightly, wakes with a foul mouth and must clear the post-nasal ropes before returning to rest (Worse morning; Nose/Throat) [Clarke]. Snoring or mouth-breathing from nasal obstruction disturbs bed-partners; humidified air and warm drinks at bedtime help (Better warmth) [Clarke], [Boericke]. The sleep is unrefreshing in proportion to digestive torpor; after a small warm meal and gentle walk, sleep improves (Stomach/Generalities). Dreams of business or of choking on mucus occur; restlessness abates as secretions loosen. Daytime drowsiness follows night coughing and lifts when the chest is cleared. Naps refresh more than long sleep, which thickens mucus if the room is cold. The overall sleep picture is secondary to mucosal load and atony, improving exactly with modalities that palliate these [Clarke], [Farrington].

Dreams of suffocation, of speaking but being unable to clear the throat, or of eating tasteless food that lies heavy recur in Hydrastis sleepers; such content diminishes as gastric and naso-pharyngeal spheres improve [Clinical], [Clarke]. Domestic/work anxieties mirror the dull mental state; there are no vivid terrors or sexual dreams peculiar to the remedy.

Hydrastis synthesises a pan-catarrhal atony of mucous membranes with viscid, stringy, yellow secretions, a “gone” epigastrium, rectal torpor with fissures, and sluggish ulceration in skin and cervix—especially in the elderly, cachectic, or “run down” [Clarke], [Boericke], [Boger]. Modalities echo everywhere: worse morning; worse cold, damp, and sudden temperature changes; worse talking and mental effort during catarrh; better warm drinks, small warm meals, gentle motion after rest, and warm bathing of affected parts. The remedy’s pace is slow; it convalesces, dries fœtor, and restores tone rather than overturns acute storms (contrast Merc. in septic mouth or Kali-bi. in acute sinus plugs) [Farrington], [Clarke]. Miasmatically, sycotic hypertrophy and ropy secretions sit beside syphilitic fissure/ulcer, with psoric prostration—the triad seen in chronic nasal, gastric, cervical, and rectal disease. Choose Hydrastis when the same yellow, ropy thread stitches together complaints at different orifices and when “goneness” plus torpor rule the day [Clarke], [Hering], [Boger].

Hydrastis has little febrile identity; chilliness and low evening heat may occur with catarrh or gastric upset, but true fever suggests intercurrent infection or a different remedy [Clarke]. Night sweats in cachectic states are possible; they are not diagnostic. Temperature changes aggravate catarrh—hence the clinical attention to clothing and room climate (Modalities) [Clarke], [Boericke].

Chilliness in cold, damp weather sets off catarrh; heat is partial (face flushed) in stuffy rooms; sweat is slight unless cachectic [Clarke]. Cold air on throat worsens hawking; warm, moist air soothes (Throat). Night sweats attend debility but yield as nutrition and digestion mend. Hydrastis is about secretion, not thermic storms.

Frontal, dull, pressing headaches are common, especially above the root of the nose, with a sensation of weight that compels frowning; they are worse in cold, damp air and with sudden changes of temperature, better in mild open air and after discharging thick mucus (Nose cross-link) [Clarke], [Boericke]. The scalp may feel tight, with a “band-like” compression, and the head is muddled until the morning hawking is accomplished (Worse morning; Better warm drinks) [Clarke]. Sick headaches of bilious origin accompany gastric torpor, with nausea, coated tongue and bitter taste; small, warm meals and rest relieve (Stomach linkage) [Boger], [Clarke]. Vertigo is not violent but occurs on rising or with fasting, corresponding to the “goneness” at epigastrium and general weakness; it lessens after eating (Better eating) [Clarke], [Farrington]. Catarrh of frontal sinuses leads to tenderness at the supraorbital ridges; firm pressure gives momentary ease as mucus is stirred (Nose). The cranial picture is thus catarrhal-bilious rather than neuralgic, tracking the tides of mucus and bile [Clarke], [Boericke].

Catarrhal conjunctivitis with thick, yellow, stringy discharge and raw, smarting lids suits Hydrastis, especially when nose and throat share the same ropy theme (Nose/Throat concordance) [Clarke], [Hering]. Marginal blepharitis with crusts in the morning, lids stuck together, and relief from gentle bathing in warm water (Better warm bathing) is classical [Clarke], [Boericke]. The cornea may ulcerate sluggishly in cachectic states; discharge is bland-viscid rather than acrid-scorching (contrast Euphr.) [Clarke]. Vision blurs with frontal congestion and clears as the catarrh is expelled; reading in the morning is difficult until the hawking ritual is complete (Worse morning) [Clarke]. Photophobia is slight; the dominant sensation is dryness with strings of mucus across the palpebral fissure. Mini case: “Elderly woman with blepharitis, stringy discharge, and post-nasal hawking—Hydrastis with warm lid bathing ended morning crusts in a week” [Clinical], [Clarke].

Eustachian catarrh with blocked sensation, diminished hearing, and popping on swallowing follows naso-pharyngeal mucus; thick post-nasal strings are the herald [Clarke]. Otorrhœa is not a keynote, but a viscid, non-irritating discharge may occur after colds; relief follows improvement in the naso-pharynx (cross-reference Nose/Throat) [Clarke], [Boger]. Buzzing or roaring accompanies frontal catarrh and clears as the head lightens. Pain is dull, pressing; acute neuralgia belongs elsewhere. The ear picture is subordinate and conductive rather than neuro-sensory [Clarke], [Boericke].

This is a capital sphere. Thick, yellow, stringy mucus burdens the nares and post-nasal space; the sufferer is forever hawking ropes from the posterior nares, which leaves rawness and temporary relief (keynote) [Clarke], [Hering], [Boger]. The nose is sore, cracked at the wings, and the sense of smell is blunted; cold, damp air thickens the discharge and renews frontal pressure (Worse cold damp; Head linkage) [Clarke]. Crusts and scabs form high up; polypoid swellings may be present in long catarrhs (sycotic overgrowth) [Clarke]. Coryza is less fluent than stubborn; the keynote is tenacity. Morning is worst: mouth fœtid, tongue coated, hawking required before head clears (Worse morning; Better warm drinks) [Clarke], [Boericke]. Mini case: “Post-nasal ‘rope-puller’—Hydrastis 3X reduced stringy mucus and abolished daily hawking” [Clinical], [Clarke].

Sallow, cachectic, prematurely lined faces are frequent companions of Hydrastis states; bluish under-eyes reflect digestive torpor and catarrh [Clarke]. Acne rosacea with gastric derangement improves as stomach function returns; pustules are sluggish, discharging a yellowish, sticky matter (Skin linkage) [Clarke], [Boger]. Lips are dry, cracked; commissures fissure in wind; breath fœtid in the morning from oral catarrh (Mouth). Facial neuralgia is uncommon; frontal heaviness dominates. Improvement in facial colour is a clinical marker that the gastric and nasal spheres have yielded (Generalities) [Clarke].

Mouth and tongue mirror the stomach. Tongue large, flabby, coated yellow-white or “mapped,” with large indentations of the teeth; at times dry, at others clammy with stringy saliva [Hering], [Clarke]. Taste is bitter in the morning, fœtid breath annoys the patient and family; aphthæ appear with rawness, and ulcers ooze a viscid, yellow secretion (Skin concordance) [Clarke], [Boericke]. The palate and fauces feel denuded, sore; speaking provokes hawking of mucus threaded back from the post-nasal vault (Throat). Warm rinses relieve; cold drinks chill and thicken the mucus (Better warm drinks; Worse cold) [Clarke]. Pyorrhœa alveolaris with relaxed spongy gums improves when digestive catarrh is corrected; the oral cavity is not isolated but the front line of general mucosal atony [Clarke], [Boger].

Looseness of teeth and bleeding of relaxed gums accompany pyorrhœa; sordes collect in the morning (Worse morning) [Clarke]. Toothache is dull, worse cold liquids on sensitive teeth, better warm applications (modality echo) [Clarke]. Offensive mucus threads from pockets when gums are pressed; dental intervention gains by simultaneous correction of gastric and nasal catarrh (System linkage) [Boger]. Caries is slow; the mouth is fetid rather than acutely painful.

Raw, denuded feeling in the pharynx with constant desire to clear thick, tenacious mucus from the post-nasal space defines Hydrastis [Clarke], [Hering]. The uvula feels elongated; voice husky, worse on much talking or in cold rooms, better warm drinks (Worse talking; Better warm drinks) [Clarke], [Boericke]. Spasmodic hawking ends in a lump of yellow rope; relief is real but short-lived. Tonsils are less inflamed than coated; chronic pharyngitis of speakers and smokers belongs here, especially with gastric catarrh (Stomach linkage) [Clarke]. The throat “picture” repeats the remedy’s universal signature.

Old-people’s bronchitis with scant power to detach thick, tenacious yellow sputum is a classic indication; the cough is fatiguing, chest raw, and voice husky [Clarke], [Boericke]. Warm drinks, gentle steam, and patient coughing bring up tough “strings,” after which the head clears and fatigue abates (Better warm drinks; Better gentle motion) [Clarke]. Pains are dull; stitchy pleurisy is not characteristic. The chest resonates with naso-pharyngeal themes—when the post-nasal dam breaks, the bronchi follow [Boger], [Clarke]. Mini case: “Cachectic man with winter bronchitis—Hydrastis 3X and warm drinks enabled expectoration of ropes; night cough ceased” [Clinical], [Clarke].

Hydrastis is not a primary cardiac remedy; yet palpitations occur from weakness after meals or during gastric distress; pulse soft, easily quickened (functional) [Clarke]. Precordial anxiety accompanies gastric sinking, relieved by warm food and rest (Stomach cross-link). Senile debility with bronchitis may produce a tired heart that benefits indirectly as catarrh lifts. True angina belongs elsewhere.

Breathing is short from mucus load and chest fatigue; sighing after detaching a plug is common [Clarke], [Boericke]. Larynx raw, voice husky; speaking aggravates cough and hawking (Worse talking) [Clarke]. Expectoration is difficult until warmed, then comes in long strings, non-acrid, yellowish. Wheeze is less than rattle of sticky mucus. Relief is proportional to the amount of tenacious matter raised (modalities echoed).

Atonic dyspepsia with “sinking” or “goneness” at the epigastrium is classic; eating gives only partial, brief relief, after which a sense of weight and faintness returns [Clarke], [Farrington]. Nausea is morning or after rich, fatty foods; eructations sour or “tasteless wind,” with distension and frontal heaviness (Head linkage) [Boger], [Clarke]. Appetite capricious—hungry yet unable to digest; mouth tastes bitter and foul on waking; tongue flabby and coated (Mouth concordance) [Hering], [Clarke]. Gastric catarrh with thick, tenacious mucus and a tendency to sluggish ulceration makes Hydrastis valuable in chronic gastritis and as a palliative in gastric carcinoma, where “goneness,” cachexia, and viscid oozing are features (compare Kali-bi., Ars., Phos.) [Clarke], [Farrington], [Boericke]. Better for small, warm meals; worse bread, pastry, greasy food, and iced drinks (Modalities) [Boger], [Clarke]. Mini case: “Old man with ‘gone’ stomach, bitter morning taste, and ropey throat—Hydrastis 6X restored appetite and lifted frontal fog” [Clinical], [Clarke].

Liver enlarged or tender, with fullness under right ribs, clay-coloured stools, and bilious headaches point to hepato-biliary catarrh with deficient bile outflow [Clarke], [Boger]. The abdomen is gassy, with a tendency to loud rumbling after eating (atony); yet griping is rare, pain being dull and dragging. Sensation of “emptiness” coexists paradoxically with heaviness after meals—an atonic contradiction often met in Hydrastis [Clarke]. The mesenteric glands may be enlarged in scrofulous children with catarrh and emaciation; improvement of stools and appetite follows correction of gastric secretions [Clarke], [Hering]. Chronic constipation contributes to abdominal discomfort; support the bowels with gentle motion and warm fluids (Rectum cross-link) [Boger], [Clarke].

Obstinate constipation from rectal torpor is a hallmark: large, dry stools passed with great straining; fissures and hæmorrhoids result, with raw soreness and oozing of thick mucus [Clarke], [Boericke]. The anus cracks and bleeds; the part is painful for hours after stool; warm bathing and glycerine relieve (Better warm bathing) [Clarke]. There is constant sensation of incomplete evacuation; yet urging is feeble (atony). Pruritus ani from mucous oozing torments, worse in cold damp weather and when debilitated [Clarke]. Hydrastis often follows Nux when the acute irritability has subsided, to rouse the torpid rectum and heal fissures (Relationships) [Boger], [Clarke]. Mini case: “Fissure with thick mucus, large stools, and raw soreness—Hydrastis 3X with local warm bathing healed in three weeks” [Clinical], [Clarke].

Catarrh of the bladder with mucus and threads in the urine; difficult starting, dribbling, especially in old men with enlarged prostate [Clarke], [Phatak]. Urine is scanty, cloudy with mucus, sometimes with phosphates; urging is more torpid than painful. Burning is slight; the keynote is glairy mucus and atony of neck of bladder [Clarke]. Renal ache is dull; no violent nephritic colic. Improvement parallels correction of gastric and rectal torpor (general atony). In women, urinary leakage may accompany uterine relaxation and catarrh (Female link).

Aversion to fats, pastry, and rich dishes; desire for warm, simple food and warm drinks (goneness relieved) [Boger], [Clarke]. Milk may cause flatulence; bread lies heavy. Craves hot water or tea to loosen mucus (Throat). Alcohol and tobacco aggravate fœtor and catarrh. Appetite improves as digestion is roused and catarrh lightened.

Prostatic catarrh with dribbling after micturition, perineal weight, and ropy urethral mucus belongs to Hydrastis in the elderly [Clarke], [Phatak]. Sexual desire is lowered by digestive torpor; erections weak. Balanitis with sticky yellow discharge (non-corrosive) responds when general catarrh is treated. The male picture is catarrhal and atonic; acute urethritis with burning chooses other remedies.

Leucorrhœa thick, yellow, tenacious, and stringy—often ropy strands that stain linen—marks the female sphere; it is worse after exertion and when tissues are relaxed (post-partum, subinvolution, prolapse) and better for local warmth and general tone [Clarke], [Farrington]. Cervix eroded, raw, bleeding easily; the os feels denuded and sticky (sycotic overgrowth over syphilitic rawness) [Clarke]. Menses may be scant and delayed from atony or too profuse when pelvic congestion dominates; pains are dull and dragging. Pruritus vulvæ arises from the viscid discharge; scratch excoriates but does not burn like Kreos. Hydrastis acts as a palliative in mammary and uterine cancer where induration abuts ulceration and thick oozing is present—its role is supportive, not curative [Clarke], [Boericke]. Pelvic prolapse with constipation and gastric catarrh completes the triad (Rectum/Stomach cross-links) [Farrington].

Dorsal ache between shoulder-blades often accompanies gastric dyspepsia—an interscapular “drag” that eases after eructation or food (Stomach linkage) [Clarke], [Boger]. Lumbar weakness follows prolonged constipation and prolapse; warmth and rest relieve (Rectum/Female). The back tells the same tale: fatigue from atony, not violence from inflammation. Stooping increases post-nasal drip, provoking hawking and secondary back tension (Nose/Throat echo).

Limbs feel heavy and weak; hands tremulous in the morning until food and warmth are taken (Worse morning; Better eating) [Clarke]. Arthritic pains are not characteristic, though chronic catarrh may coexist with gouty subjects. Cold, damp weather stiffens joints and thickens catarrh together (Generalities). The extremities provide little decisive guidance beyond the global weakness of Hydrastis states.

Hydrastis is a slow-healing, thick-secreting ulcer remedy. Indolent ulcers with yellow, viscid, non-corrosive discharge; fissures at orifices (anus, nipples); eczema of folds with sticky oozing and rawness benefit from it [Clarke], [Boger]. Cracks of the fingers in cold weather ooze gluey serum; warm ointments and constitutional dosing hasten repair (Better warmth) [Clarke]. Cancerous and pre-cancerous ulcers (hard base, sluggish edges, ropy exudate) may be palliated, odour reduced, and comfort obtained—selection rests on the catarrhal-indurative signature rather than pathology alone [Clarke], [Boericke]. Acne rosacea with gastric derangement belongs here. Mini case: “Peri-anal fissures with ropy oozing—Hydrastis internally and warm bathing closed fissures” [Clinical], [Clarke].

Indications: chronic post-nasal catarrh with hawking of ropy yellow mucus; atonic dyspepsia with “goneness” and bitter morning taste; old-people’s bronchitis with tenacious expectoration; obstinate constipation with fissures/æmorrhoids; cervical erosion with thick, stringy leucorrhœa; pyorrhœa and aphthæ in debilitated subjects; indolent ulcers with viscid oozing; cachectic states adjacent to malignant disease (palliative) [Clarke], [Hering], [Boericke], [Boger], [Farrington]. Posology: Low to medium potencies are favoured for tissue tone—mother tincture (gtt. 1–5 in water), 2X–6X trits, or 6C once or twice daily in chronic mucosal atony; 12C–30C for general catarrhal patterns with marked modalities; higher potencies (200C) occasionally when the picture is striking across systems (clinical judgment) [Clarke], [Dewey], [Boger]. Repetition: steady, not frequent; reduce once hawking lessens, taste clears, stool softens without strain, and sleep deepens. Local adjuncts (never as substitutes): warm saline or mild calendula rinses for mouth; warm inhalations for larynx; sitz baths for fissures; gentle abdominal exercise; dietary simplification (avoid pastry/fats; use warm, simple meals) (explicit modality echo) [Clarke], [Farrington].
