• Bronchi and trachea. Violent cough with copious thin expectoration, retching/vomiting from cough, stitches in chest, dyspnoea in cold air or on exertion. See Chest/Respiration/Cough. [Hahnemann], [Hering], [Clarke]
• Nose and sinuses. Explosive sneezing; acrid morning coryza on rising, dripping in cold air; frontal pressure with fluent discharge. See Nose/Head. [Allen], [Clarke]
• Bladder and pelvic floor. Involuntary spurting of urine from cough, sneeze, or laughter; frequent urging with profuse pale urine. See Urinary. [Hering], [Boericke]
• Serous membranes. Hydrothorax/anasarca with orthopnoea; pleuro-pericardial irritation secondary to bronchial disease. See Chest/Heart/Generalities. [Hughes], [Clarke]
• Abdominal walls & diaphragm. Soreness of abdominal muscles from coughing/straining; tearing on motion. See Abdomen/Back. [Allen], [Hering]
• Kidneys. Reflex diuresis with respiratory relief; scant → profuse urine alternation guiding progress. See Urinary/Generalities. [Hughes], [Clarke]
• Stomach. Nausea and vomiting from cough, thirst for cold water; retching ends the paroxysm. See Stomach. [Hahnemann], [Allen]

• Warmth, warm room, warm clothing (nose, chest, bladder steadier). [Clarke], [Hering]
• After free expectoration—breathing eases once mucus is dislodged. [Hering], [Boger]
• After free urination—dyspnoea/fulness lighten when urine flows. [Hughes], [Clarke]
• Sitting up; leaning forward with arms supported during cough or dyspnoea. [Hering]
• Wrapping chest/abdomen; firm belt (supports sore muscles). [Allen]
• Slow, gentle motion in still, warm air. [Clarke]
• Sips of warm drinks between paroxysms. [Boericke]
• Open but mild air—cool drafts are bad, still mild air can soothe between attacks. [Clarke]
• Retching to vomit—paroxysm may end with vomiting and relief. [Hering]
• Afternoon compared with forenoon/morning. [Allen]

• Cold air, cold winds, damp raw weather (nose and chest flare). [Clarke], [Hering]
• Morning—on waking and on rising (sneezing/coryza/cough). [Allen], [Boericke]
• Exertion, walking fast, ascending—brings on dyspnoea and cough. [Hering], [Boger]
• Deep inspiration, laughing, talking—coughing fits; sneezing sets off cough. [Hahnemann], [Allen]
• Lying down (orthopnoea in effusions/anasarca); must sit up. [Clarke]
• Uncovering—especially head/chest; least cool air provokes paroxysm. [Boger]
• Suppression of perspiration or urine—breath tightens, oedema mounts. [Hughes]
• Dust, smoke, kitchen vapours—tracheal tickle; retching cough. [Clarke]
• Fruits/cold water during chill—shivers, cough aggravate. [Allen]
• Autumn–winter change; raw seaside winds (contrast with Nat-s.). [Tyler], [Clarke]

Irritable, anxious about the chest—fears suffocation when the cough mounts, snatches at the air; impatient if the room is cool or a door is opened. Hypochondriacal concern over the least chest-tickle; peevish on waking with morning coryza. Children are cross, cry before the cough and wet themselves during it; old people become anxious at night, must sit up and have the room warm. Mental dulness follows a long fit (spent from retching). The patient is unusually fastidious about clothing the chest, scolding those who let in cold air. Compared with Bry. (quiet, wants to be left alone, thirsts for cold), Ipec. (terror with suffocation but little expectoration), and Ant-t. (drowsy, cyanotic, rattling) the Scilla. subject is reactive, warm-seeking, and drenched with thin mucus, with that embarrassing urinary spurt on coughing that colours the whole demeanour. [Hahnemann], [Hering], [Clarke], [Boericke]

Bursting headache with each cough; frontal pressure with fluent coryza, worse on rising and in cold wind. The head feels cold externally yet hot within during the fit; stitches in temples when sneezing. Headache may be relieved after free expectoration or urination, echoing the remedy’s drainage logic. Compare Sang. (right-sided, burning flush), Nat-s. (damp-weather frontal with green catarrh), Kali-bi. (fixed root-of-nose ache with stringy mucus). [Allen], [Clarke], [Boger]

Smarting tears with cough and sneeze; lids water in cold air; conjunctivae redden during paroxysm. Photophobia with coryza outdoors; thick mucus threads from inner canthi in raw winds. [Allen], [Clarke]

Crackling in Eustachian tubes when swallowing; earache shoots with cough. Child starts from cough and puts hand to ear, then wets during the next spasm—an instructive ear–bladder–cough triad. [Hering], [Allen]

Explosive sneezing in the morning on rising; acrid, watery coryza running in streams in cold air, with soreness of alae nasi and upper lip. Smell diminished in raw weather; obstruction indoors grows fluent in the street (cold-air paradox: flow increases but cough and chest grow worse). Constant need to blow the nose; coryza alternates with chest tightness—when one is out, the other relents. Compare All-c. (acrid coryza with bland tears), Puls. (bland coryza, worse warm room), Nat-s. (green discharge, worse damp). [Hahnemann], [Allen], [Clarke]

Flushed during cough, then pale and anxious; sweat on forehead with dyspnoea. Children’s faces look worried before the paroxysm; old people have a puffy, pasty look in dropsical states. [Hering], [Clarke]

Mouth dry yet salivation increases once coughing begins; tenacious mucus in fauces that must be hawked. Great thirst, often for cold water, yet cold drinks may provoke a fresh cough. Tongue coated white; bitter taste in the morning. [Hahnemann], [Allen]

Teeth chatter with chills after coming out of warm bed to a cold room; jarring of cough sends pain to the molars. [Allen]

Tickling at suprasternal notch; scraping, rawness, and sudden urge to cough on drawing cold air. The larynx seems dry at first, then floods with thin mucus; voice rough in mornings, better after warm drinks and free hawking. [Hering], [Clarke], [Allen]

Nausea and vomiting from coughing; retches up phlegm and food; craves cold drinks between paroxysms. Epigastrium sore from straining; hiccough after a fit. Appetite poor in the morning (nose and throat streaming); more normal later. Compare Ipec. (constant nausea with little expectoration) and Drosera (paroxysmal cough with retching at night; less coryza). [Hahnemann], [Allen], [Clarke]

Abdominal walls sore and torn from coughing; stitches in hypochondria on deep breath or motion. Flatulence accumulates during catarrh; children press the belly during cough. A sense of weight/fulness accompanies dropsical states; better after urine flows. [Allen], [Hering], [Clarke]

Signature sphere. Urine spurts involuntarily with each cough, sneeze, or laugh, especially in women and in children—embarrassing, frequent, and confirmatory. Urging frequent; urine copious and pale when the chest frees, or scant when dyspnoea is tight. Burning at meatus after many paroxysms; dribbling on rising in the morning. Compare Caust. (incontinence with cough but far less coryza and more paralytic tone), Nat-s. (damp-asthma; no urinary spurting keynote), Staph. (post-partum stress incontinence without catarrh). [Hering], [Clarke], [Boericke], [Allen]

Soft, slimy stool with urging. Diarrhoea in children during teething or cold. Rectal tenesmus. Painful hemorrhoids with burning and itching. Stool difficult to pass even when soft.

Cough provokes prostatic and perineal pressure, then a spurt of urine; sexual desire low during catarrh. Orchialgia from abdominal wall strain rare but noted. [Allen], [Clarke]

Stress incontinence marked during cough/sneeze; worse after childbirth and in cold mornings; better warmth and pelvic support. Catarrhal menses—flow thin, increased by sneezing—confirm the discharge theme. Pregnant women cough to retching and wet themselves, pointing strongly to Scilla. Compare Sep. (pelvic laxity without such explosive catarrh), Puls. (mild, bland coryza). [Hering], [Clarke], [Boericke]

Breath short, quick, anxious in cold air; must breathe shallow to avoid a cough; sighing between paroxysms. Walking in a raw wind brings on a fit; warm room allows freer, deeper breaths after expectoration. [Hering], [Clarke]

Palpitation with dyspnoea on walking; pulse soft, compressible in dropsy; precordial oppression relieved when urine increases (diuretic axis). Pericardial irritation with pleuro-pericardial stitch during cough indicates Scilla. as a surface regulator, not a deep heart tonic. [Hughes], [Clarke], [Boger]

The field of action. Short, hacking or explosive cough ending in retching or vomiting, with copious thin expectoration and stitches in the intercostals; chest feels cold inside when breathing cold air. Dyspnoea on the least exertion; orthopnoea in hydrothorax—must sit up and keep warm. Rales coarse; mucus moves with difficulty until a gush comes and relieves. Stitches shoot through lower chest and to the scapulae on deep inspiration/cough. Compare Ant-t. (rattling with drowsy cyanosis), Senega (old folks, tough mucus but less urine-spurting), Phos. (burning chest, thirst for cold, more haemorrhagic), Bry. (dry, painful, must hold the chest, wants cold). [Hahnemann], [Hering], [Clarke], [Boger], [Farrington]

Dorsal and lumbar myalgia from coughing; must press with hands or bandage to cough. Stitches left lumbar region with sneeze; sacral aching in damp weather. [Allen], [Hering]

Cold hands and feet in morning coryza; oedema of ankles/legs in serous states; cramps in calves after a bout of coughing. Child stamps the feet before a sneeze then wets during cough. [Clarke], [Hughes]

Pale, puffy in dropsy; pit on pressure at ankles; sweat clammy during dyspnoea, less once urine flows. Urticarial flares after chill are occasional. [Clarke], [Hughes]

Restless from early-morning sneezing and cough; wakes to sneeze, then coughs till he retches and must sit up; drowsy after paroxysm. Old people sleep sitting, propped with pillows (orthopnoea). Children cry before the fit, then fall asleep exhausted and wet. Dreams of suffocation; wakes to open windows but is worse from the cold air. [Hering], [Allen], [Clarke]

Of choking, of being in a cold windy place; of running water and leaking taps (symbolic of the discharge theme). Dreams end with a start and a cough. [Allen], [Clarke]

Catarrhal fevers with chill on the least uncovering, heat in face during paroxysm, sweat with dyspnoea. Temperature not high; the burden is the mucus and breathlessness. As urine becomes freer the feverish oppression lightens. [Clarke], [Boericke]

Chill: steps into raw air → sneezing fit, then cough; gooseflesh with open window. Heat: flush of face and ears during coughing; hands hot, feet cold. Sweat: clammy during dyspnoea; later free urinary flow replaces sweat as relief path. [Clarke], [Allen], [Hughes]

Thirsty, often for cold water between paroxysms (yet cold drinks may provoke a fit). Aversion to fruit/cold fare in raw weather. Desire for warm soups; appetite poor mornings. [Hahnemann], [Allen]

A warm-seeking, surface-draining remedy whose relief comes by flow—of sputa and urine. Cold air, mornings, exertion, deep breath, sneezing, talking bring on cough; warmth, sitting up, supporting the chest/abdomen, free expectoration and urination relieve. The clinical trio—explosive morning coryza, paroxysmal cough with retching and stitches, and urinary spurting with the cough—is highly characteristic. In the aged and in children, dropsy ↔ catarrh ↔ bladder form a revolving door that Scilla. can regulate. [Hahnemann], [Hering], [Clarke], [Boericke], [Hughes], [Boger]

Paroxysmal, retching cough with much mucus

• Drosera. Night, whooping-like spasms to retching; less fluent coryza, more nocturnal; Scilla. is morning/raw-air and wet. [Clarke]
• Ipecacuanha. Constant nausea, little expectoration; chest full, suffocative; Scilla. has copious thin mucus and thirst. [Hering], [Farrington]
• Antimonium-tartaricum. Rattling, inability to raise, drowsy, cyanotic; Scilla. raises copiously and is reactive/warm-seeking. [Boger], [Clarke]
• Senega. Old folks, tough mucus, soreness of chest walls; less urine-spurting. [Farrington]
• Phosphorus. Tickling larynx, burning chest, haemorrhagic tendency, craves cold drinks; less urinary keynote. [Kent]

Coryza—explosive sneezing on rising

• Allium cepa. Acrid coryza, bland tears; < warm room; Scilla. < cold air; bladder involvement. [Clarke]
• Pulsatilla. Bland coryza, > cool open air; Scilla. is worse cold and more violent. [Clarke]
• Natrum-sulphuricum. Green catarrh in damp weather; asthmatic; lacks urinary spurting. [Boger]

Urinary incontinence from cough/sneeze

• Causticum. Stress-incontinence with paralytic tone; less catarrh; chilly but not so raw-air-sensitive in nose/chest. [Boericke]
• Sepia. Pelvic laxity, bearing-down; lacks explosive mucus picture. [Clarke]
• Staphysagria. Post-partum, emotion-provoked; not the catarrhal athlete. [Clarke]

Dropsy / Hydrothorax

• Apis. Puffy, stinging, thirstless, wants cold applications; Scilla. thirsty, coughy, urine-relieved. [Clarke]
• Digitalis. Cardiac dropsy with fear to move; slow weak pulse; Scilla. more broncho-serous with cough spurts. [Hughes]
• Arsenicum. Burning > heat, midnight aggravation, anxious restlessness, scant urine; Scilla. wants warmth but relief comes after urine and expectoration. [Kent]

Abdominal wall pain from coughing

• Bryonia. Must hold chest, dry painful cough, thirst for cold; Scilla. has thin mucus and urine spurts. [Clarke]
• Hyoscyamus. Urine loss from laughing/coughing (neurogenic); lacks chest/nose profile. [Boericke]

• Complementary: Kali-s. (later stage loose catarrh), Nat-s. (damp-weather sinus–bronchial), Caust. (pelvic floor after catarrh), Senega (aged bronchitis once urine-spurting subsides). [Boger], [Farrington], [Clarke]
• Follows well: Bry. (after dry pleuro-bronchitis turns loose), Ipec. (when nausea yields to productive cough), Apis (dropsy phase → catarrhal drainage). [Clarke], [Hughes]
• Precedes well: Ant-t. if rattling failure supervenes; Phos. where burning, haemoptysis appear. [Boger], [Kent]
• Antidotes: Camph./Nux-v. for gastric over-irritation from crude squill; general cold aggravations. [Hughes], [Clarke]
• Related (botany/action): All-c. (acrid coryza), Grindelia (asthma with expectoration difficulty—New World analogue). [Clarke], [Farrington]

• Morning explosive coryza + cough with retching + urine spurts (children, post-partum women, elderly): think Scilla. early; warm the room; coach pelvic floor support. [Hering], [Clarke], [Boericke]
• Senile bronchitis / hydrothorax: if urine increases as breath eases, Scilla. may lead, then Kali-s. / Senega tidy the later stage. [Hughes], [Farrington]
• Post-viral tracheitis with tickle at suprasternal notch, < cold air, fits on talking/laughing—Scilla. often aborts the cycle. [Clarke], [Boger]
• Pelvic-floor sequel after catarrh (women): finish with Caust. if stress incontinence persists once chest and nose are quiet. [Boericke], [Clarke]
• Mini-pearls

• • Child with volley sneezing on rising, then cough → vomit, beds wet with each fit → Scilla. 200C transformed mornings in two days. [Hering]
  • Elderly man, orthopnoea with ankle oedema; after Scilla., urine free, breath easier—then Kali-s. completed. [Hughes], [Farrington]
  • Young mother post-partum: stress incontinence on cough, raw-air coryza → Scilla. first, Caust. later for tone. [Clarke]

Mind

• Anxiety about suffocation during cough/dyspnoea; must have room warm. [Clarke], [Hering]
• Irritable, peevish on waking with morning coryza. [Allen]

Head / Nose

• Sneezing, morning, on rising—violent, repeated. [Allen], [Clarke]
• Coryza fluent in cold air; acrid watery discharge; upper lip sore. [Clarke]
• Headache bursting with cough; better after expectoration/urination. [Boger]

Throat / Larynx

• Tickling at suprasternal notch provoking cough (cold air). [Hering]

Chest / Cough / Respiration

• Cough paroxysmal, ending in retching/vomiting, with copious thin expectoration. [Hahnemann], [Hering]
• Urination, involuntary, during cough or sneeze. (also under Urinary) [Hering], [Boericke]
• Stitching in chest on deep inspiration and cough. [Clarke]
• Dyspnoea on exertion; orthopnoea; must sit up in warm room. [Clarke], [Boger]
• Chest feels cold internally when breathing cold air. [Allen]

Urinary

• Urine spurts with cough/laughter/sneeze (stress incontinence). Keynote. [Hering], [Boericke]
• Urine copious and pale after catarrhal paroxysm (relieves breathing). [Hughes], [Clarke]

Abdomen / Back

• Abdominal muscles sore/torn from coughing; must support with hands/band. [Allen]
• Stitches hypochondria from deep breath/cough. [Clarke]

Generalities

• Worse: cold air, morning, exertion, talking, deep inspiration. [Clarke], [Allen]
• Better: warmth, sitting up/leaning forward, after expectoration/urination. [Hering], [Boger]
• Dropsy with hydrothorax—relieved by increased urine. [Hughes], [Clarke]
