- Differentiation & Application
A marsh-dwelling buttercup of the Ranunculaceae with thin, hollow, acrid stems and bright yellow flowers. Like other Ranunculus species it abounds in ranunculin, which enzymatically yields the blistering lactone protoanemonin when the plant is crushed; this explains its vesicating, excoriating, and ulcerating effects on skin and mucosae and the intense burning–stinging pains so often recorded [Hughes], [Clarke]. The mother tincture is prepared from the fresh flowering plant, gathered before the acridity is lost on drying; local application of the juice is historically known to raise blisters, and internal overdosing has produced gastro-enteric irritation with salivation and diarrhoea [Hughes], [Allen]. [Toxicology]
Folk medicine employed the bruised plant as a counter-irritant or to “draw” (vesicate) obstinate structures and to cauterise warts, though such use readily caused ulceration and was abandoned by cautious physicians [Clarke], [Hughes]. Not used in modern pharmacology.
Symptoms come from Hahnemann’s provings and toxicologic observations augmented by Hering and Allen; clinical confirmations emphasise acrid, watery vesicles and excoriations, eczema behind ears and about mouth, paronychia/ulcerating warts at fingertips, raw burning in mouth–throat–larynx with hoarseness, and diarrhoea/tenesmus from intestinal irritation [Hahnemann], [Hering], [Allen], [Clarke]. [Proving] [Clinical] [Toxicology]
- Skin / integument: Chief sphere—watery vesicles, papulo-vesicular eczema with acrid serum that excoriates; rapid ulceration if scratched or poulticed. Classic seats: behind ears, about lips and chin, fingertips. See Skin, Face, Extremities. [Hering], [Clarke]
- Mouth / lips / oral mucosa: Burning aphthous spots, salivation, fissuring at angles; vesicles that burst and smart. See Mouth, Face. [Hahnemann], [Allen]
- Throat / larynx: Raw, burning fauces; hoarseness and tickle from laryngeal excoriation; cough follows talking or cold damp air. See Throat, Respiration. [Clarke], [Boericke]
- Gastro-intestinal mucosa: Gastric burning, nausea, and acrid diarrhoea with tenesmus in toxicology; stools excoriate. See Stomach, Rectum. [Hughes], [Allen]
- Peri-ungual tissues / nails: Paronychia, painful ulcerating hang-nails, and soft, flat warts around nails; touch intolerable. See Extremities, Skin. [Hering], [Clarke]
- Eyes / lids: Excoriating lachrymation; lids raw at margins when face eruption is active. See Eyes. [Allen], [Clarke]
- Respiratory wall / chest edges: Stitching, costal pains and pleurodynia appear in the Ranunculus group; with Ran-scel. they accompany superficial vesication rather than deep intercostal neuralgia (Ran-b.). See Chest, Back. [Farrington], [Boger]
- Weather / environment reactivity: Marked aggravation from damp cold, marshy air, and wetting, with soreness and blistering from friction. See Generalities, Skin. [Clarke], [Boericke]
- Cool or cold applications on burning vesicles (smarting abates) [Clarke].
- Dry warmth and a dry room when the complaint is from damp exposure [Hering].
- Gentle uncovering of excoriated parts; avoiding woollens and friction [Clinical].
- Rest and quiet, avoiding rub or pressure on paronychia or costal stitches [Boger].
- Bland ointment barrier (simple oil/vaseline) to shield acrid discharge (adjunctive) [Clarke].
- Sipping cool water for burning in mouth and throat [Allen].
- After stool when diarrhoeal tenesmus has emptied (burning lessens) [Hughes].
- Fair weather / dry air, change to upper, non-marshy dwellings [Clarke].
- Damp cold, rainy weather, fog, marshy or riverside air [Clarke], [Boericke].
- Touch, rubbing, pressure, and tight clothing—vesicles break, ulcers spread [Hering].
- Washing and soaking of hands (laundry work, fishermen) → paronychia [Clarke].
- Changes of temperature, chill after warmth; evening exposure [Hughes].
- Perspiring then chilling; under wet coats, boots; long wetting of feet [Boericke].
- Speaking, singing, or cold air to larynx—hoarseness/cough rekindled [Clarke].
- Acid, salty, or very hot foods on oral vesicles (smarting) [Allen].
- Scratching—itch turns to burning; excoriation rapidly ulcerates [Hering].
- Friction at elastic lines (neck, wrists) and behind ears in children [Clarke].
- Night for burning and tingling of eruptions; dawn for stool urging [Allen].
- Sea-mist / river fog and damp cellars (relapse trigger) [Clarke].
- Old scars and callosities (irritated, redden, may vesicate) [Boger].
Watery vesicles with acrid discharge / excoriation
- Rhus-t. — Intensely itchy vesicles > hot water; Ran-scel. burns after scratching, worse damp, seeks dry air [Farrington], [Boericke].
- Croton-t. — Vesiculo-pustular eruption with copious, yellowish oozing along hair; Ran-scel. has small watery blisters and corrosive edge [Clarke].
- Graph. — Thick honey crusts, fissures, behind-ear eruptions but less watery and less acrid than Ran-scel. [Clarke].
- Euphorb. — Violent burning and deep ulcerations; Ran-scel. more surface and marsh-damp aetiology [Farrington].
- Canth. — Great vesication with urinary tenesmus; Ran-scel. centres on skin/mucosa without urinary keynote [Allen].
Peri-ungual / paronychia / warts
- Hepar-s. — Suppurative, throbbing paronychia > warmth; Ran-scel. watery vesication → ulcer worse wetting [Hering].
- Ant-c. — Soft warts, crusty impetigo; Ran-scel. has acrid weeping and damp trigger [Clarke].
- Thuja — Multiple sycotic warts, pedunculated; Ran-scel. softer, flat peri-ungual warts with soreness [Boericke].
Mouth / lip excoriation
- Merc. — Profuse saliva, offensive mouth with ulceration < night; Ran-scel. saliva excoriates but general Merc. cachexia is absent [Allen].
- Nat-m. — Angular stomatitis with dryness; Ran-scel. has watery vesicles and burning [Clarke].
Hoarseness / raw larynx from damp air
- Dulc. — Catarrh from damp cold; more mucous flow, less acrid surface burning than Ran-scel. [Farrington].
- Rumex — Tickle-cough < cold air to larynx; Ran-scel. adds vesicating skin and mouth picture [Boger].
Chest wall stitches / pleurodynia
- Ran-b. — Deeper intercostal neuralgia, worse motion/changes of weather, often “sailor’s pleurodynia” [Farrington]; Ran-scel. has shallower costal soreness with cutaneous eruptions.
- Complementary: Dulc. (damp-cold catarrh) when mucous surfaces predominate and Ran-scel. treats the acrid skin edges [Farrington].
- Complementary: Graph.—after Ran-scel. dries the watery excoriation, Graph. closes residual cracks behind ears [Clarke].
- Follows well: Rhus-t. in vesicular states that relapse in foggy weather but dislike hot bathing [Boericke].
- Follows well: Hepar-s. where paronychia has passed the threatening-suppurative phase and watery excoriation remains [Hering].
- Precedes well: Sulph. constitutionally in chronic damp-dwelling families with recurring weeping eczema [Kent].
- Related / compare: Euphorb., Canth., Croton-t., Ant-c., Thuja, Dulc., Ran-b. for the fields above [Clarke], [Farrington].
- Antidotes (local): Cool applications; avoid poultices which hasten ulceration—classical practical caution [Clarke].
Ranunculus sceleratus is the marsh buttercup made clinical: a remedy for those who live in dampness—river workers, laundresses, anglers, children with sweaty heads—and whose skin responds with small, watery blisters that burn after scratching and quickly excoriate. Its chemistry (protoanemonin) maps straight to the bedside: crush the plant and you get vesication; let the eruption be rubbed or poulticed and you get ulceration [Hughes], [Clarke]. The distribution tells the tale—behind ears, about lips and chin (with saliva that excoriates), fingertips and nail-folds (wet work → paronychia), and along elastic/friction lines. The modalities are cardinal: worse damp cold, fog, wet clothes, washing/soaking, friction, and scratching; better brief cooling and then keeping absolutely dry, with loose, non-woollen coverings. In the upper air passages the same edge appears: raw, burning fauces and larynx, hoarseness in fog, cough on speaking; a few cool sips soothe, but dry rooms ultimately cure. Compared to its cousin Ranunculus bulbosus, which gives deep intercostal neuralgia and shingles-like pains, Ran-scel. dwells at the surface, the mucosa–skin margin, with acrid moisture and rapid excoriation. Set it against Rhus-t. (itchy vesicles > hot water), Graphites (thick, honey crusts rather than watery blisters), Croton tiglium (profuse streaming along hair), and Cantharis (blister + urinary tenesmus). Once you hear “it weeps water that burns,” “damp makes it worse,” “washing and wet hands bring it on,” and observe that cooling gives a minute’s ease but dryness heals, you have Ranunculus sceleratus in your grasp. [Hering], [Clarke], [Farrington], [Boericke], [Allen]
- Behind-ear eczema in damp-dwelling children—watery weeping that excoriates, worse washing, better dry air: Ran-scel. 6x–30C once or twice daily for a few days; avoid poultices; keep dry with simple barrier salve [Clarke], [Hering].
- Paronychia / hang-nails from wet work—tense, vesicating margins that ulcerate on soaking: Ran-scel. 6x t.i.d. for several days, then space; keep hands dry, cotton gloves at night [Hering], [Clarke].
- Perioral vesicles with salivation that excoriates—salt/hot foods smart; cool sips soothe: Ran-scel. 30C at onset; avoid acids; dry, bland regimen [Allen].
- Hoarseness and laryngeal rawness from fog with superficial chest wall stitches: Ran-scel. 30C prn; move to dry room, silence for a few hours [Clarke], [Boericke].
