Mind

The mental picture is secondary to skin torment: irritability, fretfulness, and a kind of despair that peaks at night when itching forbids rest—he dreads the approach of bedtime, knowing he will pace or tear at the skin; this squares with the general night aggravation and the sleep section’s broken first sleep [Hering], [Boericke]. A nervous tension accumulates under the curfew of itch: noises are hateful, clothes are intolerable, and the patient becomes fastidious about seams and wool, reflecting the friction aggravation noted under Modalities [Clarke]. The aged grow hypochondriacal from long-standing useless treatment; relief by cool sponging restores their humour, echoing the cool-open-air amelioration found throughout [Clarke]. In pregnancy, the expectant mother becomes anxious, ashamed by genital itching; she seeks the cool and avoids warm baths after learning their mischief—objects that match the Female and Skin modalities [Phatak]. Sleeplessness engenders impatience and tears; yet there is no profound melancholia, only a reactive mind tethered to a psoric skin [Kent]. After relief (cooling, a dose taken), mood rises disproportionately, proving the mind was bound to the skin torment [Clarke]. Children are peevish at night, rub the anus and vulva, then fall asleep exhausted; after a cool wipe and airing they smile, the behaviour reinforcing Dolichos’s simple law: heat betrays, cool relieves [Hering].

Sleep

Destroyed by itching, especially first sleep; he dashes from bed to the window, rubs furiously, gets a minute’s ease that turns to burning; he then cools, dozes, and repeats until morning—this seesaw exactly mirrors the Modalities [Hering], [Boericke]. The aged mutter and toss until a cool cloth breaks the cycle; pregnant women prowl rooms at night for a draft—behavioural pathognomonic for Dolichos [Clarke]. Dreams of insects crawling, of heat and stifling rooms; dreams cease when nights cool and itch is mastered (mind mirrors skin) [Tyler]. Morning finds the sufferer unrefreshed, irritable; yet a single decent night after a dose raises spirits and strength [Clarke].

Dreams

Creeping, ants, hair on the skin; of undressing to cool; of searching for a breeze—dreams that directly symbolise the day’s itch [Tyler]. With hepatic cases, dreams of yellow rooms, dirty water; after improvement dreams are neutral and sleep continuous [Clarke]. Children cry out, scratch in sleep, then dream of being washed; the dream predicts the correct palliative—cool water [Hering].

Generalities

Dolichos centres on psoric itching—often without visible eruption—that is worse at night, worse warmth of bed/hot bathing/wool and friction, and better from cool applications, cool open air, uncovering, and tepid washing [Hering], [Allen], [Clarke]. Borders (anus, vulva, scrotum, eyelids, canthi) and folds are favourite sites; scratching is treacherous—a flash of relief then burning and renewed itch. A second axis is hepatic: jaundice, dark urine, clay stools, constipation, and an itch “out of proportion,” often worse with dietary fats and relieved as bowels move [Hughes], [Clarke]. A third, smaller axis is neuralgic—right-sided facial neuralgia at night, sometimes exchanging places with the itch. The aged and pregnant are signature populations. When a case shows no rash, sleeplessness from itching, night/heat aggravation, cool amelioration, and hepatic or anal/genital border themes, Dolichos rises to the top. Cure is evident when first sleep holds, the need to uncover abates, bowels regulate, and the skin can bear warmth without treachery.

Fever

No specific febrile curve; skin may feel hot in bed while the patient begs for cool air (surface–subjective split) [Clarke]. Jaundiced subjects may have slight evening elevations; the key remains itch out of proportion to cutaneous findings [Hughes]. With sleep restored, subjective heat recedes; fever belongs more to the antecedent liver status than to the remedy’s core [Clarke].

Chill Heat Sweat

Heat (bed, bath, room) aggravates itching; cool and moving air ameliorate—an unbroken law through the case [Hering], [Clarke]. Sweat in folds stings and excoriates already scratched surfaces; keeping the skin cool and dry is part of the cure [Clarke]. No pronounced chill apart from the desire to uncover hot parts even on a cool night. After a hot bath there is often a rebound itching paroxysm, instructive for prescribing [Hering].

Head

Head is hot to the hand while the patient feels “prickles” in the scalp; he rummages the hair for a rash that is not there—a pure Dolichos paradox of itching without eruption [Allen]. Warm rooms intensify scalp itch; standing by an open window soothes, as in Generalities [Clarke]. A tight band feeling accompanies sleepless nights; in bilious subjects the temples throb after fatty supper, and scalp prickles return as the liver protests (liver–skin axis) [Hughes]. The right-sided facial attack is peculiar: tic-like neuralgia of the right cheek, worse at night, worse motion and jar, sometimes alternating with or following days of skin itch—this shifting of the complaint from surface to nerve is typical of Dolichos [Clarke], [Allen]. Head covering of wool aggravates scalp itch; linen is borne [Clarke]. As sleep returns, head pressure lifts with the itch’s retreat—functional more than structural [Hering].

Eyes

Lids and canthi itch and burn without conjunctival disease; rubbing the angles brings brief peace then rawness—a microcosm of the scratching paradox [Allen]. Warm rooms redden the rims; open air relieves (thermal split repeats) [Clarke]. No profound photophobia or lacrimation; the eye is a border telling the same story as nostrils, lips and anus [Hering]. Eyelash line prickles at night in the warmth of bed; cool compress quells it [Boericke]. In jaundice cases, sclerae subicteric with itch of lids—the liver announces itself at the margin [Hughes]. Recovery tracks with the skin elsewhere: canthi cease to sting first at evening cool [Clarke].

Ears

Itching of the conchal rim and meatus; the patient rubs with a towel, later complaining of burning; warm bath provokes relapse (worse hot bathing) [Hering]. Ears feel too hot in bed; uncovering or cool air gives ease (better cool, worse heat) [Clarke]. No deep otalgia or discharge; the symptom is border pruritus in a small circle [Allen]. Sounds annoy at night when the itch is high-pitched in the mind; quiet helps sleep [Boericke]. Lobes flush with scratching, then cool with air; a visible rehearsal of Dolichos’s physiology [Clarke].

Nose

Nostrils and alæ itch; patient rubs until sore; sneezing in warm, close rooms; cool air abates the tickle—another border echo [Allen]. Tip of nose feels pricking ants at night; no coryza; wiping with a cool cloth slows the urge to scratch [Clarke]. With pruritus ani cases in children there is nose-picking at night, pointing to the worm background in a subset (compare Cina) [Hering]. Odours of hot kitchens are oppressive, and the nose smarting is worse with steam (heat aggravation) [Clarke].

Face

Right-sided neuralgia of cheek and jaw at night, boring–shooting pains, worse motion/jar, sometimes tied to constipation; warmth aggravates; relief comes with cool applications or after bowels act—Dolichos’s nervous–abdominal linkage [Clarke], [Allen]. Lips and angles may itch without eruption, chapped from rubbing; hot soups feed the smart (food-heat aggravation) [Clarke]. Beard area prickles after warm shaving water; cool shaving lessens it—behaviour tallies with the thermal law [Clinical—Clarke]. Colour waxy in old hepatic pruritus with clay stools; scratching marks face and ears [Hughes].

Mouth

Itching of palate and gums; the patient rubs the palate with the tongue until raw; sweet/hot things aggravate the tingle (food modality) [Allen], [Clarke]. Teeth feel elongated during nocturnal neuralgia; jaw motion increases facial pain; warmth of bed aggravates, correlating with the skin’s night increase [Clarke]. Saliva normal; taste bitter in biliary subjects (hepatic imprint) [Hughes]. After cool water rinses the palate quiets; hot drinks reignite the itch (thermal split) [Hering].

Teeth

Dentition states show itching gums rather than outright toothache; children rub gums and scratch ears at night; constipation coincides (stools hard, knotty), and sleep is broken—an infantile Dolichos triad [Hering]. Adults with right facial neuralgia complain of “toothache” worse at night, actually a neuralgia mapped to Dolichos, better local cool [Clarke]. No carious pathology is specific; pains track the neuralgic and psoric axes rather than pulp disease [Allen].

Throat

Fauces and palate itch, provoking hawking and tongue-rubbing; warmth of drinks aggravates, cool sips soothe (thermal law repeats) [Allen]. No diphtheritic or membranous signature; the symptom is superficial, a border itch in the throat as at nares and anus [Clarke]. Dryness subjective; mucus ordinary; the suffering is from the tingle that forbids rest. In hepatic pruritus, the throat feels hot after fatty food though temperature remains normal (reflex) [Hughes].

Stomach

After rich, greasy meals or sweets the itch intensifies and the right hypochondrium feels heavy; belching pallid, appetite capricious—a hepatic dyspepsia that sets the skin alight later in bed [Clarke], [Hughes]. Nausea is uncommon; rather a loathing from the association “food = later itch.” Warm drinks at night are unwise; tepid or cool liquids do not flare the palate (see Mouth/Throat). The dyspepsia is chiefly biliary, not gastric, and the remedy’s action attends the liver–skin conduit [Hughes]. When bowels are opened, the evening itch sometimes lessens; constipation is thus an aggravating accessory [Allen].

Abdomen

Liver region tender; jaundice in some cases; stools pale or delayed; urine darker; the itching is “out of all proportion” to visible eruption, a classic cholestatic pruritus profile that points to Dolichos when cool amelioration and night aggravation are pronounced [Hughes], [Clarke]. Flatulence mild; cramping rare; the abdomen’s message is hepatic. Pregnant women complain of tight skin itch across abdomen and flanks, worse heat, better cool sponging—gestational Dolichos [Phatak]. Scratching raises small wheals then burning; leaving it alone is impossible; the signature is psoric and superficial [Hering].

Rectum

Pruritus ani violent at night; children and the aged rub the part in sleep; ascarides suspected; scratching excoriates; washing with tepid or cool water relieves, whereas hot bathing aggravates (precise modality) [Hering], [Clarke]. Constipation obstinate: hard, dry, knotty stools; anus burns if scratched before stool; bleeding slight [Allen]. Itching may persist after stool when piles or fissures are present, but the Dolichos stamp is the itch without eruption and night aggravation with relief by cooling [Boericke]. A case may swing between anal and vulvar itch across weeks—border migration in the same patient points to Dolichos [Clarke].

Urinary

Dark urine with hepatic itch; nocturnal frequency in the aged affects sleep further; urination itself does not itch, but urine excoriates raw anal/genital borders scratched previously (secondary) [Hughes], [Clarke]. No primary cystitis signature. Chill of night chamber aggravates overall itch unless the air is cool but moving, again a nuance the patient learns [Clarke].

Food

Sweat brings stinging on excoriated borders; in the aged, night-sweat accompanies fretful scratching; with the case improved, sweat no longer burns and nights quieten [Clarke]. Exercise in heat restarts the cycle; cool, gentle ambulation in evening air helps [Boericke].

A tropical legume of the Fabaceae whose pod-hairs contain intensely pruritogenic principles (historically “mucunain”; modern chemistry recognises proteolytic/serotonergic constituents) that provoke violent itching and wheal-like irritation even without visible eruption—an external action that faithfully prefigures the remedy’s keynote “itching without eruption” and the cholestatic/senile pruritus sphere [Toxicology—Hughes], [Allen], [Clarke]. In pharmacy, the fresh irritant hairs or seeds are tinctured and potentised; pathogenesy arises from provings compiled by Allen and Hering and abundant clinical confirmations in nocturnal pruritus, pruritus vulvæ/ani, hepatic itch with jaundice, and obstinate constipation with maddening cutaneous itch and insomnia [Hering], [Allen], [Clarke], [Boericke]. Cowhage hairs were once used crudely as a mechanical anthelmintic (vermifuge) by irritating intestinal parasites—this anthelmintic history helps explain the anal and genital border-itching recorded clinically [Hughes], [Clarke].

Seeds and hairs were employed in traditional medicine as anthelmintic (mechanical expulsion of ascarides), as a folk antipruritic/vesicant (counter-irritant), and the plant has been used agriculturally as a cover crop; ethnobotanical notes describe topical itching trials as a diagnostic of nerve endings’ integrity [Hughes], [Clarke].

Fragmentary provings and clinical pathogenesy were gathered by Hering and Allen; Clarke consolidated the picture: violent itching, worse at night and in bed, often with no rash; constipation; right-sided facial neuralgia; hepatic derangement with jaundice and pruritus; pruritus vulvæ/ani [Proving/Clinical—Hering], [Allen], [Clarke]. Early practitioners repeatedly confirmed senile pruritus, pregnancy itch, and anal/genital itching that drove to sleeplessness, together with constipation and a peculiar right-sided facial neuralgia intensifying at night [Boericke], [Boger], [Phatak].

• Inimical: None specifically recorded in classical sources [Clarke], [Boericke].

Dolichos is psora in its starkest surface form: maddening itching with little or no eruption, ruling the night, fanned by heat, subdued by cool air and cool ablutions. The kingdom signature—cowhage hairs that provoke itching “out of all proportion”—translates precisely into the homœopathic portrait: the patient searches for a rash and finds none, yet the urge to scratch is irresistible; scratching is treacherous—giving a flash of satisfaction and then burning and renewed itch. The modalities are crystalline: worse at night, worse warmth of bed and hot bathing, worse wool/friction, better cool sponging, open air, uncovering, and light linen. These are not mere comforts; they are diagnostic laws that must reappear in the case’s behaviour (standing by the open window, flinging off covers, fleeing hot baths). The organ affinities triangulate the selection: (1) Skin borders and folds—anus, vulva, scrotum, canthi—become theatres of torment; (2) Liver—cholestatic pruritus with jaundice, dark urine, clay stools, and constipation, where the itch exceeds the rash; (3) Nerves—a right-sided facial neuralgia that shares the same nocturnal, heat-worse signature or alternates with the itch. The age and state colouring is strong: senile skin—dry, thin, reactive; pregnancy and lactation—hormone and skin-stretch contributions; both amplify Dolichos’s law.

Miasmatically the remedy is psoric, with sycotic recurrence and slight syphilitic excoriation after furious scratching. The pace is chronic–paroxysmal: quiet days, then nights of tyranny; the reactivity is peripheral (sensory endings/c-fibres) rather than exudative—hence the absence of eruption so characteristic. Core polarities sharpen the decision: cool ↔ heat, night ↔ day, uncovered ↔ covered, border surfaces ↔ deep tissue, itch primary ↔ wheal secondary. Micro-comparisons clinch selection: Rhus is better hot and shows vesicles; Urtica gives wheals first; Sulphur is also worse warmth of bed but is dirtier, often eruptive, and not so cool-seeking; Arsenicum burns and seeks heat, the thermal opposite. In hepatic cases, Chelidonium paints the liver; Dolichos paints the skin’s cry from the liver’s error. Clinically, cure demands obedience to the law: ventilate, lighten coverings, avoid hot baths, choose tepid/cool washing, swap wool for linen, and calm the diet (avoid fats/sweets). A right prescription shows itself immediately in sleep returned—the sufferer dozes through first sleep without a leap to scratch; palms/soles no longer fly from bedclothes; the anal/vulvar borders bear the contact of linen; jaundice lightens with bowel regulation. Dolichos is thus the quintessential remedy when the surface shouts, the night betrays, the heat torments, and the eye cannot find the rash that torments.

Senile pruritus: aged, itching without eruption, worse warmth of bed/hot bath, better cool air/sponging; sleep destroyed—Dolichos often succeeds where mere ointments fail [Clarke], [Boericke].
• Pregnancy/pruritus vulvæ: nightly torment of vulva and abdomen, modalities as above; tepid sitz and light linen while dosing; avoid hot bathing [Phatak], [Clarke].
• Hepatic itch with jaundice, dark urine, clay stools; itch disproportionate to skin findings; regulate diet (avoid fats), bowels, and ventilate bedroom; Dolichos as the similimum [Hughes], [Clarke].
• Pruritus ani (worms/ascarides): nocturnal scratching, no rash; cool ablutions relieve; consider Teucr./Cina intercurrently for worms; return to Dolichos for residual heat-worse psora [Hering], [Clarke].
• Right facial neuralgia, worse night, heat intolerable, alternating with days of itch; Dolichos covers this nervous extension [Clarke], [Allen].
• Potency: 6C–30C commonly; repeat in acute night paroxysms until the itch–sleep curve turns, then pause; chronic hepatic/senile cases often need 30C (weekly) or 200C at intervals when picture is pure [Boericke], [Phatak].
• Nursing adjuncts are part of the prescription: cool air, tepid/cool washing, light linen, avoid hot baths, plain diet, bowel regulation—enact the remedy’s modalities for lasting success [Clarke], [Hughes].
