Zincum arsenicosum
Substance Background
A prepared salt of zinc with arsenious acid (arsenite). In pharmacy it is triturated from a pure salt to prepare potencies. Arsenites are protoplasmic poisons with marked neuro-vascular and trophic effects; zinc, as a nerve-associated metal in homeopathy, furnishes a sphere of spinal and peripheral nerve irritation with restlessness, trembling, and exhaustion. The composite picture in the literature blends Zincum’s spinal–cerebral irritability and Arsenicum’s burning pains, anxiety, and nocturnal aggravation, yielding a remedy for progressive neuritis, restless legs, ataxic and paretic states, anginoid pains, and chronic kidney/skin sequelae after suppression [Hughes], [Allen], [Clarke], [Boericke], [Boger], [Phatak]. [Toxicology] [Clinical]
Proving Information
Symptoms derive from smaller provings, toxicology of arsenites, and clinical confirmations. Recurrent threads: fidgety, incessant movement of the feet/legs, paresthesiae and burning along nerves, tremors, weakness after mental strain, insomnia after midnight, restlessness with anxiety, palpitations/anginoid constriction, albuminous or scanty urine, eczema/psoriasis suppressed → nervous phenomena [Allen], [Clarke], [Boericke], [Boger], [Phatak], [Tyler]. [Proving] [Toxicology] [Clinical]
Remedy Essence
Zinc-ar. is the overworked, over-wired nerves remedy with an Arsenicum flame running through them. The patient is restless in the limbs—especially the feet, which must keep moving—yet mentally exhausted, made worse by study and late hours. Pain quality is burning, crawling, tingling, running along nerves that behave like hot wires; these pains worsen after midnight and are soothed by local warmth and gentle motion. The chest and heart join the drama with anginoid tightness and anxious palpitations at night; the kidneys answer with scanty, albuminous urine; the skin tells its secret with burning eczema/psoriasis, often suppressed shortly before the nervous and cardiac aggravations mounted. This suppression–nervous aggravation axis is pivotal: when the skin acts again, the head clears, the spine quiets, and sleep returns. The remedy’s polarities are diagnostic: warmth to the nerves, fresh air to the face; gentle motion >, mental effort <; wine/stimulants <, small sips and light food >; after midnight <, early rest >. Place it between Zincum met. and Arsenicum: it has Zinc’s fidgety feet and spinal irritability, and Ars.’s burning and 1–3 a.m. anxiety; distinguish it from Cupr-ars. (tetanus-like cramp/collapse), Kali-ars. (asthma/skin), and Pic-ac. (brain-fag without burning neuralgia). In practice, marry the prescription to regimen: cut stimulants, schedule mental work, guard early sleep, apply local warmth to neuralgic tracts while airing the room, and never briskly suppress the skin—improvement then follows the remedy’s map, from quieter legs to cooler chest to steadier sleep.

Affinity
- Peripheral nerves (primary): Burning, tingling, crawling and shooting pains coursing along nerves with restlessness of limbs and tremor; night aggravation and warmth > the burning, combining Arsenicum’s pain-quality with Zincum’s fidgetiness. Cross-ref. Extremities, Sleep, Generalities. [Clarke], [Boericke], [Phatak]
- Spinal cord / motor pathways: Irritable weakness—twitchings, startings, ataxic gait, easy fatigue of legs; worse after long mental work or suppressed eruptions; better by gentle motion. Cross-ref. Back, Extremities, Mind. [Hughes], [Boger], [Allen]
- Heart and chest (anginoid): Constriction, stitching precordial pains with anxious restlessness and burning; attacks at night; compares with Arsenicum and Kali-ars. Cross-ref. Heart, Respiration. [Clarke], [Boericke]
- Kidney/urinary: Irritation with albuminuria, scanty, high-coloured urine; burning urethral sensations; fatigue of kidneys in chronic toxemia. Cross-ref. Urinary, Generalities. [Allen], [Boericke]
- Skin and trophic: Eczema/psoriasis with burning itching, worse warm bed; suppression precedes nervous or cardiac aggravations. Cross-ref. Skin, Mind, Generalities. [Clarke], [Phatak]
- Cerebro-mental fatigue: Head pressure, confusion, aggravation from study, relief by discharge/eruption returning; sensitive to wine and stimulants. Cross-ref. Mind, Head, Food & Drink. [Hughes], [Boger]
- Gastro-intestinal mucosa: Arsenical burning in stomach with Zinc-type aggravation from mental strain; small sips tolerated. Cross-ref. Stomach, Fever. [Allen], [Clarke]
- Respiratory nerves: Asthmatic oppression after midnight with anxiety and desire for air; neurogenic dyspnoea. Cross-ref. Respiration, Sleep. [Boericke]
- Female pelvic nerves: Neuralgic dysmenorrhoea with burning and restless legs; menses irregular after skin suppression. Cross-ref. Female, Skin. [Clarke], [Phatak]
Better For
- Gentle, continuous motion of the limbs (fidgeting the feet eases crawling/burning) [Boger], [Boericke]
- Warmth to neuralgic parts (hot applications or warm clothing calm burning pains) [Clarke], [Phatak]
- Rest after mental work, lying quietly with limbs supported [Allen], [Tyler]
- Return of eruptions or discharges (head and spinal symptoms lessen) [Clarke], [Boger]
- Small, frequent sips of water during gastric burning [Allen]
- Open cool air for oppressive anxiety (without chilling the part) [Boericke]
- Pressure or bandaging over trembling muscles (steadies them) [Clinical], [Boger]
- Sleep before midnight (if obtained) often refreshes more than late sleep [Tyler]
Worse For
- Night, especially after midnight (1–3 a.m.)—anxiety, burning, palpitations, restless legs [Clarke], [Boericke]
- Mental exertion, study, prolonged concentration—head pressure, spinal irritability, tremor [Hughes], [Boger]
- Suppressed eruptions or discharges—nervous/cardiac aggravations ensue [Clarke], [Allen]
- Wine, alcohol, stimulants—increase nervous excitability and palpitations [Boger], [Tyler]
- Cold draughts on nerves—neuralgia rekindles, cramps return [Phatak], [Clarke]
- Exertion and fatigue—ataxy and trembling worse on rising/walking [Boericke]
- Warm bed for itching skin, yet paradoxically burning pains may prefer warmth [Clarke], [Phatak]
- Touch/pressure over hyperaesthetic nerves, sudden jar [Allen]
- During menses or after loss of fluids, weakness and neural irritability increase [Clarke]
Symptomatology
Mind
The mental state shows irritable weakness: quick exhaustion from thinking, over-sensitivity to noise and conversation, and a constant sense of being over-wired yet under-powered [Hughes], [Clarke]. Restlessness is coloured by Zincum—incessant movement of the feet under the table or in bed—and by Arsenicum—anxious searching for relief, especially after midnight [Boericke], [Phatak]. Mental exertion aggravates spinal and head symptoms until the patient must stop work, and there is relief when a suppressed eruption or discharge returns, directly echoing the modality already noted [Clarke], [Boger]. The temper is snappish from nerve pain; fear of heart trouble attends palpitations and chest constriction at night. Suspiciousness and worry about health rise with paresthesiae; the patient carefully arranges warmth to painful nerves but craves cool air for the general oppression, a polarity consistent with the salt’s dual parentage. Compared with Zincum metallicum, Zinc-ar. is more burning, anxious, and nocturnal; compared with Arsenicum album, it is more spinal and fidgety, less despairing, and more driven by overwork and suppression than by fear alone [Clarke], [Boericke].
Head
Headaches are pressure-like and constrictive, seated in the occiput or vertex, aggravated by study and noise, and relieved by rest or by the return of a cutaneous eruption [Hughes], [Clarke]. There is a sensation as if the brain were hot and tired rather than congested; the scalp is tender along nerve lines. Vertigo attends sudden rising and after late hours; trembling accompanies attempts to concentrate. The head feels better in open cool air but the neck demands warmth; this divergence highlights the combined Arsenicum–Zincum modality. Micro-comparison: Picric acid shares the brain-fag and occipital heaviness from overwork, yet lacks the fidgety feet and burning neuralgia; Kali-phos. calms mental fatigue without the nocturnal burning anxiety seen here [Boger], [Tyler].
