Arsenicum iodatum
Made from arsenic triiodide — the marriage of the great poison with the thyroid element, and the classical remedy of restless exhaustion with burning discharges.
The whole picture, in one breath
Think of Arsenicum album set on fire: the same anxious restlessness and prostration, but with intense heat, burning discharges, dusky redness and wandering pains — worse from warmth of any kind, better in open air. Arsenicum's anxiety plus iodine's heat: that is Arsenicum iodatum.
The substance, in plain words
Arsenic triiodide joins the era's most famous poison to its most famous antiseptic element — iodine tinctured the wounds of every army. The proving blended both parents: Arsenicum's restlessness and Iodine's burning heat and glandular action.
The traditional picture Classical sources
The inner state
- Restless anxiety like Arsenicum. Fear, worry, prostration — the family inheritance — but hotter, with less chilliness than Arsenicum album.
- Irritability from heat. Cross, exhausted, worse as the warmth of rooms and bed builds.
- Despair in prostration. The books pair it with low, lingering states where vitality keeps sinking.
The body
- Heat and burning discharges. The keynote: watery, burning, acrid discharges with intense heat — unlike Ars-alb's chill.
- Worse from warmth. Aggravated by heat, warm rooms, warm clothing; relieved by open air — the decisive difference from Ars-alb.
- Intermittent and hectic fevers. The old books used it in the fevers that came and went with sweat and prostration.
- Hay fever and glandular swellings. From the iodine parent: swollen glands, catarrhs of the air, seasonal sniffles.
- Wandering pains. Pains that shift joint to joint with the restlessness.
- Dusky redness and exfoliation. Skin redness with peeling — the books' use in fiery skin states.
Modalities (worse and better factors)

Where it acts (organ affinities)
Glands and lymphatics, skin (burning, exfoliating), respiratory mucosa, general vitality.
Where the classical picture comes from
The compound's proving split the difference between its parents — Arsenicum's sinking restlessness and Iodine's burning glandular heat. Clinically it attached to the hot, restless, protracted states where plain Arsenicum was too chilly.
The substance in real medicine Pharmacology
What this section is: the pharmacology and toxicology of the source substance. It is not clinical evidence that a homeopathic preparation of it treats any condition. What controlled trials do and do not show is set out on the Evidence page.
Both parents of this remedy are real chemistry: arsenic trioxide as the leukemia drug (see Arsenicum album), and iodine as one of medicine's great antiseptics and thyroid essentials. The compound itself belongs to pharmaceutical history rather than the modern pharmacopoeia.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Arsenicum album | Anxiety, restlessness, prostration | Ars-alb is chilly, heat-craving and sips; Ars-iod is hot, heat-worse and air-better. |
| Iodum | Heat, glands, emaciation | Iodum wastes and over-heats with enormous appetite; Ars-iod keeps the Arsenicum anxiety. |
| Sulphur iodatum | Hot skin, glands | Sul-i is the dry hot glandular remedy without the Arsenicum fear. |
| Tuberculinum bovinum | Wandering heat, restlessness | Tuberculinum is the nosode of the hectic constitution; Ars-iod keeps clear arsenical parentage. |
