Kali bromatum
Made from potassium bromide — the Victorian sedative that calmed seizures and then poisoned a generation, and the classical remedy of numbed nerves and ruined skin.
The whole picture, in one breath
Think of a mind dulled by its own chemistry: once-excited nerves now blunted, memory failing, hands that feel anaesthetic, skin broken out in acne that scars, and a sexual vitality first overstimulated then extinguished. Bromide dullness: that is Kali bromatum.
The substance, in plain words
Potassium bromide was the first reliable anti-seizure drug — it ended the brutality of epilepsy treatment in 1857 and then, as 'bromide calm' spread through asylums and drawing rooms, created the poisoning called bromism: acne, dulled mind, staggering gait, anaesthesia, impotence. The proving simply wrote the poison down.
The traditional picture Classical sources
The inner state
- Mental dullness and blunting. The keynote: mind feels wrapped in cotton, memory fails, comprehension lags — the bromide fog.
- Anxiety about health. Fear of insanity, of being alone, of impending paralysis — beneath the dullness.
- Restlessness fidgeting. Busy, aimless movement of hands and feet; picking at things.
The body
- Anaesthesia of skin and parts. The famous sign: patches of skin that feel numb, dead, insensible — the bromide anaesthesia.
- Acne that scars. Pustular acne of the face and shoulders, leaving pits and scars; the books' scar-acne remedy.
- Sexual excitement then impotence. The bromide arc: first overstimulation, then complete loss — quoted in the proving.
- Brain fag. Headache of students, worse for mental effort, with the cotton-wool mind.
- Trembling and weakness. Hands tremble, knees unsteady, gait wavering — the bromide stagger.
- Worse at night and from emotion. The fog thickens at night; emotional shocks bring the anxiety forward.

Where it acts (organ affinities)
Nerves and brain, skin (anaesthetic, acne), sexual organs, senses.
Where the classical picture comes from
Bromism was the defining iatrogenic disease of the bromide era: acne, anaesthesia, impotence and mental fog in patients 'calmed' for decades. The proving and the wards agreed so completely that Kali-brom's portrait is essentially a case series in bromide poisoning.
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.
Bromide's medical legacy is genuine and double-edged: it was the first anticonvulsant — the ancestor of all epilepsy drugs that followed — and its toxicology coined 'bromism'. Modern sedatives and antiepileptics inherited its mission without its poison; the portrait on this page is the history of the transition.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Sulphur iodatum | Acne, hot skin | Sul-i is hot, dry and glandular; Kali-brom is foggy, numb and scarred. |
| Agnus castus | Sexual depression | Agnus is grief-wrecked vitality with coldness; Kali-brom is chemically blunted. |
| Kali phosphoricum | Brain-fag | Kali-phos is grey anxious exhaustion; Kali-brom is cotton-wool blunting. |
| Petroleum | Acne worse in winter | Kali-brom's acne scars with numb fog; Petroleum's skin cracks in winter cold. |
