Kali bromatum 30 is the usual home potency of potassium bromide (KBr). Homeopaths classically give it for acne with fidgety hands and agitated sleeplessness, and for a restless, suspicious mind. A properly made 30C contains no measurable bromide. Crude potassium bromide was a 19th-century sedative and anticonvulsant; it causes bromism. Do not swallow lab KBr as “Kali brom.”

This article is for people searching kali bromatum 30 uses or Kali brom for acne. It is not a protocol for epilepsy, psychosis, or stopping isotretinoin.
| Item | Detail |
|---|---|
| Chemical | Potassium bromide, KBr |
| Also written | Kali brom, Kalium bromatum, Kali-br. 30C |
| Crude drug | Historic human sedative/anticonvulsant; still used in veterinary epilepsy |
| Toxicity | Bromism: sedation, confusion, ataxia, acneiform rash; half-life many days |
| 30C / 200C | No measurable bromide if made properly |
| Q / low X / powder | Material salt — not self-care |
| Main classical uses | Acne; fidgety fingers; sleepless agitation; sexual excess in old books |
| Boiron 30C label | Sleeplessness with agitation — traditional, not FDA evaluated |
| Safety in one line | 30C is not KBr; KBr is not a home acne tonic |
Potassium and bromine ions in a 6X tablet are not “nerve food.” The old page that said Kali brom acts on the CNS as a chemical described bromide the drug, which homeopathic 30C is not.
Bromide salts accumulate: renal half-life in humans is often cited around 10–12 days. Toxicity is neuropsychiatric and dermatologic (bromoderma). That is PubChem and toxicology, not a reason to fear a 30C.
It is not an SSRI, not valproate, and not dermatology acne care. A DUT dissertation found Kali bromatum 30CH no better than placebo for acne lesion counts. Uncontrolled Indian acne series cannot overturn that.
Acne: topical retinoids and benzoyl peroxide first. Night terrors and seizures in a child need paediatrics, not bromide folklore. See anxiety and insomnia.
Skin. Acne, especially pustular, on face, chest, shoulders; tendency to scar in some lists. Fidgety picking.
Nerves. Restless fingers; cannot sit; sleepless with agitation (Boiron). Suspicious, night terrors in old paediatric lists — that is not a trial for parasomnias (a 2025 Children review found no Stramonium/Kali-br night-terror RCTs).
Sexual sphere. Boericke’s “sexual excess then collapse” is Victorian language.
| Form | What is in it | Typical use | Repeat |
|---|---|---|---|
| Crude KBr / veterinary syrup | Material bromide | Dog epilepsy under a vet; not human DIY | Poisoning risk |
| Low X / Q if sold | Salt + lactose/alcohol | Avoid | Do not self-prescribe |
| 30C | Empty of KBr | Acute restless-acne picture | Short, then stop |
| 200C | Empty | Constitutional | Not daily |
30C: delay. Material bromide: bromism (confusion, ataxia, rash), GI upset; chloride/saline changes excretion — a hospital problem. See side effects.
Kali brom 30 does not “sedate the CNS” as KBr.
| Remedy | Picture | Not Kali-br when |
|---|---|---|
| Kali bromatum | Restless acne, fidget, agitated insomnia | Quiet, chilly, sticky Graphites skin |
| Calc sulph | Yellow lingering pus | Less mental fidget |
| Sulphur | Hot, itchy, worse heat/bath | Heat keynote stronger |
| Stramonium | Night terror, fear of dark, violence | More terror than fidget-acne |
