Kali bichromicum
Made from potassium dichromate — the orange salt of the chrome industry whose ulcers are occupational-disease history, and the classical remedy of stringy mucus.
The whole picture, in one breath
Think of strings and punched-out holes: mucus so ropy it can be drawn out in long threads, sinus pain at a single precise point, ulcers with sharply cut, punched-out edges, and wandering rheumatism that appears exactly where the stringy catarrh sits. Ropy strings, punched-out ulcers, pinpoint sinus pains: that is Kali bichromicum.
The substance, in plain words
Potassium dichromate is the orange crystalline salt of the chrome-plating industry — genuinely corrosive, genuinely carcinogenic in the workplace ('chrome ulcers' are occupational-medicine classics). The proving turned its ulcerating, string-forming action into the library's most precise mucous-membrane portrait.
The traditional picture Classical sources
The inner state
- Dullness of the catarrhal. Despondent, worse at night, slow to think with the heavy sinuses.
- Irritability. Crossness from the fixed, boring pains.
- Anxiety about health. The books pair it with the worried chronic sinus and ulcer sufferer.
The body
- Ropy, stringy mucus. The keynote: mucus tough and stringy, drawn out in long threads — from nose, throat, larynx, vagina.
- Punched-out ulcers. Ulcers with sharply defined, cut-out edges — on the skin, mouth, stomach; the books' ulcer-remedy par excellence.
- Pinpoint sinus pains. Sinusitis with pain at one small, exact spot; pain that wanders with the catarrh.
- Better heat. Warmth relieves — unlike most catarrhal remedies; the person wants the throat wrapped.
- Worse morning and damp. The sinuses fill overnight; damp chills bring the wandering rheumatic pains.
- Ulcerated throat and larynx. Ulcers on the tonsils and cords with the stringy exudate — the old diphtheria-era picture.
Modalities (worse and better factors)
| Worse from ⬇ | Better from ⬇ |
|---|---|
| damp cold weather; morning; cold air | warmth; hot drinks; lying |
Where it acts (organ affinities)
Mucous membranes (sinus, throat, stomach), ulcers, bones and joints (wandering), skin.
Where the classical picture comes from
The dichromate's corrosive chemistry produced strings and punched ulcers in proving; the remedy then mapped perfectly onto the diphtheritic membranes and chronic sinuses of the pre-antibiotic era — a case where poison and prescription saw the same lesion.
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.
Dichromate is real and dangerous occupational medicine: chrome ulcers and nasal perforation of plating workers are textbook industrial disease, and hexavalent chromium is a recognised carcinogen. The salt's chemistry built the chromium industry and its dermatology at once; it is a genuine, if grim, pharmacological landmark.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Hydrastis canadensis | Ropy yellow mucus | Hydrastis ropes come with torpid debility; Kali-bich's ropes are tough, and its ulcers are punched-out. |
| Hepar sulphuris | Ulcers, suppuration | Hepar's ulcers are touchy and early-suppurating; Kali-bich's are punched-out and stringy. |
| Mercurius solubilis | Throat ulcers, offensiveness | Mercurius is sweaty and foul at night; Kali-bich is stringy and precise. |
| Aurum metallicum | Nasal and bone complaints | Aurum's nasal troubles come with proud despair and heart; Kali-bich's with strings and pinpoint pain. |
