Caladium seguinum
Made from dumb cane — the tropical houseplant whose calcium-oxalate needles genuinely sting the mouth, and the classical remedy of the tobacco itch.
The whole picture, in one breath
Think of an itch that owns the skin: intolerable pruritus of the genitals and skin, an aversion to — yet craving for — tobacco with itching on its use, a red, puffy, asthmatic breathing, and the books' great tobacco-antidote portrait. The itching tobacco remedy: that is Caladium.
The substance, in plain words
Dumb cane is the common tropical houseplant whose leaves carry needle-like calcium-oxalate crystals — genuinely stinging and swelling the mouth of anyone who bites it, a real toxicology of the windowsill. The proving gave the remedy its portrait of itching, asthma and the tobacco aversion.
The traditional picture Classical sources
The inner state
- Anxiety and fear. Fear of the itching's return, of suffocation; worse at night.
- Irritability. Cross, worse from heat and from the tobacco craving.
- Forgetfulness. The books note a foggy, forgetful mind with the complaints.
The body
- Intolerable genital itching. The keynote: maddening pruritus of the genitals and skin, worse scratching
- Tobacco aversion with craving. The celebrated keynote: the person craves tobacco yet itches when they use it — the books' great tobacco-antidote remedy.
- Asthmatic breathing. Red, puffy face with difficult, wheezing respiration.
- Worse heat and night. Warmth and the night drive the itching wild.
- Itching eruptions. Papular, itching eruptions of the skin — the dumb-cane chemistry on the surface.
- Better for cool air and rest. Cool open air and quiet ease the pruritus.
Modalities (worse and better factors)

Where it acts (organ affinities)
Skin (pruritus, genitals), respiratory tract, tobacco reactivity, mind.
Where the classical picture comes from
The windowsill toxicology — the plant that punishes the curious mouth — gave the proving its itching portrait; Caladium became the classical remedy of the tobacco itch and the intolerable pruritus, a houseplant with a genuine chemistry and an unexpected medical footnote.
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.
Calcium-oxalate raphides are genuinely irritating — the plant's crystals wound the mouth on contact, a real, documented mechanism of houseplant poisoning. The tobacco reactivity it portrayed is now understood as contact and allergic dermatitis; the itching is dermatology's, and the asthma is respiratory medicine's. The chemistry is real; the career is the windowsill's.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Petroleum | Itchy winter skin | Petroleum cracks in winter cold; Caladium itches with the heat and the tobacco. |
| Sulphur | Itchy burning skin | Sulphur is hot, red and bath-hating; Caladium itches with the tobacco trigger. |
| Psorinum | Offensive itching | Psorinum is filthy, freezing and winter-long; Caladium heat-driven and tobacco-linked. |
| Arsenicum iodatum | Hot itchy skin | Ars-iod is hot, restless and exfoliating; Caladium itches with the genital focus. |
