Mezereum
Made from mezereon — the February daphne whose blistering bark was an official counter-irritant, and the classical remedy of crusted eruptions that burn under the crust.
The whole picture, in one breath
Think of skin that burns beneath its own crust: thick, chalky, offensive crusts — scalp, face, eyebrows — under which the skin burns and itches maddeningly; worse at night, worse for the warmth of the bed, and the books' syphilitic-skin legacy all around. The burning-under-the-crust remedy: that is Mezereum.
The substance, in plain words
Mezereon is the purple-flowered shrub of late winter, its bark a violent blisterer — an official counter-irritant of the old pharmacopoeias, applied to raise blisters on purpose. Its daphnin and mezerein chemistry genuinely burns skin; the proving gave the classical crust-and-burn portrait.
The traditional picture Classical sources
The inner state
- Anxiety and restlessness. Fretful, worse at night with the itching; the books note the anxious skin-sufferer.
- Irritability. Cross, worse from heat and from being questioned.
- Despondency. Gloomy in the chronic crusted states.
The body
- Thick chalky crusts. The keynote: thick, white-chalky, offensive crusts of the scalp, face and eyebrows; the hair sticks in them.
- Burning under the crust. The skin beneath burns and itches — the quoted Mezereum sign; worse scratching
- Worse warmth of the bed. Heat and the bed's warmth drive the itching wild; cool air relieves.
- Zona and neuralgia. The books add it to the zona (shingles-like) and post-eruption neuralgias.
- Night aggravation. The whole picture owns the night.
- Syphilitic-skin legacy. The old books pair it with the inherited skin legacy of the era's great hidden disease.

Where the classical picture comes from
The blistering bark's official career — blister-plasters on purpose — gave the proving its frame: burns beneath the crust, heat-madness, night-ownership. Mezereum became the classical crusted-skin remedy of the pre-steroid era.
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.
Mezereon bark was a genuine, official counter-irritant of the pharmacopoeias — its blistering chemistry real and violent, since retired along with the whole blister-plaster era. The crusted skin diseases it portrayed — eczema, psoriasis, seborrhoea — are today dermatology's everyday territory, managed with steroid and vitamin-D creams.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Petroleum | Crusty winter skin | Petroleum cracks in winter cold; Mezereum crusts thickly and burns beneath. |
| Graphites | Oozing crusted skin | Graphites oozes sticky honey; Mezereum burns under chalky crusts. |
| Arsenicum album | Burning skin, restlessness | Arsenicum is anxious, chilly and sipping; Mezereum crusted, burning and heat-mad. |
| Dulcamara | Crusty scalp, damp | Dulcamara's crusts follow the damp; Mezereum's burn underneath. |
