Ranunculus sceleratus
Made from the cursed crowfoot — the marsh buttercup whose blistering juice has the name to prove it, and the classical remedy of the burning blister and the shingles-like nerve.
The whole picture, in one breath
Think of blisters that burn like fire: the burning, smarting blisters of the buttercup chapter, the vesicular eruption along the nerve of the shingles-like state, the raw mouth and ulcerated gums, and the cursed crowfoot's own chemistry as symptom. The burning-blister remedy: that is Ranunculus sceleratus.
The substance, in plain words
The cursed crowfoot is the marsh buttercup of Europe, its name meaning exactly what it does — the blistering, burning juice that raises wheals on the hands of pickers. Its ranunculin-protoanemonin chemistry is genuinely vesicant, the buttercup family's shared weapon. The proving gave the remedy the blister-and-nerve portrait.
The traditional picture Classical sources
The inner state
- Anxiety and irritability. Cross, worried, worse at night with the burning.
- Restlessness. Unable to settle with the smarting and the itching.
- Despondency. Gloomy in the chronic, recurrent states.
The body
- Burning, smarting blisters. The keynote: blisters that burn like fire — the books' most burning member of the buttercup chapter.
- Shingles-like nerve eruption. The vesicular eruption following the nerve of the zona state, as in its bulbous cousin.
- Raw mouth, ulcerated gums. The mouth burns and ulcers — the crowfoot's juice as symptom.
- Deep, foul ulcers. The books add the deep, foul, obstinate ulcers of the same chemistry.
- Worse cold damp and night. Wet weather and night deepen the burning.
- Better for rest and cool air. Rest and cool air ease the smarting.

Where the classical picture comes from
The cursed crowfoot's blistering juice gave the proving its burning portrait; Ranunculus sceleratus became the classical remedy of the most burning blisters — the buttercup family recorded in its sharpest, most burning member.
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.
Protoanemonin is genuinely vesicant — the buttercup family's real chemistry, the reason the plants are left alone by grazing animals and the reason pickers learn quickly. The shingles it portrayed is now the varicella-zoster virus, diagnosed and treated with real antivirals; the chemistry is a genuine, documented poison.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Ranunculus bulbosus | The buttercup pair | Ran-bulb is the intercostal neuralgia and zona of the chest; Ran-scel the most burning blisters and the mouth. |
| Clematis erecta | Buttercup family | Clematis is the urinary blisterer; Ranunculus sceleratus the burning mouth and nerve. |
| Cantharis vesicatoria | Burning blisters | Cantharis burns with the urinary urging; Ran-scel with the raw mouth and the nerve. |
| Arsenicum album | Burning pains | Arsenicum's burn at midnight with the anxiety; Ran-scel's blister and burn like fire. |
