Prunus spinosa
Made from the blackthorn — the hedgerow of the same stone-fruit family as the cherry laurel, and the classical remedy of the heart's oppression and the neuralgic pain.
The whole picture, in one breath
Think of a heart oppressed with anxiety: a sensation of oppression and anxiety about the heart, difficulty breathing lying down, darting, wandering neuralgic pains that come and go, a toothache that drives the sufferer frantic, and the books' prickly-shrub remedy of the heart and the nerve. The oppressed-heart remedy: that is Prunus spinosa.
The substance, in plain words
The blackthorn is the spiny hedgerow shrub of Europe, its sloe fruit and bark kin to the stone-fruit family that carries the same amygdalin chemistry as the cherry laurel — the family of prussic acid. The proving gave the remedy its heart-oppression and neuralgia portrait.
The traditional picture Classical sources
The inner state
- Anxiety about the heart. The keynote of the mind: a fixed anxiety and oppression about the heart, worse in the quiet hours.
- Restlessness with the pain. Unable to settle with the darting, wandering pains.
- Irritability. Cross, worse from contradiction and noise.
The body
- Oppression of the heart. The keynote: a sense of oppression and constriction about the heart with the anxiety — lying down makes the breathing worse.
- Darting, wandering neuralgic pains. Pains that come and go, darting from place to place — the books' wandering neuralgia.
- Violent toothache. Toothache so severe it drives the sufferer frantic, shooting into the head and ear.
- Numbness and tingling. The parts grow numb and tingle around the pains — the prunus-family nerve shading.
- Worse cold damp and night. Wet weather and night deepen the heart and the pains.
- Better for open air and motion. Gentle motion and fresh air ease the oppression.

Where the classical picture comes from
The hedgerow blackthorn's proving gave the heart-oppression and wandering-neuralgia portrait; the old books applied it to the anxious, oppressed constitutions whose pains wandered — a shrub of the same family as the cyanide-bearing laurel, carrying its own faint shadow.
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.
The Prunus family's amygdalin chemistry — the same seed-cyanide system as the cherry laurel — is genuine, documented plant toxicology, mild in the sloe but real in the family's chemistry. The heart-oppression it portrayed is modern cardiology's territory: the anxious chest is assessed, the heart is examined, and real answers exist. The shrub's chemistry is its family's; its portrait is its own.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Cactus grandiflorus | Heart constriction | Cactus is the iron band with the left arm; Prunus spinosa the oppression with the anxiety and the wandering neuralgia. |
| Spigelia anthelmia | Neuralgic pains | Spigelia's are left-sided and pulse-synchronous; Prunus' darting and wandering with the heart. |
| Laurocerasus | The prunus family | Laurocerasus is the gasping cyanotic calm of the same chemical family; Prunus the oppression with the anxiety. |
| Argento-nitricum | Heart anxiety | Arg-nit is the hurried anticipatory anxiety; Prunus the fixed oppression about the heart. |
