Laurocerasus
Made from cherry laurel — the hedge plant whose crushed leaves release prussic acid, the chemistry of cyanide, and the classical remedy of gasping and blue.
The whole picture, in one breath
Think of a heart that forgets to breathe: gasping, irregular, sighing respiration, a blue dusky face, the heart weak and faltering in concert with the lungs, worse from the least excitement or cold air, and a strange absence of anxiety despite the drama. Gasping cyanosis with a calm mind: that is Laurocerasus.
The substance, in plain words
Cherry laurel is the dense garden hedge whose crushed leaves smell of almonds — hydrogen cyanide released from its amygdalin chemistry. Cyanide blocks cellular oxygen use: its poisonings give exactly the remedy's portrait — gasping, cyanosis, faltering heart, swift collapse.
The traditional picture Classical sources
The inner state
- Strange absence of anxiety. The keynote of the mind: profound uncomplaining calm despite gasping — unlike Arsenicum's terror.
- Irritability. Crossness in the intervals; better alone.
- Despondency. Gloomy in the chronic heart-and-lung states.
The body
- Gasping irregular respiration. The keynote: sighing, gasping, irregular breathing — Cheyne-Stokes-like in the old books.
- Cyanosis. Blue, dusky lips and face; cold sweat; the cyanosis of the newborn in the classical texts.
- Heart and lung together. The cardiac and respiratory failures run in harness — neither leads.
- Worse cold air and excitement. A draught or a shock sets the gasping off.
- Food and warmth load the weakened circulation. Eating aggravates; the books note the small, careful meals of the cardiac.
- Better from warmth and rubbing. External warmth and friction support the faltering powers.

Where it acts (organ affinities)
Heart, respiration and breathing centre, circulation (cyanosis), brain-stem reflexes.
Where the classical picture comes from
Prussic acid's toxicology — swift cyanosis, gasping, collapse — was among the best-described poisonings of the nineteenth century; the proving of the laurel leaf carried the same picture into the library, where it became the remedy of the gasping blue states.
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.
Cyanide chemistry is real and twofold: prussic acid is a lethal poison whose antidote (hydroxocobalamin) modern emergency rooms keep ready, while related nitrile chemistry serves industry and medicine alike. The cherry laurel hedge carries one of nature's most efficient cellular poisons — the remedy's portrait is a faithful photograph of cyanide at work.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Antimonium tartaricum | Gasping, drowsy | Ant-tart is drowsy and rattling; Laurocerasus is gasping and blue. |
| Digitalis purpurea | Failing heart | Digitalis is slow and nauseated; Laurocerasus is cyanotic and respiratory. |
| Carbo vegetabilis | Cyanosis, collapse | Carbo wants air fanned; Laurocerasus gasps quietly, calm and blue. |
| Opium | Stupor, dark face | Opium is stertorous and insensible; Laurocerasus is gasping with a clear mind. |
