Aconitum Napellus, prepared from the monkshood plant, is one of homeopathy's principal acute remedies — indicated for conditions with sudden, dramatic onset marked by fear, shock, and intense restlessness. It is often the first remedy considered in the earliest hours of an acute fever, after a fright, or following sudden exposure to cold, dry wind. Used appropriately, in the potentised (serially diluted) form prepared by a licensed homeopathic pharmacy, Aconite is considered safe — though it is worth understanding that the source plant itself is highly toxic in its crude, unprocessed form.
Understanding Aconite's Profile
Aconitum Napellus, or monkshood, is a genuinely toxic plant in its raw state — the alkaloid aconitine is poisonous even in small crude quantities. Homeopathic Aconite is prepared through a regulated process of serial dilution and succussion that renders it safe for use as manufactured by licensed pharmacies, and is entirely distinct from the raw herb. Its keynote mental state is sudden fear and anxiety with marked restlessness, often with a distinct fear that death is imminent, alongside physical symptoms of sudden high fever, dry skin, and intense thirst.
Common Uses
Aconite is best known for early-stage feverish illness — the first 24 hours, before any sweating has begun — when the onset was abrupt and the person is anxious and restless with it. It is also considered for acute anxiety or panic following a genuine fright, shock, or accident, for croup and sudden respiratory symptoms that follow exposure to a cold, dry wind, and for acute earache with the same sudden, wind-exposure history.
How It Fits Constitutional & Acute Homeopathic Care
Aconite is generally used as an acute, short-term remedy rather than a constitutional one — matched to a specific triggering event and a clear symptom picture rather than a person's long-term overall pattern. A homeopath distinguishes it from other early fever remedies such as Belladonna or Ferrum Phosphoricum largely by the presence of marked fear and anxiety and a clearly identifiable triggering event, such as a fright or cold wind exposure.
Safety Considerations & When Not to Self-Prescribe
Homeopathic Aconite, sourced from a licensed pharmacy and used as part of an individualised case assessment, is considered safe. It is not, however, a substitute for emergency medical care — high fever accompanied by a stiff neck, seizure, breathing difficulty, or a rapidly deteriorating state needs immediate medical attention regardless of any remedy given. It is also important never to confuse homeopathic Aconite with raw herbal Aconitum preparations, which remain genuinely toxic and should never be ingested.

Aconite 30 vs Aconite 200: Uses and Differences
Aconite (Aconitum Napellus) is homeopathy's classic remedy for sudden, intense onset — a cold or fever that comes on within hours of exposure to cold dry wind, or acute fear and panic after a shock.
Aconitum napellus (monkshood) is a highly poisonous plant. Only properly potentised homeopathic preparations are safe; the mother tincture and very low potencies must never be self-administered. Chest pain, difficulty breathing, a high fever in an infant, or panic with chest symptoms needs emergency medical care first.
| Potency | Generally used for | How it is usually used |
|---|---|---|
| Aconite 30 | The first hours of a sudden cold, sore throat or fever after cold dry wind; acute fright and restlessness. | An acute-stage remedy used early and for a short time; it is usually replaced by another remedy if symptoms settle into a later stage. |
| Aconite 200 | Intense acute fear, panic or shock (for example after an accident or a frightening event), and long-standing fears that date back to a shock. | Given sparingly and normally chosen by a homeopath. |
This is general materia medica information, not a prescription. Potency, dose and how often to repeat it should be set by a qualified homeopath after a full case assessment.
Using homeopathic medicines safely
Keep medicines out of reach of children. Store them in a cool, dry place, away from direct sunlight and strong smells such as camphor, menthol or perfume. Don't exceed the dose or frequency your homeopath advises, and seek advice if symptoms get markedly worse.
Aconite: Frequently Asked Questions
What is Aconite 30 used for?▾
Aconite 30 is traditionally used at the very start of a sudden cold, sore throat or fever — especially after exposure to cold dry wind — and for acute fright with restlessness. It is an early-stage remedy used for a short time. The right potency and how often to take it depend on your full case, so a qualified homeopath should decide this.
What is Aconite 200 used for?▾
Aconite 200 is generally used for intense acute fear, panic or shock, and in constitutional cases where fears began after a frightening event. It is a higher potency used sparingly, usually on a homeopath's advice.
Is homeopathic Aconite poisonous?▾
The raw plant is highly poisonous. Properly potentised homeopathic Aconite (such as 30 or 200) is diluted far beyond any toxic dose, but the mother tincture and very low potencies must never be self-administered.
When should I see a doctor instead of taking Aconite?▾
Seek urgent medical care for chest pain, breathlessness, a high fever in a baby, confusion, a stiff neck with fever, or panic attacks with chest symptoms. Homeopathy can be used alongside medical care, not instead of it, in these situations.
