Aconite at a glance
- Aconite is a homeopathic remedy made from monkshood (Aconitum napellus), a plant that is extremely toxic in its raw form.
- It is traditionally used for sudden-onset symptoms: acute anxiety, panic, fever after cold exposure and the early stages of colds and flu.
- There is no good-quality evidence that homeopathic aconite is effective for any health condition. The NHS does not recommend homeopathy as a treatment.
- The raw plant is one of the most poisonous in the UK and must never be handled or ingested. Only the highly diluted homeopathic preparation is used as a remedy.
Aconite is one of the most frequently used remedies in homeopathic practice and one you may have seen on pharmacy shelves labelled as “Aconite 30C”. It is made from monkshood, a striking but extremely dangerous plant, and is traditionally associated with conditions that come on suddenly, particularly after a fright, a shock or exposure to cold weather. This guide covers what it is, what it is traditionally used for, what the evidence actually says and why the safety distinction between the raw plant and the homeopathic preparation matters so much.
What is aconite?
Aconite is a homeopathic remedy derived from Aconitum napellus, commonly known as monkshood, wolfsbane or helmet flower. The plant belongs to the Ranunculaceae (buttercup) family and grows wild across much of Europe, including parts of the UK. It is a tall perennial with distinctive hooded purple flowers and is sometimes grown in gardens as an ornamental plant.
All parts of Aconitum napellus are extremely toxic. The plant contains a group of alkaloids, the most dangerous of which is aconitine, classified as both a cardiotoxin and a neurotoxin. According to Drugs.com, as little as 2 mg of pure aconitine, or roughly 1 g of plant material, can be fatal in adults. Poisoning can occur through ingestion, and even through skin contact with the fresh plant. The MHRA has warned that oral use of crude aconite preparations is banned in the UK except under direct medical supervision, because of the risk of fatal cardiac and neurological effects.
Homeopathic aconite is a very different product from the raw plant. It is prepared through serial dilution and succussion (vigorous shaking), the standard process in homeopathic pharmacy. At the dilutions typically sold (such as 30C), the remedy has been diluted far beyond the point at which any molecule of the original plant would be expected to remain. This is why homeopathic aconite is generally considered physically safe, and also why the scientific community questions how it could have a therapeutic effect.
What is it traditionally used for?
In homeopathic practice, aconite is considered one of the most important acute remedies, meaning it is used for conditions that appear suddenly and intensely rather than for long-standing or chronic complaints. Core Healing Path describes it as the go-to remedy when symptoms come on rapidly after a sudden fright, shock or exposure to cold, dry wind.
The conditions most commonly associated with aconite in homeopathic tradition include:
- Sudden anxiety and panic. This is perhaps the best-known traditional association. Aconite is described in homeopathic texts as the first remedy to consider when a person experiences intense, sudden fear or a panic attack, particularly with restlessness and a feeling that something terrible is about to happen.
- Acute fever. Aconite is traditionally associated with fevers that come on abruptly, often after exposure to cold, dry wind. The person is described as feeling hot, restless and thirsty, with dry skin and a rapid pulse.
- Early stages of colds and flu. In homeopathic practice, aconite is used at the very beginning of a cold or flu-like illness, when symptoms appear suddenly, particularly with sneezing, a dry nose and a sore throat. It is considered most useful in the first hours of onset and less relevant once symptoms have become established.
- Shock and fright. Aconite is traditionally recommended for the emotional and physical effects of a sudden shock, such as witnessing an accident or receiving bad news. Homeopathic texts describe it as being for the person who remains fearful and agitated after a frightening experience.
- Earache and toothache. Sudden-onset ear or tooth pain, particularly after cold exposure, is another traditional indication.
Homeopathic texts describe several modalities associated with aconite:
- Worse: at night (especially around midnight), in cold dry wind, in warm rooms, from fright or shock, from noise and light.
- Better: in open air, with rest, and after perspiration begins.
A key feature of the aconite picture in homeopathy is suddenness. Symptoms appear quickly and intensely. If they develop gradually, or if the person is calm rather than fearful, homeopaths would typically consider a different remedy. These traditional associations come from homeopathic provings and historical clinical use, not from conventional clinical trials.
Aconite 30C is the potency most widely available in UK pharmacies and health shops. In homeopathic notation, 30C means the original substance has been diluted 1:100 thirty times. At this level of dilution, no measurable amount of the original plant would be expected to remain. Lower potencies such as 6C are sometimes used for milder symptoms, while 200C is typically prescribed by a homeopathic practitioner.
Does it work? What the evidence says
Despite aconite’s long history within homeopathic practice, there is no good-quality clinical evidence that it is effective for any health condition.
One small trial has been conducted specifically on homeopathic aconite. A 1990 double-blind, placebo-controlled study by Alibeu and Jobert tested homeopathic aconite in 50 children after surgery, looking at post-operative agitation. The study reported a statistically significant benefit compared with placebo. However, this is a single, small trial that has not been replicated, and it does not meet the standard of evidence needed to draw firm conclusions about effectiveness.
The broader evidence base for homeopathy provides no support for the approach. The most comprehensive review to date was conducted by Australia’s National Health and Medical Research Council (NHMRC). Its 2015 evaluation, which assessed the evidence across a wide range of conditions, concluded that there are no health conditions for which there is reliable evidence that homeopathy is effective.
A systematic review of systematic reviews by Ernst (2002), published in the British Journal of Clinical Pharmacology, reached a similar conclusion: the most methodologically rigorous studies on homeopathy consistently failed to show effects beyond placebo.
The NHS does not recommend homeopathy as a treatment for any health condition.
The one small trial that tested homeopathic aconite directly (Alibeu and Jobert, 1990, 50 children) reported a benefit for post-operative agitation, but a single study of this size cannot be considered reliable evidence. No further trials have replicated the finding. At the 30C potency, the remedy is diluted far beyond the point at which any molecule of the original plant would remain. The scientific consensus, reflected by the NHS and the NHMRC, is that homeopathy has not been shown to be effective beyond placebo for any condition.
How to use homeopathic aconite
If you choose to use homeopathic aconite, the following guidance is based on standard homeopathic practice and product labelling. It is not an endorsement of effectiveness.
Homeopathic aconite is most commonly sold as small sugar or lactose-based pills (pillules) that dissolve under the tongue. Some products are also available as liquid drops.
- Standard dosing (acute use, 30C): one dose (one tablet or a few pillules) dissolved under the tongue, repeated every 30 minutes to two hours depending on the intensity of symptoms. Most homeopathic guidance advises reducing the frequency as symptoms improve and stopping once a clear change is noticed.
- Lower potencies (6C): may be taken more frequently, such as every one to two hours.
- Higher potencies (200C): usually taken as a single dose or very few doses under the guidance of a homeopathic practitioner.
Homeopathic practitioners generally advise taking remedies away from food, drink and strong flavours (especially mint and coffee) by about 15 to 20 minutes.
Always follow the dosing instructions on the specific product you are using. If symptoms persist or worsen, see your GP.
Who should not use it
The raw monkshood plant (Aconitum napellus) is one of the most toxic plants found in the UK. All parts are poisonous. Never handle the fresh plant without gloves, and never ingest any part of the plant or any crude (non-homeopathic) preparation of aconite. As little as 1 gram of plant material can be fatal.
Oral use of crude aconite is banned in the UK except under direct medical supervision. The MHRA has issued warnings about unlicensed products containing aconite.
Homeopathic aconite at standard potencies (6C and above) is a very different product: it is highly diluted and generally considered physically safe. However, it should not be used as a substitute for medical treatment.
If you are pregnant or breastfeeding, speak to your GP, midwife or pharmacist before taking any homeopathic remedy.
Sudden fever with a very high temperature, breathing difficulty, chest pain, severe headache or a panic attack that feels like a medical emergency all need prompt medical assessment, not self-treatment. Call NHS 111, see your GP urgently or call 999 in an emergency.
The safety distinction here is critical. The raw plant is extremely dangerous. WebMD notes that aconitine interferes with sodium channels in the heart and nerves, and that even small amounts of the crude substance can cause fatal cardiac arrhythmias or respiratory failure. Symptoms of aconite poisoning include numbness, tingling, nausea, irregular heartbeat, seizures and difficulty breathing. There is no antidote.
The homeopathic preparation, by contrast, is diluted to the point where no measurable amount of the original substance remains (at 30C and above). At these dilutions, the physical risk from the tablet itself is negligible. The main concern with any homeopathic remedy is the risk of delaying conventional treatment for a condition that needs medical attention.
Healthline notes that some products marketed as containing aconite have been found to contain more of the substance than their labels state, which can pose a genuine safety risk. If you choose to use homeopathic aconite, buy only from reputable UK pharmacies and check the product label carefully.
Common questions
Is aconite 30C safe to take?
Homeopathic aconite at 30C is highly diluted and is generally considered physically safe, because no measurable amount of the original plant would be expected to remain at this dilution. However, the raw plant is extremely toxic. Only the homeopathic preparation should ever be used, and it should not replace medical treatment for any condition.
What is the difference between aconite and monkshood?
They are the same plant. Monkshood (Aconitum napellus) is the common name for the plant from which homeopathic aconite is made. It is also known as wolfsbane and helmet flower. All parts of the plant are highly poisonous and should never be handled without gloves or ingested in any crude form.
Can I give homeopathic aconite to a child?
Some homeopathic products are marketed for use in children, but there is no clinical evidence that they are effective. If your child has a sudden fever, significant pain, breathing difficulty or is distressed, seek medical advice from your GP, pharmacist or NHS 111 rather than relying on a homeopathic remedy.
Does the NHS recommend aconite?
No. The NHS does not recommend homeopathy, including homeopathic aconite, as a treatment for any health condition. If you have symptoms such as sudden fever, panic attacks or persistent pain, your GP can advise you on evidence-based treatment options.
Can aconite poisoning occur from homeopathic tablets?
At standard homeopathic potencies (6C and above), the amount of aconitine remaining in the tablet is negligible, and poisoning would not be expected. However, WebMD notes that some products have been found to contain more aconite than their labels state. Buy only from reputable pharmacies and follow the product label. If you experience numbness, tingling, irregular heartbeat or any unusual symptoms after taking any aconite product, seek medical help immediately.
