Lycopodium at a glance
- Lycopodium is a homeopathic remedy made from the spores of club moss (Lycopodium clavatum), a creeping evergreen plant.
- It is traditionally used for digestive complaints such as bloating and flatulence, right-sided symptoms and low self-confidence.

Lycopodium is one of the most frequently prescribed remedies in homeopathic practice. It is made from club moss, a plant that has been used in folk medicine for centuries. If you have seen lycopodium in a pharmacy or health shop and wondered what it is supposed to do, this guide explains what it is, what homeopaths use it for, what the evidence actually says and what you should know before taking it.
What is lycopodium?
Lycopodium is a homeopathic remedy derived from Lycopodium clavatum, commonly known as club moss, stag’s horn moss or wolf’s claw. Despite its name, club moss is not a true moss. It is a lycophyte, a type of ancient vascular plant that has existed for hundreds of millions of years. It grows as a low, creeping evergreen across heathlands, moors and woodlands in Europe, North America and parts of Asia.
The part used in homeopathic preparation is the spore powder, a fine, yellowish dust produced by the plant’s cone-like structures. This powder has unusual physical properties: it is water-repellent, highly flammable and was historically used in theatrical flash effects, as a coating for pills and in forensic fingerprinting. In folk medicine, club moss was used as a diuretic and for bladder and kidney complaints, though RxList notes that the raw plant is considered possibly unsafe when taken by mouth because it contains several toxic compounds.
Homeopathic lycopodium is prepared through serial dilution and succussion (vigorous shaking), the standard process in homeopathic pharmacy. At the dilutions typically sold, such as 6C or 30C, the final product contains extremely little, if any, measurable amount of the original plant material.
What is it traditionally used for?
In homeopathic practice, lycopodium is considered a major polychrest remedy, meaning it is prescribed across a wide range of conditions. Like all classical homeopathic remedies, it is selected based not only on physical symptoms but also on the person’s overall temperament and how symptoms behave.
The conditions most commonly associated with lycopodium in homeopathic tradition include:
- Digestive complaints. This is the most frequent traditional use. Lycopodium is associated with bloating, flatulence, a feeling of fullness after eating only a small amount, and constipation. Homeopathy UK describes it as being suited to people who experience abdominal distension, often worse in the late afternoon and evening, with a craving for sweets and warm drinks.
- Right-sided symptoms. A distinctive feature of the lycopodium picture in homeopathy is that symptoms tend to be worse on the right side of the body, or to start on the right and move to the left. This includes sore throats, headaches and skin complaints.
- Liver and gallbladder complaints. Lycopodium is traditionally associated with sluggish digestion and discomfort in the liver area, particularly after rich or fatty food.
- Low self-confidence and anxiety. In the homeopathic tradition, the person who “fits” lycopodium is described as someone who may appear confident or even authoritative on the outside but experiences significant self-doubt and fear of failure underneath. Anticipatory anxiety before events or public speaking is another common association.
- Skin conditions. Eczema and dry, cracked skin, particularly on the right side or on the hands and feet, are traditional lycopodium indications.
Homeopathic texts describe several modalities (factors that make symptoms better or worse) associated with lycopodium:
- Worse: between 4 pm and 8 pm, in warm or stuffy rooms, after overeating, from tight clothing around the abdomen.
- Better: in open air, with gentle movement, after warm food and drinks, and after loosening clothing.
These traditional associations come from homeopathic provings (tests conducted within the homeopathic tradition) and historical clinical use, not from conventional clinical trials. The idea that a person’s personality, time of day and side of the body are relevant to prescribing is specific to homeopathy and is not supported by mainstream medicine.
Does it work? What the evidence says
Despite lycopodium’s long history within homeopathic practice, there is no good-quality clinical evidence that it is effective for any health condition.
This is consistent with the wider evidence base for homeopathy as a whole. 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 list homeopathy among the complementary therapies it may offer. It notes that complementary therapies are “not tested in the same way as standard medicines”, and the treatments the NHS provides are chosen based on evidence of how well they work. Homeopathy is not included alongside therapies such as acupuncture or hypnotherapy, which have some evidence in specific contexts.
Homeopathic lycopodium is prepared through extreme dilution. At common potencies such as 30C, the final product is unlikely to contain a single molecule of the original plant material. This is one reason the scientific community questions how homeopathic remedies could have a therapeutic effect beyond placebo. People who use homeopathic remedies often report benefits, but large, well-designed trials have not shown these to be greater than what a placebo produces.
How to use it
Homeopathic lycopodium is widely available from pharmacies and health shops in the UK. It is typically sold as small sugar pills (pillules or granules) that are dissolved on or under the tongue. Less commonly, it is available as drops or tablets.
Common potencies include:
- 6C, sometimes used for everyday complaints and taken more frequently (up to three or four times a day).
- 30C, the most widely sold potency for self-care, usually taken once or twice a day for a few days.
- 200C, a higher potency typically prescribed by a homeopathic practitioner rather than self-selected.
General guidance from homeopathic suppliers suggests taking the remedy away from food, drink and strong flavours (such as mint or coffee) by at least 15 minutes. If symptoms have not improved within a few days, most homeopathic guidance advises stopping the remedy rather than continuing indefinitely.
Because of the extreme dilution involved, homeopathic lycopodium is not the same product as the raw plant. The safety concerns that apply to club moss in its crude form (see below) do not apply to the highly diluted homeopathic preparation in the same way.
Who should not use it
Homeopathic lycopodium at standard potencies (6C and above) is generally considered physically safe for most adults because of the extreme dilution. However, there are important points to be aware of.
Do not use homeopathic lycopodium as a substitute for medical treatment. If you have digestive symptoms that are persistent, worsening or accompanied by unexplained weight loss, blood in your stools or severe pain, see your GP.
If you are pregnant or breastfeeding, speak to your GP, midwife or pharmacist before taking any remedy, including homeopathic preparations.
The raw plant (club moss) is considered possibly unsafe when taken by mouth and should not be used as a herbal remedy. It contains toxic compounds and may interact with certain medications, including drugs for Alzheimer’s disease and anticholinergic medications.
If you are taking any prescribed medication, check with your pharmacist before starting a homeopathic remedy alongside it.
The raw plant, Lycopodium clavatum, is a separate matter. According to RxList, crude club moss is rated as possibly unsafe because it contains several toxic compounds. It may worsen existing conditions including slow heart rate, stomach ulcers, asthma, seizure disorders and urinary tract obstruction. It should not be confused with Chinese club moss (Huperzia serrata), which contains huperzine A and is a different plant entirely.
Common questions
Is lycopodium the same as club moss?
Lycopodium clavatum is the botanical name for club moss, so they are the same plant. However, in practice, “lycopodium” usually refers to the homeopathic remedy made from the plant’s spores, while “club moss” refers to the plant itself. The homeopathic preparation is extremely diluted, so it is a very different product from the crude plant material.
What potency of lycopodium should I take?
For self-care, 30C is the most commonly sold potency in the UK. Some people use 6C for milder or more frequent dosing. Higher potencies such as 200C are usually prescribed by a homeopathic practitioner. There is no good-quality clinical evidence to guide potency selection, and the choice is based on homeopathic tradition rather than conventional research.
Can I take lycopodium for bloating?
Lycopodium is one of the remedies most commonly associated with bloating in homeopathic tradition. However, there is no clinical evidence that it is effective for this or any other digestive complaint. If you experience persistent bloating, it is worth speaking to your GP to rule out underlying causes before relying on any remedy.
Is lycopodium safe during pregnancy?
The homeopathic preparation at standard potencies is highly diluted, but there is limited safety data for any homeopathic remedy during pregnancy. The raw plant is considered possibly unsafe. As a precaution, speak to your GP or midwife before taking lycopodium or any other remedy during pregnancy.
Does the NHS recommend lycopodium?
No. The NHS does not recommend homeopathy, including lycopodium, as a treatment for any health condition. If you have symptoms that are affecting your daily life, your GP can advise you on evidence-based options.
