The Centers for Disease Control and Prevention (CDC) estimates that at least 24 million people have been sick with the flu so far this year's cold and flu season. While antiviral medications are available and can effectively reduce the severity of flu symptoms, they have shortcomings, making them a suboptimal solution for some.
Homeopathy offers a possible alternative solution for helping people recover faster from the flu. According to the 2012 National Health Interview Survey, an estimated 5 million adults and 1 million children in the U.S. used homeopathic remedies.
One popular over-the-counter homeopathic remedy, Oscillococcinum (pronounced "o-sill-o-cox-see-num"), has been marketed as a treatment that may help reduce the severity and duration of flu symptoms. It provides an option for those looking for more natural or supplementary ways to manage their illness.

What Is Oscillococcinum?
Oscillococcinum was first developed by French physician Joseph Roy between 1917 and 1925. While studying the blood of individuals with Spanish flu, Roy identified what he thought were "oscillating bacteria" (hence the name Oscillococcinum). He then isolated this bacterium in the liver of a Long Island duckling.
It is important to clarify that the Oscillococcinum bacterium does not actually exist, and bacteria do not cause the flu (viruses do). It remains unclear exactly what Roy identified in his research.
Although his discovery did not lead to a breakthrough in flu research, it became the foundation for the now-popular homeopathic remedy, which has been used for nearly 80 years and is available in 50 countries.
Oscillococcinum is marketed as a treatment for flu-like symptoms, including body aches, headache, fatigue, fever, and chills.
How Is Oscillococcinum Made?
Homeopathy is a system of alternative medicine developed in the late 18th century by German physician Samuel Hahnemann. The core principles of homeopathy are based on two key ideas:
- "Like cures like" – a substance causing symptoms in a healthy person can be used to treat similar symptoms in a sick person.
- "Law of minimum dose" – the more diluted a substance, the more effective it becomes
The Homeopathic Process
Oscillococcinum's product label lists its active ingredient as Anas barbariae, hepatis et cordis extractuma 200CK. 200CK means that the original substance (active ingredient) has been homeopathically diluted 200 times at the rate of 1 to 100.
Homeopathic dilutions involve repeatedly mixing a small amount of the original substance with a solvent, typically water or alcohol, at a set ratio. In the case of Oscillococcinum, the original substance is Anas barbariae (a species of wild duck) heart and liver. This dilution process is repeated 200 times, with each step followed by succussion, or vigorous shaking, to potentize the remedy.
The result is a highly diluted solution that, according to homeopathic principles, retains the "energetic imprint" of the original substance, believed to trigger the body's healing response.
Does Oscillococcinum Work?
The evidence regarding the effectiveness of this homeopathic remedy for treating flu-like symptoms is mixed and generally inconclusive.
Studies Supporting Oscillococcinum
Several studies suggest Oscillococcinum may have a mild effect on flu symptoms. A 2007 review of complementary medicine for treating and preventing flu-like illnesses concluded that compared to a placebo, Oscillococcinum had a small yet statistically significant effect on reducing the time for symptom resolution.
Specifically, findings from two of the studies included in this review suggested the remedy reduces the severity and shortens the duration of flu-like symptoms:
- In one study, 63% of patients taking Oscillococcinum showed improvement or complete resolution of symptoms within 48 hours.
- In the second clinical trial, the recovery rate from flu symptoms within 48 hours of treatment was greater in the patients taking Oscillococcinum than those who received a placebo.
Another study found that administering Oscillococcinum alongside conventional treatment to patients with COPD after exposure to influenza reduced the number and duration of upper respiratory tract infections and COPD exacerbations compared to conventional therapy alone.
Studies Refuting Its Effectiveness
However, the overall consensus in the medical literature is that Oscillococcinum does not have a significant effect beyond placebo. The CDC Yellow Book explicitly states that no strong evidence supports the claims that Oscillococcinum prevents or treats influenza or influenza-like illness.
A 2010 systematic review concluded that the best available clinical evidence does not support the use of homeopathic medicines, including Oscillococcinum, beyond placebo effects.
Benefits and Drawbacks
While Oscillococcinum has garnered attention for its potential benefits, it's also important to consider the criticisms and concerns raised by the scientific community.
Potential Benefits
- Reported Symptom Relief: The studies discussed above have suggested that Oscillococcinum may reduce the duration and severity of influenza-like symptoms, especially when taken at the first sign of flu-like symptoms.
- Safety: According to the manufacturer, Oscillococcinum does not cause drowsiness or have known drug interactions.
- Ease of Use: Oscillococcinum is formulated as small pellets that dissolve under the tongue. The pellets should be taken every six hours, up to three times a day, for up to three days.
- Accessibility: It is widely available in drugstores and health stores, making it accessible to the general public without a prescription.
Limitations and Criticisms
- Lack of Active Ingredients: Oscillococcinum is prepared through serial dilution to the point where no molecules of the original substance remain. This is a fundamental criticism of homeopathy, as it challenges the plausibility of any pharmacological effect.
- Criticism from the Scientific Community: The majority of high-quality evidence indicates that Oscillococcinum does not have a significant effect beyond placebo. The overall consensus in the medical literature is that the evidence is inconclusive and often limited by small sample sizes and methodological flaws.
Is Oscillococcinum Safe?
Oscillococcinum is generally considered safe when used as directed. Since it is highly diluted, it is unlikely to cause harm or significant side effects. According to a Cochrane review of homeopathic Oscillococcinum that included six studies, only one patient reported a headache from taking the remedy.
Some patients may report a temporary exacerbation of symptoms, or "homeopathic aggravation," after taking a homeopathic remedy. Clinical studies rarely mention this response, but patients should always be mindful of and discuss any changes in symptoms with their doctor.
Oscillococcinum's manufacturer recommends talking with your doctor before taking this medicine if you are:
- Under the age of two
- Pregnant
- Diabetic
Alternatives to Oscillococcinum
While Oscillococcinum may be one option for managing flu symptoms, let's also explore some of the other available homeopathic remedies and conventional medical options for flu relief.
Other Homeopathic Remedies for Flu Relief
Homeopaths believe that remedies should be chosen based on a person's unique pattern of symptoms rather than just the disease itself. Remedies are selected by matching characteristics such as the severity, timing, and triggers of symptoms, as well as the person's overall temperament.
Examples of other homeopathic remedies that may be used as part of a cold and flu treatment plan, based on specific flu-like symptoms, include:
- Belladonna for a high fever characterized by a hot, red face and profuse sweating
- Eupatorium perfoliatum for bone pain
- Sulphur iodatum for fatigue and lingering nasal congestion and after the flu
Conventional Medical Options
Most people with flu have mild illness and do not need medical care. Palliative/supportive interventions, including rest, hydration, and medications to manage fever and pain, are sufficient for healthy individuals with mild symptoms.
The CDC recommends antiviral treatment for:
- Any patient with confirmed or suspected influenza who is hospitalized
- Patients with severe illness
- Patients at increased risk for influenza-associated complications, such as elderly individuals, pregnant women, and those with chronic medical conditions
Four antiviral drugs are FDA-approved and recommended by the CDC to treat flu:
- Oseltamivir
- Zanamivir
- Peramivir
- Baloxavir
Antiviral medications should be started within 48 hours of symptom onset to maximize their efficacy.
