Garlic is one of the most well-known natural ingredients associated with immune support in traditional medicine. But what does modern scientific evidence say about its role in easing cold symptoms? A recent health report highlights its potential benefits while emphasizing that findings are still limited and require further research.

According to a report published by Al Arabiya Net, referencing the medical site Verywell Health, consuming garlic—especially aged garlic extract—may help support the immune system, reduce the severity of some cold symptoms, and possibly speed up recovery for some individuals.
The report notes that garlic contains biologically active compounds, particularly sulfur compounds, which play a role in stimulating the immune response. According to a study cited in the report, taking aged garlic extract daily for 90 days increased the activity of certain immune cells, which could help the body fight cold-causing viruses more effectively.
Increased immune cell activity means the body can recognize and attack pathogens earlier, which may influence symptom severity.
Garlic’s potential effects are not limited to prevention; it may also help alleviate cold symptoms themselves. The report explains that some people who consumed aged garlic extract noticed a reduction in the severity of upper respiratory symptoms, such as sore throat, cough, and nasal congestion. Experts attribute this to garlic’s anti-inflammatory properties, along with its role in enhancing the body’s ability to respond quickly to infections, which may reduce symptom intensity.
Does Garlic Shorten the Duration of a Cold?
Although garlic is not a direct cure for colds, the report indicates that it may help reduce the number of days a person feels extreme fatigue or unable to carry out daily activities normally. Some evidence also suggests that regular garlic consumption might lower the number of colds a person experiences during a season, although these findings still require larger studies for confirmation.
The report warns that consuming whole garlic in daily meals is safer than relying on supplements, which may carry risks for certain groups—such as increased bleeding risk for those on blood thinners—or may not be suitable for pregnant or breastfeeding women.
Side effects of natural garlic are generally mild, including bad breath or minor digestive discomfort in some individuals.
In conclusion, garlic cannot be considered a magical cure for the common cold, but it may support immunity and relieve some symptoms when included in a balanced diet. Following general medical advice—such as rest, staying hydrated, and consulting a doctor if symptoms worsen—remains the cornerstone of managing colds.
