Garlic for Cold And Flu Support

Research suggests that the available studies linked here do not directly investigate garlic as a cold and flu remedy, and instead focus on COVID-19 disease mechanisms, sensory disruption during infection, co-infection dynamics, and observational factors shaping outbreak outcomes. The included studies consist of observational research, a qualitative interview study with traditional herbalists in Ethiopia, and laboratory and animal model investigations — none of which test garlic supplementation in clinical trials. One study does note that traditional herbalists in Northeast Ethiopia believed plants historically used for coughs and respiratory infections, potentially including garlic, might offer symptomatic benefit, though this remains an untested hypothesis rather than a demonstrated finding. Overall, the evidence base presented here does not allow for any conclusions about garlic's effectiveness for cold or flu support, and readers interested in this topic should seek out studies that directly evaluate garlic interventions in human populations.
