Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Flavanones, a subclass of flavonoids commonly found in citrus fruits such as oranges, lemons, and grapefruits, have attracted attention for their potential antiviral and immune-supporting properties. Scientific evidence supporting their use against colds is limited but emerging. In vitro studies have demonstrated that certain flavanones, like hesperidin and naringenin, can inhibit the replication of some respiratory viruses, including influenza and rhinoviruses, which are common causes of the cold. These compounds may also modulate immune responses by exhibiting antioxidant and anti-inflammatory effects, potentially alleviating symptoms associated with viral infections.

However, most of the evidence comes from laboratory and animal studies, with limited data from well-designed clinical trials in humans. A few small-scale clinical studies suggest that flavanone-rich extracts might reduce the duration or severity of cold symptoms, but these findings are preliminary and not universally replicated. Traditional medicine systems have not specifically highlighted flavanones as cold remedies, but citrus fruits have been commonly consumed for general health and immune support.

Overall, while there is some scientific rationale and early evidence for the antiviral and immunomodulatory effects of flavanones, robust clinical evidence is lacking. Thus, their use for colds can be considered scientifically plausible but not yet strongly validated.
