Redcurrant (Ribes rubrum) has traditionally been used in some European folk medicine practices for the management of colds and general respiratory discomfort. The fruit is rich in vitamin C and other antioxidants, which may have contributed to its reputation for supporting the immune system and helping the body recover from illness. Historically, redcurrant infusions, syrups, and jams were often consumed during the cold season, and the berries were valued for their refreshing and mildly astringent qualities.

However, while the use is rooted in traditional knowledge, there is limited scientific research directly linking redcurrant consumption to the prevention or treatment of the common cold. The rationale for its use is generally extrapolated from its vitamin C content, which plays a modest role in supporting immune function, though clinical trials on vitamin C for colds have produced mixed results. No robust studies have specifically examined redcurrant as a therapeutic agent for respiratory infections in humans.

In summary, the use of redcurrant for colds is primarily based on tradition, with a low to moderate level of indirect supporting evidence. It remains a popular ingredient in traditional remedies, but more targeted research would be needed to validate its effectiveness for this condition.
