Rating (out of 5): 2

Black currant (Ribes nigrum) has a long history of use in traditional European herbal medicine as a remedy for colds and respiratory complaints. The fruits and leaves have been used to prepare teas and syrups believed to help relieve congestion, support immune function, and soothe sore throats. The rationale for its traditional use as a decongestant comes from its high vitamin C content, antioxidant properties (anthocyanins and polyphenols), and mild anti-inflammatory effects, which could theoretically help alleviate cold symptoms and support recovery. However, while black currant is rich in nutrients that support general health, there is limited direct clinical evidence to support its efficacy specifically as a decongestant or cold remedy. Some in vitro and animal studies suggest that extracts of black currant have immune-modulating properties and may inhibit certain viruses, but robust human trials are lacking. Thus, its use for colds is primarily based on tradition and plausible biological rationale rather than strong scientific validation. People may still use black currant in teas or syrups for symptomatic relief, but it should not be considered a substitute for evidence-based treatments. Overall, the evidence supporting black currant’s use as a decongestant for colds is modest and mainly rooted in traditional practice.
