Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Buckthorn (most commonly referring to the Rhamnus genus, such as Rhamnus cathartica or Frangula alnus) has a long history of use in traditional herbal medicine, primarily as a laxative and for digestive complaints. Its use for colds or as an antiviral remedy is less common and not widely documented in scientific literature. Some traditional European herbal practices have included buckthorn in mixtures intended to support the immune system or as general tonics during illness, which might extend to cold care. However, there is very limited direct evidence regarding its effectiveness against viral infections like the common cold. Most of the available information focuses on its purgative effects due to anthraquinone glycosides.

Scientific studies specifically investigating buckthorn’s antiviral properties are minimal. The related plant sea buckthorn (Hippophae rhamnoides) is sometimes confused with Rhamnus species and does have some preliminary evidence for immune support, but this does not apply to true buckthorn. Therefore, the use of buckthorn for colds is justified primarily by traditional, anecdotal use rather than robust scientific validation. The evidence rating is low, reflecting a lack of clinical data and only very limited traditional support for this specific use.
