Synopsis

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

Buckthorn (commonly referring to either Rhamnus cathartica or Rhamnus frangula, also known as alder buckthorn or cascara sagrada) has a long-standing use in traditional herbal medicine, primarily as a laxative. However, some folk medicine traditions have used buckthorn preparations to support the clearing of congestion, especially in the context of mild respiratory complaints or to "purge" the body of excess phlegm. This use is not commonly found in mainstream Western herbalism, but may appear in some older European or eclectic herbal texts, where it was believed that stimulating the bowels could help detoxify the body and indirectly relieve congestion.

From a scientific perspective, there is minimal to no clinical evidence supporting the effectiveness of buckthorn for respiratory congestion. Most research and authoritative herbal references discuss only its laxative properties, attributed to anthraquinone glycosides, and warn about potential side effects with prolonged use. No well-conducted human studies have evaluated buckthorn's impact on nasal, sinus, or chest congestion. Therefore, the rating of 1 reflects that while some traditional uses exist, evidence is sparse, and the primary historical use is as a purgative rather than a direct remedy for congestion. Caution is advised with buckthorn due to potential gastrointestinal irritation and other side effects.
