Prickly ash (most commonly referring to species such as Zanthoxylum americanum or Zanthoxylum clava-herculis) has a long history of use in traditional herbal medicine, particularly in North America. Native American tribes and later eclectic physicians in the 19th century employed prickly ash bark and berries for various ailments, including as a remedy for congestion, sinus issues, and sore throats. The traditional rationale was that prickly ash acts as a circulatory stimulant and a mild diaphoretic, potentially helping to "open" blocked passages and improve mucous membrane function. However, while some anecdotal evidence and historical texts suggest its use for sinus congestion, modern scientific research specifically validating its efficacy for this purpose is lacking. Laboratory studies have shown that prickly ash contains alkaloids, essential oils, and other compounds with possible anti-inflammatory and mild analgesic properties, but these findings have not been directly linked to clinical effects on sinus congestion. Therefore, its use for sinus congestion is justified by tradition rather than by robust scientific evidence.
