Prickly Ash (commonly referring to species like Zanthoxylum americanum or Zanthoxylum clava-herculis) has a history of use in traditional herbal medicine, particularly among Native American and early North American herbalists, for addressing respiratory congestion and related symptoms. The bark and berries were included in remedies aimed at stimulating circulation, reducing chest congestion, and alleviating coughs. Prickly Ash was traditionally considered a “stimulating” or “warming” herb, believed to promote blood flow and help move mucus from the lungs. Such use was documented in 19th-century Eclectic medicine, where it was often combined with other expectorant herbs in formulas for chest complaints.

However, scientific evidence validating these traditional uses is limited. Modern research into Prickly Ash has focused mainly on its analgesic, anti-inflammatory, and circulatory properties, with few or no clinical studies directly assessing its efficacy for lung congestion. Some phytochemical studies have identified compounds (such as alkaloids and essential oils) that could theoretically influence mucous membranes, but there is no direct clinical evidence for its use in treating lung congestion.

In summary, the use of Prickly Ash for lung congestion is rooted in traditional and historical practices rather than scientific validation. While it remains a part of some herbalist traditions, evidence supporting its effectiveness for this specific condition is weak and primarily anecdotal.
