Zanthoxylum spp. (Z. americanum, & Z. clava-herculus)
Prickly Ash
The Prickly Ash tree is native to North America, where the bark of these American trees has been used as medicine for hundreds of years. The genus name, Zanthoxylum, is said to be derived from the Greek words, zanthos and xylum, meaning “yellow wood.” Eastern Native American tribes valued Prickly Ash Bark as a means to stimulate saliva flow. Native Americans went on to share this knowledge with the new colonists. Eclectic physicians in the United States around the nineteenth century continued the traditional uses of Prickly Ash Bark, primarily as a digestive aid and to strengthen the nervous system.
