American prickly-ash
Zanthoxylum americanum
Zanthoxylum americanum, commonly known as American prickly ash, is a traditional medicine plant native to North America. While its specific uses in traditional medicine are not well-documented, it has been studied for its biological activities. Scientific evidence suggests that extracts from red and yellow species of Zanthoxylum use different strategies during autumn senescence, with red species relying more on anthocyanins. Research indicates that furanocoumarin content in Zanthoxylum americanum shows broad antifungal activity against various fungal strains. Additionally, the study found that these furanocoumarins inhibit DNA polymerization, though the specificity of this inhibition varies depending on base composition. Other plants like Arctostaphylos uva-ursi, Hydrastis canadensis, and Prunus serotina have also shown varying levels of activity against Neisseria gonorrhoeae isolates, but no specific evidence is available for Zanthoxylum americanum in this context. To date, there are no major safety concerns or recorded drug interactions associated with the use of Zanthoxylum americanum.
