Also known as Toothache Tree, it is cultivated in Canada and Northern America. 

Northern Prickly Ash Bark occurs in curved or quilled fragments externally brownish-grey. It is used both internally and externally to treat rheumatism and toothache, for fevers and as a tonic, and for circulatory insufficiency. 

It can also be used as an analgesic, diaphoretic, carminative and anti-diarhoeal.
