Interesting Facts

This tree contains a natural topical numbing agent (hence its common names "Tickle Tongue" and "Toothache Tree").  It is said that pioneers would chew the bark and leaves of this tree to ease toothache pain.  Leaves are said to smell like "toothache drops."  Fruit has  a lemon zest taste and numbs the mouth, similar to Szechuan peppers (both plants are from the Zanthoxylum genus).  Bark and branches can be very spiny; not a good choice to plant along bike paths or where children play.  Is larval host plant of the Giant Swallowtail butterfly.  Note: This plant is often confused with Aralia spinosa, but they are two distinct species.
