Prickly Ash

HARVESTING

Berries are harvested in late summer. Bark is harvested in the spring. The bark is a stronger stimulant, and most of what I found refers to using the bark. The berries contain the essential oils, however.

I’ll be hunting my property for prickly ash this year! 

In my studies, one reference says that Prickly Ash is similar to cayenne, only it works slower.
