SORRY, TEMPORARILY OUT OF STOCK This is the inner bark, caefully shaved from the stem after the outer "paper" bark that does not smoke as well is removed. Also called Cancasa (Chanshasha), Red Willow Bark is smoked in the sacred pipe, either by itself or blended with other herbs such as Uva ursi and Mullein leaf. Our Red Willow Bark is hand-picked by a First Nations family in Canada, and is hand-processed with love, respect and prayer.
