Betulin, a non-bioactive precursor of betulinic acid, is also found in the bark of the Betula alba (white birch) tree at concentrations of up to 25%. The tree is fast-growing and abundant in North America and Europe. The raw material is readily available in large quantities since birch bark is considered a waste product in the pulp and paper, and furniture manufacturing industries.
