Purple Giant Hyssop

Like other members of the mint family, the purple
giant hyssop contains essential oils that provide
aromatic and medicinal services. Infusion of the root
was used by the Meskwaki (a Great-Lakes region
tribe) as a diuretic. There is also interest in Agastache
for its flavonoid compounds. However, in the eastern
United States species of A. scrophulariifolia the
number of compounds is greatly reduced compared to
the western species of Agastache.
