Isatis tinctoria is a flowering plant from the mustard family that grows about 2-4 feet tall and has a root system with a thick taproot that can plunge more than 5 feet in depth. To create the commercial product, the roots are soaked in alcohol to promote the release of the beneficial materials. Then the alcohol is vacuumed out, the remaining liquid is filtered to eliminate impurities, and its dried to create an extract powder. (Historical texts cite this method, but back in the day, people soaked the herbs or flowers in wine!)

While its native to Europe and Asia, if you live in Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, or Wyoming, youve likely seen it growing in roadside ditches and open rangelands especially in late spring when its bright yellow flowers are in bloom. Isatis tinctoria was introduced to North America when some of the first settlers from Europe came over in the 1600s. Now, it can be found across the continent, but its especially pervasive in the states listed above, where its considered a noxious weed.
