Has been used historically in the treatment of congestion, gas, headache, liver, stomatitis, lower blood pressure, headache, constipation, and for menopause.

In many places, it is considered a pest weed that grows in vacant lots and on roadsides, but the indigenous populations have often had a different use for the noxious weed.
