Commonly known as mugwort, Artemisia vulgaris is a perennial herb that can reach 60-160 cm high, with many thin lateral roots. The branched, purplish brown stems are parallel grooved, wit ascending twigs covered with short hairs. Leaves are papery, pubescent, dark green on the upper surface, and
have various shapes depending on their position on the plant. The leaves near the base are elliptic and oblong, bipinnate (divided two times) deeply even nearly to midrib. The leaves in the middle are elliptic to ovate, 3-10 cm long and 1.5-6 cm wide, pinnate or bipinnate, with four to five lobes that are elliptic lanceolate or linear lanceolate, 3-5 cm long and 1-1.5 cm wide, with more than one tooth on the tip. The leaves near the top are small, also pinnate and lanceolate-lobed, not significantly toothed or even entire. Head inflorescences are oblong, 2.5- 3 mm in diameter, borne densely in a
spike on the branched twigs as well as spreading panicles on the stems. There are seven to ten purple female flowers, with narrow tube-shaped corollas. Bisexual flowers number 8-20, with tube or goblet-shaped corollas, and
