The leaves are dark green on top and have a smooth texture, the underside is covered with dense white-tomentose (plant hairs that are flattened and matted) hairs.
The flowers are small and reddish-brown or yellow with a hint of green. This plant blooms from July to October.
Plant Parts Used: Both the aerial parts and the root of mugwort has been used in medicine. The most common, both in Western and Chinese herbal medicine, is to use the leaves.
