Its leaves are papery or thin papery, green on the front, glabrous or nearly glabrous, and densely covered with gray-white spider silky flat wool on the back.

In many places, folk people take the whole herb of Artemisia annua for hemostasis, anti-inflammatory, antitussive, phlegm, and even directly pick young stems and leaves for fresh vegetables or pickled vegetables.
