Artemisia annua is the official Latin name for a plant better known by names such as sweet sagewood, sweet wormwood, annual sagebrush, or Chinese wormwood. It is a common type of weed that grows throughout the world. It has recently come into the lime-light for being the type of wormwood from which the anti_malarial drug artemisinin is made. Artemisinin is also known by the Chinese name qinghaosu, and has been used in traditional Chinese medicine since 340s for the treatment of fever.

annua are similarly distributed, with 36% of the total from the upper third of the foliage, 47% from the middle third, and 17% from the lower third, with only trace amounts in the main stem side shoots, and roots.
annua to plant spacing and nitrogen fertilization was evaluated in 1985 and 1986 with three populations established from transplants: high density, 30 cm x 30 cm (111,111 plants/ha); intermediate density, 30 cm x 60 cm (55,555 plants/ha); and low density, 60 cm x 60 cm (27,778 plants/ha).
