Information @ a Glance


  • Artemisia is a large, diverse genus of plants with about 180 species belonging to the daisy family (Asteraceae).
  • They grow in temperate climates of the Northern Hemisphere, usually in dry or semi-dry habitats.
  • It contains many well known species, such as Roman wormwood, Sagebrush, Tarragon, Mugwort, and Southernwood.
  • ARTEMISIA annua (known as ‘quinghao’ in China) is an aromatic annual herb endemic to the northern parts of Chahar and Suiyuan provinces in China.

Cultivation & Harvesting

  • WHO is working with partners to stimulate local production and extraction of artemisinin from Artemisia annua in Kenya and Tanzania.
  • Higher artemisinin content well before flower bud formation was not expected and a further examination of seasonal changes in artemisinin accumulation is needed.
  • To investigate the possible effect of water stress on the accumulation of artemisinin, four different water stress treatments were investigated.
  • The amorphane sesquiterpene artemisinin is naturally formed in the shoot of Artemisia annua plant

Application & Technology

  • Artemisia species, growing in almost all the northern hemisphere, is used in folk medicine of some countries as a remedy for hypertension.
  • An alkaloid of Artemisia which was metabolized to small molecules in digestive tract and then could pass through the blood-brain barrier, appeared to be an acetylcholinesterase inhibitor with a blocker of neurotoxicity induced by beta amyloid in human brain causing Alzheimer’s disease
  • Postharvest handling of artemisia plants could affect artemisinin content, six drying techniques over different time periods were examined to identify the best drying method. Drying method and duration had highly significant effects on leaf moisture.


  • Armenia is a small mountainous country on the Armenian Plateau in the South of the Caucasus between the Black and Caspian Seas. Owing to anthropogenic influence the sources of some medicinal plants (especially growing on disturbed lands - Tussilago farfara, Urtica dioica, and Artemisia absinthium) have recently increased in Armenia.
  • All the production of aromatic plants including Artemisia in Israel is done in greenhouses to ensure the production of high quality products year round. Heating, cooling and supplementary light may be employed according to the season and the crop needs.
