What is the primary medical use of Artemisia annua?

The primary medical use of Artemisia annua is to treat malaria. This plant contains artemisinin, the key antimalarial compound discovered in the 1970s by Tu Youyou. Artemisinin and its derivatives are central to modern therapy, especially for Plasmodium falciparum, including strains resistant to other drugs. Because the compound acts quickly but has a short half-life, it’s given in combination with another antimalarial (artemisinin-based combination therapy, or ACT) to boost efficacy and reduce resistance. The way it works is by being activated in the parasite's heme/iron-rich environment, producing reactive radicals that damage parasite proteins and membranes, leading to rapid parasite death. While Artemisia annua has historical use for fever or malaria-like symptoms, today its primary medical role is antimalarial treatment. It is not a standard treatment for diabetes, hypertension, or insomnia.
