Artemisinin, the primary chemical compound found in artemisia, is a potent anti-parasitic (it kills parasites) that is commonly used for treatment of malaria. Activity is primarily limited to blood parasites; general antibacterial activity is limited. Artemisia is primarily indicated when Babesia is suspected as a coinfection in Lyme disease.

Suggested dosage: Depends on the preparation used. Artemisia should not be taken for longer than 7 days. Potency quickly declines with extended use. The dose can be repeated after 3 weeks.

Side effects: Significant risk of neurotoxicity (damage to nervous tissue) with extended use. Never use more than 1-2 months.
