Safety, Side Effects and Contraindications

Artemisia annua can be used as a medicinal plant for its antimalarial properties, particularly due to its active compound artemisinin.

However, it may cause side effects such as gastrointestinal upset, headache, dizziness, and in some cases, allergic reactions. It should not be used during pregnancy or breastfeeding due to potential risks to fetal or infant development, and it is contraindicated in individuals with a history of seizures or certain blood disorders. Artemisia annua may interact with anticoagulant medications, increasing the risk of bleeding, and should be avoided with other herbal supplements that have blood-thinning effects.

For safe use, it is recommended to consult a healthcare professional before use, follow recommended dosages, and monitor for any adverse reactions.

Growing, Harvesting and Storage

Artemisia annua grows best in well-drained, loamy soil with a pH between 6.

0 and 7. 5, in full sun to partial shade, and requires consistent moisture during the growing season. It thrives in temperate climates and should be planted in spring after the last frost, with seeds sown directly into the soil or started indoors and transplanted later. Regular watering is essential, especially during dry periods, but the plant should not be overwatered to avoid root rot. For optimal yield, it is important to weed regularly and apply a balanced fertilizer every few weeks to promote healthy growth. Harvesting should occur when the plant is in full bloom, typically in late summer to early autumn, using scissors or shears to cut the top portion of the plant, ensuring not to damage the stems.

After harvesting, the leaves and flowers should be dried in a cool, dark, and well-ventilated area to preserve potency, and stored in airtight containers in a cool, dry place or refrigerated to extend shelf life.
