Artemisinin is the product extracted from the dry leaves of artemsisia annua (sweet wormwood). This plant has to be grown each year stating from seeds. The plant is peculiar in its behaviour. Nicely grown-up plants may be devoid of artemisinin. In order that this product is synthetised by the plant special agricultural conditions must be respected. The plant can grown in many places but it may not contain artemisinin.
For example: Visitors of the ancient palaces in the forbidden city in beijing can find nice artemisia annua plants pushing left and right as weeds, but these plants do not contain artemisinin.
Best results have been obtained in plantations (north Vietnam, mainly in the vicinity of hanoi) or in wild plants (the plants collected from the steep hills around you young in the Chongqing province in China where the plant grows at altitudes above 1400 m).
Artemsia annua is a plant with a strong parfum. It contains camphor and essential oils. It is a strong plant. Once it has started on its full development it can survive a hot climate and long dry spells. The roots penetrate very deep. The plant needs to be harvested before the flowering starts since this decreases the content of artemisinin. In optimal conditions 1 hectare will yield 1-2 tons of artemisia leaves. Every ton gives 2-3 KG artemisinin. Wild plants, as grown in Central China give similar results but others do not and some do not even have artemsinin inside.
