This article describes the advantages of cultivating wild, unselected Artemisia annua plants.
A molecular variety of great richness
Cultivating traditional wild varieties of the Artemisia annua plant is primarily beneficial due to the great diversity of molecules produced by the variety. Selected plants lose a large part of this diversity because of the choice to favor one molecule, which causes the plant to lose its “molecular factory” character.
To survive in the absence of human intervention, wild Artemisia annua plants naturally produce a wide range of compounds, including polyphenols, flavonoids, and essential oils, in order to defend themselves against predators, fungi, and oxidative stress. This unique and complex chemical cocktail makes the plant more interesting at the molecular level than a selected plant.
Molecular combination
This molecular richness is produced by the biological activity of the wild plant, which thus produces compounds that are potentially:
-
Antioxidant: can help combat cellular aging
-
Antimicrobial and antifungal: studies have shown strong activity against E. coli bacteria and against fungi
-
Antidiabetic and digestive: Artemisia has been traditionally used to regulate blood sugar levels and treat digestive disorders
Furthermore, the plant contains terpenoids, coumarins, vitamins A and E, as well as proteins and minerals (potassium, calcium, magnesium).
Numerous studies have suggested that extracts of the whole Artemisia annua plant result in better effectiveness compared to the use of pure artemisinin; this effect is called the totum effect. Indeed, researchers have found that taking dried leaves improved the effectiveness of the studied treatments, which, according to this study, demonstrates that the other molecules in the plant act by improving the bioavailability and absorption of artemisinin by the human body.
Robust resistance
Comparative studies have shown that wild Artemisia annua plants often resist environmental stresses such as drought or cold better. The plants therefore have a clear advantage in resisting climatic hazards in the environment. This natural state of the variety makes it the ideal candidate for more resilient and optimal cultivation that adapts to many conditions.
Local adaptation
Finally, cultivating local, natural varieties promotes agriculture that is closer to the terroir and more sustainable. The plants are already adapted to the local soil, climate, and diseases. These varieties therefore require less watering and fertilizer to grow optimally, and the cultivation does not depend on patented industrial seeds, which often come from hybrid (F1) strains.
Disadvantage
The disadvantage of these varieties lies in the variability of yields. Indeed, Artemisia annua is a heterozygous plant, which can affect, from one plant to another, its growth and yield.
Conclusion
Wild varieties of Artemisia annua possess greater potential in the plant’s production of active compounds, enabling a synergy of molecules in the use of the plant, particularly in medical research.
