[4][5][6][7], Artemisia annua belongs to the plant family of Asteraceae and is an annual short-day plant. It has been suggested that the important part here is the “wringing” step, which might cause the release of various oily compounds from the plant which form an emulsion and help to extract the artemisinin. A. annua is a slow-growing wind-pollinated plant, native to temperate Asia and Eastern Europe, and is now also naturalized in North America (Woerdenbag & Pras 2002). Expert review of anti-infective therapy, 7(8), pp.999–1013. Records of the herb’s medicinal use stretch back over 2000 years (Laughlin, Heazlewood & Beattie 2002; Mucciarelli & Maffei 2002).

Familiar members of the genus include wormwood (A. absinthum L., notorious for its use in the spirit absinthe), the culinary herb tarragon (A. dracunculus L.), and mugwort (which may refer to A. vulgaris or many other Artemisia species, used either as a food or medicine in many parts of Eurasia). The compound was given the Chinese name Qing Hao Su, meaning “a principle from Qing Hao” (Youyou 2011). 2016]. 2016]. Mueller, M. S., Karhagomba, I. This works because any given malaria parasite is unlikely to possess resistance to both types of drugs. Practitioners of TCM classify herbs in terms of four properties: hot, warm, cool and cold, and five tastes: sour, bitter, sweet, pungent and salty. The same can be said of A. annua L., whose oil, described as “grassy, fresh, and bitter with a camphoraceous nuance”, has uses in the cosmetics and perfumery industries, and has been reported to have antifungal and antibacterial properties (Woerdenbag & Pras 2002).

In other words, the best form extraction is one in cold water. Chamomile: food, medicine or something in between? It is a fast-growing, giant annual with upright, often red stems and bright green, pinnately divided, saw-toothed leaves. However, since artemisinin is quite a complex molecule it is difficult to design a process which is efficient enough to compete with simply growing the plant. Another high-tech approach obviates the need to grow the plant at all. [17], In traditional Chinese medicine (TCM), A. annua is traditionally used to treat fever. In Traditional Chinese Medicine (TCM), A. annua is known as Qing Hao (literally “blue-green herb”) (Laughlin, Heazlewood & Beattie 2002) and is included in the official Pharmacopoeia of the People’s Republic of China. [16] Besides few viral diseases Artemisia a. has no major diseases that need to be controlled. The extracts prepared in this manner displayed exceptional antimalarial activity, with almost 100% efficacy in killing malaria parasites in mice and monkeys (Youyou 2004; Cui & Su 2009; Awofeso 2011). By 1971, the researchers had carried out a series of experiments on A. annua but had not obtained any particularly encouraging results (Hsu 2006). annual wormwood. Yu, H. and Zhong, S., 2002.

The idea is that instead of extracting the active compound artemisinin and formulating it into a pharmaceutical drug with all the expenses that would entail, a crude preparation (such as a tea or juice) could be used. (Wormwoods) are often herbaceous biennials or woody perennials with hairy foliage (at least on the underside of their leaves). Binomial name; Artemisia annua. London: Taylor & Francis, pp.149-158. To avoid gambling the supply of artemisinin on the vagaries of Nature, several other approaches for the production of artemisinin-type drugs have been devised. © Joe Barnett, MSc student (2015 – 2016), Research Cluster ‘Biodiversity and Medicines’ / Centre for Pharmacognosy and Phytotherapy,  UCL School of Pharmacy, Univ.

For the song, see, Pharmacopoeia of the People's Republic of China, Flora of China Vol. London: Taylor & Francis, pp.159-198, Mucciarelli, M. and Maffei, M., 2002. Artemisia annua L. Sweet wormwood is an annual, aromatic herb from Asia, and has been used in China to treat fevers for more than 2,000 years. It is the fruits of Artemisia Annua plant. One problem shared by many plant-derived drugs is variability in the content of the active compound. Artemisia annua is also known by the names absinthium, annual wormwood, sweet wormwood, Sweet Annie and Qing Hao. The pharmaceutical company Sanofi has now started producing artemisinin in this manner, operating under a “no profit, no loss” scheme (Amyris 2013). As mentioned above, the use of artemisinin-type drugs alone is not recommended since it selects out malaria parasites that are resistant to artemisinin and in the long-run will cause an increase in artemisinin-resistant malaria. This is due to a few different factors, namely the short half-life of artemisinin within the patient, the small amounts of artemisinin in the tea, and the fact that artemisinin cannot kill all the malaria parasites within the patient, only the ones at certain stages of their life-cycle (Mueller et al. The leaves of A. annua have a length of 3–5 cm and are divided by deep cuts into two or three small leaflets. and Newman, J.D., 2013. Journal of Ethnopharmacology, 120(3), pp.302–314.

Its stem is erect brownish or violet brown. It has been suggested that A. annua could be used as a self-reliant treatment in Africa (de Ridder et al. Therefore, one possible strategy is to extract the artemisinic acid from the plant and chemically convert it to artemisinin (Laughlin, Heazlewood & Beattie 2002). The Lancet, 380(9840), pp.507–535. Annual Wormwood is a non-woody summer annual that has hairless foliage with a sweet fruity fragrance. The plant should be harvested at the beginning of flowering. In: C. Wright, ed., Artemisia, 1st ed. While this breakthrough promises to lower the price and stabilize the supply of artemisinin, it has been argued (Thomas 2013) that the new technology represents an assault on the livelihoods of A. annua farmers, and that sufficient artemisinin can be produced from botanical sources alone. At that time the artemisinin content is the highest. Common names: Sweet Annie ... Artemisia annua often persists in gardens, becoming naturalized in moist-temperate areas (especially in eastern United States). The genus Artemisia belongs to the Compositae (daisy and sunflower family) and includes well-known plants used in medicine, perfumery and the food and drink industry, such as A. dracunculus (tarragon), A. absinthium (absinthe) and A. vulgaris (mugwort). Obtained from the sweet wormwood plant, Artemesia annua, artemisinin was first discovered in the 1970s. Re-imagining malaria – a platform for reflections to widen horizons in malaria control.

Hence it is important that antimalarial drugs can be provided at low cost. Reports of naturalization may be exaggerated (reported for Prince Edward Island, but not established). It is in flower from August to September, and the seeds ripen from September to October. In a collaborative effort of Chinese researchers, the active compound was eventually isolated and in 1975 its structure was elucidated. White Mugwort (Artemisia lactiflora) White Mugwort is a Chinese native plant that has erect, yellow … In fact, in 2006, the WHO called for pharmaceutical companies to stop producing drugs that contain only artemisinin-type drugs, in favour of combination drugs (WHO 2006). 2013). These categories are related to the concepts of Yin and Yang. sweet annie. can still cause variations in artemisinin levels (Delabays, Darbellay & Galland 2002). [27], Even though the beneficial effect of these phenolic compounds on a great number of diseases is often discussed, different studies show beneficial effects of flavonoids compound produced by A. annua.

[36], Despite global efforts in combating malaria, it remains a large burden for the population, particularly in tropical and subtropical regions. 2016]. In the plant itself, artemisinin is made from a closely related chemical called artemisinic acid. Other compounds may also have a synergistic antimalarial effect when combined with artemisinin (Hsu 2006). 2008). In order to prevent or at least slow down the development of resistance, artemisinin-type drugs are usually used in combination with other types of antimalarials, which ensures that the malaria parasites are completely eliminated.

It is recommended to sow 1.4 – 2 seeds per square meter. [22] In 2015 artemisinin was shown to bind to a large number targets suggesting that it acts in a promiscuous manner. The plant itself is hairless and naturally grows from 30 to 100 cm tall, although in cultivation it is possible for plants to reach a height of 200 cm. Sweet wormwood has a sweet scent. These details suggested that the active compound might be easily decomposed by heat. [37] Resistance will likely spread to other endemic areas across the world. [27], Flavonoids are generally known for their redox properties involved in the delay or inhibition of the initiation or propagation in oxidizing chain reactions. … In … [27], Research to develop antimalarial drugs led to the discovery of artemisinin, a compound which is extracted from Artemisia annua, in the 1970s by Chinese scientist Tu Youyou, for which she shared the 2015 Nobel Prize in Physiology or Medicine.

[10] The small flowers have a diameter of 2–2.5 mm and are arranged in loose panicles. A lesson learnt: the rise and fall of Lariam and Halfan. Despite that, recent studies show that the flavonoids present in the A. annua leaf are linked to suppression of CYP450 enzymes responsible for altering the absorption and metabolism of artemisinin in the body. There is no reason to believe that this rule should not apply to these teas as much as it applies to pure pharmaceutical drugs. It is now grown commercially in many African countries. de Ridder, S., van der Kooy, F. and Verpoorte, R., 2008. [26], Artemisia annua possesses the capacity to produce high phenolic compounds, which result in high antioxidant activity. [8][11], The growing period of Artemisia annua from seeding till harvest is 190–240 days, depending on the climate and altitude of the production area. One approach is “total synthesis” i.e. Purification processes were used to isolate the active molecule, and clinical trials showed the active ingredient to be an effective drug. Tu Youyou recognised the significance of Ge Hong’s specification of fresh (as opposed to dry) herb, and the use of low temperatures. Artemisinin has a unique type of structure including a particularly unusual feature called an endoperoxide group, which has been found to be essential to its antimalarial activity.
