“Artemisinin – a gift from traditional Chinese medicine to the world.”
In 2015, Tu Youyou represented the field of traditional Chinese medicine at the Nobel Prize awarding ceremony for the first time, proving to the world the infinite potential of traditional Chinese medicine. After two years of discovery of artemisinin, more than 2,000 prescriptions including internal and external use, plants, animals, and mineral medicines were collected. “. “A grasp of Qinghao, soaked in two liters of water, twist to extract the juice, and take it.” This is the record of Qinghao in the treatment of malaria in the medical book “Elbow Hou Bei Ji Fang” written by the Eastern Jin physician Ge Hong. It is this sentence. Over a thousand years, Tu Youyou was inspired to successfully discover artemisinin.
Chongqing Youyang enjoys the reputation of “the hometown of Artemisia annua in the world”. It is the world’s most important production base of traditional Chinese medicine Artemisia annua, and it is also the enrichment area of high artemisinin content in the world, with an average artemisinin content as high as 8‰. Artemisia annua can now be said to be a blindly popular Chinese medicine. At this time, some netizens said, “Isn’t artemisinin extracted from Artemisia annua? What does it have to do with Artemisia annua? Artemisia annua does not contain artemisinin at all.” To answer this question We have to talk about the past and present life of the traditional Chinese medicine Artemisia annua.
Open the “Chinese Pharmacopoeia”, the traditional Chinese medicine Artemisia annua is the dry aerial part of Artemisia annua L. of the Compositae. Cut when the flowers bloom in autumn, remove the old stems, and dry in the shade. Its aroma is specific, the taste is slightly bitter, and it has the effects of clearing deficiency heat, removing bone steaming, relieving summer heat, cutting malaria, and relieving jaundice. And now the botanical Artemisia caruifolia Buch.-Ham. ex Roxb. Although the effect is similar to the traditional Chinese medicine Artemisia annua, it does not contain artemisinin and has no effect on malaria.
Plant: Artemisia annua L. (the traditional Chinese medicine Artemisia annua)
Plant: Artemisia caruifolia Buch.-Ham. ex Roxb. (non-Chinese medicine Artemisia annua)
Artemisia annua as medicine was first seen in the silk book “Fifty-two Prescriptions for Diseases” unearthed from the Han Tomb No. 3 in Mawangdui. In the Song Dynasty, Shen Kuo mentioned in “Mengxi Bi Tan”: “There are many types of Artemisia annua, such as Artemisia annua, and there are two kinds of them. There are yellow ones and blue ones. .”, “Mengxi Bi Tan” also mentioned: “There are sometimes one or two plants among the Artemisia clumps, which are completely blue in color”, indicating that the yellow ones are more common, which is consistent with the geographical distribution of Artemisia annua almost all over the country now. However, Artemisia annua in botany is scattered in low-altitude, wet riparian sands, valleys, forest edges, roadsides and coastal areas. In the “Compendium of Materia Medica”, Li Shizhen, a famous physician in the Ming Dynasty, for the first time separated the green and yellow of Artemisia annua separately. ‘s origin.
Ge Hong, a physician from the Eastern Jin Dynasty, clearly recorded the anti-malarial effect of Artemisia annua in “Elbow Hou Bei Ji Fang”, and Tu Youyou successfully extracted the anti-malarial ingredient artemisinin from it. The description of Artemisia annua and the shape and smell of Artemisia annua in “Compendium of Materia Medica” are consistent with the present Artemisia annua. At the same time, Artemisia annua has a wider geographical distribution and richer resources and easier to collect, so Artemisia annua should be the main source of ancient Artemisia annua. Some scholars have investigated the medicinal materials of Artemisia annua on the market and found that almost all of them come from Artemisia annua, which also confirms this view.

So why is the name Qinghao not used in botany? The first is that Li Shizhen established Artemisia annua as a separate medicine; the second is that the earliest Japanese scholars put Artemisia annua containing artemisinin under Artemisia annua, which does not contain Artemisia annua when they marked the Latin name of plants for traditional Chinese medicine. The vegetarian Artemisia carvifolia was placed under the item of Artemisia annua, which caused today’s doubts.

Due to various reasons, plants and traditional Chinese medicines often have the same name and different names. I also hope that the general public will consult more Chinese medicine professionals when picking and using Chinese herbal medicines, and only when they use the right medicine can they have a really good curative effect.
