Fuyang is the most important production base of Artemisia annua in the world. Its artemisia production and planting technology has passed the national GAP certification and enjoys the reputation of “the hometown of Artemisia annua”. [1] Artemisia annua is an annual herb of the family Asteraceae, which is unique to China. Artemisinin extracted from Artemisia annua is a special drug for malaria, and is called “a milestone contribution to the conquest of malaria” by the World Health Organization. In 2001, the World Health Organization announced that Artemisia annua L. was the drug of choice for the treatment of malaria. At the same time, it indicated that 34 countries with severe malaria no longer use traditional medicines such as quinine and switch to artemisia preparations. The specific quality and reputation of “Yangyang Artemisia” are directly related to the natural factors or human factors such as water, soil and climate in the area marked by the geographical indication. According to statistics, more than 80% of the raw materials of artemisinin drugs in the world come from Fuyang, because Fuyang is very suitable for the cultivation of Artemisia annua L., and the artemisinin content in Artemisia annua leaves is twice the national average. Background News The reason why Chinese scientist Tu Yu won the 2015 Nobel Prize in Physiology or Medicine was “a discovery of new treatments for malaria” – artemisinin that can significantly reduce mortality in malaria patients. Many people may not know that nearly half of the world's most popular drug for the treatment of malaria is from Fuyang, Chongqing, and 80% of the world's raw materials, Artemisia annua, are produced locally. "Chinese medicine" is a miracle against malaria. The cure rate is 97%. Malaria is a worldwide infectious disease that infects hundreds of millions of people every year and causes millions of deaths. In the 1960s, malaria-causing parasites, the malaria parasites, had developed resistance to the quinines commonly used at the time, with serious effects. In 1967, the Chinese government launched the “523 Project” to find new antimalarial drugs with new structures and overcoming drug resistance. It is understood that artemisinin and its derivatives artesunate and artemether can quickly eliminate the malaria parasite in human body and have a good therapeutic effect on falciparum malaria such as cerebral malaria. Artemisinin drugs can be taken orally, by intramuscular injection or intravenous injection, or even as a suppository, which is simple and convenient to use. However, in order to prevent the resistance of Plasmodium to artemisinin, compound therapy of artemisinin in combination with other drugs is currently widely used. As a "Chinese herbal medicine", artemisinin has shown great effects in fighting malaria around the world. In May 2004, WHO officially listed artemisinin-based drugs as the drug of choice for the treatment of malaria. According to statistics from the British authoritative medical journal Lancet, the cure rate of artemisinin combination drugs for falciparum malaria reached 97%. According to this, WHO requested the purchase and distribution of 1 million doses of artemisinin compound drugs in the malaria-prone African region, and no longer purchased invalid drugs. Nearly half of artemisinin is from the local area of ​​Chongqing, which is called “the capital of Artemisia annua”. Chongqing Fuyang is the world's most important production base of Artemisia annua. Its artemisia production technology has passed the national GAP certification and enjoys “World Green”. The reputation of Artemisia. Today (6), the reporter contacted the characteristic economic crop station of Shuyang County. The stationmaster Wu Tinghe introduced the status quo of the local artemisia plantation to the reporter. According to Wu Tinghe, Shuyang County began planting Artemisia annua L. from the 1950s and 1960s. The "523" project also discovered the city of Artemisia in Fuyang. By the 1970s, Xiangyang had begun to build factories. Wu Tinghe said that the current planting area of ​​Artemisia annua L. in Xiangyang is about 80,000 mu, 150 kg per mu, and the annual output of artemisinin is more than 60 tons. "At the same time, the content of artemisinin in Fuyang Artemisia is as high as 1,000. Fourteen, more than double the national standard. According to the survey, the annual use of artemisinin market is about 120-150 tons, and the production of artemisinin in Fuyang accounts for nearly half of the demand of the ward.

According to the statistics of the Agricultural Committee of Shuyang County, there were 3 enterprises that developed Artemisia annua in 2014, with an area of ​​75,000 mu and a yield of 7,500 tons. The market price is about 7 yuan, and the output value is 0.7 billion yuan. In 2015, the company developed Artemisia annua. 2, namely Chongqing Huafang Wulingshan Pharmaceutical Co., Ltd. and Ruinan Agriculture Co., Ltd., Chongqing Huafang Wulingshan Pharmaceutical Co., Ltd. developed 40,000 mu of Artemisia annua, and Ruinan Agricultural Co., Ltd. developed 20,000 mu of Artemisia annua, totaling 60,000 mu.
