In some rural areas in northern China, a kind of wormwood with yellow flowers can be seen on the hillside. Some places call it stinky wormwood, Artemisia annua, etc., but it is not very common and usually grows on the roadside, wilderness or hillside. This is mainly related to its transmission route, because it only grows through seeds, so that once it is scattered in inappropriate places, it will not grow. There was a time when he was very angry, and it was also because of artemisinin. Now it is gradually fading down mainly because malaria is not a major problem facing mankind.

First, the distinction between Artemisia annua and Artemisia annua L. Artemisia annua was originally an unknown Artemisia annua L., but after Chinese biologist Academician Tu Youyou extracted artemisinin which can treat malaria, she was well known and had been popular for some time. However, it is precisely because of the naming of artemisinin that many people mistakenly think that it is extracted from Artemisia annua, but in fact Artemisia annua does not contain artemisinin. This is also the essential difference between Artemisia annua and Artemisia annua.

Second, Artemisia annua has been put into medicinal Artemisia annua, because of its essential detoxification properties and healing ability to skin diseases, its medicinal value has been valued by people. So at present, the yellow flower has been put into use and produced to fight against human skin diseases and malaria, and Academician Tu Youyou, who was once popular, has gradually faded out of people's sight and devoted himself to scientific research, so there is no need for people to chase Artemisia annua, because it has already made contributions to mankind.

Third, in order to protect the value of Artemisia annua, Artemisia annua once shone brilliantly in medical and medicinal value because of artemisinin, and some people with a heart would pick it in large quantities to reap huge profits, so in order to make it play its due value in medical care instead of becoming a commodity that some people hoard. Some conscience media began to follow up on his absence, so that it gradually faded out of people's sight and returned to its former state. So that it can play its role in medicine. Therefore, it came and left silently, and left its due value, so it is also a good thing that she faded out of people's sight.
