The record of the place of origin of Artemisia argyi was first found in the monograph of herbal medicine in the Liang Dynasty, Bielu of Famous Doctors: "Born in the Wild". There is no specific explanation. In the Song Dynasty, Su Song's "Illustration and Materia Medica" recorded: "Leaves are everywhere today, and those who restore Taoism and have four bright ideas are the best." According to the book, Fu Dao and Siming Ai are the best.

According to textual research, Fudao is under the jurisdiction of today's tangyin county, Anyang City, Henan Province, that is, today's Fudao. There is a saying in Li Shizhen's Compendium of Materia Medica: "Tang Yin is called Bei Ai".

2. Hai Ai:

Artemisia argyi is wormwood in Ningbo, Zhejiang and its nearby areas today.

In the Song Dynasty, Su Song's "Illustration and Materia Medica" recorded: "Leaves are everywhere today, and those who restore Taoism and have four bright ideas are the best." Siming here is today's Ningbo area.

"Compendium of Materia Medica" records: "Four-Ming people call it Hai Ai"

Xiaoxiang Yiye searched the literature and found nothing. Only a passage was found in Mei Quanxi's book Research and Application of Folium Artemisiae Argyi. Professor Mei Quanxi wrote to Hu Shuangfeng of Ningbo Institute for Drug Control when he was doing research on Artemisia argyi leaves, requesting to collect samples of Artemisia argyi leaves on his behalf. As a result, Hu told him that "Artemisia argyi leaves have not been produced in Ningbo for a long time, and all the Artemisia argyi leaves used were imported from other places". From this point of view, the ancient name Ai-Hai Ai has already withdrawn from the historical stage.

3. Artemisia argyi:

In the Ming Dynasty, Artemisia argyi made her debut.

The Compendium of Materia Medica, which was finalized during the reign of Hongzhi in Ming Dynasty, records: "Born in the field, there are authentic places everywhere today: Chaozhou and Mingzhou." Qizhou is today's Qichun in Hubei, and Mingzhou is today's Ningbo in Zhejiang and its nearby areas.

Later, Herbal Mengsheng included a picture of "Aiye in Qizhou", and recorded: "If you have a collection, you can buy it at a generous price, and every time you choose it, you will be given it away from Beijing and wrapped in paper to show your preciousness, and your name will spread far and wide, and you will be heard everywhere."

In Compendium of Materia Medica, Li Shizhen put forward the name of "Artemisia argyi" for the first time. The book wrote: "Since its inception, people in Qizhou have won, filled the square with things, and the world is heavy, which is called Ai Ai. "From then on, Artemisia argyi ranks among the famous Ai in China.

Doctors in the Ming and Qing Dynasties all attached importance to and respected the mugwort. In the Ming Dynasty, "Herbal Medicine is half elegant" recorded that "(Artemisia argyi leaves) were born in valleys and fields, and those in Qizhou were the most expensive, and those in Siming were also the best". The book also said, "Qi Zhou Gong Ai Ye, with nine sharp leaves, is five or seven inches long and about one minute thick, so it can be called Mei Ai.

4. Qi Ai:

Qi Ai and Yan Ai are homophonic, but they are two different places of origin.

Qi 'ai is an excellent variety of Artemisia argyi, which appeared at the beginning of last century. It refers to Artemisia argyi produced in Anguo, Hebei Province (formerly known as Qizhou). Qizhou is located in the center of the north, rich in medicinal materials, and is a distribution center for northern medicinal materials. Since the Qing Dynasty, the reputation of Qi Ai has gradually spread and become one of the main varieties of Qi Medicine.

There are also records of the application of Qi 'ai in the medical records of Qing officials, and there are also records in the "products" of Qi Zhou Zhi in Qing Dynasty. However, its application is not as good as that of Artemisia argyi. According to statistics, in the prescription of medical records in Qing Dynasty, the frequency ratio of the use of Artemisia argyi and Artemisia argyi is about10: 3. The Institute of Traditional Chinese Medicine of China Academy of Traditional Chinese Medicine has made a comparative study on the characteristics of Artemisia argyi from Anguo, Hebei Province and Artemisia argyi from Qichun, Hubei Province. The results show that "Qi Ai" is superior in some aspects.

Li Ruzhen, a novelist in the Qing Dynasty, wrote the prescription in The Mirror Flower Garden in his later years. He used Qi Moxibustion for three times to cure warts (paralysis) and never relapse. The book Jing Hua Yuan was written in the 23rd year of Jiaqing in Qing Dynasty (1878), long before the Opium War. The appearance of "Qi Ai" in the book confirms the historical fact that Qi Ai was already used by doctors as a Chinese herbal medicine at that time.
