The record of the origin of Artemisia argyi was first found in the herbal monograph Bielu of the Liang Dynasty: "Born in the Wild". There is no specific explanation. In the Song Dynasty, Su Song's "Illustration and Materia Medica" recorded: "Ye is everywhere today, and those who have recovered from the Tao are the best." According to the book, Fu Dao and Siming Love are the best.

According to textual research, Fudao belongs to today's tangyin county, Anyang City, Henan Province, which is today's Fudao. There is a saying in Li Shizhen's Compendium of Materia Medica: "Tang Yin is called Northern Ireland".

2. Hai Ai:

Artemisia argyi is the Artemisia argyi in Ningbo, Zhejiang and its vicinity today.

In the Song Dynasty, Su Song's "Illustration and Materia Medica" recorded: "Ye is everywhere today, and those who have recovered from the Tao are the best." Siming, this is today's Ningbo area.

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

Xiaoxiang Ye Yi searched the literature and found nothing. I only found a passage 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, requesting to collect samples of Artemisia argyi on his behalf. As a result, Hu told him that "Ningbo has long stopped producing mugwort leaves, and all the mugwort leaves used are imported from other places". From this point of view, the ancient name Ai Hai Ai has long since withdrawn from the historical stage.

3. mugwort leaves:

In the Ming Dynasty, mugwort made its debut.

The Compendium of Materia Medica, which was finalized during Hongzhi period in Ming Dynasty, records: "Born in other places, there are authentic places everywhere today: Chaozhou and Mingzhou." Qi zhou is today's Qichun in Hubei, and Mingzhou is today's Ningbo in Zhejiang and its vicinity.

Later, "Materia Medica Germination" included a picture of "Artemisia argyi in qi zhou", and recorded: "If you have a collection, you can buy it at a generous price, and every time you choose it, you must send it out of Beijing and wrap it in paper to show its preciousness. Its name will spread far and wide."

In Compendium of Materia Medica, Li Shizhen first put forward the name of "Artemisia argyi". The book wrote: "Since the beginning of the world, Zhou Qi's people have won, and the world is heavy, which is called mourning." From then on, Artemisia argyi became one of the famous Artemisia argyi in China.

Physicians in Ming and Qing dynasties attached great importance to and respected Artemisia argyi. "Herbal Semielegance" in the Ming Dynasty recorded that "(Artemisia argyi) was born in the valley and field, and Zhou Qi was the most expensive, and he who thought clearly was also the best". The book also said: "There are nine sharp leaves, which are five or seven inches long and about one point thick, so they can be called Mei Ai.

4. Ai Qi:

Ai Qi and Yan Ai are homophonic, but they are two different birthplaces.

Artemisia argyi is an excellent variety of Artemisia argyi, which appeared at the beginning of last century. Refers to Artemisia argyi produced in Anguo, Hebei (formerly known as qi zhou). Qi zhou, located in the middle of the north, is rich in medicinal resources, and is the distribution center of northern medicinal materials. Since the Qing Dynasty, Ai Qi's reputation has gradually spread and become one of the main varieties of Qi medicine.

There are also records of the application of Qiai in the medical books of officials in the Qing Dynasty, and there are also records in the "products" in the Qing Dynasty. But its application is not as good as Artemisia argyi. According to statistics, the frequency of use of Folium Artemisiae Argyi and Radix Artemisiae Argyi in the prescriptions of medical records in Qing Dynasty was about 10: 3. The Institute of Traditional Chinese Medicine of China Academy of Traditional Chinese Medicine conducted a comparative study on the characters of Qi Ai in Anguo, Hebei Province and Qi Ai in Hunchun, Hubei Province. The results show that "Qi Ai" is superior to "Qi Ai" in some aspects.

Li Ruzhen, a novelist in the Qing Dynasty, wrote a prescription in the mirror garden in his later years. He used qi moxibustion for three times and cured the wart (paralysis) without recurrence. Jing Hua Yuan was written in the 23rd year of Jiaqing in Qing Dynasty (1878), long before the Opium War. The appearance of "Ai Qi" in the book confirmed the historical fact that Ai Qi had been used as Chinese herbal medicine by doctors at that time.
