In Qichun, Hubei Province, the hometown of Li Shizhen, the author of Compendium of Materia Medica, Artemisia argyi was listed as one of the "Four Treasures of Qichun".

In addition to the above oral and external effects, Artemisia argyi also has a special usage-moxibustion. Moxibustion is a kind of therapy that moxa or moxa powder is made into cone or cake and then smoked, and then directly or indirectly moxibustion is applied to the human body surface through ginger slices and garlic slices in different ways. The origin of moxibustion can be traced back to ancient times. According to legend, when the ancients used tortoise shells for divination, they made ice into a convex lens to light a fire, and wormwood leaves were used to light a fire. When people see the cracks in the tortoise shell, they are connected with human blood, which further improves the prevention and treatment of diseases. The Zhuangzi records that "the Yue people smoked it with moxa" and Confucius described "self-moxibustion without illness", all of which illustrate the health care function of moxibustion. Moxibustion usually involves removing the tendons (i.e. veins) of mugwort leaves, mashing cotton-like mugwort leaves and rolling them into moxa sticks. There are also some methods to add medicinal powders such as musk, frankincense, myrrh and radix aucklandiae into folium Artemisiae Argyi to make medicinal moxa sticks. In addition to the methods mentioned above, there are also salt-separated moxibustion and aconite cake-separated moxibustion. Moxibustion techniques include mild moxibustion in which moxa sticks are directly smoked at the moxibustion site, bird-pecking moxibustion in which birds peck together, rotary moxibustion in which moxa is wrapped around needles, and moxibustion with moxibustion devices such as moxibustion box. Its mechanism of action is that the efficacy of wormwood and other drugs combined with the heat energy generated by moxibustion fire can stimulate the body to achieve the purpose of treatment. The following briefly introduces several moxibustion therapies with health care and therapeutic effects.

● Health Moxibustion Moxibustion Zusanli (three inches below the knee on the front and lateral side of the calf and one finger on the lateral side of the tibia), Qihai (one and a half inches below the navel) and Guanyuan (three inches below the navel).

Doing this moxibustion often can improve the immune function of the human body, enhance the resistance and make the body comfortable.

The moxibustion time of each acupoint is about 10 minute. Can be used for treating epigastric pain caused by acute and chronic gastritis, gastric and duodenal ulcer, neurosis, etc. This moxibustion method can regulate the peristalsis of the stomach, thus playing a role in relieving pain. In addition, 3 ~ 5g of Folium Artemisiae Argyi can be soaked in water instead of tea, or 1 ~ 2 Folium Artemisiae Argyi can be kneaded and swallowed to treat epigastric pain caused by cold pathogen.
