What is the effect of wormwood in May? Thank you, everyone.
Folium Artemisiae Argyi is a perennial herb of Compositae, which is distributed all over the country, especially in qi zhou, Hubei. May of the lunar calendar is the time when mugwort leaves grow most vigorously and have the highest oil content, so ordinary mugwort leaf collectors will not miss this best season. Li Shizhen also had an incisive exposition on the efficacy of mugwort leaves: "mugwort leaves are slightly bitter and too bitter when they are born, and slightly bitter and too bitter when they are ripe. Raw temperature and cooked heat are pure yang. You can take the real fire from the sun and go back to Yuanyang. If you take it, it will pass through the three yin, drive away all cold and dampness, and turn the cold into one. Moxibustion penetrates the meridians, causing all kinds of diseases and evils. The person who is addicted is Kangtai, and his merits are also great. " There are numerous medical uses of mugwort leaf. Decocting Folium Artemisiae Argyi has a good effect on gynecological diseases such as functional uterine bleeding, dysmenorrhea and irregular menstruation. External washing of decoction can treat eczema and itching of skin; Folium Artemisiae Argyi is mashed into velvet and made into moxa sticks or cakes, which can be used for moxibustion in traditional Chinese medicine. Aifu Pill and Jiaoai Decoction, mainly composed of Folium Artemisiae Argyi, have always been commonly used prescriptions in gynecology. Among them, Folium Artemisiae Argyi has the function of warming meridians and dispelling cold. Therefore, Li Shizhen once spoke highly of it: "Aifu Pill is quite effective in treating heart and abdomen pain and recuperating gynecological diseases. Jiao Tang Ai is particularly effective in treating asthenic dysentery and postpartum hemorrhage. Tablets or injections made from Folium Artemisiae Argyi have certain curative effects on gastric cancer, lymphosarcoma, hepatitis and other diseases. Pharmacological studies have confirmed that Folium Artemisiae Argyi oil has antagonistic effect on various allergic asthma, and has obvious antiasthmatic, antitussive and expectorant effects. Its antiasthmatic effect is similar to isoprenaline, and it can be used for respiratory diseases such as chronic bronchitis, emphysema and bronchial asthma. In addition, mugwort oil is a good perfume oil with strong fragrance and cool feeling, so it has become a component of some cosmetics. There is a traditional custom among the people in our country: during the Dragon Boat Festival, every household should hang moxa sticks, boil mugwort leaves for bathing or spray the corner of the courtyard, burn mugwort fire and smoke the house. This is a hygienic habit with scientific reasons. With the warming of the climate in May, mosquitoes multiply in large numbers, and the effective component (Artemisia argyi oil) contained in Artemisia argyi leaves has a strong bactericidal and insecticidal effect. Its fumigant can not only inhibit and kill most indoor germs, but also kill mosquitoes, maggots and fleas, which is harmless to people and animals. On the Dragon Boat Festival, the grass grows thick and the wild wormwood is soft and fragrant. I don't mean to be coquettish, but my name is known to the people. May its ugly mugwort leaves bring people health forever.
