Medicinal pharmacology can dispel wind and remove dampness, expel pus and promote granulation to relieve pain; Indications: wind-cold common cold, forehead headache, sinusitis, toothache, hemorrhoid core leakage, hematochezia, leucorrhea, carbuncle swelling, burn and other symptoms. Radix Angelicae Dahuricae decoction 1: 10 has inhibitory effects on Escherichia coli, Sonne's dysentery, typhoid fever, paratyphoid fever and cholera. It has inhibitory effect on artificial tuberculosis. The water extract also has a certain inhibitory effect on pathogenic fungi such as Microcystis. Production environment Suining production area is located in the middle of Sichuan basin, and Fujiang River flows vertically. The sandy soil and oily sandy soil weathered by grayish brown alluvial deposits in Fujiang and the local subtropical humid monsoon climate zone form a special ecological environment from Suining osmanthus to Longfeng coast, and its soil and climate are very suitable for the growth of Angelica dahurica. Suining has simple geological structure and gentle folds. The landform type is single, belonging to the eroded hilly landform formed by the erosion, cutting and accumulation of flowing water in Mesozoic and Jurassic strata. Hills account for about 70% of the city's total area, valleys and terraces account for 25%, low mountains account for 5%, and the altitude is between 300 and 600 meters. The lower part of the whole rock is mainly limestone, and the upper part is mainly purple sand and mudstone. Therefore, Suining area is also called "red land". The historical origin of Angelica dahurica is Suining, Sichuan. In the Ming Dynasty (1368 ~ 1644), Angelica dahurica was introduced and cultivated in Hangzhou, forming an authentic medicinal material. In 2004, Wang confirmed that Anyue, Nanchong and other places in Sichuan introduced Angelica dahurica from Suining in 1956, 1958 and 1966, respectively, and became the main producing areas of Angelica dahurica in Sichuan. Production situation Suining, known as the hometown of Angelica dahurica in China, is an authentic producing area of Angelica dahurica in Sichuan. With a traditional cultivation history, the products are sold to China, Hongkong, Japan, Southeast Asia, Europe and America. By 2008, the output of angelica dahurica will be 3000 ~ 4000 tons. In June, 2006, the GAP base of Angelica dahurica was certified by the US Food and Drug Administration. Product Honor of Angelica dahurica in 2006, the "GAP of Angelica dahurica" project passed the national certification, and it is a nationally certified production base of Angelica dahurica. Its scientific and technological achievements rank at the international advanced level, and the project achievements won the first prize of provincial scientific and technological progress.
