Jiyuan wintergrass is mainly distributed in the mountainous area of ​​800~1200 meters in the north of Jiyuan City. The climate here is mild, the rainfall is abundant, the light conditions are good, and it is very beneficial to the growth of iced grass, with a reserve of more than 1,200 tons. Shape characteristics Jiyuan ice ridge sketch (2) In the winter morning, when the temperature drops below 0 °C, the contents of the source of the sage and the surface water vapor condense on the stem into paper-like borneol, curled into various patterns, look far Like the tidbits, it is very elegant, and Chinese herbal botanists, in order to accurately represent this feature, hence the name Icicle. This genus is a genus of the genus Lamiaceae, a perennial herb or subshrub plant, 30 to 100 cm high, with a cylindrical base, an upper quadrilateral shape, a developed stalk, densely velvety, leafy or oval.

It is based on the whole plant in the upper part of the plant, and the best effect is the leaf. The medicinal value of Jiyuan Donglingcao was first discovered in Jiyuan City, Henan Medical Science Research Institute. Prior to this, there was no record in the Compendium of Materia Medica. After the Institute of Botany, Chinese Academy of Sciences, Henan Medical University, Henan Medical Science Research Institute, A variety of research conducted by the Henan Institute of Biological Sciences fully affirmed its anti-tumor, plant antibacterial, anti-cancer treatment and improved taste, and was included in the Pharmacopoeia of the People's Republic of China in 1977. Because Jiyuan Icegrass belongs to the genus Camellia, the new variant of the broken Mia, the anti-tumor active ingredient--the ice-saling A and B are significantly higher than other producing areas, and the "Chinese native products" is also listed as Jiyuan. specialty. Among them, ice stalk A and B are anti-tumor active ingredients, have obvious bactericidal effects, and have certain curative effects on various cancer diseases, especially in early esophageal cancer. In addition, it has a strong killing effect on upper respiratory tract strains such as Staphylococcus aureus and Streptococcus aureus. It has been widely used in the clinical treatment of pharyngitis, tonsillitis and stomatitis, and is known as u0026quot;Pencillin in Chinese medicineu0026quot; ; The research on variety characteristics proves that the population of Jiyuan wintergrass is unique and the quality is authentic, and its content of A is 50% higher than that of similar products in other places. Jiyuan Rubescens is rich in a variety of effective active ingredients. Through many years of research by the Kunming Institute of Botany of the Chinese Academy of Sciences and the Henan University of Traditional Chinese Medicine, the fingerprints of HPLC in the Jiyuan City are completely different from those of other local weeds, and the active ingredients are rich. High content, unique population and authentic quality. The content of Rubescensine in Jiyuan wintergrass is ≥0.5%, rosmarinic acid is ≥0.8%, and water-soluble extract is ≥30.0%. In particular, the content of A. sinensis is the highest, which is 50% higher than the other production of Rubescensine A.
