The main component of Rabdosia rubescens health tea is Rabdosia rubescens, also known as ice grass and ice flower, which is a perennial herb or subshrub of Rabdosia in Labiatae. Rabdosia rubescens is a natural anti-cancer and antibacterial plant recently discovered in the valley at the intersection of Taihang Mountain and Hebi Mountain at the end of the 20th century. Because this plant is unique in nature, it condenses into a butterfly-shaped ice sheet as thin as cicada wings from top to bottom in winter, but it does not fall in the sand, which is quite mysterious in the sun. Automatic IACP- 9000 plasma emission spectrum was used by the Natural Resources Comprehensive Investigation Committee of China Academy of Sciences to analyze that Rabdosia rubescens contains 24 trace elements such as iron, calcium, zinc and selenium, more than 7 amino acids such as alanine and aspartic acid/kloc-0, vitamin C, oridonin, flavonoids and other bioactive components. The discovery of extremely high protein content (1 1%) and selenium is an important discovery in the field of Rabdosia rubescens nutrition, thus making Rabdosia rubescens products a daily nutritional treasure for middle-aged and elderly people-Rabdosia rubescens health tea. Rabdosia rubescens health tea is made of Rabdosia rubescens, a selected wild plant growing in the pollution-free Taihang Mountain area, as the main raw material, supplemented by high-quality jasmine, and refined by modern technology. A series of animal experiments have proved that Rabdosia rubescens is safe and reliable, and its pharmacological effects are outstanding. It is a natural plant to treat pharyngitis, stomatitis and other inflammations and conquer cancer in the new century. Study on Anti-cancer Effect of Rabdosia rubescens (Hamst, 732) is a Rabdosia plant in Labiatae. Contains monoterpenes, sesquiterpenes, diterpenes and triterpenes. Experiments have proved that its diterpenoid compound-oridonin is one of the anti-tumor components. Structure of oridonin and oridonin. 【 Function and Use 】 Rabdosia rubescens is used to treat esophageal cancer in China. Experiments show that Rabdosia rubescens water-alcohol extract and Rabdosia rubescens have obvious cytotoxic effects on Hela cells and esophageal squamous cell carcinoma cell line (CaEs- 17) in vitro. It can inhibit a variety of animal transplanted tumors in vivo, such as Ehrlich ascites carcinoma (ascites type and solid), S- 180 (ascites type and solid) liver cancer (ascites type and solid) reticulocyte sarcoma, etc. This product can prevent nitrosamine-induced esophageal epithelial hyperplasia (precancerous lesion) and canceration in rats. It has mild inhibitory effect on humoral immunity and obvious antibacterial effect on various cocci and bacilli. Clinical trials have proved that this product has obvious effects on relieving symptoms, stably shrinking tumors and prolonging patients' lives for esophageal cancer, portal vein cancer, liver cancer and breast cancer. Combined with chemotherapy, it can reduce the adverse reactions of chemotherapy drugs and improve the curative effect, and also has a certain curative effect on severe esophageal epithelial hyperplasia. Has obvious curative effect on acute laryngitis and acute suppurative tonsillitis. It also has a good curative effect on chronic bronchitis and chronic pharyngitis. Analysis of modern pharmacological components of Rabdosia rubescens: Rabdosia rubescens is a common and precious Chinese herbal medicine, which is uniformly distributed. It has antipyretic, anti-inflammatory, sore throat relieving, anticancer and immunity enhancing effects (China Pharmacopoeia 1977 edition). Due to the special geographical location and climatic conditions, wild Rabdosia rubescens in Hebi is not only rich in resources, but also of good quality. Regular drinking helps to enhance the body's own immunity. [Identification of Rabdosia rubescens] 1, the stem is a square column with a length of 30-70cm; The surface is reddish brown and hairy. Leaves opposite, mostly withered or broken. After flattening, it is oval or wide, with a length of 6. 5 13cm, 3-6 cm wide. The margin is coarsely serrated, green or green-brown, with glandular spots on the lower surface, sparsely pilose veins, terminal cymose panicles, and Kobanawa 2-lipped corolla. 2, the gas is slightly fragrant, and the bitterness is sweet. The more leaves, the better the color is green. 4. It is a liquid component [chemical constituents of Rabdosia rubescens] 1, and the volatile oil from stem and leaf is a- pinene, 0.16-1%; Limonene: 0.16%; 1.8 cineole: 0.33%; Paracymene: 0.16%; Non-aldehydes:1.33%; Decaldehyde:1%; β-elemene: 20.23%; Palmitic acid: 6.6%. 2. Diterpenoids: Oridinin, Ponicidin, propanoid, butanone, hexanone, pentabutyl, heptalin, octanol, α-coumarin and five unknown structural components. 3. Roots, stems and leaves still contain trace elements: iron, zinc, manganese, copper, chromium, nickel, cobalt, molybdenum and selenium. [Surface map of lower surface of Rabdosia rubescens leaves (x500)] Cross section of stem (diameter 1mm): epidermal cells are square and small, with tangential width of 5-8um; Non-glandular hairs are numerous, erect or obliquely folded, and consist of 1-3 cells, with a length of 24 pang76 (- 100) um and a basal diameter of 12-20 (-28) um, with obvious verrucous processes on the surface wall. The head diameter of glandular hair is 16-28um, with single cell stalk. There are 5-6 rows of thick keratinocytes and 4-6 rows of cortical cells on four sides, which are slightly tangent to the outside. The parenchyma cells near the pericycle sheath are large and square. The bast fibers are scattered in a single way, and the outer fiber bundles are arranged in a ring-shaped intermittent way; The xylem is narrow. The pith is big, the cells are more tangible, and there are no inland sea objects. On the surface, epidermal cells are polygonal or rectangular. [Physical and chemical identification]: Preparation of TLC sample: Take 1g stem and leaf powder (60 mesh), soak it in 20ml ether for 4 hours, and concentrate it before sampling. Adsorbent: silica gel G (Qingdao) paving, 105℃ activation 1 hour. Developing agent: hexane-acetone (6: 4). Span 1 1cm. Colorant: iodine vapor develops color with yellow spots.
