The loose powder or precipitated fine crystals that have been processed and processed by the drug are called “frosting†due to their similarity to the cold cream. This processing method is called “frosting†in Chinese medicine processing. Drugs are used to reduce the toxicity of drugs, ease drug properties, eliminate toxic and side effects, and enhance efficacy. In actual work, each with different frosting principles, the frosting method can be divided into degreasing, creaming, frosting, weathering and defrosting. The introduction is as follows: Degreasing to frost This method is mainly used for seed oils pressed with oil and its powder. Its purpose is to remove the toxic substances contained in the oil, such as croton cream, or to be easily taken and crushed, such as Boziren cream. The specific method of manufacture varies by region and has a slightly different approach. In a large number of operations, the seeds are first sun dried, crushed and seed coats are crushed, and the kernels are crushed and steamed. The oil is then squeezed with a squeezer, and then taken into a cake, dried and ground, and sieved to remove fines. At the end, that is. A small amount of medicine is shattered and wrapped in straw paper. After drying or baking, the oil is sucked by the paper and the paper is changed frequently. When the oil is sucked up, no traces of oil are found on the paper. The medicine is loosely powdered and no longer adheres. degree. Sublimation into frost This law mainly refers to certain mineral medicines obtained through sublimation and refining to obtain very fine pure powder, such as arsenic, etc., and the plant medicines are sublimated through carbonization to obtain fine particles such as paraquat cream. Weathered into frost The term “weathered†has two meanings: First, it refers to certain inorganic compounds containing water of crystallization, which volatilize naturally in the air to crystallize water, and then become powder, such as weathered nitrite. The other is that some melon and fruit medicines are processed into white frost on the surface of the air after certain processing. For example, the watermelon is peeled, the child is cut and the Glauber's salt is cut, and the mixture is filled and filled. Sealed with yellow mud, ventilated place, about two weeks into a frost, about 5kg Mirabilite to 1kg cream. There are also cut the beginning of the watermelon, remove the child, filled with Glauber's salt, wrapped in rope, hanging in a cool, ventilated place, the cream gradually precipitated, bamboo knife scraping research and then that is. The same method can also be made cucumber cream. By-product frosting This method mainly refers to the bone powder that remains in the animal's horns after the gel is removed, such as frost cream.
