Tibetan medicine has always attached great importance to the selection of raw materials for Tibetan medicine. Among the processing of Tibetan medicine materials, the processing of mineral medicine materials is the most magical. Cold water stone can be processed in different ways, so that its medicinal properties change in different or even opposite ways, thus producing various therapeutic effects. In Tibetan medicine, gold, silver, copper, iron, tin, etc. can all be used as medicine, but not directly, but through special processing technology, it undergoes qualitative changes and becomes a medicinal active ingredient with specific therapeutic value. For example, the processing of iron filings is to place it in a liquid prepared with plants and soak it for 35 days. The iron filings will turn into a yellow mud-like substance, which can be used as medicine. As the saying goes: Real gold is not afraid of fire. After the Tibetan medicine process technology is used for processing, gold turns into black gold charcoal, becoming an indispensable medicinal active ingredient for treasure-like Tibetan medicine. The processing technology of mineral medicinal materials is extremely complicated. Some of the medicines are derived from famous ancient Tibetan medicine prescriptions and ancient proven prescriptions, which were created by famous doctors in history. After hundreds or even thousands of years of clinical application, they are generally recognized to have significant or special effects. The processing and refining process of various precious Tibetan medicines is very rigorous and is a highly difficult technology. In particular, the alchemy technology for making the king of nectar essence, -, has a history of more than 2,000 years. Only a few famous doctors with the most historical influence can make -. Before the peaceful liberation of Tibet, only a very small number of famous doctors in Lhasa Tibetan Hospital and Yaowang Mountain could make -, and the rest of the Tibetan area had lost it. After the peaceful liberation of Tibet, because the Party and the government attached great importance to the medical and health cause of ethnic minorities, they provided long-term support in terms of manpower, material resources, financial resources and policies, which greatly developed the medical facilities and production and processing conditions of Tibetan medicine. The enthusiasm of Tibetan medicine workers in the whole Tibetan area increased, and this unique skill that was facing extinction was soon saved. While Tibetan medical institutions were gradually established in the whole Tibetan area, various pharmaceutical process technologies were inherited through various means such as training, further studies, master-apprentice relationship, and invitation exchanges. Tibetan medicinal material processing and preparation is to process and prepare drugs in various ways according to the needs of clinical treatment and preparation. The purpose of processing is to remove impurities and non-drug parts, eliminate or reduce the toxicity of drugs, change or alleviate the medicinal properties and efficacy of drugs, improve clinical treatment effects, and facilitate preparation and storage.
