Lhasa Northern Tibetan Medicine is one of the main schools of Tibetan medicine. The "1 Refining Method" and "Renqing Changjue Compatibility Technique" are unique drug processing techniques. The Tibetan medicine "1 Refining Method" is referred to as "1 Processing" or "Zuozhu Qinmo". The Tibetan people call "Zuozhu Qinmo" the treasure of Tibetan medicine. It is the king of medicine "Zota" that is non-toxic and has a unique curative effect after the highly toxic 1 is processed by famous Tibetan doctors of all generations through complex special processing. As an important processing method of Tibetan medicinal materials and the only essence of Tibetan medicine practice, Tibetan medical scholars of all generations have attached great importance to the practice and inheritance of this technology for thousands of years, and have passed it down from generation to generation, so that this technology has been carried forward to this day. The practice method of 1 processing was first recorded in the "Four Medical Classics" compiled by Yutuo Ningma Yundan Gongbu in the 8th century AD, and was explained in detail in the formula of the precious medicine "Renqing Changjue" pills. At the end of the 13th century, the great saint Ugyenpa Rinchenbei successfully carried out the entire practical operation of "1 washing and refining" such as hot and cold treatment and detoxification, and compiled works such as "1 Treatise on the Preparation of 1", creating a complete practical operation of the Tibetan medicine "1 processing" system, and made an immeasurable contribution to the popularization and promotion of "1 processing". Later, through the continuous practice and inheritance of famous Tibetan medicine scientists such as the sage Karmapa Rangjung Dorje, Sukhanenni Dorje, and Gongzhu Yundan Gyatso, the essence of this Tibetan medicine culture has been passed down from generation to generation and continues to protect human health. "Zota" after 1 washing and refining is an indispensable and important raw material for the preparation of precious Tibetan finished medicines. It has a long history of use in Tibetan medicine. After nearly two thousand years of clinical practice verification, it has a wide range of applications and a large amount of use. It is the best among Tibetan medicines, and has the effects of prolonging life, strengthening the body, reducing toxicity and increasing efficacy.

Tibetan Medicine Ganzi Prefecture Southern Tibetan Medicine Application Area or Unit: Ganzi Tibetan Autonomous Prefecture, Sichuan Province Tibetan medicine has a history of nearly 2,300 years. It is a medical system with a complete theoretical system, unique treatment methods and strong ethnic characteristics formed by the Tibetan people through long-term practice and continuous accumulation and improvement. In history, Tibetan medicine has formed two schools, northern and southern. Ganzi Prefecture is one of the birthplaces of Tibetan medicine and the hometown of southern Tibetan medicine. Historically, Tibetan medicine centered on Kham is called southern Tibetan medicine. The Kham area includes Ganzi Prefecture in Sichuan, Diqing Prefecture in Yunnan, Changdu area in Tibet and Yushu Prefecture in Qinghai, with a total area of 550,000 square kilometers. Tibetan medicine was studied from the 12th to the 15th century AD, and the northern Tibetan medicine represented by Xiangbalangjia Zasang and the southern Tibetan medicine represented by Sukananiangni Dorje were produced. Southern Tibetan medicine was inherited and developed by Tibetan medicine scientists such as Jieba Zeweng, Shakya Wangqiu, the Fifth 01, Dammen Ranba Losang Qupi, etc. It was not until Sidu Queji Jionglie that the southern and northern Tibetan medicine gradually merged into one, and the southern Tibetan medicine once became the backbone of Tibetan medicine, leading the inheritance and development of the entire Tibetan medicine. In the early 19th century, the southern Tibetan medicine scientists represented by Jiayang Qingze Jiangbu and others made Tibetan medicine unprecedentedly developed. Tibetan medicine is an important part of Tibetan culture and has extremely important value in studying the development of Tibetan society. At the same time, it plays an important role in protecting people's health. With the harm caused by environmental deterioration to human health, the toxic side effects of chemical drugs and the helplessness faced in the treatment of diseases, human beings are increasingly aware of the important role of Tibetan medicine in health care. Modern science has further confirmed the scientific value of Tibetan medicine in human health care and disease prevention.
