Introduction: More than 30 years have passed since the revived and developed of traditional medicine, and dozens of textbooks and publications on traditional medicine have been published and qualified personnel have been trained. However, there is a need to drastically improve the quality of traditional medical care and the knowledge and skills of doctors. Therefore, it is important to translate, study books written by ancient physicians, maaramba, and scholars, and to apply theory, diagnosis, and treatment methods in training and practice. Research materials and methods: Basic research materials: Naiman toin Jambaldorj (1792-1855). གསོ་བྱེད་མཛས་མཚར་ མིག་རྒྱན། Tibetan scripture of a wooden printing block. Method: We used germenevtic method and checklist method. Result: In the frame of this research, we used the medical sutra written by Jambaldorj as the main material in order to clarify the specialty and number of animal-oriented medicines in the “mdzes mtshar mig rgyan”. During the research, it was possible to clarify the structure, general content, and specialty of the sutra written by Jambaldorj, classify animal-oriented medicines according to the cyrillic alphabet, and make allegory names for some of the raw materials of animal origin. In addition, the study of animal-oriented medicines in the sutra showed that many issues were important, such as their identification, usages, and new production. As a result of the first study, we identified the characteristics and usages of some essential animal-oriented medicines. Conclusion Jambaldorj began writing the “mdzes mtshar mig rgyan” before leaving for Tibet, and later, during his pilgrimage to Tibet, he enriched and completed it in his book. It was found to correspond to the period 1817-1823. A selection of 124 animal-oriented medicines from the book “mdzes mtshar mig rgyan” was made. In this way, it is possible to interpret and explain the hidden meanings of animal-oriented medicines in this sutra, and to determine the usages of pharmacology and drug formulations.

Introduction: The basis of the development of traditional Mongolian medicine in the 21st century is the importance of reading and studying the biographies of previous generations of ancient doctors and scientists, as well as old medical books and sutras. For example, it is important to gain a deeper understanding of the scientific basis of the ancient medical books, and to understand the manuals and treatment’s methods of doctors and maarambas. Research goal: Studying the biography of Erdene Bandida Khutagt, Khamba Nomuun Khan Hanchen Choijal Luvsandanzanjantsan, and his medical book titled “gsal ba’i sgron me”. Research methods: We used following study methods; manuscripts, primary source methods, hermeneutic method, matrifocal listing method, historical comparative method and analysis synthesis method. Result: Erdene Bandida Khutagt, Khamba Nomuun Khan Hanchen Choijal Luvsandanzanjantsan, the first incarnation of the Lama Gegeen, was born on the 15th of January 1639, in Ulziit Ovoo, Sain Noyon Khan aimag. In 1643, at the age of five, he was initiated by Namkhaisodnomdagva and named Choijidorj. In 1644, at the age of six, he went to Tibet in order to study Tibetan script, calligraphy, and secret tantric rituals and other subjects including medicine taught by Luvsanyarpel, who came to Mongolia from the Dashlkhumbe Monastery of Tibet. Thus, from an early age, he was immersed in religious and medical teachings. Luvsandanzanjantsan has written five books in Tibetan. We selected the book titled “mkhan chen chos kyi rgyal poi gsung ‘bum las gso ba rig pa’i rtsa rgyud kyi’ grel pa gsal ba’i sgron me ces bya ba bzhugs so” as our main subject of study. The book clearly explains the “Root Tantra” of the “Four Medical Tantras”, clarifies the difficult words and content of the theory and makes it easier for people to learn. In addition, we have studied the structure, content, and concluding remarks of this book. Conclusion Luvsandanzanjantsan was not only a scientist who penetrated the five great sciences, but also made a valuable contribution to the expansion of Mongolian medical research field and the introduction of Tibetan medicine into Mongolia. He is credited with reviewing and commenting on the best medical works of Indian and Tibetan scholars.
