Background: The medical works written by Darmo Maaramba Luvsanchoidog have been an important source for the theory, treatment, training and research of traditional Mongolian medicine. In recent years, number of his medical books written by dbu med (in English headless scriptures) have been found, but they are difficult to read or translate and have not been studied at all in Mongolia. Therefore, the study has been carried out to facilitate the use of handwriting medical scriptures by Darmo Maaramba Luvsanchoidog for research, teaching, and to explain complex words in his books. Purpose: Explain the difficult words related to precious medicines in the book called “legs bshad be ed’u dkar poi ‘phreng ba zhes bya ba bzhugs so” written by Darmo Maaramba Luvsanchoidog. Research methods: Methods of textual analysis for ancient books and analysis and synthesis were used in the study. Conclusion In the book “legs bshad be ed’u dkar poi ‘phreng ba zhes bya ba bzhugs so” written by Darmo Maaramba Luvsanchoidog clearly outlines the method of analyzing the sources of many precious medicines. Furthermore, the research identified that “legs bshad be ed’u dkar poi ‘phreng ba zhes bya ba bzhugs so” is a significant work to understand precious medicines in the main scriptures of medicine and thoroughly explained their content and terminology. In particular, ring srel (in English relic), which has long been forgotten in traditional medicine, has gained practical significance as it clearly explains its classification, nature, and use.

Most recent researches by our historians and archeologists showed that Traditional Mongolian Medicine has undergone 5000 years of historical development which contained all the features of nomadic medicine. Among this 5000 years, the Tibetan medicine particularly, some of the Tibetan doctors their books and sutras influenced a lot into our medical system. Darmo Menrampa Lobzang Chodrak was one of the Tibetan doctors who played important role in field of Mongolian Medicine.
In the course of the research, we have summarized data of over 10 sources and determined that the following books and sutras have been written in medicine without overlapping. From the many of the medical works of Dharmo maaramba wrote, medical sutra that was written in text during his time among Mongols, was found Inner Mongolian Autonomous Region of China, which indicates that he has had a profound impact on Mongolian medicine and the literature spread through Inner Mongolian Autonomous Region of China and Mongolia and is still being used in training, research and practice. In the ancient Tibetan books, the Dharmo maaramba was pronounced in Mongolian as «Darkhan Tengeryn Ezen,” «Otoch Khan» and «Dharmo Emch.”
His name was included in the list of teachers of Zaya Bandida Luvsanprinlei (1642-1708), which is undoubtedly the fact that Dharmo maaramba was his teacher.
