Introduction: Based on the results of recent scientific research mongolian traditional medicine (MTM) is one of the ancient medical practices with a history spanning 5,000 years. Since immemorial. Doctors of traditional Mongolian medicine, physicians have incorporated the research of local climate, seasonal changes, diet, and ifestyle into their treatment practices. This study considers it necessary to conduct a comparative analysis of the "AMIDRUULAGCH EMIIN SUDAR" and the "EM ZASLYN SARAN KHAAN" in order to understand the patterns of seasonal diseases and the physiological characteristics of the human body presented in the two ancient wood print above. The rationale of this study lies in clarifying the historical development of Mongolian traditional medicine, as well as certain diagnostic methods and therapeutic techniques, by identifying the similarities and differences between these two primary sources. Methods: A retrospective clinical study was conducted at the Traditional Medicine Department of the "Sindura- Med" Hospital between September 15. 2025, and March 30, 2026. The study included a total of 3,487 patients aged 1-60 years. Using comparative source analysis and statistical methods (SPSS 16.0), the clinical data were analyzed against the theoretical frameworks of the Em zaslyn saran khaan and the Amidruulagch emiin sudar. seasonal timing was standardized using the Gregorian calendar equivalents established by Dr. L. Terbish (1999).
A total of 3,487 people were included in the study. The comparison between the "Em zaslyn saran khaan" and the "Amidruulagch emiin sudar" shows that seasonal dynamics and disease progression differ between the two texts. Specifically, the statistical indicators of disease occurrence during the "Wind" (Khii) called movement months of the four seasons (December. January, and February) in the "Em zaslyn saran khaan" align more closely with the participants' data than the six-season "Wind" movement months (June, July, and August) described in the "Amidruulagch emiin sudar." Conclusion The seasonal disease dynamics and humoral fluctuations described in the Em zaslyn saran khaan are more consistent with the current climatic conditions and disease patterns observed in Mongolia than those outlined in the Amidruulagch emiin sudar. The study confirms that the four-season framework of the Somarazha remains a highly relevant diagnostic and preventive tool for contemporary Mongolian traditional medicine.
