A Historical Review of Persian Medicine Studies into Saliva Manifestations for Potential Applications for Diagnosis and Management of Metabolic Syndrome

Background and Objectives: Regarding the development of diagnostic tests based on saliva and the prevalence of metabolic syndrome (MetS), the aim of this study is to review Persian Medicine manuscripts in the field of saliva manifestations, its relation to metabolic syndrome, and treatment recommendations. Methods: This study is a mini-review. We investigated the canon of medicine and some important Persian medical or pharmaceutical manuscripts from the 9th to the 19th centuries. PubMed and Google Scholar databases were explored for finding relevant information about the relationship between saliva and metabolic syndrome and its treatment. Results: Studies have suggested that maldigestion is one of the important causes of MetS. Sialorrhea may be an early symptom of maldigestion. Attention to sialorrhea and its treatment may be useful in the prevention and treatment of metabolic syndrome based on PM sources. In PM, sialorrhea is treated with 3 major approaches: lifestyle modification along with simple or compound medicines. Conclusion: Saliva manifestations could be considered as early symptoms of metabolic syndrome. As mentioned in WHO strategies, traditional medicine can be used along with modern medicine due to its effectiveness in the management of various ailments.
