Medical application of fuzzy theory to the diagnostic system of tongue inspection in traditional Chinese medicine

Abstract

Traditional Chinese medicine has a systematized methodology of medical treatment, based subjective information from the five senses. We proposed a diagnostic system for tongue inspection using fuzzy theory and applied this system to healthy volunteers based on traditional Chinese medicine. This system diagnosed syndromes such as deficiency syndrome, excess syndrome, coldness syndrome, and heat syndrome. We mainly focused on the evaluation of the coldness syndrome and the heat syndrome. The results suggested that this diagnostic system is useful for tongue inspection of traditional Chinese medicine.
