A development of a Digital tongue diagnosis system using the tongue color analysis of the each taste region

Computer-assisted image analyses were performed on the tongue color of 95 medical students without previous history of blood stasis-related condition to clarify the mutual relationship of the color of the tongue proper, the coating, and sublingual vein. The location of the measurement for the tongue proper was the underside of the tongue, and location of the measurement for the tongue coating was the upper surface of the tongue. A linear correlation analysis showed a correlation for each of the different positions for the non-normalized red value and normalized blue value. This analysis also demonstrated a statistically-significant relationship between the tongue proper and the sublingual vein using Red-Green-Blue components and normalized Red-Green-Blue components (r=+0.670-0.817, p < 0.0001). The most significant correlation between the tongue proper and the sublingual vein was the normalized red value and the normalized Red-Green-Blue values for minimizing the range of the standard error of the mean (r=+0.745, p < 0.0001), although non-normalized blue had the highest correlation coefficient. Therefore, it seems reasonable to select those normalized red values for the comparison in the tongue color analysis. Correlation of the color between the sublingual vein and the tongue proper strongly suggests that inspection with the naked eye of the sublingual vein is useful for the early detection of vital energy stagnation and blood stasis. Also, because of its close relation to sustained chronic stress, changes in the sublingual vein might be available as one physiological parameter of a stress reaction.

Tongue Diagnosis

Tongue diagnosis is an important procedure in traditional Korean medicine (TKM). In particular, tongue coating thickness (TCT) is deemed to show the progression of the disease. However, conventional tongue diagnosis has limitations because of various external factors. Therefore, it is necessary to investigate the availability of tongue diagnosis system (TDS) in the assessment of TCT. This study has been designed as a prospective clinical trial involving 60 patients with functional dyspepsia. Tongue images will be obtained by TDS twice with a 30 min interval. The system will measure the percentage of TCT and classify it as either no coating, thin coating, or thick coating according to the existing diagnostic criteria. After finishing the collection of 60 patients' tongue images, TCT on the images will be simultaneously evaluated by the conventional method to establish the gold standard for assessing TCT by 5 well-trained clinicians. The evaluation will be repeated by the same clinicians after 2 weeks, but the order of the images will be changed. This trial is expected to provide clinical evidence for the availability of TDS as a diagnostic tool and to contribute to the standardization of the diagnosis system used in TKM. This trial is registered with ClinicalTrials.govNCT01864837.

Tongue Color

Introduction. Breast cancer (BC) is the most common cancer in women and patients with BC often undergo complex treatment. In Taiwan, nearly 80% of patients with BC seek traditional Chinese medicine (TCM) during adjuvant chemotherapy to relieve discomfort and side effects. This study investigated tongue features and pattern differentiation through noninvasive TCM tongue diagnosis in patients with BC. Materials and Methods. This cross-sectional, case-controlled, retrospective observational study collected patient data through a chart review. The tongue features were extracted using the automatic tongue diagnosis system (ATDS). Nine tongue features, including tongue shape, tongue color, fur thickness, fur color, saliva, tongue fissures, ecchymoses, teeth marks, and red dots, were analyzed. Results and Discussion. Objective image analysis techniques were used to identify significant differences in the many tongue features between BC patients and non-BC individuals. A significantly larger proportion of patients with BC had a small tongue ( p < 0.001 ), pale tongue ( p < 0.001 ), thick fur ( p < 0.001 ), yellow fur ( p < 0.001 ), wet saliva ( p < 0.001 ), thick tongue fur ( p < 0.001 ), fissures ( p = 0.040 ), and ecchymoses in the heart-lung area ( p = 0.013 ). According to logistic regression, small tongue shape, pale tongue color, yellow fur color, wet saliva, and the amounts of fissures were associated with a significantly increased odds ratio for BC. Conclusions. This study showed significant differences in tongue features, such as small tongue shape, pale tongue color, thick fur, yellow fur color, wet saliva, fissure, and ecchymoses in the heart-lung area in patients with BC. These tongue features would imply yin deficiency, deficiencies of blood, stagnation of heat, and phlegm/blood stasis in TCM theory. There is a need to investigate effective and safe treatment to enhance the role of TCM in integrated medical care for patients with BC.
