Objectives:This study aimed to assess a Qi Blood Yin Yang evaluation method systematically and objectively and to identify the correlation between the Qi Blood Yin Yang deficiency pattern (QBYYDP) and facial color.
Methods:Thirty-seven participants (17 males, 20 females) were enrolled in this study. Twenty-four (10 males, 14 females) had ages from 40 to over 60, and 13 (7 males and 6 females) were in their twenties. After sufficient rest, facial images were taken with a camera. Based on the results from a questionnaire survey, we divided the participants into five groups: the normal and the Qi-, Blood-, Yin-, and Yang-deficient groups, after which the relationships between the L, ¡®a¡¯, and ¡®b¡¯ values in the Lab color system and the characteristics of the participants in each of the deficient groups were elucidated using a facial color analysis program.
Results:The color analysis for Qi-deficient (QD) participants revealed that the L value was fairly decreased in comparison with the normal participants, but the ¡®a¡¯ and ¡®b¡¯ values were almost the same. A comparison between the normal and the Yang-deficient (YaD) groups revealed that the L values were somewhat lower compared to the normal group, but the ¡®a¡¯ and ¡®b¡¯ values were not statistically different. For the Yin-deficient (YiD) group, the L value was slightly lower compared to the normal group, but the ¡®a¡¯ and ¡®b¡¯ values were almost the same and the R values were slightly increased. For the Blood-deficient (BD) group, the L values were slightly increased compared to the normal group, but the ¡®a¡¯ and ¡®b¡¯ values were decreased slightly.
Conclusion:This study obtained objective, reliable data for judging the QBYYDP by using facial images and a color analysis program. However, further study with at least 10 or more subjects in each of the deficient groups is necessary to confirm our findings.
