Objectives: Cupping therapy has been used as various treatment methods in oriental medicine clinic for a long time. Specially, Cupping stimulation caused skin hyperpigmentation which has been used as diagnosis method for extravasated blood & inner organs functional disease. But it was difficult to quantitatively measure and analyze the interrelation between extravasated blood and skin hyperpigmentation. The aim of this study is to measure the acupoint’s RGB and melanin change pattern by stimulating under fixed 80kPa negative pressure and to evaluate the extravasated blood.
Methods: To evaluate extravasated blood, 10 acupoints (left/right BL13, BL15, BL18, BL20, BL23) were stimulated by treatment 80kPa negative pressure for 1 minute. And then we measured the acupoints’ skin color change patterns using the color meter, followed by RGB analysis and melanin change pattern.
Results and Conclusions: We could observe the correlation of the acupoints’ skin color condition related with RGB change pattern. All acupoints’ color change degree were different. Regardless of acupoints’ color degree due to extravasated blood, we observed in common the fact that RGB values decreased after stimulation and steadily increased according to time. We observed that melanin index increased after stimulation and recovered before stimulation-condition after the lapse of time. In other words, we confirmed the correlation between raised color change degree and L²a² index change pattern. Therefore we observed the possibility of charting the L²a² index following extravasated blood.
