Evaluation of Oxygen Radical Absorbance Capacity in Kampo Medicine

Figure 1

Difference of the ORAC value of Kampo formulas according to the additional herbs added to the basic Kampo formula. Major change patterns were classified into six groups in this study. Group A, which had little change of ORAC value, consisted of shokenchuto and tokikenchuto shown in Table 2, and keishikajutsubuto and keishikaryojutsubuto shown in Table 4, respectively. Group B, which had mild increase of ORAC value compared to base Kampo formula, consisted of ogikenchuto shown in Table 2, and tokishigyakukagoshuyushokyoto shown in Table 4, respectively. Group C, which had mild decrease of ORAC value compared to base Kampo formula, consisted of hachimijiogan and goshajinkigan shown in Table 3, and keishikaryukotsuboreito and keishikakobokukyoninto shown in Table 4, respectively. Group D, which had high increase of ORAC value compared to base Kampo formula, consisted of keishikashakuyakudaioto shown in Table 2. Group E, which had high decrease of ORAC value compared to base Kampo formula, consisted of keishikaogito and keishikakakkonto shown in Table 4. Group F, which had much high increase of ORAC value compared to Group E, consisted of kakkonto and kakkontokasenkyushin'i; shown in Table 4.
