Proliferation inhibition rates of different human colorectal carcinoma cells treated with a superior triphala (higher chebulinic acid, higher chebulagic acid); b inferior triphala (lower chebulinic acid, lower chebulagic acid); c inferior triphala with corrected chebulinic acid (higher chebulinic acid, lower chebulagic acid); and d inferior triphala with corrected chebulagic acid (lower chebulinic acid, higher chebulagic acid) or e chebulinic acid or f chebulagic acid at concentrations of 25, 50, 75, 100, 125, and 150 mg/L for 48 h. The relative IC₅₀ values were estimated with regression analysis by probit using SPSS and presented in Table 1
