Effect of CHS extracts on on COX-2 expression: (a) Western blot; and (b) quantitative analysis of COX-2 bands. Data are expressed in comparison to control (100%) after the signal was normalized against β-actin. rosemary ethanol (RE); sage ethanol (SE); bay leaf ethanol (BLE), ginger ethanol (GE), and turmeric ethanol (TE) and their combinations (rosemary and turmeric ethanol (RTE), bay leaf and sage ethanol (BLSE), sage and ginger ethanol (SGE) on COX-2 expression in HCA-7 cells. * Statistically significant different from control (p < 0.05), n = 3, ±SEM. Untreated control contained just DMEM with 10% FBS (vehicle control–ethanol was 0.4% (v/v), the highest amount found in the extracts).
