Effects of Chromolaena odorata extract on MRC-5 cell viability. Cells were exposed to 15.625–1000 µg/mL of Chromolaena odorata extract for 24 h. The percentage of cell viability was determined by MTT cell viability assay. The results were represented as a percentage of control. Data were expressed as the mean ± SEM (n = 3). *** p < 0.001, significantly different from the control, ** p < 0.01, significantly different from the control, * p < 0.05, significantly different from the control.
