I. viscosa leaves and stems methanolic extracts reduced viability of A549 lung cancer cells. A549 cells were treated with I. viscosa leaves or stems extracts at the indicated concentrations for 24 h. Cell viability was determined using the MTT assay, and results were expressed as viability percentages compared to control vehicle-treated cells. Data represent the mean ± SEM (n = 3). * denotes p < 0.05, ** p < 0.01, *** p < 0.001, and **** p < 0.0001.
