Artemisia absinthium (wormwood; WO) is a plant known for its anticancer potential and this study comprehensively evaluates the effects of WO, alone and in combination with Temozolomide (TMZ), on cytotoxicity, apoptosis, autophagy, mitochondrial membrane potential, cell migration, and nitric oxide synthase (NOS) responses in T98-G glioblastoma cells. Cytotoxicity, apoptosis, autophagy, mitochondrial membrane potential, and cell migration were assessed using MTT, Annexin V-FITC/PI, JC-1, monodansylcadaverine (MDC) staining, and wound healing assay, respectively. Protein levels of eNOS, iNOS, and LC3-II were examined using immunofluorescence and western blotting. WO significantly reduced T98-G cell viability in a dose- and time-dependent manner with pronounced cytotoxicity observed at 48 and 72 hours. The combined treatment increased early (24.6%) and late (40.5%) apoptosis, reducing cell viability to 31.9%. Combined treatment markedly increased autophagic vacuoles, enhancing perinuclear and cytoplasmic accumulation compared with single agents. Combined WO and TMZ treatment disrupted mitochondrial membrane potential more prominently than either agent alone, suggesting that apoptosis is mediated via the mitochondrial pathway. WO strongly inhibited T98-G cell migration, whereas TMZ and the combination had moderate suppressive effects. In T98-G cells, WO IC₅₀ significantly increased eNOS (p
