Neurological deficit was assessed (Bederson scale), while histopathology, oxidative stress markers (MDA, GSH, SOD, CAT, NOx), and cytokines (IL-6, TNF-α, IL-1β) were measured. Groups included Normal (no ischemia), Ischemia (oral placebo), Citicoline 300 mg/kg, ChS 500 mg/kg, BaG 500 mg/kg, and the oral combination ChS 500 + BaG 500 mg/kg, all administered for seven days prior to ischemia induction. &lt;strong&gt;Results: &lt;/strong&gt;ChS had higher total phenolic content than BaG (p = 0.0079). GC-MS identified 23 compounds in ChS and 17 in BaG. The combination displayed greater antioxidant activity than either extract. At 24 h, ChS 500 mg/Kg and the combination reduced severe neurological deficit to 17% (vs. 83% in ischemia). Histopathology revealed less neuronal damage with the combination, comparable to ChS 500 mg/Kg. All treatments decreased MDA levels; the combination also enhanced GSH and CAT and significantly reduced TNF-α and IL-1β. &lt;strong&gt;Conclusion:&lt;/strong&gt; ChS and BaG extracts exert neuroprotective effects against cerebral ischemia. Their combination shows synergistic antioxidant activity against free radicals and enhances the modulation of inflammatory cytokines, supporting a greater neuroprotective potential.&lt;/p&gt;
