Pathophysiology of cerebral ischemia-reperfusion injury: An overview of oxidative stress and plant-based therapeutic approaches

[Display omitted] •Oxidative stress plays a crucial role in cerebral ischemia–reperfusion injury.•Plant-based therapies offer potential neuroprotection in ischemic conditions.•Focus on low-toxicity, cost-effective options for treating ischemic stroke.•Plant extracts counteract pathophysiological processes in ischemia–reperfusion injury.•Highlights the need for natural, efficient treatments for stroke-related damage. Stroke is a debilitating neurological disorder that causes substantial morbidity and mortality on a global scale. Ischemic stroke, the most common type, occurs when the brain’s blood supply is interrupted. Oxidative stress is a key factor in stroke pathology, contributing to inflammation and neuronal cell death. As a result, there is increasing interest in the potential of plant extracts, which have been used in traditional medicine for centuries and are generally considered safe, to serve as alternative or complementary treatments for stroke. The plant extracts can target multiple pathological processes, including oxidative stress, offering neuroprotective effects. The development of highly efficient, low-toxicity, and cost-effective natural products is crucial for enhancing stroke treatment options. In this review, we examine 60 plant extracts that have been focused on the studies published from year 2000 to 2024 along with the studies’ experimental models, dosages, and results. The plant extracts hold promise in modulating cerebral ischemia–reperfusion injury through counteraction of relevant pathophysiologic processes such as oxidative stress.
