Lead is a heavy metal abundant in nature that causes haematological imbalances, and hepatic and renal dysfunction, and this imbalance has been linked to oxidative stress. Several reports have shown that natural products are implicated in ameliorating metal poisonings. Ginkgo biloba is a flavonoid-rich natural herbal supplement with several pharmacological properties. The present study investigated effect of Ginkgo biloba supplement (GBS) on lead-induced toxicity. Animals were given a lead dose of 25 mg/kg for 14 days orally and then given Ginkgo biloba supplements of 50 mg/kg and 100 mg/kg orally for 14 days. Animals given GBS had significantly improved haematological and rheological parameters. GBS showed a protective impact in terms of improved kidney and liver histology, anti-oxidant enzyme activity (CAT, SOD, GSH, and MDA), organ function indices, and a lower rate of erythrocyte osmotic fragility. Conclusively, Ginkgo biloba supplementation attenuated lead toxicity by normalization of haematological imbalances, and hepatic and renal dysfunction as well as maintaining erythrocyte membrane integrity.

Background: Reliable treatment approaches for addressing early cognitive impairment and Alzheimer's disease (AD) are currently lacking. Given the multifactorial nature of AD, therapeutic strategies need to focus on disease-specific biochemical pathways. Given the significance of metabolic pathways in cognitive impairment, it is essential to investigate alternative disease modifiers capable of targeting multiple metabolic pathways, such as phytochemicals.

Background: Ginkgo biloba leaf extract EGb 761® has shown clinical efficacy in patients with mild cognitive impairment and dementia. However, the pharmacological action of EGb 761® in Alzheimer's disease (AD) remains unclear and molecular mechanisms targeted in the brain are not completely understood.
Hypothesis/purpose: We aimed to investigate 1) the potential sex-dependent effects of oral administration of EGb 761® in 5xFAD mice, an AD mouse model, and 2) the underlying microglial subtype responsible for the observed anti-inflammatory effects in the brain.

Vascular dementia (VD) is a neurocognitive disorder resulting from cerebral vascular disorders, leading to the demise of neurons and cognitive deficits, posing significant health concerns globally. Derived from Ginkgo biloba leaves, EGb761 is a potent bioactive compound widely recognized for its benefits in treating cerebrovascular diseases. Previous studies have demonstrated that the administration of EGb761 to VD rats enhances the proliferation, differentiation, and migration of neurons, effectively alleviating cognitive dysfunction.

Although GBE has been extensively studied in the prevention and treatment of lung diseases, its mechanism of action in chronic obstructive pulmonary disease (COPD) is unclear. In the present study, cigarette smoke extract (CSE) and cigarette smoke (CS) were used to induce COPD in cell and animal models.
