Protective Potentials of Natural Products Against Vascular Dementia: A Comprehensive Review of Experimental Studies

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Vascular dementia (VaD), accounting for up to 20% of dementia cases globally, is primarily driven by chronic cerebral hypoperfusion (CCH), which leads to progressive cognitive impairment. Despite the increasing prevalence of VaD, effective treatments remain limited.

Potential of Ginkgo biloba Extract to Intervene in Chronic Inflammation‐Related Diseases

open access: yesPhytotherapy Research, EarlyView.
Chronic inflammation is a pathological mechanism underpinning many diseases. Ginkgo biloba extract (GBE) is well known for its anti‐inflammatory property. GBE and its active constituents have been shown to attenuate pro‐inflammatory cytokine production, suppress nuclear factor kappa B activation, restore redox homeostasis, and modulate disease‐relevant
