Introduction

Introduction Gingko biloba has existed for over million years and is indigenous to Korea, Japan, and China, but can be found worldwide. Open in a separate window. Efficacy, safety, and use of ginkgo biloba in clinical and preclinical applications.

Therefore, the conclusions are based on extrapolation of other studies. The single components of Ginkgo extract showed a protective effect in both cell models of the mitochondrial membrane potential as well. Optic disc hemorrhages are associated with a higher risk for progression. Optic disc hemorrhages often occur in glaucoma patients and are associated with reduced prognosis. Besides, in a placebo-controlled, double-blind study, treatment with Ginkgo biloba has induced some reversibility of visual field damage in patient with normal tension glaucoma.

Most pharmacological, toxicological and clinical studies have focused on the neuroprotective value of these two main extracts. There are several published case reports linking Ginkgo to episodes of minor to severe bleeding.
