Gingko Biloba shown to protect optic nerve cells from injury
Oral consumption of Ginkgo biloba led to a higher survival rate of optic nerve cells (retinal ganglion cells). The effect was dosage-dependent - the higher concentrations of Ginkgo resulted in higher optic nerve cell survival rates. The dosages of Ginkgo were comparable to those an average person could safely consume.
