Moreover, it contributes towards maintaining a peripheral bloodstream (Boelsma et al. 2004; Mehlsen et al. 2002; Pittler and Ernst 2000). During a clinical study of over 60 subjects that was based over a period of between 12 to 18 months depending on the subject, results have shown the capacity of ginkgo biloba to improve the problem of erectile dysfunction that is attributable to a deficient blood flow in erectile tissues. (Sikora R, Sohn M, et al. Ginkgo biloba extract in the therapy of erectile dysfunction. J Urol. 1989: 188A).
