Ginkgo biloba. Animal studies demonstrate that ginkgo improves glucose metabolism in muscle fibers and prevents atrophy (Punkt 1999). Animal studies also show that ginkgo biloba extracts significantly inhibit post-meal sugar levels and act as anti-hyperglycemic agents (Tanaka 2004).
Ginkgo biloba extract has been shown to prevent diabetic retinopathy in diabetic rats, suggesting a protective effect in human diabetics (Doly 1988). In a preliminary clinical trial (Huang 2004), type 2 diabetics were given ginkgo extract orally for three months, which significantly reduced free radical levels, decreased fibrinogen levels, and improved blood viscosity. Ginkgo extracts also improved retinal capillary blood flow rate in type 2 diabetic patients with retinopathy.
Ginkgo has also been observed to lower blood glucose levels. It was studied in type 2 diabetics at a dose of 120 mg for three months. Ginkgo supplementation produced an increase in liver metabolism of insulin and oral hypoglycemic medications, which corresponded to a reduction in plasma glucose levels (Kudolo 2001). Type 2 diabetics with pancreatic exhaustion received the most benefit. Ginkgo does not appear to increase beta cell production; rather it enhances liver uptake of existing insulin, thereby reducing high insulin levels.
