120 mg up to 360 mg of Ginkgo a day should be taken in divided doses. A 1998 Italian study found 65 percent of patients with vertigo improved within 4 weeks of taking 80 mg of Ginkgo 2 times a day. Ginkgo has been found to increase blood flow to the eye. Animal studies on Ginkgo have shown significant improvement in retinal function. Scientists believe Ginkgo will show benefit to humans with these conditions as well.
Clinical studies are currently under way.
If you find your legs cramping in pain after walking a short distance or going up a flight of stairs, you may have a condition called intermittent claudication. The problem come from blockages in the arteries of the legs so your muscles can't get enough oxygen rich blood. Surgery can open up or bypass these blockages. There are also medications with potentially dangerous side effects that can help increase blood flow. Ginkgo may be another safe option.
