Vinpocetine is a periwinkle plant extract (Vinca major) that improves brain
function. It has been used medicinally in Europe since 1983.
Vinpocetine improves cerebral circulation by dilating the arteries of the brain but does not dilate other blood vessels..
Vinpocetine can prevent the occurrence of stroke. Vinpocetine can prevent much of the damage that occurs following stroke if administered immediately following stroke.
dilates the arteries of the brain but
does not dilate other blood vessels
improves the brain's utilization of glucose.
improves the brain's utilization
accelerates the rate of learning in animal studies by up to 40%.
increases the length of time that short-term memory is retained.
improves circulation to the eyes
thereby improving vision and eyesight disorders.
improves impaired hearing and improves inner-ear problems.
improves Tinnitus (ringing in the ears) and Vertigo (dizziness).
can prevent stroke and mitigate damage in the aftermath of stroke.
can block the action of drugs
that disrupt memory.
improved the vertigo (dizziness)
of 77% of the patients in one study.
improves the flexibility of red
blood cells and may thereby help to prevent strokes.
