The extract of periwinkle plant,
vinpocetine, is one the smart drugs to hit the United States.
Vinpocetine was originally researched by Hungarian doctors and was found
to reduce memory problems, dizziness and the effects of stroke. It helps
the brain use glucose and oxygen more easily and boosts some of the
chemicals necessary for normal transmission of information. It also
helps the brain retain information. It protects the nerve and brain
cells from damage due to oxygen starvation and eases the blood flow by
reducing its stickiness.
have been over 100 trials on the effects of vinpocetine and most of
these show some benefits. In one report, which studied 3,000 patients
who took the supplement, 70% said that they experienced 'some
improvement'. No side effects were observed.
Vinpocetine is used in the treatment of
dizziness, vertigo anxiety, difficulty in sleeping and transient
ischaemic attacks (TIAs), as well as with memory problems. It may also
help in cases of macular degeneration, glaucoma and hearing problems.
The suggested use is one or two 5mg
tablets three times a day, but this should be continued for at least a
year for maximum results.
