Since his pharmacutical rep certainly won't tell him about Vinpocetine, your doctor's probably not going to inform you of this miracle. But there's plenty of info on this subject on the web.
For starters, Vinpocetine (pronounced vin-poe-suh-teen) is derived from the common Periwinkle plant, vinca minor, a shade-loving flowering ground cover found in many parts of the U.S. A prescription is needed to purchase Vinpocetine in Europe and Japan. Thank goodness, it can be purchased in the U.S. at most health food stores and online.
Vinpocetine was first extracted in the late 1960s. It's primary action is as a vasodilator. According to www.drugs.com:
The scientific literature contains numerous studies and investigations on the pharmacological and biochemical actions of vinpocetine. The various mechanism of actions include: 1) effects on brain circulation and oxygen utilization without changes in systemic circulation; 2) increased tolerance of the brain to vascular hypoxia and ischemia; 3) anticonvulsant activity; 4) phosphodiesterase-1 inhibition; and 5) lowering of blood viscosity and inhibition of aggregation of thrombocytes.
Translation: Vinpocetine's ability to increase blood flow in the brain seems to cause a tempory significant muting of tinnitus. Vinpocetine also seems to protect ears from damage that would otherwise lead to deafness or tinnitus.
There's not been enough studies of Vinpocetine to determine precisely how it quells the buzzing in my head. I'll leave that dilemma to the researchers. All I know is it works.
