Vasodilatory action, Improves brain blood flow




     Vasodilatory action measured by an inhibition of the phosphodiesterase activity and increase in the levels of AmpC, with an increase of the blood flow by diminishing the vascular resistance.


     Antiplatelet action.


     Improvement of the hemorheological conditions in the microcirculation upon increasing the deformability of the erythrocytes.


     Brain cells' increased tolerance to hypoxia (lack of oxygen in the brain) and/or ischemia (permanent or transitory decrease of blood flow).


     Increase in the levels of oxygen and use of glucose in the neurons.


     Improvement in terms of production of neurotransmitters such as dopamine and noradrenaline, to which its nootropic effect has been attributed.





Vinpocetine is a semisynthetic alkaloid of Vincamine (ethyl ester of Apovincamine).




Vincamine production process is based on synthesis from tabersonine of the Voacanga africana.




Voacanga Africana



Voacanga Africana, a West African tree can give you mild trip and let you have hallucinogenic experience. It is very popular among the people who seek experimental experiences. The tree is quite easy to grow, within the confines of your garden. With a height up to 30 feet, and leaves up to 30 cm long, the tree bears yellowish flowers when fully matures, ultimately turning into berries with yellow seeds. Its roots, barks and seeds contain a little amount of Ibogaine.




Traditional medicinal uses


Voacanga has a broad range traditional medicinal uses. In Cote d’ Ivore this plant is used against leprosy, diarrhea, generalized edema, convulsions in children, madness, as a diuretic, and infant tonic. A decoction of the stem bark and root is used in the treatment of mental disorders and the latex is applied to carious teeth. The decoction of the bark is considered an analgesic and is added to embrocating mixtures used as pastes during fracture repair. Bark and root decoctions are also used to treat cardiac spasms. The fruit decoction is used as a disinfectant, and the leaf decoctions to treat asthma to children. In southeastern Nigeria the plant is featured in many healing rituals, including some to in­duce hallucinations and trances in religious rituals. In Congolese traditional medicine preparations of extracts containing V. africana are used as anti-amoebial. Intestinal amoebiasis is one of the current diseases in tropical regions causing diarrhea. It has been reported that V. africana has active activity against Entamoeba histolytica in vitro
