Perwinkle Plant- The periwinkle plant that has a significant medicinal use is the species Vinca minor, commonly known as lesser periwinkle. The plant is widely distributed across southern Europe, Netherlands, Southwestern Asia, Portugal and France. The subshrub and herbaceous plant has evergreen leaves that are used medicinally because of the active component vincamine. Vincamine is potent peripheral vasodilator that increases the lumen size of blood vessels letting blood flow more freely. This in turn increases the oxygenation of tissues, even the brain. This indole alkaloid then relieves hypertension through decreasing peripheral vascular resistance. Furthermore, it has nootropic properties that enhance memory and cognition. The interplay of vincamine in the production of neurotransmitters may be the reason for its nootropic activity.
