Uses
Lesser periwinkle (Vinca minor) has a number of therapeutic uses, for instance it is used in the form of an astringent as well as an herb to stop hemorrhage. The astringent attribute of lesser periwinkle makes the herb an effective mouthwash for treating canker sores, sore throats and gingivitis. Following the discovery that the leaves of lesser periwinkle enclose an alkaloid known as vincamine, this herb has been employed in the treatment of arteriosclerosis as well as for curing dementia owing to inadequate flow of blood to the brain. Also, lesser periwinkle is very useful and effective in treating nosebleeds, internal bleeding and heavy menstrual bleeding

In traditional medicine, the dried herb of lesser periwinkle (its aerial parts and, occasionally, the entire Vinca plant) is employed to augment blood circulation, especially to the brain, improve metabolism in the brain as well as to cure cardiovascular ailments.
