Native to southern and central Europe and western Asia, it was
introduced and naturalized in the northeast, midwest, and pacific northwest US.
This creeping periwinkle blooms early spring to summer. It is sometimes considered invasive because it can outcompete native plants by forming dense mats thriving in disturbed areas, woodlands, forest edges, and shaded areas. Because it grows so easily it is often used for erosion control and ground cover.
It does have medicinal benefits and
although not edible raw due to toxic alkaloids, the main alkaloid, vincamine, has been shown to have an effect on circulation and cognition, improving mental clarity, memory and cognition.
It acts as a mild vasodilator, enhances blood flow to the brain,
and is used for conditions like poor circulation, varicose veins and hemorrhoids.
Used in decoctions and extracts for migraines, headaches and vertigo,
it has antioxidants and anti-inflammatory effects.
Leaf extracts were applied traditionally to reduce inflammation and to support overall wellness.
It is also used topically on minor wounds and skin irritations.
