6 min read
Periwinkle is a common name that refers to both the medicinal plant species, like the Madagascar periwinkle (*Catharanthus roseus*), and the edible marine snail (*Littorina littorea*). However, the minerals in periwinkle vary dramatically depending on which type is being discussed, with the sea snail offering a rich source of dietary minerals, while the plant is known for its potent alkaloids rather than its mineral content.
