                                The term "periwinkle" can refer to both a genus of flowering plants (*Catharanthus*) and an edible marine snail (*Tympanotonus fuscatus*), a distinction crucial for understanding if periwinkle has cholesterol. A recent study confirmed the edible mollusc contains a small amount of cholesterol.
