A perennial member of the rose family Rosaceae, Silverweed (Potentilla anserina) has long been known for its cramp-fighting properties. It is widespread in the northern hemisphere where it is known to form a carpet of silvery leaves that shimmer in the wind. The name potentilla is Latin for mighty due to its great healing power. Anserina means “of the goose” in Latin probably because this plant grows well in areas where geese walk and “fertilize” the soil with their droppings. It is also called Silvery Cinquefoil, Crampweed, Tormentilla, Goosegrass, Goose Tansy and Five Finger Grass.
