The rustyback fern was already mentioned by the great Greek physician, pharmacologist, botanist, and author Pedanius Dioscorides in the 1st century A.D., though with the name of scolopendra due to its resemblance to centipedes, small reptiles that also lived in old walls and rocks. Galen called it Splenio since he thought the plant could reduce the volume of the spleen. Rustyback has been used since ancient times, and though it is not an outstanding plant in terms of its properties, it is still utilized.
