Unless you mean Aspidistra elatior, common name Cast Iron plant. If you do, you can split it in half and repot the sections, its probably looking sick because its run out of root room.
A photo would be very useful.

wont be aspidistra if its six feet tall. I suspect it is the false castor oil plant. you can prune it with success. so yes prune it back and make sure you give it a decent feed.

If you want advice about cutting back it would help if you could add a photo to your question.
