What are some alternatives to disposable pads and tampons?

Not on the rag again: Yes, women actually used rags and washed them out as an alternative to the 'modern day" tampons and pads. One old remedy that still works is the plastic vaginal cup which is inserted into the vagina and needs to be emptied occasionally to catch the menstrual flow. I guess that is "going green" these days with a "red event.".
