*slow clap* this is why you shouldn't do binding/love spells on people. [sorry, just, your friend gave a prime example]
k, cleansing works best, i have some undo binding spells kicking around somewhere [need to remember which book they're in though] but like it was said above, visualize a white cord being cut. after, your friend should have a sea salt bath to purify herself. she doesn't need to wash, just visualize the water being white, and as she soaks in it, the white light enters her. this should take with it all the spells cast upon herself.
if that still doesn't work, and she doesn't want to just wait it out, you can always cast a spell to undo spells you have done. i'm sure there's some on the site, if not, i'll find one of mine and post it.
