I have just been mulling over this question in my head. I don't think that it has happened in the manga/anime or even in any fan fiction that I have read. But it is quite possible that I got this idea from somewhere. What do you think would happen if Kagome shot one of her arrows into Miroku's Kazaana. Would it heal his Kazaan? Would it at least cleanse him of the stuff that is infecting him? If Kikyou was able to cleanse him from the outside wouldn't that power be able to heal him from the inside. The Samio... DemonBees are able to infect him from the inside so what would Kagome's power do? What does anyone else think?
