I would suggest meditation but I don't know her personally
so she may not want to do it.
Yet again I don't know whats wrong with her.
It's possible that her chakras may even be malfunctioning or blocked.

There's a good page about navel chakras(orange).
If you scroll down there is links to info about other
chakras including the solar plexus(yellow).
