Astral Healing is only useful in roughly the same way that Sermon of Courage is: you only make morale checks when you take more than half as many "wounds" in a unit as there are units, and a "wound" only counts if it drops a given unit below 80% health. Thus, Astral Healing can boost units taking arrow fire back up above 80% and prevent them routing, as well as helping them survive a bit more.

Very situational, but I guess it could help under heavy arrow fire or BEs like Fire Storm. I've never used it.
