I had a question about Nynaeve's new healing. In the previous books, don't we have a forsaken refure to the AS healing as a crude battleground version of healing? Then when Moraine is going to heal Rand the "old" way, she asked him to embrace the source. She explains the healing takes less out of the body that way.
When Nynaeve used her new healing on the kid that is coughing, she makes a point to say he will need food. She says that she will follow up on the parents to make sure they won't sell the extra food she is going to arrange.
So my question is, if the new healing still drains the body and requires lots of food, why is it better than the old healing. Was this something over looked? Does the new healing infact require power from the body or not.
