Aikido has by its very nature definitely healing powers. Not many people seem to be too aware of this or interested in it and I know of just a few teachers that conciously incorporate the knowledge of healing into their lessons. But even if teachers do not explain it, most Aikido dojo practice some form of misogi and that in particular stimulates the healing capacity / energie.
I found it worthwhile to investigate and study this aspect of Aikido.
All the best,
