There can be theraputic rituls. Like any kind of therapy, they work best if the person is willing to face their issues. I've known people to seek more traditional/on-going therapy from insights they've gained about themselve in rituals.
When they involve more than one person, a deep level of trust in the others and trust in non-judgement is essential between the people involved.
The thing to be careful of is that you are really addessing and working on underlying issues, which can be hard work no matter which method is used. And sometimes just needs an outsider to help you get out of your head. You don't want to be too easily led to think that progress has been made simply because you or another person feels good after a ritual, although the positive action and emotions may also be helpul. You just want to avoid making ritual/spiritual healing a crutch or a band-aid to a symptom.
I also use Reiki which I would say similar things about it as well. Not a miracle cure, but certainly can make a person feel more balanced or stronger and thus better able to tackle issues, make a positive change, etc.
