Shamanic healing is spiritual in nature. Its techniques are not therapy as generally defined by modern psychology or medicine, and they are not a substitute for the therapeutic methods practiced by these fields. However they may serve as powerful complements to those methods.
Shamanic practitioners have a wide selection of techniques to draw upon. It is not uncommon for techniques to be fine-tuned or customized to minister to specific situations. Indeed, sometimes entirely new, or personally unique, ways of working may be shown to a practitioner by spirit teachers or helpers.
While anecdotal and experiential evidence concerning the efficacy of given shamanic techniques may be extensive, the non-material nature of shamanic work, as well as the vast array of possible responses to it, makes empirical documentation of effectiveness difficult. (How can we prove that a person’s soul has returned to them beyond their own testimony that they feel it has?) Therefore no definitive representations can be made as to any physical, mental or emotional benefits to be gained from using these ancient methodologies. Those seeking shamanic assistance are encouraged to determine for themselves if this kind work is of personal benefit.
Here are links to information about some of the most common and powerful methods of shamanic healing. There are, of course, many others. I hope this information is helpful to you.
