There are many who present themselves as healers, as well as many methods of treatment --- from the most primitive to what is described as the science of today. Everything has its place and time in the Universe --- the Universe in Mystical Reality being the thought process of Universal Consciousness or God. And, if everything indeed does have its place and time in human experience, inclusive of healing, then in the human expression or practice of healing there is no "one size fits all" manner of treatment or one kind of healer above all others.
From a mystical perspective, healing and healers are viewed from what in fact is really taking place. Consider, by way of example, Jesus, who had seemingly --- at least in appearance's sake --- performed miracles of healing. When credit was directed toward him, he responded, through the Christ Mind that was in him, with the words: "Why callest me good? It is not I, but the Father which doeth these good works." He spoke the great mystical Truth about healing, healers, and healing methods --- only the Universal Consciousness or God actually does the healing.
