My, this is an interesting development. Rabbi Rephoel Szmerla's book Ki Ani Hashem Rofe'acha, which was published in English under the title Alternative Medicine In Halacha, has been banned. The letters of condemnation were written by a range of rabbonim, and are accompanied by letters of retraction from some of those who wrote approbations, along with general letters of condemnation of energy healing and Eastern medicine (note that this presumably not preclude the legitimacy of certain evidence-based non-Western medicine). You can download the collection of letters from some twenty rabbonim, at
