We have a frum Chinese Giyores here who believes that she can be healed by a chinese healer with cans – Bankes. The woman healer does some things like getting feathers out of a person or soapy water, as part of her therapy. i don't know if it is done by magic – achizas einayim or what. The asker is concerned because the healer is a Buddhist and she does not know if she uses Avoda Zara in her work but she really believes in her ability to heal.
Can she use her?
Healing through cups is recognized as having therapeutic value. (Shulchan Aruch, O.C. 328:43; Responsa Tzitz Eliezer 8:15) However, it should not serve in lieu of the current, accepted medical practice, but only as complementary to it.There are three halachic concerns regarding the use of feathers: magic, idolatry, and "darkei ha’emori." (See article by Rav Shlomo Aviner (Heb.) "Refuah Mashlima Mistis L'mechetza" in Assia, 75-76)
"Magic" is assumed nowadays to be done through sleight of hand, and is perceived as such by most observers, so does not pose a prohibition. Furthermore, it is not being done by the Jew, but by the gentile practitioner. (See Shach Y.D. 179:1)Healing by an idolator is permitted, so long as he does not pose physical danger and does not mentioned idolatry in context of the healing. Thus, although the practitioner is Bhuddist, it is permitted to continue treatment if the healer does not invoke Bhudda in this context (Y.D. 155:1).
There may be an element of darkei ha’emori involved, but this is permitted in the medical context. (O.C. 301:27) Furthermore, this is not recorded as an established form of "darkei ha’emori."Therefore, the woman can continue treatment with the healer, in conjunction with classical medicine, if the healer does not invoke the name of Buddha (or other idols) in the treatment.
