shabbat 67

for healing one might resort to all sorts of strange, weird and wonderful remedies
evoking the burning bush, appealing to angels, send away demons

but only effective cures are permitted.
not crazy ones like those superstitious idolatrous Ammorites. (who have some very strange cooking methods)

(list of various cures and remedies include carving and reciting verses about the burning bush to treat a fever, calling to various angels and demons, and what is permitted to be carried on shabbat as they have effective healing - locust egg, splinter from a crucified/hanging post, fox's tooth.... for english translation of this talmud page, see here)
