Spiritual healer's bogus article (6)
I believe the answer is:
shaman
'spiritual healer's' is the definition.
(a shaman is a healer)
'bogus article' is the wordplay.
'bogus' becomes 'sham' (I've seen this in other clues).
'article' becomes 'an' (indefinite article).
'sham'+'an'='SHAMAN'
(Other definitions for shaman that I've seen before include "who practises a form of spiritualism?" , "Asian medicine man" , "Witch doctor" , "Doctor-priest working by magic" , "Spiritual healer" .)
