Tribal priest-doctor (6)
I believe the answer is:
shaman
'tribal priest-doctor' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for shaman that I've seen before include "Sorcerer" , "Spiritual healer" , "16 21 [INDIAN IMPORT]" , "Tribal medicine man" , "Medium between the visible and spirit worlds" .)
