Natural healer (4)
I believe the answer is:
aloe
'natural healer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aloe that I've seen before include "Bitter fruit" , ". . . . vera, soothing plant" , "Fleshy-leaved plant" , "Succulent plant (may be bitter!)" , "shrub" .)
