Healing heat - picture another way (11)
I believe the answer is:
therapeutic
'healing' is the definition.
(I know that healing can be written as therapeutic)
'heat picture another way' is the wordplay.
'another way' indicates anagramming the letters.
'heat'+'picture'='heatpicture'
'heatpicture' with letters rearranged gives 'THERAPEUTIC'.
(Other definitions for therapeutic that I've seen before include "Helping to cure" , "having a good effect" , "Contributing to good health" , "Sanative" , "Curative" .)
