Says no physical harm comes from talking therapy (14)
I believe the answer is:
psychoanalysis
'talking therapy' is the definition.
'psychoanalysis' can be an answer for 'therapy' (I have seen 'Mental therapy' mean 'psychoanalysis' so perhaps 'therapy' could also mean 'psychoanalysis'). I'm not sure about the 'talking' bit.
'says no physical harm' is the wordplay.
'harm' indicates an anagram (I've seen 'harmed' mean this).
'says'+'no'+'physical'='saysnophysical'
'saysnophysical' with letters rearranged gives 'PSYCHOANALYSIS'.
'comes from' is the link.
Can you help me to learn more?
(Other definitions for psychoanalysis that I've seen before include "mental treatment" , "Method of treatment pioneered by Freud" , "Freudian theory" , "System of mental therapy" .)
