Producing physical symptoms of mental origin (13)

I believe the answer is:

psychosomatic

(Other definitions for psychosomatic that I've seen before include "(Of physical illness) caused by mental factors" , "Illustrative of 'mind over matter'" , "Relating to the interaction of mind and body" , "(Of a physical illness) having a mental basis" , "Showing effect of mind over matter" .)

I've seen this clue in The Times.
