Dangers from cures limiting hospital (7)
I believe the answer is:
threats
'dangers' is the definition.
(threat is a kind of danger)
'cures limiting hospital' is the wordplay.
'cures' becomes 'treats'.
'limiting' means one lot of letters goes inside another.
'hospital' becomes 'h'.
'treats' enclosing 'h' is 'THREATS'.
'from' is the link.
(Other definitions for threats that I've seen before include "Terrifying demands" , "Expressions of intention to harm" , "Shatter (anag) - menaces" , "Statements of intentions to harm" , "Sources of danger -- shatter (anag)" .)
