Poetically add venom to poems no one trashed (8)

I believe the answer is:

empoison

'poetically add venom' is the definition.
(poetic term meaning to poison)

'poems no one trashed' is the wordplay.
'one' becomes 'I' (Roman numeral).
'trashed' indicates anagramming the letters.
'poems'+'no'+'i'='poemsnoi'
'poemsnoi' anagrammed gives 'EMPOISON'.

'to' acts as a link.

I've seen this clue in The Guardian.
