Shaking this aphrodisiac could result in violent poo (4,6)
I believe the answer is:
love potion
'shaking this aphrodisiac' is the definition.
'love potion' can be an answer for 'aphrodisiac' (I've seen this in another clue). I'm not sure about the rest of the definition.
'result in violent poo' is the wordplay.
'result in' indicates an anagram (I've seen 'resulting in' mean this).
'violent'+'poo'='violentpoo'
'violentpoo' is an anagram of 'LOVE-POTION'.
'could' is the link.
Can you help me to learn more?
(Other definitions for love potion that I've seen before include "preparation for it" , "Aphrodisiac needed!" , "Magic drink stimulating desire" .)
