In wild area vole's destroyed plant (4,4)
I believe the answer is:
aloe vera
'plant' is the definition.
(Aloe vera is an example)
'in wild area vole's destroyed' is the wordplay.
'in' is an insertion indicator.
'wild' is an anagram indicator.
'destroyed' is an anagram indicator.
'area' is an anagram of 'aera'.
'vole' is an anagram of 'loev'.
'aera' going around 'loev' is 'ALOE VERA'.
(Other definitions for aloe vera that I've seen before include "Medicinal plant" , "Cosmetic substance" , "Plant product used in some cosmetics" , "Mediterranean plant whose thick leaves give off a soothing juice" , "cosmetic juice" .)
