Adore getting hold of a good herb (6)
I believe the answer is:
lovage
'herb' is the definition.
(lovage is a kind of herb)
'adore getting hold of a good' is the wordplay.
'adore' becomes 'love' (I've seen this before**).
'getting hold of' indicates putting letters inside.
'a good' becomes 'ag' (I've seen this in other clues).
'love' placed around 'ag' is 'LOVAGE'.
(Other definitions for lovage that I've seen before include "Parsley relative - a glove (anag)" , "Salad plant from a glove?" , "liquor" , "Salad plant from southern Europe" , "Herb made from a glove" .)
