Beer gets nothing from plant (4)
I believe the answer is:
Here is my best explanation:
'plant' is the definition.
(aloe is a kind of plant)
'beer gets nothing' is the wordplay.
'beer' becomes 'ale' (I've seen this before**).
'gets' means one lot of letters goes inside another (gets can mean captures or absorbs).
'nothing' becomes 'o' (looks like zero - 0).
'ale' placed around 'o' is 'ALOE'.
'from' is the link.
(Other definitions for aloe that I've seen before include "Bitter fruit", "shrub", "Plant source of purgative drug", ". . . . vera, soothing plant", "Succulent plant (may be bitter!)", "Shrub", "Flower, maybe vera", "Succulent plant (4) 5532", "Bitter succulent plant" and "Fleshy-leaved plant".)
