Born with money? Supplier of beneficial oil (4)
I believe the answer is:
neem
'oil' is the definition.
(I have seen 'Aromatic oil' mean 'neem' so perhaps 'oil' could also mean 'neem')
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for neem that I've seen before include "Exotic tree" , "Aromatic oil" , "Indian tree yielding medicinal oil" .)
