Zorba:

Do you know what language the 'kartook' is from? Moringa oliefera derives from the Indian language Tamil, so, does the 'kartook' also come from India? A photo, or description would also help to ID the plant easier.

My gut feeling from your brief description is that maybe it is Curry-Leaf? I could easily be wrong (make that probably am wrong), but I have posted a link below just in case.
