olibanum

Borrowed from Medieval Latin olibanum, Late Latin libanus, from Latin oleum libani (“oil of Lebanon”), from Ancient Greek λίβανος (líbanos, “frankincense (Boswellia carterii, now Boswellia sacra)”), from a Semitic source. See the Semitic root lbn لبن‎, meaning "white". See also (Biblical Hebrew לְבוֹנָה‎ (l'voná, “frankincense”), Arabic لبان‎ (lubān, “frankincense”)). Compare benzoin.
