10 ml, 0.34 fl. oz . Frankincense was reintroduced to Europe by Frankish Crusaders. Although it is better known as "frankincense" to westerners, the resin is also known as olibanum, which is derived from the Arabic al-lubān (roughly translated: "that which results from milking"), a reference to the milky sap tapped from the Boswellia tree. Some have also postulated that the name comes from the Arabic term for "Oil of Lebanon" since Lebanon was the place where the resin was sold and traded with Europeans. Compare with Exodus 30:34, where it is named levonah, meaning either "white" or "Lebanese" in Hebrew. Frankincense was lavishly used in religious rites. In the Book of Exodus in the Old Testament, it was an ingredient for incense (Ex 30:34); according to the book of Matthew 2:11, gold, frankincense, and myrrh were among the gifts to Jesus by the Biblical Magi "from out of the East."
