Myrrh is mentioned in the Bible (Psalm 45:8; Song of Solomon 4:14) and is believed to have been a mixture of myrrh and the oleoresin labdanum. One of the three gifts the Magi brought to Jesus Christ (Matthew 2:11) was myrrh. Myrrh gum resin was also used as a stimulant tonic and is even used today as an antiseptic in mouthwashes as well as to treat sore gums and teeth.
Pieces of Aquilaria wood lacking the dense and dark resinous agarwood caused by infection
Agarwood or oodh (or just agar) is a dark resinous heartwood that forms in Aquilaria and Gyrinops, trees (large evergreens native to southeast Asia) when they become infected with a type of mold. Prior to infection, the heartwood is relatively light and pale coloured, however as the infection progresses, the tree produces a dark aromatic resin in response to the attack, which results in a very dense, dark, resin embedded heartwood. The resin embedded wood is commonly called gaharu, jinko, aloeswood, agarwood, or oud (not to be confused with 'Bakhoor') and is valued in many cultures for its distinctive fragrance, and thus is used for incense and perfumes.
