Frankincense and Mirth
A conservative blog for peace links to some good news for us traditionally-mided religious folk and others — Burning Incense Is Psychoactive: New Class Of Antidepressants Might Be Right Under Our Noses. "Religious leaders have contended for millennia that burning incense is good for the soul. Now, biologists have learned that it is good for our brains too."
Said Hebrew University's Raphael Mechoulam, one of the researchers, "In spite of information stemming from ancient texts, constituents of Bosweilla [from whose resin frankincense is made] had not been investigated for psychoactivity." He continued, "Apparently, most present day worshipers assume that incense burning has only a symbolic meaning."
The Catholic Encyclopedia of 1917 instructs us, "Incense, with its sweet-smelling perfume and high-ascending smoke, is typical of the good Christian's prayer, which, enkindled in the heart by the fire of God's love and exhaling the odour of Christ, rises up a pleasing offering in His sight (cf. Amalarius, 'De eccles. officiis' in P.L., CV)."
