" Then the LORD said to Moses, "Take the following fine spices: 500 shekels of liquid myrrh, half as much of fragrant cinnamon, 250 shekels of fragrant cane, 500 shekels of cassia—all according to the sanctuary shekel—and a hin of olive oil. Make these into a sacred anointing oil, a fragrant blend, the work of a perfumer. It will be the sacred anointing oil."
250 shekels of "Fragrant Cane" translates to approximately 6 pounds. Fragrant Cane is known to modern aromatherapists as Calamus Oil. It is extracted from the Root of the Sweet Flag, which is most commonly used by home gardeners as an ornamental grass for pond, fountain & water gardening.
500 shekels of myrhh & cinnamon together is about 25 pounds and hin of olive oil translates to probably about 4 quarts, or one gallon.
In Biblical Times I would guess that these 4 ingredients would have been macerated together for a couple months & decanted before use. I am also guessing the smaller proportion of Calamus would be not only for blending purposes but also due to the fact that it causes hallucinations in large quantities. It also has tranquilizing & antibiotic qualities and can be potentially toxic.
It has a refreshing scent & traditionally has been smoked, eaten, or brewed into a tea, decoction, extract, tincture and syrup. In Indian Aryuvedic medicine Calamus is a 'sattvic' herb, which means it feeds sexual 'kundalini' energy. Calamus has a reputation as the closest thing to a sex stimulant that nature has to offer.
And you thought you were getting a scripture lesson ..... ;)
