Holy anointing oil
The Holy Anointing Oil described in Exodus 30:22-25 was created from 500 shekels (about 6kg) of myrrh, half as much (about 3kg) of fragrant cinnamon, 250 shekels (about 3kg) of fragrant cane (kanehbosm, variously translated as cannabis or calamus), 500 shekels (about 6kg) of cassia, and a hin (about 4L) of olive oil.
Since the amount of spices would clearly overwhelm the olive oil, it is thought that these measures were of the original spices that were then distilled down, by "the art of the apothecary", to essential oils. Because there is no record of how the Jews rendered oil from their spices, it is unclear as to how much oil would have made up the final mixture.
The holiness of the oil was protected by the ceremonial law, which prohibited its use in anything but the rites of the temple, on threat of banishment from among the Jewish people.
