Interestingly... 'Frankincense resin was historically recovered by brutally flaying and stabbing the bark of the tree. Then the tree seems to bleed out of it's wounds the resin that then hardens. Resin is the most positive natural substance on the triboelectric scale and is also used in the alchemical process of making the sacrament. Some of the preparation process may require the substance to be "crucified" in a crucible where chemicals are changed by "crossing" a threshold of the chemical bonds using heat or PH value. This is the allegory of the crucifixion.'
