Otto is the term used to differentiate the steam distilled variety from the 'Absolute'. It is from the Bulgarian 'Damask' Rose. In aromatherapy applications, the Otto is more potent than the Absolute, and an even smaller amount is needed. Some perfumers consider that even fractions of a percent can do wonders. This is the oil of love, that has many psychological and physiological applications. Though the rose is renown for its fragrance, the flower actually contains very little aromatic oil by weight. Some 60,000 roses are needed to distill a single ounce of oil, or about 60 roses PER DROP, a fact which brings the seemly high cost of rose oil into perspective. There is perhaps no better essential oil for women and men than Rose oil for use in treating conditions of the reproductive system. It is highly valued in formulas for mature, dry and sensitive skin, and its tonic action on the heart appears to help relieve cardiac congestion, improve sluggish circulation, and tone the capillaries.
