OK Essential oil's has been extracted for 1000 years. Its done pretty easily but does take a lot of time and plant material to produce a small quantity of oil.
But Pure 100% essential is very expensive. And making it yourself is not very hard.
Pretty much steam it forced through plant material, breaking apart the oil molecules from the rest of the plant material.
The steam/oil's are then carried through a condenser, were the water and oil are separated though a change in temperature.
Then collected in a vessel, the oil settles on the top of the water now called Hydrosol. Then the oil is siphoned off the top of the water.
