A method and device is provided for extracting oils, from plant material, of the type used for aroma-therapy or cooking and the like. The device comprises a container having a single inlet aperture in a top end and a plurality of outlet apertures in a bottom end opposite the inlet aperture. The plant material is placed in the container and supported above a suitable receptacle. An organic solvent having a boiling point below ambient temperature, such as butane, is dispensed from a pressurised vessel into the inlet aperture of the container and is allowed to drain into the receptacle through the outlet apertures after forming a solution with the oils of the plant material. The organic solvent is then permitted to evaporate from the solution in the receptacle leaving the extracted oils in the receptacle.
