Aromatic water and essential oil extraction process from vegetable matrices, in the absence of solvent, in which the vegetable matrix is placed under vacuum and heated to a temperature higher than the water boiling point, in which the water that is obtained from the evaporation comes exclusively from the vegetable matrix as a result of the breaking of the cell structures, in which vapors condense by lowering the temperature, in which after condensation in a collector water and essential oil are recovered, characterized by the fact that the vegetable matrix is homogenized with the addition of a salt, that the heating is performed under vacuum with a hot bath.
