Reviewed the main methods of using essential oils in aromatherapy, medicine, food and pharmaceutical industries. Formulated the concept of quality essential oils that covers their effectiveness and harmlessness. Found factors that affect the main warehouse oils and factors, that depends on the content of individual substances in essential oils. Set forth basic indicators of the quality of essential oils and the conditions of getting from plants. Described the such problem of the quality of essential oils as falsification.

At the frequency range up to 100 MHz the real dielectric with permittivity e and conductivity λ simulated by twoterminal element of the electric circuit with complex impedance Z~ or complex conductivity L ~ , in which interaction of electromagnetic fields with the investigated substance is provided. The values of real e ¢ and imaginary e¢ parts of the complex dielectric constant e e e ¢ + ¢ = * is calculated based on the geometric factors and measured values of Z~ and L). In a simplest case two-terminal element represents as a parallel or series connected capacitor Cx and resistor Rx.
