All fluids, when placed within a Kukharev region at a moment of gravitational resonance, form vibrations of different frequencies within themselves. If, at the same moments of gravitational resonance, forced oscillations of the same frequency are provided as a treatment on a living organism, a double resonance is formed within the fluid, and a sharp increase in the amplitude of oscillations within the fluid formed as a result of the double resonance in turn causes the destruction of the fluid. The method is determined utilizing Kukharev region data on the particular fluid desired to be destroyed or otherwise removed from the living organism. By further fine-tuning the forced oscillation (i.e., the directed radiation), the natural oscillations of the base fluid can be further adjusted to modify the fluid's properties.
