A therapeutic apparatus for providing therapeutic benefits to an immersed body part due to contact with a heated or unheated homogenous medium. The therapeutic apparatus includes at least two vibration generators for generating two waveforms at two distinct areas of the vibratory vessel, where the two waveforms are converging on each other and combined together to create a constructive and destructive pulse waveform having a larger constructive amplitude than the amplitude of the original wave and a smaller destructive amplitude than the amplitude of the original wave for providing a constructive and destructive pulse wave massaging effect to the body part of the user immersed within the homogenous medium contained within the vibratory vessel.
