Electrical stimulation unit and waterbath system

A method for providing an antifungal agent for treating a fungal infection of a nail, the method comprising:

• placing the foot including said nail infected with the fungal infection in a fluid reservoir comprising an aqueous solution, the fluid reservoir comprising a front wall, side walls and a back wall, in which each of the front wall, the side walls and the back wall are coupled to a bottom surface, the front wall, side walls, back wall, and bottom surface being sized and arranged as the footbath to receive the one or both feet, the front wall comprising a first electrode so that when the foot is placed in the fluid reservoir the first electrode is positioned in close proximity to at least one toe of the foot, and the fluid reservoir further comprising at least a second electrode on one of the sidewalls, back wall or bottom surface so that the second electrode is positioned in close proximity to the heel of the foot;
• and
• treating the fungal infection of the nail by providing a pulsed current as the antifungal agent to said aqueous solution in the footbath at a fungicidal or fungistatic amount to thereby treat the nail infected with the fungal infection, the pulsed current being provided by a source being a voltage of less than 150 volts, a monophasic waveform with pulse pairs having intervals of 150-330 microseconds, a pulse width of 5-50 microseconds, and a pulse repetition frequency of 100-200 Hz.
