Miloš Oberonović, a Serbian revolutionary who became the first Prince of Serbia, was convinced that “white kidneys” (Serbian for testicles), increased sexual potency and had aphrodisiac powers. He also believed that the white kidneys, (best eaten cooled and “live” i.e. raw), were not effective unless there was a harmonious combination of psyche and physiology. After eating, Prince Miloš often engaged in physical activity as a means to expend the positive energy and various hormones and minerals taken into his body. Wink, wink.
