Discourse states: The spleen and stomach inherently possess damp-heat, or it arises from excessive drinking and overeating during the great heat of summer. Excessive sexual activity draws heat pathogens into the Kidney. Dampness and heat attack each other, leading to difficult urination. The lower abdomen becomes hard and distended; damp-toxins flow and scatter within the muscles, causing yellowing of the limbs, body, and face. Hence, it is called Nulao Dan (Jaundice caused by sexual exhaustion). However, its manifestations may also include blackening of the forehead, slight sweating, heat in the palms and soles, onset at dusk, urgency of the Bladder, and free urination. Treatment should be tailored to each specific syndrome.
