The small intestine is the fu-organ of the heart. The heart and the small intestine share an exterior-interior relationship. When heat pathogenic factors accumulate in the heart and persist for a long time without being resolved, sweating depletes body fluids (Jin-Ye), leading to insufficiency that fails to nourish and irrigate. Consequently, toxic heat flows into the small intestine, causing urinary obstruction.
For epidemic febrile diseases (Shi-Qi) presenting with alternating chills and fever, heaviness in the four limbs, loss of taste, sensation of regurgitation and blockage in the chest, and urinary obstruction, it is appropriate to administer Chi Fu Ling San (Red Poria Powder).
