This is due to weakness of the spleen and stomach, or injury to the spleen and stomach after a long period of illness, or overuse of bitter cold, resulting in damage to the Yang, while the evil of dampness and heat has not yet gone, resulting in cold-heat mixed evidence of spleen cold and intestinal heat.
