This topic examines the functions and indications of Mingmu Shangqing Tablet and Dendrobium Nocturnal Granule. ① Mingmu Shangqing Tablet: Its function is to clear away heat and dispel wind, improve eyesight and relieve pain. Indications: Outbreak of flaming eyes, redness and pain, dizziness, itching around eyes, dry stool and red and yellow urine caused by exogenous wind and heat. ② Dendrobium luminous granule: Its function is nourishing yin and tonifying kidney, clearing liver and improving eyesight. Indications: dark eyes and blurred vision caused by deficiency of liver and kidney and hyperactivity of fire due to yin deficiency. Mingmu tribulus pill has the function of clearing away heat and dispelling wind, but its main indication is the outbreak of fire eyes with excessive fire, so we should pay attention to the difference. Mingmu Dihuang Pill can treat liver and kidney yin deficiency syndrome, but its function is to nourish liver and improve eyesight, which is inconsistent with the meaning of the question and can be ruled out. Babao Eye Powder is mainly used to treat redness and swelling of the eyes due to excessive fire in the liver and stomach.
