Commentary states: The essence and qi of the five zang organs and six fu organs all ascend to pour into the eyes (Mù, eyes), which is where all meridians converge. After convalescence from Cold Damage (Shānghán, a category of febrile diseases caused by cold pathogenic factors), residual toxins remain uneliminated, invading internally within the Liver (Gān, liver). Evil heat rushes upward, causing stagnation and obstruction in the blood vessels, resulting in redness and pain in the eyes. In severe cases, sores may form, or nebulae (yì mó, opacities on the eye surface) may develop, obscuring the pupil. Treatment should focus on cooling the Liver meridian to dissipate heat and toxicity.
