This [formula treats] heat excess in both the exterior and interior, either from wind-heat invading a patient with preexisting internal accumulation of heat, or from an invasion of wind-heat which causes heat to lodge in both the exterior and interior simultaneously. The strong fever and chills are a sign of exterior wind-heat. Because it tends to attack the upper parts of the body, wind-heat causes dizziness and red, sore eyes. It also attacks the Lungs and causes difficulty in swallowing and nasal congestion with thick and sticky nasal discharge and saliva. Interior heat, accumulating primarily in the Lungs and Stomach, is reflected in the bitter taste in the mouth, dry mouth, focal distention with a stifling sensation in the chest and diaphragm, constipation, dark, rough urination, greasy, yellow tongue coating, and flooding, rapid or wiry, slippery pulse. This formula, a variation of Cool the Diaphragm Powder (liang ge san), is used for excess heat in both the exterior and interior. From the perspective of the six stages of disease, this formula treats a disorder which simultaneously affects the greater yang (exterior), yang brightness (interior heat), and lesser yin (focal distention with a stifling sensation in the chest and diaphragm). The source text recommends this formula for all wind-heat disorders with constipation, dark, rough urination, facial sores, and red, sore eyes, since such conditions can progress to internally-generated wind with stiff tongue or clenched jaw.* --From: Bensky & Barolet, Chinese Herbal Medicine Formulas and Strategies.
