To determine whether it is phlegm-dampness or phlegm-heat, you can look at the color of the phlegm, the accompanying symptoms, and the tongue and pulse. 1. The color of phlegm: phlegm-heat is mostly yellow, while phlegm-dampness is mostly white. 2. Accompanying symptoms: phlegm heat is often accompanied by heat symptoms, such as dry mouth, bitter mouth, red face, sore throat, blood in phlegm, etc., while phlegm dampness has no heat symptoms, mainly manifested as chest tightness and epigastric plumpness, dullness (lack of appetite, reduced food intake) and low food intake, lack of strength in the limbs, mental fatigue, and unshapely stools. 3. Tongue and pulse performance: phlegm-heat is characterized by red tongue, yellow moss and slippery pulse, while phlegm-dampness is characterized by light red tongue, white moss and slippery pulse. If phlegm-heat or phlegm-dampness is present, the clinician should be consulted for diagnosis and treatment.
