Lichah

Lichah, derived from the Hebrew word ליחה, typically refers to phlegm or mucus, particularly that produced in the respiratory system, such as the lungs or throat. It can also refer to sputum, which is phlegm that is coughed up. The term is primarily used in medical or biological contexts when discussing respiratory illnesses, diagnostic procedures involving sample collection, or the characteristics of respiratory secretions. While the word "mucus" can broadly refer to any viscous secretion, "lichah" specifically emphasizes the respiratory origin and often implies a pathological state, such as an infection or inflammation. The appearance (color, consistency) of lichah is often examined for clues regarding the underlying cause of a respiratory condition.
