Lungs like moist and evil dryness, heat and evil cause yin and fluid depletion and injury to the lungs, you need to nourish yin and moisturize the lungs. In a dry climate, the human body can thus produce a lot of fluid loss of “dryness”. For example, the lungs are injured, more cough, cough in the fall, often dry cough without phlegm or gum phlegm difficult to cough, so-called “dry cough”. Nose is the orifice of the lungs, nasal dryness is particularly common after the fall, throat, pharynx are also the gateway to the lungs and lung gas channel, autumn dryness attack, often lead to dry throat, dry mouth, mute and other discomforts.
