Foods you can eat to clear your lungs include lilies and yams. Lily and yam are medicinal foods. Lily has the effect of nourishing yin and moisturizing the lungs (nourishing the lungs by replenishing the lung fluid), and clearing the heart and tranquilizing the mind (tranquilizing the mind by removing inner vexation and heat). It is used in treating yin deficiency and dry cough, laborious cough and hemoptysis, deficiency vexation (vexation caused by deficiency heat in the body), palpitation, insomnia, excessive dreaming and mental trance. Wind-cold cough and cold loose stools (feces thin and unformed) should not be taken. Chinese yam is used for treating spleen deficiency with little food, fatigue (tiredness), loose stools and diarrhea, lung deficiency with asthma and cough, kidney deficiency with spermatorrhea, frequent urination under the belt, and internal heat and thirst (internal heat accompanied by symptoms such as more food, more drinking and more urination). It is not suitable for those who are full of dampness (too much dampness causing fullness and discomfort in the spleen and stomach) or those who have solid evils or stagnation. If there is any discomfort, it is recommended to consult a doctor in time.
