Pig lungs can be eaten by humans and there is no harm in them! As the saying goes, you are what you eat. Eating pig lungs can cure cough due to lung deficiency and has the function of nourishing the lungs. Pig lung is a food-based drug and is not included in general Chinese medicine books. However, there are records of the medicinal use of pig lung in Li Shizhen's "Compendium of Materia Medica". Pig lung is sweet in taste and slightly cold. It can nourish the lungs, treat cough due to lung deficiency, and treat hemoptysis due to lung deficiency.
