What is the best thing to eat to maintain the lungs?

Disease analysis: Hello, in terms of diet, blood products such as pig blood have the function of clearing away lung heat. In addition, tremella, mushrooms and other fungi are also good, all of which are suitable for lung diseases. Pear is a good choice among fruits. Chinese medicine can also be used instead of tea, such as lily and Ophiopogon japonicus. I wish you the best of health! Suggestion: As far as I know, the best way to maintain the lungs is in places with abundant oxygen, such as deep forests and Woods, which are called oxygen bars.
