This is a sign of insufficient body fluid. Chinese medicine believes that all muscles in the human body are managed by the spleen. Spleen belongs to soil in the five elements. Lips are also a piece of meat, and its dryness is like the dryness of the earth and land in nature, so the way is to produce fluid to moisten dryness and reduce stomach fire. The simplest thing is that you buy some pears, cut them into pieces and drink them twice a day for three or four days. Until your lips are dry.

But your lips are not only dry, but also cracked, which means that you may still be constipated and the wall of the large intestine is dry, so why not bother to run some health tea every day:

You can buy some Polygonatum odoratum, cassia seed, poria cocos and licorice in the wet or Chinese medicine shop. Soak in water every day, and you can eat fried radish or tremella lily soup at night.
