Milk has the effects of nourishing lung and stomach, promoting fluid production and moistening large intestine. Studies have found that milk has a very effective therapeutic effect on peptic ulcer and habitual constipation. I have a bad stomach since I was a child. I have been drinking milk at home, saying it is nourishing my stomach. You can basically see all kinds of dairy products at home. Now my stomach is much better, and I won't feel uncomfortable eating. I think it's quite useful.
