In Chinese medicine, there are two types of phlegm: visible and invisible. Visible phlegm is the one you see when you cough or sneeze. Invisible phlegm is the one you can't see. In Chinese medicine, phlegm is not just something you feel in your throat or contained in the lungs. It can go anywhere in the body and creates lymph nodes or nodules. Phlegm is "turbid fluid." It can cause full sensation, dizziness, vomiting, etc. It can even "mist the mind" and cause mental issues.
So what causes phlegm? Dairy products are known to cause phlegm. You will want to avoid them when you're sick and minimize them even when you're not sick. Sugar is another contributor to phlegm formation in the body. Sugar here includes natural fruit sugar, organic pure cane sugar, artificial sweetener, and sugar of any kind. So minimizing these is wise.
