Chinese Herb “Ban lan gen”

Jesse is sick (again!!). Now we have two kids. I need his help. He cannot be sick that often. He needs to build up his immune system. I have asked around locals how they prevent catching cold. Their answer was having ”Ba lan gen” tea (Echinacea is not popular). I went to a local pharmacy and bought the tea. It is a little bit bitter but mostly tastes like brown sugar water. I looked at internet about bal an gen. It is Isatis root to remove toxic heat, to reduce heat in blood, and to soothe the sore throat. Jesse and I will have this tea every day from now on. We will see the result over this coming winter….
