What Is "Bird Nest" in Traditional Chinese Medicine?

To most people in the modern world, the term "bird nest" is anything but extraordinary. A bird's nest is a place where birds keep their eggs and protect their young until they are big enough to take off in flight on their own. They are common and ordinary so no one thinks too much about them unless one comes falling out of a tree in front of them or one is seen high up in a beautiful tree.kids babies baby child
