"Bian Que Xin Shu" and so on. "Bian Que Xin Shu", "Emperor's Internal Classic", etc. all have records of wrapping medicine therapy. In ancient times, imperial doctors treated the emperor. They crushed the Chinese herbal medicine and wrapped it with silk to make a six-inch wide belt to tie around the emperor's waist. During this time, it can be used to treat a variety of diseases and prolong life. Because it was exclusive to the emperor, it was called the Nine-Five Wrap Medicine.
