中药升降浮沉学说是中药学基本理论的重要内容。这一理论虽创立于金、元时期，实导源于《内经》气机升降学说，并首先在张仲景诸方中得到具体应用。以李时珍为代表的明清医药学家为这一理论增加了许多新的内容，使之更臻完善。是古代众多医药学家集体智慧的结晶，目前正愈来愈引起人们的重视。 The theory of lifting and floating of Chinese medicine is an important part of the basic theory of Chinese pharmacy. Although this theory was founded in the period of Jin and Yuan Dynasties, it was actually derived from the theory of the rise and fall of the Internal Classic, and it was first applied in Zhang Zhongjing’s Zhu Fang. The medical experts of the Ming and Qing Dynasties, represented by Li Shizhen, added many new contents to this theory and made it more perfect. It is the crystallization of the collective wisdom of many medical scientists in ancient times and is now attracting more and more attention.
