ABSTRACT
We retrieved and analyzed the articles with the subject term words or key words of the "cupping spot" from January 1, 1990 to May 20, 2018. The negative pressure, cup-retaining time, temperature and the other factors about cupping spot were compared. There was a single stimulus for the negative pressure and cupping time. Pressure and time, pressure and temperature could be considered interactively, and the best group was on research. The color standard of canister spot diagnosis had not been unified, which could be analyzed from its color characteristic and color spectrum. At present, there is no agreement on the measurement of pressure and temperature, selection criteria of subjects, etc. The experimental researchmethods on the spot are becoming more and more diverse, with modern instruments for cupping spot on clinical efficacy and biological mechanism research.
