Abstract: Zhang Zhongjing’s formulae have been complimented for its rigorous ingredient combination and structure. Ephedra and gypsum, used by Zhongjing as one main paired herbs, have been widely used by later generations. In this study, six classic formulae and another two extended prescriptions containing both ephedra and gypsum have been selected. Graphics were used to interpret the compatibility by visualizing the nature, flavor, meridian tropism, action, and the principles of the composition of prescriptions, etc. The fundamental structure is mainly composed of pungent-warm ephedra to regulate qi and pungent-cool gypsum to clear heat. Different compatibility proportion of ephedra and gypsum match with bitter-warm almond, developing a triangle fundamental structure to present clearing, dispersing and descending to balance the circulation of the lung qi, thus to restore the functions of the respiratory and regulating the respiratoy metaboism. Proportion of ephedra and gypsumcan be determined by weighing the balance of clearing heat and regulating qi movement. In addition, points, lines and surfaces would be used to modify the structures of the prescriptions according to the complicated pathogenesis to make flexible use of the prescriptions.

Key words: classical prescription, geometric structure, ephedra, gypsum, compatibility laws
