Also vacuity-detriment taxation damage; taxation timidity. Any pattern of severe vacuity (of qì, blood, or the organs), including notably steaming bone and consumption. The term comes from Essential Prescriptions of the Golden Cabinet (金匮要略 jīn guì yào lüè, xuè bì xū láo bìng mài zhèng bìng zhì), and was explained in The Origin and Indicators of Disease (诸病源候论 zhū bìng yuán hòu lùn) as referring to any of various qì, blood, or organ vacuity patterns on the one hand and contagious diseases such as steaming bone and corpse transmission (i.e., consumption) on the other. Since then, it has become a convention to refer to the former patterns as vacuity detriment, whereas the latter patterns are referred to as consumption. Compare vacuity detriment.
