阳病病在皮肤、络脉部,而在"从巳至未上(9∶00-15∶00)",即日中之时,其应为夏,人体正气盛于络脉、皮肤,此时太阳之邪易解。阳明病病在肠胃之腑,而在"从申至戌上(15∶00-21∶00)",即日入之时,其应为秋,人体正气盛于腑,则此时阳明之邪易解。少阳病病在分肉,而在"从寅至辰上(3∶00-9∶00)",即平旦之时,其应为春,人体正气盛于分肉之间,则此时少阳病易解。三阴病病变部位在五脏部分,夜半人体正气入脏,所以三阴病欲解时均在夜半之中,即太阴病亥至丑上(21∶00-3∶00);少阴病欲解时,从子至寅上(23∶00-5∶00)。厥阴病欲解时,从丑至卯上(1∶00-7∶00)。三阴病的欲解时未能完全重合,而是逐个向后推一个时辰,这与少阴病、厥阴病的特点有密切关系。
Taiyang disease locates in the areas of the skin and collateralls. The time between 9: 00 and 15: 00 is the period when the sun is risen,corresponding to summer. During this time,healthy qi is exuberant in the collaterals and skin and the pathogenic factors at the stage of taiyang are easy to be eliminated. Yangming disease locates in the viscera of intestines and stomach. The time between 15∶00 and 21∶00 is the period of sunset,corresponding to autumn. During this time,healthy qi is exuberant in the viscera and the pathogenic factors at the stage of yangming are easy to be eliminated. Shaoyang disease locates between the muscles. The time between 3∶00- 9∶00 is the period of daybreak,corresponding to spring. During this time,healthy qi is exuberant between the muscles and the pathogenic factors at the stage of shaoyang are easy to be eliminated. Three yin diseases locate in the five zang organs. Healthy qi enters zang organs during midnight,so three yin diseases tend to abate during midnight. Specifically,taiyin disease tend to abate during 21∶00- 3∶00,shaoyin disease during 23∶00- 5∶00 and jueyin disease during 1 ∶00-7∶00.
