试析营气与卫气的清浊、逆顺

Discussion on clear-turbid and sequential-reverse of nutrient qi and defensive qi

清浊与逆顺是对营气与卫气属性的进一步揭示。清浊揭示了营气与卫气的来源及活动区域。五脏法地为阴、清,营血出五脏,走脉中,故"清者为营"。六腑象天为阳、浊,卫气出六腑,走脉外肌肤腠理,故"浊者为卫"。顺逆揭示了营气与卫气活动区域及方式的不同:营气在脉内循十二经络顺行,日阳的时候随卫气由内而外,夜阴的时候携卫气由外而内,三阴脉三阳脉相贯,如环无端。卫气乃水谷之悍气,其日阳由五脏径出于目,目张而阳气散,夜阴入五脏。清阴营气、浊阳卫气相随乃为顺,清浊相干则为逆,逆则为病。

Clear-turbid and sequential-reverse is a further revealing of the properties of nutrient qi and defensive qi. Clear-turbid revealed the source and activity area of nutrient qi and defensive qi. The property of five zang viscera which modeling earth belongs to yin and clear, and nutrient-blood comes out from five zang viscera, and runs in the vessels, so the property of nutrient qi is clear. The property of six fu viscera which modeling heaven belongs to yang and turbid, and defensive qi comes out from six fu viscera, and runs in striae and interstitial space which out of the vessels, so the property of defensive qi is turbid. Sequential-reverse revealed the activity areas and manners of nutrient qi and defensive qi. Nutrient qi within the vessels and runs along with the twelve regular channels, it runs from the inside out go after with defensive qi during day, and it runs from the outside in led defensive qi during night. Three yin meridians and three yang meridians links end to end like a cyclic annular. Defensive qi is the ‘Hanqi' from essence of water and grain, which out of eyes go through five zang viscera during daytime, and enter five zang viscera during night. Nutrient qi and defensive qi accompanying with each other means sequential and nutrient qi and defensive qi fighting with each other means reverse.
