The average person takes Chinese medicine, no matter what kind of medicine, probably one packet of medicine a day, after decoction, divided into the morning and evening each time to take. This seems to have become a habit, and everyone takes their medicines this way. I don’t know that the way of taking Chinese medicine is very delicate, and it’s not so simple by any means. According to the difference between the ruler and the minister, the Chinese herbal formula will determine the yin and yang attributes of the whole formula. Yang medicines nourish Yang, Yin medicines nourish Yin. The four seasons of the day, like the four seasons of the year, have their own characteristics. In the Yellow Emperor’s Classic of Internal Medicine, “Suwen. Jin Gui true speech” recorded: “Ping Dan to the middle of the day, the day of the sun, the sun in the sun; the middle of the day to dusk, the day of the sun, the sun in the sun in the yin; together with the night to the rooster’s song, the day of the yin, yin in the yin; rooster’s song to the middle of the day, the day of the yin, yin in the yang, and so people should also.” The meaning is that the morning to noon, for the yang in the yang, that is, re-yang, noon to dusk, for the yang in the yin, that is, from the yang into the yin also; the day will be dark to the middle of the night, for the yin in the yin, the middle of the night to the morning, for the yin in the yang, this is the nature of the yin and yang changes in the daytime clock phenomenon. According to its theoretical reasoning, good complementary yang of the weak, should be served in the morning yang medicine, at this time the yang is in a state of growth, plus yang medicine, push the boat, the yang is more vigorous; good complementary yin of the weak, should be served in the evening after the yin medicine, at this time yin is in a state of growth, plus yin medicine, the Yin is more vigorous. Similarly, want to diarrhea heat of the real person, should be served in the afternoon yin medicine, this time the yang gas is in a state of recession, to clear the heat of the medicine, let nature take its course, the yang gas recede faster; want to warm the cold of the real person, should be served before dawn yang medicine, this time the yin gas is in a state of recession, to warm the medicine, let nature take its course, then the yin gas dissipate more quickly. The tediousness of the medication so, visible Chinese medicine of the vast and profound, classic things worth studying too much, can not get one and enough ah! This is my reading experience, for everyone to share.
