攻。名系阴阳表里。或一物而生熟互异，更分暑湿风寒。辞简意周，几无余义。诚发前篇之
所未尽也。其可不熟读而详记之乎。
天有阴阳，风寒暑湿燥火。三阴三阳上奉上，温凉寒热四气是也。温热者，天之阳也。
寒凉者，天之阴也。此乃天之阴阳也。
地有阴阳，金木水火土，生长化收藏下应之。辛甘淡酸苦咸五味是也。辛甘淡者，地之
阳也，酸苦咸者，地之阴也。此乃地之阴阳也。
阴中有阳，阳中有阴。平旦至日中，天之阳也，阳中之阳也。日中至黄昏，天之阳，阳
中之阴也。合夜至鸡鸣，天之阴，阴中之阴也。鸡鸣至平旦，天之阴，阴中之阳也。
故人亦应之，人身之阴阳，外为阳，内为阴。背为阳，腹为阴。脏为阴，腑为阳。心肝
脾肺肾五脏为阴。胆胃大肠小肠膀胱三焦六腑为阳。所以知阳中之阴阴中之阳者，何也。如
冬病在阴，夏病在阳，春病在阳，秋病在阴。知其所在，则施针药也。
背为阳，阳中之阳，心也；背为阳，阳中之阴，肺也；腹为阴，阴中之阴，肾也；腹为
阴，阴中之阳，肝也；腹为阴，阴中之至阴，脾也。此系阴阳表里内外雌雄相输应也。

The above covers ninety medicinal substances in total, each assigned a short verse. Having clarified their ascending, descending, floating, and sinking properties, it further establishes the roles of Sovereign, Minister, Assistant, and Courier herbs. Some single herbs attack both internally and externally. Their names relate to Yin-Yang and Exterior-Interior. Some substances differ in effect depending on whether they are raw or processed, further distinguishing influences of Summer-heat, Dampness, Cold, and Wind. The language is concise yet comprehensive, leaving little unexpressed. This indeed elucidates what was not fully covered in the previous chapters. How could one fail to study them thoroughly and memorize them in detail?
Heaven possesses Yin and Yang, corresponding to Wind, Cold, Summer-heat, Dampness, Dryness, and Fire. The Three Yin and Three Yang correspond upwards to Heaven, manifested as Warm, Cool, Cold, and Hot Four Natures. Warm and Hot belong to Heaven's Yang. Cold and Cool belong to Heaven's Yin. This is the Yin-Yang of Heaven.
Earth possesses Yin and Yang, corresponding to Metal, Wood, Water, Fire, and Earth, with Growth, Transformation, Harvest, Storage, and Conservation responding downwards. Pungent, Sweet, Bland, Sour, Bitter, and Salty Five Flavors are manifestations of Earth. Pungent, Sweet, and Bland belong to Earth's Yang. Sour, Bitter, and Salty belong to Earth's Yin. This is the Yin-Yang of Earth.
Yin contains Yang, and Yang contains Yin. From dawn to noon, it is Heaven's Yang, specifically Yang within Yang. From noon to dusk, it is Heaven's Yang, specifically Yang within Yin. From nightfall to cockcrow, it is Heaven's Yin, specifically Yin within Yin. From cockcrow to dawn, it is Heaven's Yin, specifically Yin within Yang.
Thus, humans also correspond to these principles. In the human body, the exterior is Yang, the interior is Yin. The back is Yang, the abdomen is Yin. Zang organs are Yin, Fu organs are Yang. The five Zang organs—Heart, Liver, Spleen, Lung, Kidney—are Yin. The six Fu organs—Gallbladder, Stomach, Large Intestine, Small Intestine, Bladder, Sanjiao (Triple Burner)—are Yang. Why do we know that there is Yin within Yang and Yang within Yin? For instance, winter diseases reside in Yin, summer diseases in Yang, spring diseases in Yang, and autumn diseases in Yin. Knowing their locations allows for the application of acupuncture and herbal medicine.
The back is Yang; the Yang within Yang is the Heart. The back is Yang; the Yin within Yang is the Lung. The abdomen is Yin; the Yin within Yin is the Kidney. The abdomen is Yin; the Yang within Yin is the Liver. The abdomen is Yin; the Ultimate Yin within Yin is the Spleen. This reflects the mutual correspondence among Yin-Yang, Exterior-Interior, Inside-Outside, and Male-Female principles.
