内有五脏，心肝脾肺肾也。五脏不可望，惟望五脏之苗与窍。
舌乃心之苗。红紫心热也，肿黑心火极也，淡白虚也。
鼻准与牙床乃脾之窍。鼻红燥脾热也，惨黄脾败也。牙床红肿热也，破烂胃火也。
唇乃脾之窍，红紫热也，淡白虚也，黑者脾将绝也，口右扯肝风也，左扯脾之痰也。
鼻孔肺之窍，干燥热也，流清涕寒也。
耳与齿乃肾之窍。耳鸣气不和也，耳流脓肾热也，齿如黄豆，肾气绝也。
目乃肝之窍。勇视而睛转者风了，直视而睛不转者肝气将绝也。
以目分言之，又属五脏之窍。黑珠属肝，纯见黄色凶证也。白珠属肺，色青肝风伤肺也
，淡黄色脾有积滞也，老黄色乃肺受湿也。瞳仁属肾，无光彩又兼发黄，肾气虚也。目外角
属大肠，破烂肺有风也。目内角属小肠，破烂心有热也。上胞属脾，肿则脾伤也。下胞属胃
，青色胃有风也。睡而露睛者，脾胃虚极也。
小便短黄涩痛心热也，清长而利心虚也。
唇红而吐胃热也，唇惨白而吐胃虚也，唇色平常而吐作伤胃论。
大肠闭结，肺有火也，肺无热而便秘血枯也，不可攻下。脱肛肺虚也。
口苦胆火也，闻声作惊肝虚也。
又面有五色。面红病在心有热，面青病在肝多腹痛，面黄病在脾伤，面白病在肺中寒，
面黑病在肾，黑而无润色，肾气败也。望其色若异于平日，而苗窍之色与面色相符，则脏腑
虚实，无有不验者矣。
Where green veins appear straight above the Shan Gen (root of the nose), it indicates Liver Heat. Use Chai Hu (Bupleuri Radix) and Ban Xia (Pinelliae Rhizoma) each 3 fen, Bai Shao (Paeoniae Radix Alba) and Fu Ling (Poria) each 1 qian, Dang Gui (Angelicae Sinensis Radix) and Bai Zhu (Atractylodis Macrocephalae Rhizoma) each 5 fen, Shan Zha Rou (Crataegi Fructus flesh) 2 grains, Gan Cao (Glycyrrhizae Radix et Rhizoma) 1 fen. Decoct in water and take orally.
Where green veins appear horizontally above the Shan Gen, it is also Liver Heat. However, straight appearance indicates Wind pathogen moving upward, while horizontal appearance indicates Wind pathogen moving downward. Use the same prescription as above, adding Chai Hu (Bupleuri Radix) 2 fen, Mai Ya (Hordei Fructus Germinatus) 1 qian, and Gan Jiang (Zingiberis Rhizoma) 1 fen.
Where red veins appear straight, it indicates Heart Heat. Use the same prescription as above, adding Huang Lian (Coptidis Rhizoma) 1 fen, Mai Dong (Ophiopogonis Radix) 5 fen, Sang Bai Pi (Mori Cortex) 3 fen, and Tian Hua Fen (Trichosanthis Radix) 2 fen. Remove Ban Xia (Pinelliae Rhizoma) and do not use it.
Where red veins appear obliquely, it is also Heart Heat. Use the same prescription as above, adding Huang Lian (Coptidis Rhizoma) 2 fen. Remove Ban Xia (Pinelliae Rhizoma) and do not use it. This is because heat is extreme in the Bao Zhong (pericardium/heart region). Alternatively, add Sang Bai Pi (Mori Cortex) and Tian Hua Fen (Trichosanthis Radix).
If yellow veins appear at the Shan Gen or the skin color is yellow, regardless of whether the veins are horizontal or straight, it is always a Spleen-Stomach disorder. Symptoms may include watery diarrhea, vomiting, loose stools, abdominal pain, or loss of appetite. A single formula is prescribed here that can be taken for all such cases with miraculous effect. Use Bai Zhu (Atractylodis Macrocephalae Rhizoma) and Fu Ling (Poria) each 5 fen, Chen Pi (Citri Reticulatae Pericarpium), Dang Shen (Codonopsis Radix), and Mai Ya (Hordei Fructus Germinatus) each 2 fen, Shen Qu (Massa Medicata Fermentata) and Gan Cao (Glycyrrhizae Radix et Rhizoma) each 1 fen. Decoct in one zhong of water until half a jiu zhan remains. Divide into two doses. If there is phlegm, add Ban Xia (Pinelliae Rhizoma) 1 fen, or Bai Jie Zi (Sinapis Semen) 3 fen, or Hua Fen (Trichosanthis Radix) 3 fen; if there is heat with thirst, add Mai Dong (Ophiopogonis Radix) 3 fen and Huang Qin (Scutellariae Radix) 1 fen; if there is cold, add Gan Jiang (Zingiberis Rhizoma) 1 fen. For vomiting, add Bai Dou Kou (Amomi Fructus Rotundus) 1 grain; for diarrhea, add Zhu Ling (Polyporus) 5 fen. If abdominal pain occurs where the child holds their abdomen, and cries out in pain upon pressure, it is Food Stagnation; add Da Huang (Rhei Radix et Rhizoma) 3 fen and Zhi Shi (Aurantii Fructus Immaturus) 1 fen. If pressing causes no pain and no crying, it is Cold; add Gan Jiang (Zingiberis Rhizoma) 3 fen more. If the body has fever, this formula must not be used.
The interior contains the Five Zang Organs: Heart, Liver, Spleen, Lung, and Kidney. The Zang organs themselves cannot be observed directly by inspection; only their external manifestations (Miao) and orifices (Qiao) can be inspected.
The tongue is the Miao (external manifestation) of the Heart. Red and purple indicate Heart Heat; swollen and black indicate extreme Heart Fire; pale and white indicate Deficiency.
The tip of the nose and the gums are the Qiao (orifices) of the Spleen. Red and dry nose indicates Spleen Heat; sallow yellow complexion indicates Spleen failure. Red and swollen gums indicate Heat; ulcerated gums indicate Stomach Fire.
The lips are the Qiao (orifices) of the Spleen. Red and purple indicate Heat; pale and white indicate Deficiency; black indicates impending Spleen collapse. Deviation of the mouth to the right indicates Liver Wind; deviation to the left indicates Spleen Phlegm.
The nostrils are the Qiao (orifices) of the Lung. Dryness indicates Heat; clear nasal discharge indicates Cold.
The ears and teeth are the Qiao (orifices) of the Kidney. Tinnitus indicates Qi disharmony; purulent ear discharge indicates Kidney Heat; teeth loosening like soybeans indicates exhaustion of Kidney Qi.
The eyes are the Qiao (orifices) of the Liver. Vigorous gaze with rotating eyeballs indicates Wind has resolved; fixed gaze with non-rotating eyeballs indicates impending exhaustion of Liver Qi.
Speaking specifically about the eyes, they also belong to the orifices of the Five Zang Organs. The black part (iris/pupil area) belongs to the Liver; pure yellow is an ominous sign. The white part (sclera) belongs to the Lung; blue-green color indicates Liver Wind injuring the Lung; pale yellow indicates Spleen stagnation; old yellow indicates Lung dampness. The pupil belongs to the Kidney; lackluster and yellowish indicates Kidney Qi Deficiency. The outer canthus belongs to the Large Intestine; ulceration indicates Lung Wind. The inner canthus belongs to the Small Intestine; ulceration indicates Heart Heat. The upper eyelid belongs to the Spleen; swelling indicates Spleen injury. The lower eyelid belongs to the Stomach; bluish color indicates Stomach Wind. Sleeping with eyes partially open indicates extreme Spleen-Stomach Deficiency.
Short, yellow, and painful urination indicates Heart Heat; clear, long, and free urination indicates Heart Deficiency.
Red lips with vomiting indicate Stomach Heat; sallow white lips with vomiting indicate Stomach Deficiency; normal lip color with vomiting is treated as Stomach Injury.
Large intestine constipation indicates Lung Fire; if the Lung has no heat but constipation exists due to blood dryness, purgatives must not be used. Rectal prolapse indicates Lung Deficiency.
Bitter taste in the mouth indicates Gallbladder Fire; startle response to sound indicates Liver Deficiency.
Furthermore, the face presents five colors. Red face indicates disease in the Heart with Heat; green face indicates disease in the Liver with frequent abdominal pain; yellow face indicates Spleen injury; white face indicates Cold in the Lung; black face indicates disease in the Kidney. Black without luster indicates Kidney Qi failure. If the facial color differs from usual, and the colors of the external manifestations and orifices match the facial color, then the deficiency or excess of the Zang-Fu organs will be accurately diagnosed.
