黄帝曰：妇人无须者，无血气乎？歧伯曰：冲脉任脉皆起于胞中，上循背里，为经络之海，其浮而外者，循腹右上行，会于咽喉，别而络唇口，血气盛则充肤热肉，血独盛者澹渗皮肤，生毫毛。今妇人之生有馀于气，不足于血以其数脱血也，冲任之脉，不荣口唇，故须不生焉。
黄帝曰：士人有伤于阴，阴气绝而不起，阴不用，然其须不去，其故何也？宦者独去何也？愿闻其故。歧伯曰：宦者去其宗筋，伤其冲脉，血写不复，皮肤内结，唇口不荣故须不生。
黄帝曰：其有天宦者，未尝被伤，不脱于血，然其须不生其故何也？歧伯曰：此天之所不足也，其任冲不盛、宗筋不成，有气无血，唇口不荣，故须不生。
黄帝曰：善乎哉！圣人之通万物也，若日月之光影，音声鼓响，闻其声而知其形，其非夫子，孰能明万物之精。是故圣人，视其颜色黄赤者，多热气，青白者少热气，黑色者多血少气，美眉者，太阳多血；通髯极须者，少阳多血，美须者阳明多血，此其时然也。
夫人之常数，太阳常多血少气，少阳常多气少血，阳明常多血多气，厥阴常多气少血，少阴常多血少气，太阴常多血少气，此天之常数也。

Huangdi said: 'Women have no beard — is this because they lack blood and qi?' Qibo said: 'The Penetrating Vessel (Chongmai) and the Conception Vessel (Renmai) both arise within the uterus, ascend along the interior of the back, and form the sea of the channels and network vessels. Their branch that floats to the exterior travels up along the abdomen, converges at the throat, and then divides to network around the lips and mouth. When blood and qi are abundant, they fill the skin and warm the flesh; when blood alone is abundant, it seeps out and moistens the skin, giving rise to fine hair. Now, in the constitution of women there is a surplus of qi but a deficiency of blood, because they repeatedly lose blood through menstruation; hence the vessels of the Penetrating and Conception channels cannot nourish the lips and mouth, and so no beard grows.'
Huangdi said: 'When a man is injured in his yin — when his yin qi is cut off so that he cannot become erect, and his yin organ is rendered useless — his beard nonetheless does not fall away. Why is this? And why is it that eunuchs alone lose their beard? I wish to hear the reason.' Qibo said: 'In the eunuch, the ancestral sinew, the genital organ, has been removed, injuring the Penetrating Vessel; the blood that is drained away cannot be restored, the skin binds up internally, and the lips and mouth are no longer nourished — hence no beard grows.'
Huangdi said: 'There are also natural eunuchs, who have never been injured and have never lost blood, and yet their beard does not grow. Why is this?' Qibo said: 'This is a congenital insufficiency bestowed by Heaven. In such persons the Conception and Penetrating vessels are not abundant, and the ancestral sinew fails to develop fully; they have qi but no blood, and so the lips and mouth are not nourished, and no beard grows.'
Huangdi said: 'Excellent indeed! The sage's comprehension of the myriad things is like the light and shadow cast by the sun and moon, like the resonance struck from a drum by sound — one hears the tone and knows the shape. Were it not for you, Master, who could clarify the essence of the myriad things?' Thus the sage, observing a person's complexion, knows that one who is yellow or red has abundant heat qi; one who is green-blue or white has scant heat qi; one who is dark has abundant blood but scant qi. One with fine eyebrows has abundant blood in the Taiyang; one with connecting whiskers and a full beard has abundant blood in the Shaoyang; and one with a fine beard has abundant blood in the Yangming — this is simply how it naturally is.
Now, the constant measure for human beings is this: the Taiyang habitually has abundant blood and scant qi; the Shaoyang habitually has abundant qi and scant blood; the Yangming habitually has abundant blood and abundant qi; the Jueyin habitually has abundant qi and scant blood; the Shaoyin habitually has abundant blood and scant qi; and the Taiyin habitually has abundant blood and scant qi. This is the constant measure bestowed by Heaven.
