声音者，手太阴之所司也。肺藏气，而气之激宕则为声，故肺病而声为之不调，气病而声为之不畅。

须发者，手足六阳之所荣也。六经血气盛，则美而长。血气衰，则恶而短。夫须发者，营血之所滋生

声音的产生，由手太阴肺经所主管。肺脏贮藏气，而气的激荡变化则形成声音，因此肺发生病变时声音就会不调和，气发生病变时声音就会不畅通。
导致气发生病变的原因，是由于脾土（己土）湿气过重，土湿则声音喑哑。至于嘴唇缺损、牙齿脱落而导致言语不清的，是气外泄的表现。鼻涕流淌、鼻渊（鼻窦炎类疾病）且声音不明亮的，是气寒的表现。然而声音虽然出于气，但气的作用受神志支配，这就像门户的开合、机关的启闭一样，是由气来推动的。而之所以能掌管这些开合启闭，使声音快慢适中、高低适宜，则是神志在主宰。所以久咳导致音哑的，病位在声气；中风导致不能说话的，病位在神明。声气有病则能说话但不能响亮，神明有病则声音响亮但不能说话。声气源于肺，神明藏于心，声音由气动发，而言语由神志引发。那么调理声音的方法，就是补益清阳之气而驱除浊阴之气，这是一定的道理。如果湿气旺盛、气机郁滞导致声音不亮的，用茯苓橘皮杏仁汤主治。如果出现失声喑哑的，用百合桔梗鸡子汤主治。

胡须和头发，是手足六条阳经气血所滋养荣润的部位。六经的气血旺盛，胡须头发就美观且长。气血衰弱，胡须头发就枯黄短少。胡须头发，是由营血滋生，并由卫气发育而成的。血根在上部，但在下部旺盛；气根在下部，但在上部旺盛；胡须头发在上部旺盛而下部衰弱的，是因为手足六条阳经的经气在上部旺盛的缘故。大概胡须头发的生长，血用来滋润它，以滋养其根本；气用来温煦它，以荣润其枝叶。胡须脱落、头发焦枯的，是血衰而气败，应当在营气和卫气两方面同时培补根本与枝叶，就能痊愈。如果出现胡须脱落、头发焦枯、干枯无光泽的，用桂枝柏叶汤主治。

The production of voice is governed by the Hand-Taiyin Lung Meridian (Shǒu Tàiyīn Fèi Jīng). The Lungs store Qi, and the agitation and fluctuation of Qi generate sound. Therefore, when the Lungs are diseased, the voice becomes discordant; when Qi is diseased, the voice becomes obstructed.
The reason for Qi pathology lies in the dampness of the Earth element (Jǐ Tǔ, referring to Spleen/Stomach). When Earth is damp, the voice becomes hoarse or lost. As for unclear speech due to missing lips or fallen teeth, this is a manifestation of Qi leakage. For dripping nasal mucus, Nasal Sinusitis (Bí Yuān), and dull voice, this is a manifestation of Qi cold. However, although sound originates from Qi, Qi is directed by Shen (Spirit/Mind). Just as the opening and closing of doors or the activation of mechanisms, it is Qi that drives them. Yet, what governs these openings and closings, ensuring appropriate speed and pitch, is the direction of Shen. Thus, hoarseness due to chronic cough indicates pathology in Sheng-Qi (Voice-Qi); aphasia due to Stroke (Zhòng Fēng) indicates pathology in Shen-Ming (Spirit-Consciousness). When Sheng-Qi is diseased, one can speak but not loudly; when Shen-Ming is diseased, one can produce loud sounds but cannot articulate speech. Sheng-Qi originates from the Lungs, while Shen-Ming resides in the Heart. Sound is activated by Qi, and speech is initiated by Shen. Therefore, the method to regulate voice is to tonify Clear Yang and expel Turbid Yin, which is a fixed principle. If dampness is abundant and Qi is stagnant causing dull voice, Fu Ling Ju Pi Xing Ren Tang (Poria, Tangerine Peel, and Apricot Seed Decoction) is the primary treatment. If there is loss of voice or aphonia, Bai He Jie Geng Ji Zi Tang (Lily Bulb, Platycodon, and Egg White Decoction) is the primary treatment.

Beard and hair are nourished and flourished by the Qi and Blood of the six Yang meridians of the hands and feet. When the Qi and Blood of the six meridians are abundant, beard and hair are beautiful and long. When Qi and Blood decline, beard and hair become coarse and short. Beard and hair are generated by Ying-Blood (Nutritive Blood) and developed by Wei-Qi (Defensive Qi). Blood roots in the upper part but thrives in the lower part; Qi roots in the lower part but thrives in the upper part. The reason why beard and hair thrive in the upper part but decline in the lower part is that the meridian Qi of the six Yang meridians of the hands and feet is abundant in the upper part. Generally, the growth of beard and hair relies on Blood to moisten them, thereby nourishing their roots; and on Qi to warm them, thereby flourishing their branches and leaves. When beard falls out and hair becomes scorched, it indicates Blood deficiency and Qi failure. One should simultaneously tonify both the root (Ying) and the branch (Wei) to achieve recovery. If beard falls out, hair becomes scorched, dry, and lacks luster, Gui Zhi Bo Ye Tang (Cinnamon Twig and Biota Leaf Decoction) is the primary treatment.
Gui Zhi Bo Ye Tang (Cinnamon Twig and Biota Leaf Decoction)

Decoct in water until more than half a cup remains, take warm. If hair turns yellow, dry, and grays prematurely, add Sang Shen (Mori Fructus) and Hei Dou (Sojae Glycines Semen Nigrum). If Yang is deficient and Earth is damp, add Gan Jiang (Zingiberis Rhizoma) and Fu Ling (Poria). If Lung Qi is insufficient, heavily use Huang Qi (Astragali Radix), because the Lungs govern the skin and hair.
