转筋之为病，其人臂脚直，脉上下行，微弦，转筋入腹者，鸡屎白散主之。
【注】
臂同背，古通用。臂脚直，谓足背强直不能屈伸，是转筋之证也。脉上下行，谓迢迢
长直，微弦不和，是转筋之脉也。中寒之人，外寒盛则手足拘急转筋，痛不能忍，甚
者入腹，则牵连少腹拘急而痛也。主之鸡屎白散，以治风寒痹气之在筋也。
鸡屎白
右一味为散，取方寸匕，以水六合和，温服。

阴狐疝气者，偏有大小，时时上下，蜘蛛散主之。
【注】
偏有大小，谓睾丸左右有大小也。时时上下，谓睾丸入腹，时出时入也。疝，厥阴之
病也，以与狐情状相类，故名之也。主之蜘蛛散，入肝以治少腹拘急而痛也。
【集注】
赵良曰：睾丸上下，有若狐之出入无时也，故曰狐疝。
李□曰：偏有大小，以睾丸言。时时上下，以睾丸入小腹出囊中言。
尤怡曰：阴狐疝气者，寒湿袭阴而睾丸受病，或左或右，大小不同；或上或下，出没
无时，故名狐疝。
The Master said: In cases of Diejue (falling and stiffening disease), the patient can only move forward but not backward. The acupuncture point is located in the popliteal fossa (Weizhong, BL-40), with a needling depth of two cun. This indicates an injury to the Taiyang meridian (the Bladder channel).
[Commentary]
Both the symptoms and the acupuncture method are not detailed; there must be missing text, so no explanation is provided.
When a patient frequently experiences swelling and tremors in the fingers and arms, and if this person also exhibits body convulsions or stiffness, Lili Gancao Tang (Celandine and Licorice Decoction) should be administered.
[Commentary]
The symptoms are not detailed, and the formula is missing, so no explanation is provided.
Regarding the disease of Zhuanjin (muscle cramp/twisting spasm), the patient's arms and dorsum of the feet are straight and rigid. The pulse runs long and straight from top to bottom with a slight wiry quality. If the cramps extend into the abdomen, Jishi Bai San (Chicken Dropping White Powder) should be administered.
[Annotation]
"Bi" (arm) is interchangeable with "Bei" (back) in ancient texts. "Bi jiao zhi" refers to the rigidity of the dorsum of the foot, preventing flexion and extension, which characterizes the symptom of Zhuanjin. "Mai shang xia xing" describes a pulse that is long, straight, slightly wiry, and unharmonious, representing the pulse of Zhuanjin. Individuals with internal cold, when subjected to excessive external cold, experience contraction and cramping of the hands and feet, with unbearable pain. In severe cases, it extends to the abdomen, causing tension and pain in the lower abdomen. Jishi Bai San is prescribed to treat wind-cold bi syndrome affecting the sinews.
Jishi Bai (White excrement of Gallus gallus domesticus)
Process the single ingredient into a powder. Take one fangcun bi (a square-inch measure) and mix with six he of water. Administer warm.
Yinhu Shanqi (Yin Fox Hernia Qi) presents as asymmetry in size, with intermittent movement up and down. Zhizhu San (Spider Powder) should be administered.
[Annotation]
"Pian you da xiao" refers to the difference in size between the left and right testicles. "Shi shi shang xia" refers to the testicles retracting into the abdomen and protruding out intermittently. Shan (hernia) is a disease of the Jueyin liver channel. It is named "Fox Hernia" because its presentation resembles the behavior of a fox. Zhizhu San is prescribed to enter the Liver channel to treat tension and pain in the lower abdomen.
[Collected Annotations]
Zhao Liang stated: The testicles moving up and down resemble the unpredictable entry and exit of a fox, hence the name Fox Hernia.
Li [Name Missing] stated: "Asymmetry in size" refers to the testicles. "Intermittent movement up and down" refers to the testicles entering the lower abdomen and emerging from the scrotum.
You Yi stated: Yinhu Shanqi results from cold-dampness invading the yin region, affecting the testicles. They may differ in size on the left or right, and move up or down unpredictably, hence the name Fox Hernia.
