The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Manifestations of All Diseases) states: "Chaitui" refers to unilateral swelling of the scrotum. In individuals with deficiency on one side, Qi deficiency leads to impaired circulation, causing Qi and blood to stagnate and swell on that side.

The *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold) records the Wudeng Wan (Five-Grade Pill) for treating pediatric unilateral scrotal enlargement, involving the testicles and scrotum:
Fermented Soybean Paste (Douchi), Peony Bark (Mudanpi), Saposhnikovia Root (Fangfeng), Cinnamon Twig Heart (Guixin), Phellodendron Bark (Huangbai) (each two liang).
These five ingredients are processed into pills the size of soybeans. For a three-year-old child, administer five pills per dose, three times daily. For younger children, reduce the dosage according to circumstances; the pill can be placed on the nipple for the infant to suckle.

The *Zhubing Yuanhou Lun* states: Gan Shi disease is mostly due to prolonged diarrhea leading to Spleen and Stomach weakness. Between the intestines and stomach, parasites move and invade the five zang organs, causing mental restlessness and oppression; if they ascend and erode, sores appear in the mouth, nose, and gums; if they descend and erode, the anus becomes injured and ulcerated, both being difficult to treat. It may also result from prolonged diarrhea, heat in the zang organs causing lethargy, or a preference for sweet and delicious foods, which generates steaming heat and agitates the blood, leading to this condition.
