导赤汤（见口部口糜）
The syndrome of Yin swelling (scrotal swelling) often occurs in children, primarily due to prolonged sitting in cold and damp environments causing the congealing of Cold Qi (Cold Energy), or due to anger and crying leading to Qi stagnation and closure. Treatment should be selected based on the differentiation of Cold, Heat, Deficiency, and Excess patterns.
[Note] This syndrome is known in ancient texts as Tuo Nang (Scrotal Gangrene/Necrosis). It is caused by prolonged sitting in damp places, where Cold pathogen congeals; occasionally, it arises from anger and crying causing Qi obstruction and accumulation in the lower body. In such cases, Tao Ren Wan (Peach Kernel Pill) is generally indicated. If Cold pathogen invades the Jueyin (Liver Meridian) and Shaoyin (Kidney Meridian), symptoms include scrotal swelling and pain, abdominal pain, cold sweating, and retraction of the testes into the abdomen, returning only after the pain subsides; this is called Nei Diao (Internal Retraction). Wumei San (Mume Powder) and Yunqi San (Harmonizing Qi Powder) are indicated. If the penis is completely retracted and invisible, or if the scrotum is swollen, large, bright, dry-free, and painless, it indicates Deficiency of Liver and Kidney Qi. Juhe Decoction (Citrus Seed Decoction) taken with Yunqi San is indicated. If both the scrotum and limbs are swollen, accompanied by difficulty in urination and defecation, it is due to Heat-Turbidity accumulating in the Bladder combined with Wind-Heat. Bai Qian Niu San (White Morning Glory Powder) is indicated. If the vulva of a female child is swollen, it is due to Heart Heat transmission. Dao Chi Tang (Directing Out the Red Decoction) is indicated, or Wuling San (Five-Ingredient Powder with Poria) decocted with Yi Yi Ren (Coix Seed) and Che Qian Zi (Plantago Seed) for administration. For external treatment, Li Xiao San (Instant Resolution Powder) can be applied externally with excellent effect.
