右一味末，以白粉少许，和合相得，如枣大，绵裹内之，自然温。

少阴脉滑而数者，阴中即生疮，阴中蚀疮，烂者，狼牙汤洗之。
【注】
阴中，即前阴也。生疮蚀烂，乃湿热不洁而生□也。用狼牙汤洗之，以除湿热杀□也
。狼牙非狼之牙，乃狼牙草也，如不得，以狼毒代之亦可。其疮深，洗不可及，则用
后法也。
【集注】
李□曰：少阴属肾，阴中，肾之窾也。『内经』曰：滑者阴气有余。又云：数则为热
。故阴中生疮蚀烂，皆湿热所致，狼牙味苦性寒，寒能胜热，苦能杀虫，故主洗之。
狼牙四两
右一味，以水四升，煮取半升，以绵缠□如茧，浸沥汤阴中，日四遍。

胃气下泄，阴吹而正喧，此谷气之实也，膏发煎导之。
【按】
「膏发煎导之」之五字，当是衍文。此谷气之实也之下，当有「长服诃梨勒丸」之六
字。后阴下气，谓之气利，用诃梨勒散；前阴下气，谓之阴吹，用诃梨勒丸，文义始
属，药病亦对。盖诃梨勒丸，以诃梨勒固下气之虚，以厚朴、陈皮平谷气之实，亦相
允合。方错简在『杂疗篇』内，下小儿疳虫蚀齿一方，杀虫解毒，或另有小儿门，或
列在杂方内，今于妇人杂病之末，亦错简也。
【注】
肾虚不固，则气下泄，阴吹而正喧，谓前阴出气有声也，此谷气之实，谓胃气实而肾
气虚也。以诃黎勒丸，固下气而泻谷气也。
蛇床子散方：
取蛇床子一味药，研成细末，加入少许白粉（古代用于化妆或治疗的铅粉/米粉），调和均匀，制成如枣核大小的药丸，用丝绵包裹后纳入阴道内，可使局部自然产生温热感。
狼牙汤方：
少阴经脉脉象滑利而数急的，外阴部就会生疮，外阴部腐蚀溃烂的，用狼牙汤清洗。
【注】
“阴中”，即指前阴（外生殖器）。生疮且腐蚀溃烂，是由于湿热和不洁净导致的。使用狼牙汤清洗，是为了清除湿热并杀灭虫邪。狼牙并非狼的牙齿，而是狼牙草。如果得不到狼牙草，用狼毒代替也可以。如果疮口较深，清洗无法触及，则采用后面的方法。
【集注】
李梴说：少阴经属于肾，阴中是肾气汇聚的空窍之处。《内经》说：脉滑表示阴气有余。又说：脉数则表示有热。所以阴中生疮、腐蚀溃烂，都是湿热所致。狼牙味苦性寒，寒能胜热，苦能杀虫，所以主治清洗。
狼牙四两
取狼牙一味药，用水四升，煮至剩余半升，用丝绵缠绕药物如蚕茧状，蘸取药汁沥入阴道内，每天四次。

胃气向下泄漏，前阴排气且声音喧闹，这是谷气（饮食积滞）实证的表现，应用膏发煎引导治疗。
【按语】
“膏发煎导之”这五个字，应当是衍文（多余的文字）。在“此谷气之实也”之下，应当有“长服诃梨勒丸”这六个字。后阴排气，称为气利，使用诃梨勒散；前阴排气，称为阴吹，使用诃梨勒丸，这样文义才连贯，药证也相对应。因为诃梨勒丸，用诃梨勒来固摄下焦之气虚，用厚朴、陈皮来平抑谷气之实，也是相符合的。该方错误地简编在《杂疗篇》内，下面还有小儿疳虫蚀齿一方，用于杀虫解毒，或者另有小儿门，或者列在杂方内，现在也在妇人杂病的末尾出现错简。
【注】
肾虚不能固摄，则气向下泄漏，前阴排气且声音喧闹，是指前阴出气有声。这里的“谷气之实”，是指胃气实而肾气虚。使用诃黎勒丸，以固摄下气并泻除谷气。
Decoction of Cnidii Fructus (Shechuangzi San):
Take one ingredient, Cnidii Fructus (Cnidium monnieri fruit), grind it into fine powder. Mix with a small amount of Bai Fen (White Powder, historically lead carbonate or rice flour used for cosmetic or therapeutic purposes) until well combined. Form into pills the size of a jujube pit. Wrap in silk cotton and insert vaginally; this will naturally produce a warm sensation.

When the Shaoyin pulse is slippery and rapid, sores will arise in the yin region. If there are erosive sores in the yin region that are ulcerated, wash them with Langya Tang (Wolf's Tooth Decoction).
[Annotation]
"Yin zhong" refers to the anterior yin (external genitalia). Sores arising and becoming erosive/ulcerated are caused by damp-heat and uncleanliness. Washing with Langya Tang serves to eliminate damp-heat and kill parasites. "Langya" does not refer to wolf teeth, but to Langya Cao (Wolf's Tooth Herb, likely Sarcandra glabra or similar). If unavailable, Radix Saposhnikoviae (Fangfeng) or potentially Datura metel root (Langdu, though toxic, was historically substituted in specific contexts, here noted as an alternative) may be used. If the sores are deep and washing cannot reach them, use the subsequent method.
[Collected Annotations]
Li Chen stated: The Shaoyin channel belongs to the Kidney. The yin region is the aperture of the Kidney. The *Neijing* states: "Slippery indicates excess Yin qi." It also says: "Rapid indicates heat." Therefore, sores arising in the yin region and becoming erosive/ulcerated are all caused by damp-heat. Langya has a bitter taste and cold nature; cold overcomes heat, and bitterness kills parasites. Thus, it is indicated for washing.
Langya (Wolf's Tooth Herb) 4 liang
Take one ingredient, Langya. Boil in 4 sheng of water until reduced to half a sheng. Wrap the herb in silk cotton like a silkworm cocoon, dip it in the decoction, and drip the liquid into the vagina. Do this four times daily.

Stomach qi leaks downward, causing flatulence from the anterior yin with audible noise. This is due to excess Gu Qi (food stagnation/grain qi). Apply Gaofa Jian (Fat and Hair Decoction) to guide it out.
[Commentary]
The five characters "Gaofa Jian dao zhi" (Apply Gaofa Jian to guide it out) should be considered interpolations (erroneous additions). Below "This is excess Gu Qi," the six characters "Chang fu Helile Wan" (Long-term administration of Terminalia Chebula Pills) should exist. Flatulence from the posterior yin is called Qi Li (Qi diarrhea/dysentery), treated with Helile San (Terminalia Chebula Powder); flatulence from the anterior yin is called Yin Chui (yin blowing/vaginal flatus), treated with Helile Wan (Terminalia Chebula Pills). Only then do the text meaning and the correspondence between medicine and disease align. Helile Wan uses Helile (Terminalia chebula) to secure deficient lower qi, and Houpo (Magnolia Bark) and Chenpi (Aged Tangerine Peel) to calm excess Gu Qi, which is consistent. The formula was erroneously placed in the *Miscellaneous Treatments Chapter*. Below it is another formula for pediatric gan-chong erosion of teeth, used to kill parasites and detoxify. This might belong in a separate pediatric section or miscellaneous formulas section. Its presence at the end of the Women's Miscellaneous Diseases chapter is also a textual error.
[Annotation]
Kidney deficiency failing to secure leads to qi leaking downward, causing audible flatulence from the anterior yin (Yin Chui). "Excess Gu Qi" here refers to Stomach excess combined with Kidney deficiency. Helile Wan is used to secure the descending qi and drain the excess Gu Qi.
