The anterior yin of women, along with conditions such as yin sores (ulcers of the vulva/vagina) and jun ting (vaginal polyps/prolapse), are all compiled in this section for easy reference and treatment consultation.

*Jingui Yaolue* states: "When stomach qi descends abnormally, causing yin blowing (flatulence from the vagina) with loud noise, it is because grain qi cannot ascend to the clear orifices, nor can it follow the meridians downward to exit through the posterior yin. The yin and yang qi are deviant and disordered, similar to the meaning of intestinal entanglement." In severe cases, there may be rustling sounds resembling flatulence from the anus. The appropriate treatment is Buzhong Yiqi Tang (Supplement the Middle and Boost Qi Decoction) added with Wuweizi (Schisandra Berry).

*Jianwen Suilu* records: "If a postpartum woman consumes green onions, accidental ingestion will inevitably lead to yin blowing."

Wang Kentang stated: "The external genitalia are the convergence point of the Foot-Jueyin Liver Meridian and the Ren Mai (Conception Vessel)." (*Zhunsheng*)

He further stated: "According to the theory of influencing factors (Yunqi), yin sores belong to cold patterns. The classic text says: 'With dampness of Taiyang, ulcers occur in the yin region, accompanied by difficulty in private functions; treat with bitter-hot herbs.' This refers to the use of bitter and hot natured medicines."

*Suwenn* states: "The meridians of Jueyin connect to the external genitalia and are tied to the Liver."

It also states: "The Luo (Connecting) vessels of the Du Mai (Governing Vessel) circulate along the external genitalia and converge between the perineum." As for the Foot-Taiyang Bladder Meridian, it externally corresponds to clear water, internally belongs to the Bladder, and regulates water passages; the Hand-Taiyang Small Intestine Meridian externally corresponds to Huai water, internally belongs to the Small Intestine, and water passages emerge from it. Thus, these involve the Hand and Foot Taiyang meridians. Since the Kidney governs water metabolism, this also involves the Foot-Shaoyin Kidney Meridian. When drink enters the Stomach, its essence floats up, is transported upward to the Spleen, the Spleen scatters the essence, which returns upward to the Lung; the Lung regulates water passages and transports them downward to the Bladder. Thus, this involves the Hand-Taiyin Lung Meridian. *Suwenn* further states that the anterior yin is where the Zongjin (Major Sinews) gather, and is the convergence of the Taiyang and Yangming meridians; thus, it also involves the Spleen and Kidney. When abscesses and sores arise in this area, one must carefully investigate the cause and determine responsibility. One should not focus solely on the Foot-Jueyin Liver Meridian, treating only by clearing Liver heat and draining dampness, to avoid errors.

*Lingnu* states: "Sinews gather at the external genitalia and their meridians connect to the root of the tongue. The Liver is the assembly of sinews, and it also relates to the Du Mai."

Zhang Zhongjing stated: "When the Shaoyin pulse is slippery and rapid, sores will appear in the yin region. If the yin region is eroded and ulcerated, wash it with Yelangya Tang (Wolf's Tooth Decoction). [Usage: Use two liang of Yelangya (Tetracentron sinense stem bark), boil in four sheng of water until reduced to half a sheng. Wrap cotton around a chopstick like a silkworm cocoon, dip in the decoction, and irrigate the yin region twice.]"

Qian Tianshi said: "Roughly, nine out of ten hidden diseases affect women. They may occur outside or inside the Ermen (anus). These can only be described generally, yet many feel ashamed and unwilling to speak fully. They can only be understood intuitively and contemplated silently. Generally, diseases of the Ermen present as either itching or pain. They should be treated with Mozhi Tang (Silent Treatment Decoction). This formula consists of herbs that soothe the Liver and remove dampness. Regardless of whether there is fire or no fire, wind or dampness, it achieves miraculous results. There is no need to ask specifically how it itches, swells, hurts, or ulcerates." (*Milu*)

Chen Shigong stated: "Women's yin sores are caused by emotional stagnation transforming into fire, damaging the Liver and Spleen, with damp-heat pouring downward. The manifestations vary, but all originate from evil fire transformation." (*Zhengzong*)

Xue Lizhai stated: "A toxic sore arising in the center of the hairline of the yin opening is called Yingai Du (Yin Cover Toxin), characterized by redness, swelling, and pain. This is formed by stagnant Liver fire. Treatment should involve clearing the Liver and nourishing blood, with external applications to dissipate swelling. If pus has formed, treat according to the methods for carbuncles and sores."

He further stated: "Swelling nodules on one side of the yin opening, or on both sides, shaped like a silkworm cocoon, are called Yin Jian (Yin Cocoon). Internal pus forms and eventually ruptures spontaneously. This condition results from Liver fire and damp-heat, or injury from new marriage, or infection from unclean intercourse."

He also stated: "Swelling, pain, and ulceration of the uterus within the yin opening are called Tingkong Du (Palace Hole Toxin). Severe cases stem from stagnant Liver fire; mild cases from sexual injury. For both, Hai Fu San (Sea Floating Powder) mixed with oil should be instilled. The patient should lie supine for a long time, then apply Yu Hong Gao (Jade Red Ointment) mixed with Hai Fu San, soaked into a cotton tampon, and inserted for effectiveness."
