There is a condition caused by excessive sexual indulgence, leading to loose and open couli (skin pores and interstitial spaces), allowing cold pathogenic factors to enter directly into the Three Yin meridians due to deficiency. This is called Yin Syndrome (Yin Zheng), an acute onset disease characterized by the absence of initial heat symptoms. The term "direct entry into Yin meridians" refers to the invasion of the Heart, Liver, Spleen, Lung, and Kidney meridians by severe cold qi. The cold penetrates from the collaterals between muscles directly into the zang organs. Whether affecting the Heart, Liver, Spleen, Lung, or Kidney, the vital energy is damaged and fails to circulate freely, resulting in Yin Syndrome. At this stage, it is urgent to use hot-natured herbs to unblock the meridians according to their pathways, gradually warming the body so that the warm qi within the zang organs can reach the collaterals between the muscles. One should select formulas such as Lizhong Tang (Regulate the Middle Decoction), Sini Tang (Reverse the Extremities Decoction), and Zhenwu Tang (True Warrior Decoction) for treatment based on syndrome differentiation.

Another type of Yin Syndrome involves direct invasion of the Foot-Shaoyin Kidney Meridian, often occurring after sexual activity followed by exposure to cold, or due to yang deficiency from excessive desire, allowing cold to enter via the deficiency. Symptoms include colicky pain in the umbilical and abdominal regions, cyanosis of the hands and feet, cold limbs (Jue Ni), and a faint pulse nearly imperceptible. In this emergency, decoct Fuzi Lizhong Tang and administer it externally. Take a bundle of scallion whites, roughly the size of a tea cup, bind it tightly, cut a segment one finger-thick, place it on the navel, and apply heat using a hot iron. It is ideal if the heat penetrates into the abdomen, forcing the pathogen out.

Zhenwu Tang: Fuzi (Aconiti Lateralis Radix Praeparata) [Minister herb], Fuling (Poria) [Minister herb], Baishao (Paeoniae Radix Alba, stir-fried with wine) [Assistant herb], Baizhu (Atractylodis Macrocephalae Rhizoma) [Monarch herb], Shengjiang (Zingiberis Rhizoma Recens) [Envoy herb].
Sini Tang: Gancao (Glycyrrhizae Radix et Rhizoma Praeparata cum Melle) [Minister herb], Ganjiang (Zingiberis Rhizoma) [Assistant herb], Fuzi (Aconiti Lateralis Radix Praeparata) [Monarch herb].
For severe cases, heavy doses should be used.

There is also Daiyang Syndrome (Floating Yang Syndrome), characterized by pale red discoloration on both cheeks, which is migratory and unstable. Patients may exhibit restlessness, mania, and a desire to sit in mud or water; they feel thirsty and want to drink but cannot swallow; stool may be spontaneous diarrhea or constipation; urine is clear-white or pale yellow; the throat may or may not hurt; the pulse is deep, slow, faint, and thin. Although the skin surface feels hot, deep pressure reveals no heat, and in severe cases, the cold penetrates through the hand. This is Yin Excess repelling Yang (Yin Sheng Ge Yang). Another presentation includes facial redness, restlessness, ulcers and prickles covering the tongue, tongue retraction resembling a lychee pit, profuse phlegm-saliva, panting urgency, frequent urination, dry mouth with desire to drink, cracked and scorched lips, a sensation of fire/smoke attacking upward from the throat, and burning sensations in the soles of the feet. The pulse is surging, rapid, and chaotic without order, feeling strong upon deep pressure (though sometimes weak upon deep pressure); the body feels scorching to the touch. This is Kidney Deficiency causing Fire to fail to return to its source, as described in the *Suwen* as "pulse contrary to the disease." All these conditions are treated with Shiquan Dabu Tang (Complete Great Tonifying Decoction), taken with Bawei Wan (Eight-Ingredient Pill), or large doses of Bawei Yin (Eight-Ingredient Decoction) combined with Shengmai San (Generate the Pulse Powder). The dosage of Renshen (Ginseng Radix) and Shudihuang (Rehmanniae Radix Praeparata) can be up to 2–3 liang, and Fuzi (Aconiti Lateralis Radix Praeparata) up to 3–5 qian. If mistaken for Baihu Tang (White Tiger Decoction) syndrome, death will ensue immediately.

Shiquan Dabu Tang: Huangqi (Astragali Radix, honey-fried), Rougui (Cinnamomi Cortex), Sijunzi Tang (Four Gentlemen Decoction), Siwu Tang (Four Substances Decoction).
