It should be taken on the morning of the day when the paroxysm occurs.

Huangdan (Calomelas, roasted until the color changes)
Mix the above with high-quality Jian tea, combining two qianbi (a traditional unit of weight/volume). Administer by mixing with white boiled water; or mix with warm wine, without adding tea.

Xiongheidou (Forty-nine grains of male black soybeans, soaked in well water on the fifth day of the fifth lunar month [Duanwu Festival], skin removed the next day, dried, and ground into a paste) Zhenpi (Real Realgar/Orpiment, one qian, finely ground and mixed evenly into the bean paste)
Prepare pills at noon on the fifth day of the fifth lunar month, sized like mung beans. Dry them thoroughly, coat with Chen Sha (Cinnabar), and seal in an airtight container. On the day of the paroxysm, swallow one pill on an empty stomach with "Jinghua Shui" (water drawn from a well just as dawn breaks).
Avoid seeing chickens and dogs. If the patient is female, have a man close his eyes while administering the medicine into her mouth. Avoid hot food for one day after administration. Pregnant women must not take this. On the day of the paroxysm, tie one pill to the right arm with a silk strip. For children who cannot swallow, tie it to the left arm for boys and the right arm for girls.

Another prescription
Huangdan (Calomelas, quantity unspecified)
On the fifth day of the fifth lunar month, roast a single-clove garlic until cooked, grind it finely, and use it to bind the powder into pills sized like wu zi (seeds of Cercis chinensis). Take five pills each time. One hour before a meal prior to the expected onset, administer with decoction made from peach and willow branches.

Qingdai (Indigo Naturalis) Guixin (Cortex Cinnamomi) Pi (Realgar/Orpiment) Badou (Semen Crotonis) Liuhuang (Sulfur) (Equal parts)
Do not remove the shells or process these ingredients specially. Grind them into powder. Use "Zongjiao" (the corner of a sticky rice dumpling wrapped in reed leaves) from five different households on the fifth day of the fifth lunar month as a binder to form pills sized like jujube seeds. Wrap securely in cotton cloth. On the day of the paroxysm, insert into the ear: left ear for males, right ear for females. Avoid meat and fish.

Although classical texts mention "Seven Types of Hernia" (Qi Shan), specific names and manifestations for various hernias are rarely detailed, with only Cold Hernia (Han Shan) and Masses (Jia Qi) being mentioned. Only the *Suwen: Daqi Lun* lists five types of hernia based on the pulse conditions of the five zang organs: A large, rapid, and deep kidney pulse indicates Kidney Hernia; a large, rapid, and deep liver pulse indicates Liver Hernia; a slippery, rapid, and forceful heart pulse indicates Heart Hernia; a deep and forceful lung pulse indicates Lung Hernia; and a rapid yin pulse indicates Spleen Hernia. Here, "Three Yin" refers to the Taiyin Spleen pulse. Generally speaking, blood stagnation due to cold forms Jia Qi (masses), while cold aggregation forms Shan (hernia). However, the pulse characteristics of the five zang organs differ, so they must be distinguished carefully. The kidney pulse is naturally deep, and the heart pulse is naturally slippery; becoming rapid/tense upon cold invasion is logically consistent. However, the liver pulse is naturally wiry, and the lung pulse is naturally choppy; describing both as "deep" is not entirely accurate. Furthermore, the spleen pulse does not show its characteristic features, merely stating that a rapid pulse indicates hernia, which is a textual omission. Whenever "rapid" (Ji) is mentioned, it actually implies "tight" (Jin). A tight pulse indicates cold, which can be inferred analogously. Additionally, pathogenic winds entering the abdomen can cause hernia, as can exposure to summer heat and dampness. Therefore, the meaning of "rapid" should be adjusted according to the four seasonal climates: wind presents with floating and wiry pulses, summer heat with surging and rapid pulses, and dampness with slow and fine pulses. This is clearly consistent with medical theory. It must be understood that although hernias involve the qi of the zang organs, they are primarily caused by external factors.
