Weak pulse, deficient constitution, and excessive mental and physical labor. In previous years, after childbirth, a mass formed in the lower abdomen, causing intermittent pain. Recently, the pain has intensified in the morning, occurring daily.

The *Classic of Internal Medicine* states: "The Ren Mai (Conception Vessel) originates below Zhongji (CV3), running along the interior of the abdomen. When the Ren Mai is diseased, there is a sensation of internal knotting; men suffer from seven types of hernia, while women suffer from Jia Ju (masses that gather and disperse)." Further examining ancient discussions on Ji Ju (accumulations and masses), they are divided into two categories: Pin and Jia. "Pin" refers to tangible evidence; there is a palpable mass, indicating the disease is in the Blood aspect. "Jia" means false or temporary; it appears有形 (form) when gathered and leaves no trace when dispersed, indicating the disease is in the Qi aspect. This is largely due to postpartum conditions where cold invasion or Qi stagnation causes blood circulating along the meridians to coagulate and form shapes. These become firmly adhered and difficult to dissolve once enlarged. It requires the body's Yuan Qi (Original Qi) to be robust before gradual resolution can occur. If one pursues aggressive attack methods hastily, not only will the accumulation fail to dissipate, but the healthy Qi will also be damaged. The *Inner Canon* warns against attacking large accumulations and masses indiscriminately, which clearly illustrates this principle. Currently, the pain is severe and surging; rich, cloying tonics seem inappropriate. Considering that chronic pain often resides in the collaterals, and the Chong Mai (Penetrating Vessel) is the Sea of Blood, we first propose a decoction to harmonize the Chong and Ren vessels, ensuring smooth flow through the collaterals and free movement of Qi mechanisms. Once the pain subsides slightly, we will discuss pill preparations to eradicate the root cause.

An Bo’s Note: For the decoction, it is proposed to use the method of Tong Yu Jian (Unblocking Stasis Decoction) to make pills, combined with Hui Sheng Dan (Revive Life Pill) for simultaneous purgative and tonic effects.

After ten days of Yi Zheng (epidemic febrile disease), there is deficiency of healthy Qi mixed with pathogenic factors. Symptoms include listlessness, deafness, and persistent fever. The pulse is deep, fine, and powerless. Based on the pulse, the treatment should theoretically involve strengthening the Middle Jiao and warming to support expulsion. However, reviewing the prescription, three doses of Li Yin Jian (Regulating Yin Decoction) were taken, yet the condition worsened daily, suggesting the previous method is difficult to continue. Yang syndrome presenting with Yin pulse is generally inadvisable. Medical texts note that in epidemic diseases, pathogens may lie hidden internally, resulting in a deep and fine pulse, unlike Shang Han (Cold Damage) where pathogens come from outside, typically presenting with a floating and large pulse. This statement is worth considering. We imitate Zhao’s method of Liu Wei Tang (Six-Ingredient Decoction) adding Chai Hu (Bupleurum). On follow-up, the pulse remains deficient and fine; spirit and form are exhausted; lips and teeth are dry; tongue coating is yellow, dry, and turning black. Pathogenic heat is the greatest thief of True Yin. In elderly patients with inherent Kidney Yin deficiency, severe heat further consumes fluids. As stated in *Ji Ren Bian*, managing infectious syndromes always prioritizes preserving fluids. This is because the Dry Earth of the Yangming channel relies entirely on the Kidney Water of Shaoyin for nourishment. Like a dry field next to a wellspring, irrigation is possible if the spring exists; but if the spring dries up, the dry earth steams, and seedlings wither. Therefore, we adopt Gan Lu Yin (Sweet Dew Decoction).
