Dry Huoluan (Jueyu) presents with severe colicky pain in the heart and abdomen, a desire to vomit but inability to do so, and a desire to defecate but inability to do so. It is commonly known as "Intestinal Cramping Sha" (Jiaochang Sha). If not treated urgently, it leads to death. The treatment method involves drinking salt water to induce vomiting; external treatment by needling the Weizhong (BL40) acupoint is also effective. Regarding this syndrome, Wang Yutai in *Zhengzhi Zhunsheng* (Standard of Diagnosis and Treatment) attributes it to extreme stagnation of Spleen Earth failing to vent, leading to internal disturbance by fire-heat and failure of Yin and Yang to interact. Wu Jutong in *Wenbing Tiaobian* (Systematic Differentiation of Warm Diseases) attributes it to latent Yin clashing with dampness, resulting in a syndrome characterized solely by Yin cold without Yang. The prescribed formula uses Sichuan Pepper (Shu Jiao), Aconite Root (Fuzi), and Dried Ginger (Ganjiang), among other herbs.

I personally believe that Dry Huoluan, like Wet Huoluan, can present as either Cold or Heat syndromes. Treatment must be based on careful pattern differentiation, and one should not exclusively advocate for hot-natured formulas. Although Mr. Wu’s book excellently elucidates methods for treating Warm Diseases with detailed and clear differentiation, establishing a unique school of thought, his argument on this specific point remains biased and may mislead future practitioners. I hereby correct this view.

(Bingzhang) Note: Dry Huoluan often complicates with food retention and phlegm, combined with invasion by warm-turbid pathogens. Inducing vomiting via probing opens the upper jiao; acupuncture unblocks the meridians; promoting urination and defecation clears blockage in the lower jiao. When the upper, lower, interior, and exterior are all unblocked, the disease resolves spontaneously. Yin-cold syndromes typically manifest as lingering, dull abdominal pain; sudden severe pain is rare. Clinical examination requires careful scrutiny.

Yadanzi (Brucea javanica Seed) treats Xixili (Dysentery with intermittent course). Cheng Xingxuan's *Wenyu Yi'an* highly praises its efficacy. The dosage is thirty seeds, shelled to extract the kernel, wrapped in Longan Aril (Longyan Rou), rolled into pills, and taken orally once or twice daily with rice gruel, or three to four times daily until recovery. This herb is extremely bitter and cold in nature. Its potency reaches the convoluted parts of the Large Intestine to search out and expel damp-heat. It is not recorded in the *Bencao* (Materia Medica) but appears in *Youyou Jicheng*, where it is called "Supreme Holy Pill," which is also known as Kushenzi (Bitter Seed). It is widely available in pharmacies. My hometown's renowned physician, Mr. Zhang Yunhuan (Li Ying), also transmitted this prescription. My mother, Lady Zhou, who enjoyed distributing prescriptions, used it to treat Xixili with consistent success. It also treats Changfeng Bianxue (Blood in stool due to intestinal wind). For heat-dysentery presenting with red color and chronic non-resolution, it is also applicable, except in cases of deficiency-cold dysentery, which is contraindicated.

(Bingzhang) Note: I have also successfully treated multiple cases of intestinal-heat hematochezia and chronic heat-dysentery using Kushenzi kernels. However, my dosage is fourteen kernels per administration, paired with seven pieces of Longan Aril, taken separately in packets. Recovery occurs after two doses.
