Miscellaneous Formulas
Yan Shi Washing Method treats Huoluan (cholera-like syndrome) with muscle spasms.
Take one handful of Polygoni Multiflori Herba (Liao, 蓼), remove both ends, add 3 sheng of water, boil down to 2 sheng, let cool to warm temperature, and use for fumigation and washing.
Soaking Method treats Huoluan (cholera-like syndrome) with muscle spasms pulling into the abdomen.
Use abundant salt to make a decoction, pour into a trough, and soak the affected area warmly.

San Yin Vomiting Method treats Dry Huoluan (severe cholera without vomiting/diarrhea initially), Gu Du (poisoning), retained food not digesting, accumulation of cold causing abdominal distension and fullness, and Gui Qi (sudden mysterious illness). Use extremely salty salt water (3 sheng), drink 1 sheng hot, stimulate the throat to induce vomiting of retained food until empty. If no vomiting occurs, administer again; after vomiting, drink more, inducing vomiting three times in total, then stop. This method surpasses other treatments, but laypeople consider it rustic and crude, refusing to use it, preferring death by adherence to convention. For such syndromes, this method should be used first. Yuan Rong stated: After vomiting subsides, use Lizhong Decoction (Lizhong Tang, 理中汤) to regulate.

Moxibustion Method treats Huoluan (cholera-like syndrome) where the patient appears dead but warmth remains in the abdomen. Fill the umbilicus with salt and perform moxibustion for 2 × 7 zhuang (14 moxa cones).
