Ben Shi Fang (Formulas from the Hand of a Master) Qu Wan: Treats wind-stroke or wind-dampness invading the zang-fu organs, resulting in slipping diarrhea.
Chuanxiong Rhizome (Chuanxiong), Prepared Aconite Root (Fuzi), Medicated Leaven (Shenqu), Atractylodis Macrocephalae Rhizoma (Baizhu) (equal parts).
Grind the above into a fine powder, use wheat paste to make pills the size of paulownia seeds. Take 30-50 pills each time, with warm rice water. This medicine also treats undigested food diarrhea (Sun-xie).
Note: This formula is derived from the treatment principles of the Taiyin syndrome.

Astringent Formulas (Note: Various formulas and discussions are found in the "Dysentery" category).

Ben Shi Fang Wen Pi Tang: Treats chronic cold lodged between the intestines and stomach, causing diarrhea and abdominal pain. One should first purge and remove the accumulation, then proceed with regulation and treatment; one must not fear deficiency and thereby nurture the disease.
Magnolia Bark (Houpo), Dried Ginger (Ganjiang), Licorice Root (Gancao), Cinnamon Twig (Guixin), Raw Aconite Root (Fuzi, raw, 2 liang each), Raw Rhubarb (Dahuang, raw, 4 qian, crushed, soaked in one bowl of decoction for half a day, squeezed to extract the juice, and added back with the dregs when boiling the decoction).
Finely chop the herbs, add two and a half sheng of water, boil down to eight ge, then add the Rhubarb juice, boil further down to six ge, strain, and take.
Note: Diarrhea and dysentery with abdominal pain present various syndromes. If there is accumulation, it is indeed appropriate to purge and remove it. But it is not limited to chronic cold alone. One must carefully differentiate the excess/deficiency and cold/heat, and regulate according to what is suitable.

Dong Yuan Sheng Yang Chu Shi Tang: For conditions where the pathogenic factor rises from below upwards, guide it out by lifting (Yin er jie zhi).
Cimicifugae Rhizoma (Shengma), Bupleuri Radix (Chaihu), Saposhnikoviae Radix (Fangfeng), Medicated Leaven (Shenqu), Alisma Rhizoma (Zexie), Polyporus (Zuling), Citrus Reticulata Pericarpium (Chenpi), Atractylodis Rhizoma (Cangzhu), Hordeum Vulgare (Damai), Wheat Flour (Mian), Roasted Licorice Root (Gancao, roasted, 3 qian each). If there is stomach cold with borborygmus, add Alpinia Oxyphylla Fruit (Yizhiren) and Pinellia Tuber (Banxia), half a qian each, decocted together with ginger and jujube. Do not use this modification unless there is borborygmus.
Take as one dose, decoct with water, drink hot after breakfast.

Sheng Yang Chu Shi Fangfeng Tang: If there is fecal impaction or tenesmus (feeling of incomplete evacuation), frequent trips to the toilet but inability to defecate, or presence of white pus or blood in stool, do not use purgatives/laxatives. Using purgatives will inevitably lead to severe illness and stagnation/blockage. By using this formula to raise the yang qi, the yin qi will naturally descend.
Atractylodis Rhizoma (Cangzhu, soaked in rice water, peeled, cleaned, 4 liang), Saposhnikoviae Radix (Fangfeng, 2 qian), Atractylodis Macrocephalae Rhizoma (Baizhu), Poria (Baifuling), White Peony Root (Baishao) (1 qian each).
Crush the herbs. Except for Cangzhu which is sliced separately, add one and a half bowls of water, boil down to two bowls. Add the other herbs and boil down to one large bowl. Drink hot before meals.
Note: When food enters the stomach, clear qi rises and is transported to the heart and lungs, then turbid qi descends. If the spleen and stomach are damaged, clear qi cannot rise but instead flows downward into the liver and kidneys, resulting in diarrhea and dysentery. The treatment method should be to tonify the middle qi and lift and raise it; one must not use draining and descending methods. This is Dong Yuan's theory that elucidates points not previously discussed by predecessors.
