娄全善先生云∶痘腹痛多是热毒为患，当临症消息之。又云∶痘出腹痛，或身痛脉洪数者，用解毒凉药加芍药、甘
草。窃谓前症若痘未出而发热烦躁，或作渴饮冷，大便坚实，此热毒壅滞也，用疏利之药。若痘已出而不热躁，不饮
冷，大便不实，此元气虚弱也，用白术散之类补之。若嗳腐吞酸，大便秽臭，乳食停滞也，用保和丸消之。凡腹痛作渴
饮冷，手足并热者，属实热；作渴饮汤，手足并冷者，属虚寒。虚寒者，当温补脾胃；虚弱者，当调补脾胃。

Mr. Lou Quanshan stated: Abdominal pain caused by smallpox is mostly due to heat-toxin pathogenesis; one should carefully assess the symptoms clinically. He further stated: If abdominal pain occurs after the eruption of smallpox, accompanied by body pain and a flooding, rapid pulse, use cooling and detoxifying herbs with added Paeoniae Radix (Shaoyao) and Glycyrrhizae Radix et Rhizoma (Gancao).
I believe that in the aforementioned conditions, if fever and restlessness occur before the eruption of smallpox, or if there is thirst with a desire to drink cold water and hard, dry stools, this indicates stagnation of heat-toxin; one should use herbs that promote drainage and purgation. If the smallpox has erupted but there is no fever or restlessness, no desire for cold drinks, and loose stools, this indicates deficiency of primordial qi; one should use formulas such as Baizhu San (Atractylodes Macrocephala Powder) to tonify. If belching with a rotten smell, acid regurgitation, and foul-smelling stools occur, this indicates retention of milk and food; one should use Baohe Wan (Harmonize the Stomach Pill) to resolve stagnation. Whenever abdominal pain is accompanied by thirst with a desire for cold drinks and hot hands and feet, it belongs to excess-heat; when thirst is accompanied by a desire for warm drinks and cold hands and feet, it belongs to deficiency-cold. For deficiency-cold, one should warm and tonify the Spleen and Stomach; for qi deficiency, one should regulate and tonify the Spleen and Stomach.
A child who had a good appetite but was prone to thirst, suffering from abdominal pain and constipation, with red smallpox scars, was cured using Jiawei Siwu Tang (Modified Four Substances Decoction). Later, pain and anorexia recurred, indicating injury to the Spleen and Stomach; he recovered after taking Baizhu San (Atractylodes Macrocephala Powder).
A child whose smallpox was about to crust over presented with abdominal distension, fever, and facial redness, worsening in the afternoon. Palpation of the abdomen revealed no pain; I diagnosed Spleen deficiency and treated him with Wuwei Yigong San (Five-Ingredient Extraordinary Efficacy Powder), resulting in recovery.
A child with smallpox-induced abdominal pain, stool resembling diarrhea, and alternating chills and fever was diagnosed with Spleen qi deficiency; treatment with Baizhu San (Atractylodes Macrocephala Powder) led to recovery.
A child with smallpox presented with abdominal pain and thirst, normal diet, and bright, vibrant red smallpox lesions. This was diagnosed as excess-heat in the Stomach meridian. Initial treatment with Xiehuang San (Drain Yellow Powder) brought immediate relief after one dose, followed by recovery with Baizhu San (Atractylodes Macrocephala Powder). *(Note: Original text says "Baimu San", likely a typo for Baizhu San)*.
After a child's smallpox episode, abdominal pain and thirst with cold water intake and constipation occurred. Five fen of Qingliang Yin (Cooling Drink) powder provided immediate relief. Subsequently, abdominal pain, vomiting, diarrhea, and convulsions developed; treatment with Baizhu San (Atractylodes Macrocephala Powder) plus Uncaria rhynchophylla (Gouteng) resulted in cure.
A child with smallpox-induced abdominal pain, belching with a rotten smell, and acid regurgitation was diagnosed with food stagnation. Two doses of Baohe Wan (Harmonize the Stomach Pill) were administered first, followed by Wuwei Yigong San (Five-Ingredient Extraordinary Efficacy Powder) to stop the pain, and Tuoli San (Support the Interior Powder) to facilitate crusting.

**Qiwei Baizhu San (Seven-Ingredient Atractylodes Macrocephala Powder)**: Treats abdominal pain, harmonizes Stomach qi, and generates body fluids.
