Bowel obstruction is caused by disharmony among the Sanjiao (Triple Burner) and the Zang-Fu organs, with an imbalance of cold and heat. Heat qi pervades the intestines and stomach, exhausting body fluids and causing dryness, thereby leading to the stagnation and accumulation of fecal matter, resulting in blockage and lack of unobstructed passage.
For treating bowel obstruction due to heat oppression in the Lower Jiao, use the Dahuang San (Rhubarb Powder):
Radix et Rhizoma Rhei (Dahuang, 1 liang, crushed and lightly stir-fried), Arecae Semen (Binglang, 1 liang), Radix Aucklandiae (Muxiang, 0.5 liang), Natrii Sulfas (Chuan Mangxiao, 1 liang), Fructus Aurantii (Zhike, 1 liang, stir-fried with bran until slightly yellow, pith removed), Cortex Phellodendri (Ziqin, 0.5 liang).
Crush and sieve the above ingredients into a powder. Take 4 qian per dose. Add 1 zhong zhan of water, 0.5 fen of fresh ginger, and 7 cun of scallion white. Decoct until reduced to 6 fen. Strain and take warm on an empty stomach. If stool is not passed, take again in the evening.
For treating intestinal stagnation, bowel obstruction, and qi rushing upward due to congestion, take the Daji Wan (Euphorbia Pill):
