1001 Thing You Learned From Wuxia

77 In the films : forcing the poison out using internal energy usually done in a very cool way. And nothing really embarrassing from it. But from the book The Deer and the Cauldron, pushing the poison out from the body means : vomiting and pooping unbearable stench LOL

Quote from LDJ:
Chen Jinnan took him inside and had him lying on the bed. With his left hand he pressed the Shan Zhong acupoint on the pit of Wei Xiaobao’s stomach, with his right hand he pressed the Da Zhui accupoint on his back. After a while, Wei Xiaobao felt two streams of heat slowly flowed downward and around his stomach; his body felt an unspeakable comfort, he became drowsy and fell asleep. In his blurry state, he suddenly felt an unspeakable pain in his tummy. “Aiyo!” he cried out, and woke up. “Shifu!” he shouted, “I … I want to poop!”

Chen Jinnan led him out to the door of the latrine. Wei Xiaobao had just untied his pants when the excrement spurted straight out, the stench was really unbearable, followed by a lot of vomiting from his mouth.
