The ancients attached great importance to intestinal therapy. In China's medical treasure house, there has long been a theory that the large intestine is the source of all diseases. The ancients said, "If you want to live long, your intestines must be clear." "If you want to be young, there will be less shit in your intestines.". As early as the 1930s, the medical community had colon dialysis and intestinal therapy. Many developed countries have started intestinal therapy, and people regard intestinal therapy as a healthy fashion and spread it quickly. As early as 1989, China had its own intestinal treatment equipment.

At the beginning of the 3rd century, Zhang Zhongjing, a famous doctor, recorded in Treatise on Febrile Diseases: "It is very effective to fill Gu Dao (intestine) with (pig bile mixed with vinegar juice), like a bird (eating a meal), and defecate overnight to eat evil things."

In the Tang Dynasty, Sun Simiao recorded the method of "boiling salt soup and filling the big hole (anus) with bamboo slips" in "Prepare a Thousand Gold Prescriptions for Urgent Care". For example, when giving first aid to a drowning person, "good wine is poured into the nose first, and then into the lower part." Through these two measures, the drowning person is urged to vomit and defecate, thus eliminating a lot of water in the gastrointestinal tract.

Gu Shicheng, a famous doctor in the Qing Dynasty, wrote the "Gallbladder Guide Method" specifically: use a pig's gallbladder, put a goose feather tube in the gallbladder mouth, tie it tightly, insert the goose feather tube into the anus, twist it, and its bile will rush into the anus and defecate. The "gallbladder guiding method" recorded in the complete book of choosing doctors can be said to be the predecessor of "Kaisailu".

In Greece in the 5th century BC, Hippocrates, the "father of western medicine", in his famous medical book "Body Therapy for Acute Diseases", specifically mentioned the prevention of diseases through intestinal conditioning-inserting a section of sheepskin hydrotherapy into the anus, gently squeezing sheepskin bags, and injecting water into the intestines for health care, thus achieving the purpose of disease prevention and health care.

Mao Zedong suffered from constipation all the year round, so he had to undergo intestinal treatment. There is an anecdote in Yan 'an era: As long as Mao Zedong successfully excretes feces, the whole jujube garden will boil, and people will tell each other and cheer.

Song Meiling and Mao Zedong are both listed as typical examples of intestinal recovery. In fact, there is a difference between two people. Song Meiling himself believes that intestinal therapy can resist aging and preserve health, and has persisted for decades. But Mao Zedong suffers from constipation all the year round, and intestinal therapy is not satisfied with it. Chairman fought all night in the south and fought in the north. He was addicted to smoking all his life, and he lived to 86 years old, which is undoubtedly inseparable from his long-term intestinal treatment for constipation. Song Meiling 106 can still maintain his amazing lightness, which is inevitably related to his insistence on intestinal recuperation. Simomo, a Taiwan Province writer, wrote in his book Beauty and Sadness-Song Meiling: "Song Meiling has such a habit, but this is an unheard-of anecdote-'intestinal therapy'. Since he was young, every night before going to bed, it was time for Song Meiling to carry out "intestinal therapy". This matter has been her habit for decades. Before taking a bath, she must have "intestinal therapy" to solve the important events of her day. -This' huge project' is basically Guo's routine work, and others occasionally take over. "
