Colon hydrotherapy
Colonic irrigation, also known as colon hydrotherapy, colonic hydrotherapy, or a "colonic", is a treatment which is used "to wash out the contents of the large bowel by means of copious enemas using water or other medication."
During a cleansing enema, liquid is introduced into the colon and retained for five to fifteen minutes. During a colonic, liquid is introduced into the colon and then it is flushed out and this is repeated until the entire colon is cleared.
Colonic irrigation has been described as an "unwise" procedure as it carries the risk of serious harm and has no proven benefit.

(1845-1916) became the strongest supporter of the idea of colon cleansing; he thought that toxins could shorten the lifespan. Over time, the concept broadened to autointoxication, which supposes that the body cannot fully dispose of its waste products and toxins, which then accumulate in the intestine.[
] In some cases, the concept led to radical surgeries to remove the colon for unrelated symptoms.[
]
Autointoxication enjoyed some favor in the medical community in the late 19th and early 20th centuries, but clinicians discarded it as advances in science failed to support its claims.[
