What does detox mean?
Detox is a modern English noun and verb referring to the process of removing toxic substances from the body. It began as an informal shortening of 'detoxification', used in medicine to describe the managed withdrawal of patients from alcohol or drugs. Over recent decades its use has broadened dramatically: it now covers dietary cleanses, juice fasts, and spa treatments that claim to flush out 'impurities', as well as figurative extensions like the 'digital detox', a deliberate break from screens and social media. As a verb, to detox means to undergo such a process, as in 'she detoxed for a month'. The word is informal but widely accepted across British and American English, and its popularity owes much to the wellness industry, where it often carries persuasive, sometimes scientifically questionable, overtones. Related forms include detoxify and detoxification, which remain the preferred terms in formal medical writing. Whether taken literally or figuratively, detox conveys renewal, restraint, and a fresh start.
A process or period of removing toxic or unhealthy substances from the body, whether through medical supervision, dietary change, or abstinence.
"The clinic's detox programme lasts fourteen days."
Originally medical slang; now common in both clinical and wellness contexts.
To undergo or cause someone to undergo a process of removing toxic substances from the body.
"He detoxed at home under his doctor's guidance."
Regular plural; used when referring to multiple instances or types of detox programmes.
"Wellness retreats now offer everything from juice detoxes to silent meditation weeks."
Detox is one of those rare words born entirely in the 20th century — clipped from 'detoxification' by doctors treating addicts, then hijacked by juice bars and wellness gurus everywhere.

Etymology of detox
Detox originated as a colloquial clipping of 'detoxification', itself formed from the prefix 'de-' plus 'toxic', ultimately derived from Greek 'toxikon' (poison for arrows). It first appeared in mid-20th-century medical slang, particularly in American contexts dealing with addiction and withdrawal. From there it spread into general usage, gaining dietary and figurative senses in the late 20th and early 21st centuries.

How detox is actually used
Informal to neutral in register; originally clinical slang for withdrawal management, now widespread in wellness and marketing contexts. The figurative sense ('digital detox') is fully established. Some health claims attached to commercial 'detox' products lack scientific support, so the word can carry a slightly promotional connotation.
