It being that time of year when various charlatans seek to separate us from our money by convincing us that our bodies are chock-full of "toxins" that we need to "cleanse", let us look at the origins of the word "toxin".
In ancient Greek, the word toxikon had nothing to do with poison: it meant "arrow". The Greeks had another word (actually they had many other words): pharmakon, which meant "drug" and "medicine", but also... "poison". (A pharmacist friend of mine says this makes perfect sense, because if you take enough of anything, it will kill you. Good to know.)
Clearly, the Greeks were not using archery to deliver doses of medication; a toxikon pharmakon was an arrow imbued with poison. But when this term was borrowed into Latin, confusion arose as to which of the two words designated the arrow and which the poison, and thus in Latin toxicum came to mean "poison" rather than "arrow" as it should have done.
For those who believe in the etymological fallacy (the idea that a word's origin conveys its true meaning) a "detox" would therefore have to be the removal of arrows from the body, which would indeed be a good thing but certainly not achievable with a diet of wheat grass juice.
A sharply shrieked "Tom!" coming from the kitchen is a definite sounding of the tocsin, a warning to head out the back door as quietly as possible because you are obviously in serious trouble and the only safe sanctuary is the most obscure bar you can find.
A Happy New Year to all Wordlady readers, and may 2017 subject you to neither toxins nor tocsins!
