A drink or drug supposedly once taken to forget sadness or troubles; anything that alleviates pain or which soothers or comforts.
Opium is important and, in one or another of its derivatives and preparations, has been for millenniums. It is mentioned by Homer, who called it nepenthe; it was a major factor in the shaping of 19th- and 20th-century Chinese history; it contributed in its way to the sensualism of Samuel Taylor Coleridge's poetry, and, of course, it is an addictive commodity traded by vast networks of criminals.

Having spent the daylight hours canvassing Nepal's capital for an article I was researching, a relaxing evening free of open sewers and wandering cows seemed the perfect nepenthe for an American unaccustomed to the unspeakable squalor the average Nepalese confronts every day of his life.

Others will find a few weeks there a sort of nepenthe, lazy day succeeding lazy day.

"Good sense alone is a sedate and quiescent quality, which manages its possessions well, but does not increase them; it collects few materials for its own operations, and preserves safety, but never gains supremacy" - Samuel Johnson
