A medical or botanical term relating to atropine or to the absence of nutrition or growth (atrophy).
From Greek 'a-' (without) + 'trephein' (to nourish), or possibly related to Atropa, the genus of nightshade plants that produce atropine alkaloid.
The deadly nightshade plant is called Atropa belladonna—named after Atropos, one of the three Fates in Greek mythology who cuts the thread of life—because it contains atropine, which in large doses absolutely does cut the thread.
