What is "samanu"

Samānu, from sāmu or “red,” disease, inscribed sa-ma-ná, was an ancient Mesopotamian name for an affliction of humans, animals and plants alike and the incantation used to cure it: SAG.NIM.NIM TI.LA. It was known as the “hand of Gula.” Extant in Sumerian copies from the Old Akkadian and Ur III eras and with Akkadian translations from neo-Assyrian and neo-Babylonian periods, it is one of the few texts which is known in its various stages of evolution.
