“M. Chabas in his supplement to the Harris Magical Papyrus gives many instances of the good and evil uses made of the KHOU.

One entered the body of a princess who was obsessed for a long period, until it was cast out by means of the health-giving Divinity.

It was the KHOU which had been degraded that became a demon and the torturer of mankind.” [via]
