- "Calynthia powder? Is that how you keep Angel sleeping - when he's with you?"
- ―Lilah Morgan to Darla[src]
Calynthia powder was a mystical drug that augmented the victim's synapses enough to keep them in restless sleep, which also rendered the victim more suggestible.
Behind the Scenes
- A variant of Calynthia powder, referred to as "Calynthia-M", appears in the novel Stranger to the Sun, used in a plot by the vampire master MacKenna in order to alter the Earth's orbit so that one side is left in eternal darkness.
