Ichor
In Greek mythology, Ichor was a mineral that was present in the blood of the gods and helped keep them immortal. It was sometimes said to have been present in ambrosia and/or nectar. When a god was injured and bled, the Ichor made their blood poisonous to mortals. It was nullified by the blood of the Golden Hind, thus rendering the god mortal and it is also poisonous so it will kill them as well.See also: Mana

Ichor is also another, rarely used name for bile.
