Vino de Madre

Vino de Madre or "Wine of the Mother" is an ingredient most notably used in resurrection spells. Its was only ever featured once in the series when the Scooby Gang decided to bring Buffy back from the dead after her death at the end of Season 5.

Description
In order to obtain Vino de Madre, Willow had to perform a ritual in the forest in order to call on a tribute where she sprinkles some unknown powder onto the ground while chanting an incantation. In the episode "Bargaining Part 1", the incantation summons a fawn, which Willow sacrifices in order to collect its lifeblood.
