Aqua Galatia

Aqua Galatia was a type of poison. It was used to kill Wolfgang Amadeus Mozart. Mozart's wife, Constanze, held back its effects with her love, but not for long.

Brooke 1 used it to try and kill the Fifth Doctor. Her efforts were unsuccessful. (AUDIO: A Requiem for the Doctor)

May have been inspired by Giulia Tofana's Aqua Tofana which she sold to woman who needed to kill their husbands. It was often disguised as makeup.
