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, and upon drinking it, he claimed that he felt so rejuvenated that he could run a marathon, wrestle a Myrka and then compete in every event of the Alpha Centauri Olympics. (AUDIO: A Requiem for the Doctor)

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