Bactrian cocktail

A Bactrian cocktail was a alcoholic beverage created by the Bactrians. The Doctor commented that the beverage should have been taken in two drops on a sugar cube.

Anji Kapoor once drunk a Bactrian cocktail and had to remain in the TARDIS whilst the Eighth Doctor and Fitz Kreiner went to Entusso. Fitz later threw a Bactrian cocktail on Skarpok, which rendered him unconscious. (AUDIO: Fitz's Story)
