Paralysing lip gloss
From Tardis Wiki, the free Doctor Who reference
Paralyzing lip gloss was a 51st century lip gloss owned by Captain John Hart. He used it against Gwen Cooper. The function was when a person with the gloss on, kissed another person, the person who received the kiss, began to experience paralysis and eventually died. (TW: Kiss Kiss, Bang Bang)
A similar item from the same time period, Hallucinogenic lipstick, was used by River Song. (DW: The Time of Angels)
