Nanjura fruit

Nanjura fruits were a fruit present on prehistoric Earth. They were very toxic to Silurians but not, at least, to Time Lords.

While on a mission to find Madame Vastra's favourite fruit for Jenny, Alice Obiefune found a Nanjura fruit, mistaking it for the fruit she and the Eleventh Doctor were looking for. The Doctor warned her about it being toxic for Vastra, adding that it was actually delicious. (COMIC: Supremacy of the Cybermen)
