Opuntia matudae, or xoconostle, is a cactus native to Mexico.

[2] Opuntia matudae is the most commercially important species of cactus referred to as 'xoconostle'.

[4] The cactus fruit is consumed as a traditional medicine and food in Mexico.

[4] In contrast to the common fruit (tunas) from related Opuntia ficus-indica, it is less sweet, the color is a bland greenish, and it is more used for traditional medicine than cuisine.

It has many green seeds in the central pit which is covered in red pigment from its antioxidant betalains.
