Opuntia indica is a succulent plant belonging to the Cactaceae family. Native to Mexico, it now grows wild in many warm regions around the world, especially in the Mediterranean basin, including southern Italy. It is easily recognizable by its flat, green, and fleshy pads (called cladodes), which are covered with small spines. In summer, it produces large yellow flowers that turn into edible fruits known as “prickly pears,” with sweet, juicy flesh rich in seeds. This plant is highly resistant to drought and thrives even in poor, rocky soils. It is used in both the food sector (for its fruits and young pads) and in medical, agricultural, and ecological fields, thanks to its beneficial properties and its ability to protect soil from erosion.
