A Brief History of Nopal Cactus

Nopal Cactus Leaves

The Nopal cactus, and the fruit it bears, has been around over 12,000 years. It has been eaten, through this time, for its dietary benefits. The Nopal cactus is also known as the “prickly pear” and its fruit, which is actually the prickly pear, is also known as a cactus pear, Indian fig, etc. This fruit is formed when the flowers of the cactus wither away and is known as “Tuna” in its native Mexico. The Nopal cactus grows so well in Mexico because of the nutrient rich volcanic soil. The flat pads of this cactus are actually the stems for the flowers, which become the fruit. These pads can grow in size of from four to 16 inches long and up to nine inches wide and ¾ inch thick. They are used as vegetables and can be sliced, diced, etc. The white needles can be an inch long and the little short, furry looking ones on the fruit are not furry – they are very sharp and will plunge into the skin with a mere touch. More than a hundred species of this cactus exist and each has it own flavor of fruit. They all contain large amounts of vitamin C. One fruit has about 1/2 the amount of an orange.
