Keeper:
Some of the local markets sell dethroned cactus leaves. My wife and I, take the juice from the fruit and make it into jelly. It makes very good jelly. The juice is also drinkable, and it is considered very healthy with lots of antioxidants.
I use a pair of welders gloves to pick the fruit, split the fruit in half, cover it with water and bring to a slow boil for 15 minutes. Strain the juice from the fruit, and you will have a very concentrated pink to orange juice. We only use it for jelly.
Incidentily, the fruit is called a "tuna."
My mom was one half Comanche indian, and she would cut the leaves in thin strips and boil them into a paste. The paste could then be used as a poultice to pull poison from an open wound. When it dried, it was about one-half the size of the original volume.
I will cut some in half and place them near the hives when next they bloom.
