The most common Opuntia (prickly pear) in Erath County is Opuntia engelmannii. Natives used every part of this cactus, including the stems, flowers, fruit, seeds, thorns, and sap. Of all the native plants of Texas, the prickly pear has been most responsible for keeping humans and animals alive during times of deprivation. The most obvious feature is the flat, oval pad, this is the stem, known as the cladode. The cladode has been an important food source and healing agent throughout human history in Texas. After the spines are burned off, the pads are ready to eat by boiling, steaming, roasting, or if they are new (nopalitos), they can be eaten raw. Buried deep in dry rock shelters and caves, the pads have been found that were split laterally and then sewn together again to form pouches. The pads were then used as steaming pouches for cooking meat, they have been found with different kinds of meat, fish, and even lizards inside. The name for this cooking process has been lost in Texas, but the Aztec name is mixiote (mee-sho-tah). The prickly pear pads were also used as a topical healing agent used to treat wounds, sores, swellings, and insect bites. The pad was split and the mucilaginous side was placed over the wound as a poultice. The antiseptic gel was used to stop the bleeding and reduce inflammation. The use of this healing method was learned by the Comanches from more ancient folk when they spread into Texas in the early 1700s. The Hispanics learned the technique from them and later the treatment became standard practice among early Anglo settlers as well. I have read in several places that this treatment was used successfully to treat serious bullet and arrow wounds. The prickly pear in the background is the Opuntia ficus-indica, the thornless variety developed by the Aztecs, the photo was taken in my garden, started from a cactus in Gene Porter’s garden over 40 years ago.
