Cactus species, particularly Opuntia (prickly pear) and Nopal, have a long tradition of use in various cultures, especially in Mexico and parts of Central America, for supporting digestive health and soothing the stomach. Traditionally, the mucilaginous (gel-like) interior of cactus pads has been consumed to help with gastritis, gastric discomfort, and to promote general stomach health. Ethnobotanical records show that indigenous peoples have used cactus preparations to alleviate symptoms such as indigestion, heartburn, and even gastric ulcers.

From a scientific perspective, there is limited but emerging evidence that certain cactus extracts, particularly from Opuntia species, may have gastroprotective properties. Some in vitro and animal studies suggest that cactus mucilage can help protect the gastric mucosa by forming a protective layer and possibly reducing inflammation. However, robust clinical trials in humans are lacking, and the available scientific data are not sufficient to fully validate traditional claims. Therefore, the use of cactus for stomach health is primarily justified by traditional use, with the scientific support being preliminary and not yet definitive.
