Porcupines are been hunted for undigested plant material in their gut known as bezoars.

According to leading wildlife trafficking experts, the small, spiny rodents are at risk of becoming endangered across Southeast Asia. Demand is predominantly driven by China, where some believe that bezoars, which accumulate in the digestive tract, have potent medicinal properties, including the ability to cure diabetes, dengue fever, and cancer. Bezoars are sold either raw or in powdered form and may be processed into capsules. A few ounces of the substance can command hundreds, even thousands, of dollars. Most sought after is the dark red “blood” bezoar, believed to be the most potent of the several varieties. Prices for bezoars have “increased exponentially during the past few years, following recent claims of their cancer-curing properties,” according to a 2015 report by the wildlife trade monitoring organization Traffic.

The Philippine porcupine, the Asiatic brush-tailed porcupine, and the Malayan porcupine, which live throughout Southeast Asia, are all flagged as threatened and declining in number by the International Union for Conservation of Nature, the body that sets the conservation status of wildlife species. None has yet been listed as endangered, which would bolster legal protection and international awareness.
