This may have already been posted on AH. If so, sorry, if not enjoy. P.S. I would use something a little more potent. A cure against poachers? 9th September 2011 A South African game reserve has developed a treatment for rhino horns that is safe for the animals, but toxic to humans The potion is a mixture of drugs used to kill parasites on the rhinos, developed by the Rhino and Lion Reserve in Kromdraai, north-west of Johannesburg, for use on its own rhinos. The concoction is not lethal to humans, but when consumed, causes convulsion and severe headaches and includes a dye that turns even finely-ground horns neon pink when seen by airport scanners. Spokeswoman Lorinda Hern said, "The chemicals have the dual threat of keeping away both natural and human parasites... and lasts for three to four years. "However, a permanent solution would be to eliminate the demand for rhino horn altogether. According to the national parks agency Since the beginning of 2011, 279 rhinos have been killed for their horns in parks across South Africa. Poaching numbers have increased dramatically from 13 cases in 2007; an increase conservationists say that has been powered by the demand for rhino horns in Chinese medicine. The most recent myth to fuel the illegal industry is that rhino horns offer a cure for cancer and relief for stroke victims. Hern added, "Education would go a long way towards teaching consumers that rhino horn contains no nutritional or medicinal value.
