Venom (毒液) from a local scorpion (蝎子) in Cuba is being used by Cuban scientists as an effective weapon to fight cancer. The venom, with stopping pain, anti-inflammatory (炎症) and anti-cancer properties, is the active ingredient in the medicine “Vidatox 30 CH,” which can be used to treat liver, brain, lung and other cancers. The treatment has been successfully used for more than four years in humans after being first tested in biological models. Labiofam, a Cuban laboratory, has breeding (繁殖) centers for both the Red Scorpion and Blue Scorpion. Each month, some 30,000 scorpions in Las Minas town, 270 km east of Havana are made to give the venom. After two years, the scorpions are released back into their natural habitat.
Denyer Sanchez, a biologist from Labiofam, explained that the conditions are adjusted for reproduction, proved by the high number of breeding female scorpions. He said when the offspring (后代) becomes able to live in the environment, we release them because they do not have the necessary size yet to remove their venom, said Sanchez. Sanchez also said that there is still much to research on the exploitation process of scorpions, such as female death rate or the ability to survive of the released scorpions.
Cuban research on the scorpion's venom began at the end of 1980s in Guantanamo province, the island's eastern tip, where a group of biologists and doctors became interested in the stories told by the peasants about the venom's benefits. However, the first discovery was made by Cuban biologist Misael Bordier. In 2001, Bordier visited Mexico's National Autonomous University (UNAM) and presented the research progress in a professional journal. Bordier died in 2005, one year before Cuba's Industrial Property Office gave Labiofam the rights to exploit the patent related to the venom.
