Venom from a scorpion native to Cuba, Rophalorus junceus, is being used by scientists as an effective weapon against cancer.

The venom, with analgesic, anti-inflammatory and anti-tumor properties, is the active ingredient in the homeopathic medicine Vidatox 30 CH, which can be used to treat cancers in the breast, liver, brain, prostate and lungs.

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 centers for both the Red Scorpion and Blue Scorpion.

Each month, about 30,000 scorpions in Las Minas, 270 km east of Havana, undergo a stimulation process, in which they receive a 20-millivolt electric stimuli to remove the venom. After two years, the scorpions are released back into their natural habitat.

Denyer Sanchez, a biologist from Labiofam, explained that the conditions of captivity are tailored for reproduction, proved by the high number of breeding female scorpions.

"When the offspring, which we call nymphs, become able to live in the environment, we release them because they do not have the necessary size yet to remove their venom," Sanchez said.

Sanchez also said that there is still much to research on the exploitation process of scorpions, such as female mortality or the ability of the released specimens to survive.

Cuban research on the scorpion's venom began in the late 1980s in Guantanamo province, on 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.

The story is broadcast by Roger Ryan.
