Cane toads a hearty elixir

Australian researchers have identified unique pharmaceutical properties in the cane toad which are similar to the drugs used to treat heart disease and which match those used in traditional Chinese medicine.

China is already importing toads, and the Australian find could lead to one of this country’s biggest environmental pests becoming an agricultural commodity and export success story.

The results are contained in a new report from Australia’s Rural Industries Research and Development Corporation (RIRDC) which supported the research at the University of Newcastle led by Professor Alan Boura.
Ironically it is the toxic nature of the toad’s skin and venom which could be used in medicines.

“Toad skin contains many natural agents that act as toxins to predators,” the researchers said.

“The benefits of successful exploitation of natural products as pharmaceuticals is enormous. A significant number of drugs used in clinical practice have been derived from natural sources.

“Therefore products derived from the cane toad have potential to be used in societies utilising both traditional and western medicines.”

The main thrust of the research was on the cardio-vascular effects of toad skin and venom, in line with its primary use in traditional medicine.

And although Chinese medicines have been using toad skins for thousands of years, it was the first time extensive investigations had been performed.

The researchers found that the skin contained agents similar to western drugs used to treat heart problems, although further work was needed to develop any commercial products.

But there was a word of caution, with researchers concluding that the quality control of any commercial product sold would need to be mandatory because of possible toxicity levels.
