Frogs from Peru's Lake Titicaca are the main ingredient in a juice blend that some Andean cultures believe has the power to cure asthma, bronchitis, sluggishness and a low sex drive.

To make the mix, which is sold in Peru's Andes and the capital Lima, vendor Maria Elena Cruz kills a frog, peels off the skin and drops it into a blender with carrots, the Peruvian maca root and honey.

The juice is a greenish colour and Ms Cruz serves it in glasses to her customers.

"Frog juice is good for anemia, bronchitis, bones, the brain, fatigue, stress and it is mostly children, adults, persons with anemia, respiratory issues and sometimes tuberculosis" who come to her stand, she said.
