The Titicaca water frog is very large and entirely aquatic and makes its home in the high-altitude rivers that flow into Andean lake for which it is named.

In addition to being named a critically endangered species by the International Union for Conservation of Nature, the frog, according to the Associated Press, is also believed by some Peruvians and Bolivians to be a cure for human maladies as wide ranging and seemingly unrelated as asthma, osteoporosis, fatigue and a low libido.

So say some Peruvians who make a habit of turning the amphibians into “juice.”

“I always come to drink frog juice here because it’s good for the children,” Cecilia Cahuana told the AP at a frog-juice bar in Lima. “For anemia, bronchitis and also good for older persons.”
