Yummy nummy frog secretions!

South American frog secretions stimulate insulin release[*1] (Science Daily):

The paradoxical frog, Pseudis paradoxa, secretes a substance from its skin which protects it from infection. But the molecule, pseudin-2, may have another use for humans. Researchers found that it stimulates the release of insulin, the vital hormone which is deficient in diabetes sufferers.

Which brings to mind the vision of millions of diabetics and pre-diabetics getting into the whole toad-licking thing.  And yeah, I know that toads and frogs are different, and that diabetes is nothing to laugh at.

Still . . .
