In Singapore, they created a wound-healing plaster made of frog skin.

The frog collagen patch creates a porous layer in which leukocytes and healing substances stick together. It accelerates the healing of wounds, as it also serves as a barrier that retains moisture. Collagen also works as a scaffold around which nearby skin cells can gather. The patch itself breaks down over time. Collagen from frog skin is more biocompatible with humans than structural proteins from other animals.
