Slippery Sticks
Slippery elm trees are named for their inner bark, which is moist and slippery. American Indians used the bark to reduce swelling and take the venom out of a bite or sting. It is still used today to make throat lozenges.
Antifreeze
The wood frog uses glucose in its blood as a sort of antifreeze, protecting vital organs from damage while the rest of the body freezes solid.
