This rat (shown pre-treatment) had its spinal cord injured while under anesthesia (a weight was dropped on its back) and then recovered its ability to take clumsy steps 42 days after having been given a derivative of a common blue food coloring, according to a study published July 27, 2009, by the Proceedings of the National Academy of Sciences.

The therapeutic dye is still several years away from reaching emergency rooms. In the meantime, patients with spinal cord injuries might want to drink blue Gatorade for its possible healing benefits, Nedergaard said. (No other dyes are known to have the same effect.)
