Synthetic intelligent collagen
From Tardis Wiki, the free Doctor Who reference
Synthetic intelligent collagen increased the natural regenerative properties of the human body by a thousand times. It was sold over the counter on pharmacies on Titan by the 35th century. The Thirteenth Doctor obtained some for Graham O'Brien's rash, and later used it on Attila the Hun's wound in 451 Gaul. (PROSE: Combat Magicks)
