[Rune] Why does Loki's blood turn people and monsters into bigger and more monstrous versions?

As far as I understand, Loki is a god of lies and trickery, so transformations like these don't really sound like his domain to me.

Have you seen Loki's children? Loki is the father of Jörmungand (the world serpent), Fenrir (a giant wolf), and he also gave birth to Sleipnir (Odin's eight-legged horse). The guy's blood must be perfect for creating monsters.
