Pulling up the slim pant-leg, Saeril watched the princess, who seemed to pull out a vile, and chant in the Elvish language. In just a few seconds, the winged she-elf felt the pain almost disappear entirely. Once Yavanna pulled away from the spot, the elder rubbed around the spot where she initially felt the pain; as soon as she did so, there was almost nothing there, as if the injury never happened. "Dear child, you hold quite the gift", she complimented her, softly. 

She has never gotten this kind of injury before, since as an elf, she had a higher scale of awareness. It's not like she was completely immortal, albeit not physically. Elves have rarely ever got minor injuries. Those who lack grace, would most definitely receive them. This was now an opportunity to witness Yavanna's hidden talents; one of them being the gift of healing. 

Nearby, Fili was laying down a few rolls for the four of them to sleep on. He put them close together, so they could look out and guard each other.
