Saeril was already impressed though it wouldn't surprise her that Yavanna knew the ways of medicinal plant life. Not too far from behind her, the elder had to look over her shoulder a few times, though there were moments where she would help her look. That was when it hit her. Yavanna might be looking for Athelas, or Kingsfoil. This plant was highly-used back in Fangorn Forest, where they used it to heal themselves, as well as both Man and Dwarf. 

The elder was so busy helping the princess look for at least a hint of the weed to tend to Kili's wound, she then heard a controversy near the Mayor's house. "Yavanna", she called to the girl, who was searching nearby. Her Elvish ears were no mistake, so after taking the youngest's hand, she pushed her way through the crowd, and her eyes widened once she came next to the house of the Master.
