As soon as she did, she felt the young dwarf jolt in pain, not to mention that he was almost screaming. Where is the Kingsfoil? It was a nasty wound to see, about two inches. She had to at least draw down the pain a little before it got worse, something to delay for the Kingsfoil to come. Taking some of the feverfew, she worked quickly by putting it in water. "Hold him down", she told the other dwarves.
