First get the water bottle from the merchant in Lohan. He will try to sell it for a huge amount of gold, but if you keep telling him to drop the price he will give it to you for free.

Then you go to the Dragon's Nest and go to the spring, fill the bottle with water and go to the place where Shana had to rest because of the dragon's poison you will see a plant.

Walk up to it and pour the water on the plant. It should shrivel up, then just keep moving and you will get to Shirley's Shrine
