 * Plants of Barren Lands
 * After completing the Daily Bread quest, Geralt can give any meat food to the elves in and around the cave. Any elf inside the cave at night will unlock Han fibers and mandrake root in return.  The elf who stays outside of the cave even at night will give entries for Honeysuckle and Bryonia instead.
 * An "Old peasant woman" around the village in Murky Waters (the one wearing a hat like the Clerks' and the female Innkeeper's)'' will mention Dandelion wanted her to tell Geralt about local herbs. She'll give entries for Ginatia, Honeysuckle, and Berbercane.  She may not appear in the village until the Daily Bread quest is complete.
