Silraen

Silraen was a small shrub related to heather, native to semiarid and temperate scrublands. When properly refined, silraen leaves contained an analgesic and sleep-inducing drug.Silraen was prepared by boiling its tiny gray-green leaves in water, then straining the extract.It could be used in this form, but in normal practice the extract was allowed to evaporate into powder, which had a much longer shelf life and could be measured much more accurately.The powder was then dissolved into water and ingested.Overdoses of silraen could be dangerous.For every ounce ingested over the recommended four, the user had to resist a mild nerve poison.
