Ardûvar

Arduvaar is a shrub related to  mesquite, native  to deserts  (but not  dune seas) and  semiarid regions. When properly  refined,  arduvaar leaves  contain   an  extremely   powerful  universal   antidote.Arduvaar is  prepared by  boiling its  tiny gray-green  leaves in strong alcohol,  then straining  the extract. It may be used in this form, but in  normal practice  the extract  is  allowed  to evaporate into powder, which has a much longer shelf life and can be measured  much more  accurately. The powder is then dissolved into wine or  spirits  and  ingested.Even  small overdoses of  arduvaar are  dangerous.
