A small black flower with dark green leaves on its stem. A very sturdy little plant, capable of withstanding the coldest mountain slopes of Gehenna, but not appearing underground. It is possible to use it as a healing herb, because its resistant juices can be extracted and rubbed in wounds. This speeds healing and works against some poisons. The leaves carry small nettles, however, capable of giving nasty burning wounds. A good pair of gloves protects adequately.
When rubbed in a wound, Dres'nehasin juice doubles healing for that wound only. In some cases (weak poisons) it allows another saving throw if one was failed previously, this only works before the onset time has elapsed, of course. When touching the plant with bare hands, a save vs. Wands (+DEX bonus) must be made or the burns cause a -2/-10% to all manual actions (attacks, rope use, pick locks, etc.) - JS
Belief can shape the planes, yet we know there are conditions to be met in order to have a belief take effect. Living, dying, magic: all are manifestations of this basic principle.
