Spearleaf

Neithlas also known as Darsúrion, the Nehtelassë, or Spearleaf, was a short, dark green grass, related to Oroluin, native to cold mountains. It was most easily identified by its blood-red leaf veins. Its leaves contained a stimulant which healed concussion hits when crushed and applied to a wound.
