Eyebright

Eyebright was a rare flowering herb that grew in some swamps.

Uses
Eyebright had astringent properties that made it good for treating eye infections. Skilled healers could use the flower to craft a medical ointment to treat sight rot.

It was also used as a material component for certain spells: powdered eyebright was used to prepare an ointment involved in the casting of reveal while its juice was used in casting glyph of revealing.
