Athelas

Athelas is a small highly enchanted  shrub  originally  native  to  cool,  temperate coniferous forests, now widely cultivated. A tea brewed from its dark green leaves is potentially capable of curing any disease or injury while the patient is still alive, although it cannot keep or give  life. The magic of athelas is highly dependent upon the status of the healer, however, only reaching full potency in the hands of an "ordained"  king or  similar  individual. Athelas leaves and fruit are  also edible and highly nutritious, and arefrequently used in the Elven Waybread lembas.
