Wood betony (Stachys officinalis) enjoyed a considerable reputation in antiquity and the Middle Ages as both a medicinal and a magical herb, and was believed to have many virtues. Photograph by Nathan Heavers.
In the mountains and woods, in the meadows and depths of the valleys—
Almost everywhere, far and wide, grows the precious abundance
Of betony. Yet I have it too in my garden, and there
It learns a softer way of life in the tended soil.
So great is the honor this genus has won for its name
That if my Muse wished to add to it she would find herself
Defeated at last, overwhelmed; and soon she would see
She could add nothing more to the value it has already.
Perhaps you pick it to use it green, perhaps
To dry and store away for the sluggish winter.
Do you like to drink it from cloudy goblets? Or do you
Prefer to enjoy what it gives after long and careful
Refining? Whatever your fancy, the wonderful powers
Which this herb has will supply all your needs.
