Culver's physic

Culver, American physician. Culver's root or physic is commonly supposed to have been named after a Dr. Culver, who presumably used the herb for medicinal purposes. The doctor has never been specifically identified. All that is known for certain is that by 1716 Culver's root was common enough for Cotton Mather to mention it in his writings, noting that it was “Famous for the cure of Consumptions.”
