Black root (Scrophulariaceae) is a hardy perennial herb having thin stem that grows up to seven feet high. The herb bears clusters of three or even more slender spear-shaped leaves that circle the stem at its nodes. Black root produces tiny white, blue or pinkish flowers between June and September. The flowers appear in clusters of spikes, each measuring about 3 to 8 inches in length, at the stem terminals.

In 1716, when the renowned Puritan leader Cotton Mather searched for a medicine to treat his daughter's tuberculosis, he asked for black root and his request was the first documented use of the plant's name. In effect, majority of the early practitioners of herbal medicine were familiar with black root and considered the herb to be a potent laxative and emetic (any medicine that promotes vomiting). Since black root was definitely an aggressive medicine for treating a lung illness, Mather's daughter died soon after using this remedy.

Native Indians of North America who found out the therapeutic qualities of the herb used black root in their ceremonies also. The Seneca Indians used this herb for ritual purifications to induce vomiting. For this they drank an herbal tea prepared with the dried out root of the herb. Another Native American tribe, Chippewa, employed the root in the form of a blood sanitizer.

The fresh root of black root is violently laxative and may even be emetic. However, the dried or dehydrated root is gentler and less violent. Leptandrin, a tincture prepared with the root of the herb, mildly stimulates the liver and, at the same time, encourages bile secretion with no irritation of the bowels or purging.

It is said that the dehydrated root of the herb has been successfully used in treating leprosy as well as cachetic (common ill health with thinness, generally occurring together with cancer or a unceasing infectious ailment) diseases as well as in conjugation with cream of tartar in treating dropsy (earlier known as edema).
