Viburnum opulus
Also known as Black haw, High cranberry, Sloe, Viburnum, High-bush Cranberry, (1) Black Haw, Sloe-leaved Viburnum, Stag Bush.
Like black haw, this species of Viburnum is a uterine sedative and tonic and may be used where there is a predisposition to abortion, or as a partus praeparator. It is believed to have stronger antispasmodic properties than the black haw, and the special indication is cramps or cramp-like contraction of the hollow viscera, as well as of the voluntary musculature.

| In one of my cases it caused the womb to suspend expulsive action and to retain a dead fetus for months; given in large doses after the fourth month no return of the expulsive effort occurred until the seventh, when the agent was discontinued, after which a four-months mummified fetus was expelled without detriment to the health of the patient. |

Action and Therapy. Like black haw, this species of Viburnum is a uterine sedative and tonic and may be used where there is a predisposition to abortion, or as a partus praeparator. It is believed to have stronger antispasmodic properties than the black haw, and the special indication is cramps or cramp-like contraction of the hollow viscera, as well as of the voluntary musculature.
Action and Therapy. Black haw is a remedy of Eclectic development and is praised by practitioners of all schools of medicine for its virtues in disorders of women. It is both tonic and antispasmodic, well-sustaining the time-honored meaning of those terms.
Therapy. Given prior to labor it is a partus preparator of much value, but its action is limited largely to its antispasmodic influence upon erratic pains. It is given with much benefit in severe after-pains, in hysterical conditions, with convulsive phenomena, and in spasmodic dysmenorrhea. It is of advantage in that it prevents miscarriage., but to an extent greatly inferior to viburnum prunifolium, which agent, in fact, fully covers the field of operation of this agent, except in its anti-spasmodic influence.
Therapy. It is the remedy for dysmenorrhea, especially that characterized by cramp-like pains of spasmodic character. It promotes normal uterine contractions and antagonizes those of an irregular character. It is valuable in menorrhagia and metrorrhagia, either of an acute or a passive character.
