Black haw Viburnum prunifolum and cramp bark V. opulus act in similar ways and both have a long history of use by Native and pioneer women to prevent threaten miscarriage, relieve uterine cramps, and painful periods. Black haw is a stronger uterine relaxant than cramp bark, and large or frequent doses may lower blood pressure. The herb is also included in herbal mixtures for treating asthma. These tradition uses are born out with modern chemical analysis, both viburnums contain phytochemicals that facilitate uterine relaxation, two of which (aesculetin and scopoletin) also work against muscle spasms, and the pain-relieving salicin in the herb is also closely related to aspirin. |

 Black haw is a white flowered shrub native to North American that grows up to 30 feet tall and is found in wooded areas and beside streams. The American cranberrybush, Viburnum opulus, grows from 8 to 10 feet high with branches generally erect and smooth. The 3-lobed, broadly oval, coarsely toothed leaves are usually smooth on the upper surface, but with the veins on the lower surface somewhat hairy. The snowy white flower clusters, which appear in June, are about 3 to 4 inches across. The flowers on the outside of the cluster are sometimes an inch in diameter, but those on the inside are smaller. The red fruits, which ripen rather late in the season and remain on the bush for some time, are roundish, sour and contain a round flat stone. They bear some resemblance to the cranberry; hence some of the common names applied to the plant.
