Jamaican Dogwood is a deciduous shrubby medium sized tree in the Fabaceae family native to the Carribean, Northern South America, Central America, Texas, Southern Florida, and Mexico that can grow up to 40 feet in height. Like other members of the Fabaceae family, it has compound leaves, spring blooming pink or white flowers with red stripes, and winged seedpods. It’s typically grown for it’s wood, which is used regularly in boat building. The root bark is harvested after the tree is cut down. It prefers well drained, sandy soils with some organic matter, and can tolerate being near the ocean and some brackish water conditions, but not continuous salt spray or inundation, or soils comprised entirely of sand. Once established, the tree is very drought tolerant.

It’s also useful for insomnia in the cases of anxiety, nervous tension and excitability, and pain. It’s used commonly for menstrual and tooth pain, as well as muscle spasms, especially of the back. Its sedative properties also make it useful for easing whooping cough and other spasmodic respiratory conditions. Externally, it can be used in ointments and compresses to ease the pain of inflammatory rheumatism. It has also been shown useful for treating animals suffering from inflammatory conditions and nervous fear.
Jamaican Dogwood was used for it’s sedative actions in the West Indies as a fish poison. While it’s not toxic to humans, large quantities of the herb should be avoided.
