Jamaica dogwood (Piscidia erythrina/Piscidia piscipula) is best known as a traditional remedy for treating neuralgia (burning or stabbing pain along the course of a nerve), migraine, insomnia, and nervous tension. As early as 1844, Western scientists discovered that Jamaica dogwood had narcotic, analgesic, and sweat-promoting properties. Recent scientific studies have helped substantiate early findings, demonstrating that bark extracts of this plant produce sedative and narcotic effects in animals.
In addition to its medicinal uses, Jamaica dogwood has been a valuable source of charcoal and wood for building boats, and has been used in fish poisons.

In West India, Jamaican Dogwood is used as a fish poison by impairing its oxygen consumption. It does not effect humans in this manner however caution still should be used when using this powerful sedative.
