Jamaican Dogwood Bark

Jamaica (or Jamaican) dogwood (Piscidia erythrina or Piscidia piscipula) has been used as a traditional remedy for treating nerve pain, migraine, insomnia, anxiety, fear, and nervous tension. As early as 1844, Western scientists discovered that Jamaica dogwood had pain-relieving and sweat-promoting properties. More recent scientific studies have also shown that bark extracts of this plant have anti-inflammatory, sedative, and antispasmodic (helps relieve smooth muscle spasms along the digestive tract) effects in animals. This herb also contains a substance known as rotenone that has been used in insecticides to control lice, fleas, and larvae. The bark is also used in the treatment of anxiety and fear, for sleep problems (especially sleeplessness due to nervous tension). It is also used for painful conditions including nerve pain, migraines, and menstrual cramps. However, Jamaica dogwood is potentially toxic and should not be consumed by humans without appropriate medical supervision. Other applications and uses may apply.
