Properties and Benefits of Jamaican Dogwood

Jamaican Dogwood

Also known as Florida fishpoison or fishfuddle, Jamaican dogwood (Piscidia piscipula) is a tropical tree whose bark boasts powerful sedative, anti-inflammatory and pain-relieving properties. It is one of numerous dogwood species common across the United States and its bark has been traditionally used to treat a variety of ailments, from persistent cough to minor aches and pains, but also for mental health, to relieve stress and anxiety.

However, remember to always ask for medical advice before pursuing any form of alternative treatment in order to avoid side effects and potential medicine interactions. Also, know that Jamaican dogwood shouldn’t be confused with American dogwood (Cornus florida), the common dogwood (Cornus sanguinea) or with European cornel (Cornus mas), known simply as dogwood. Despite having similar names, which engenders great confusion, all four plants have specific medicinal properties which limit their use to certain medical conditions. Mistaking one for another can result in failure to address a certain medical problem and may even cause complications of existing health issues.

What is Jamaican dogwood and what does it look like?

Jamaican or Jamaica dogwood is a flowering tree native to the southernmost parts of the USA, Mexico, the Caribbean region and South America. It can reach heights of 10-15 meters and flowers in May, after roughly 4 years of age. The leaves are elongated and pointy, dark green on top and slightly gray-green below. It bears clusters of white flowers tinged with lemon green and red-pink which turn into 10 cm long four-winged pods. The pods ripen in July-August, releasing oval, red-brown seeds. Jamaican dogwood bark is thin, gray-brown, with numerous tiny scales. The bark of the root is the most important part of the plant, boasting several impressive medicinal properties.

What does Jamaican dogwood taste and smell like?

Jamaican dogwood bark has a bitter, strong taste and fairly unpleasant smell. Because of the high amount of tannins giving it a pungent taste, eating it generates a burning sensation in the mouth.

What is Jamaican dogwood used for?

Traditionally, Jamaican dogwood roots, bark and leaves were used for fishing. Potent sedative chemicals in the plant, such as the toxin rotenone, helped tribe hunters tranquilize fish, making them easier to hunt. The same toxins were later found to help manage several physical and psychological medical conditions in humans, namely insomnia, anxiety, muscle spasms, inflammation and pain associated with rheumatism and arthritis, migraines, even cough and fever. The root bark is the part commonly used for medicinal purposes, but only under the careful supervision of a healthcare professional so to avoid possible side effects.
