Tinctures, teas (decocted from dried bark) and fluid extracts are common preparations for this herb. Capsules have also been used.


Not generally used as an external remedy, possibly due to its potential irritant effect(?)


Do not use in children under 12, or if pregnant or nursing. Consult with a qualified health practitioner to ensure a safe dosage. Symptoms of overdose include numbness, excessive salivation, tremors and sweating. Use caution if giving to an elderly patient or someone with serious underlying health issues. Some people experience a burning sensation in the mouth when taking orally. It may interact with psychiatric medications (especially sedatives), some pain medications and muscle relaxants, among other pharmaceuticals – ask your doctor and pharmacist to be sure this is a safe choice for you.

Due to potential interactions with anesthesia, do not take this plant within two weeks of a scheduled surgery.

I suggest consulting a pharmacist or physician before starting any herbal supplement if you are taking a prescription medication or have serious underlying health concerns.

Energetic/traditional use:

Jamaica dogwood has been used as an insecticide to eliminate pests, and to poison fish (due to its content of rotenone, known to affect cold-blooded creatures).
