Jamaican Fever Bark (*Piscidia piscipula*) contains rotenone and isoflavonoids, which contribute to its traditional use as a sedative, analgesic, and antispasmodic. These compounds exert their effects by calming nerves and smooth muscles, promoting pain relief, muscle relaxation, and fever reduction.
Reported Benefits (Provisional)
Origin & History
Jamaican Fever Bark (Picramnia excelsa) is a deciduous tree native to the tropical rainforests and coastal woodlands of Jamaica and the wider Caribbean. Its bark is prized in traditional medicine for its potent bitter compounds, offering significant functional nutrition benefits, particularly for immune and metabolic support.
Research Narrative (Provisional)
Scientific research on Jamaican Fever Bark is emerging, with preliminary in vitro and animal studies exploring its traditional uses for immune support, fever reduction, and liver detoxification. Further human clinical trials are needed to substantiate these effects and establish optimal dosages.
Preparation & Dosage

Reported Mechanism (Provisional)
The primary bioactive compounds in Jamaican Fever Bark (*Piscidia piscipula*) are rotenone and various isoflavonoids, including ichthynone and piscidone/piscidin. These compounds are believed to act through narcotic, analgesic, and antispasmodic mechanisms, calming nerves and smooth muscles to induce sedation, relieve pain, and reduce spasms. Rotenoids may also contribute to muscle relaxation, while isoflavonoids offer mild sedative and anti-inflammatory effects.
Clinical Narrative (Provisional)
Clinical research specifically on Jamaican Fever Bark (*Piscidia piscipula*) for its traditional sedative, analgesic, and antispasmodic properties is currently limited. Preliminary in vitro and animal studies have explored its bioactive compounds, such as rotenone and isoflavonoids, indicating potential neuropharmacological and anti-inflammatory effects. However, robust human clinical trials are largely absent, making it difficult to establish efficacy, optimal dosages, and safety profiles in humans. Current evidence primarily relies on traditional use and preliminary mechanistic insights rather than comprehensive clinical validation.
