Jamaican Dogwood.
Jamaican dogwood root bark is a traditional Caribbean evening herb, used in folk practice for winding down at night and for everyday aches after a hard day.

What Jamaican Dogwood is, and what it does.
- Does it work
- Suits people drawn to traditional evening botanicals who use them occasionally and with guidance. Anyone pregnant or on sedating medication should speak to a clinician first.
- How much to take
- No daily amount is on record, and rotenoid content is not standardised, so what a preparation delivers varies. Follow the preparation's directions and keep use occasional.
- Time to feel it
- Traditional practice points to an effect within about an hour of an evening dose. That hour comes from ethnobotanical record, since controlled human timing data does not exist.
- The first dose
- Drowsiness and a heavier, slower feeling in the evening are what people report. Numbness in the mouth or nausea means the amount taken was too high.
- With regular use
- There is no long-term human data. Traditional use is short stretches rather than months of daily bark, and with rotenoid-containing material that is a real constraint.
- How well tolerated
- It adds to alcohol, prescription sedatives and antihistamines, is not for pregnancy or breastfeeding, and its rotenoids argue against sustained high intake. Ask a clinician.
- How it feels
- Heavy and physically loose rather than mentally clear. It is not a subtle herb, and next-morning grogginess is a common report.
- The overlooked benefit
- The same rotenoids that sedate are what Caribbean fishers used to stun fish. Knowing that explains why traditional amounts stay small and use stays brief.
The proof, claim by claim.
These words describe the research, not the molecule's worth. Research strength is how much work stands behind one claim, and it is never a product score.

Why these belong in the same formula. Each row says what the basis is, from settled biochemistry through to a trial that measured the pair.
Jamaican dogwood bark and valerian root appear together in traditional Western sleep formulas. Both are sedating, and combined they produce more drowsiness than either does alone. Human data on the combination does not exist, so the caution is mechanistic and the tradition is old rather than tested.
Passionflower is one of the most common partners for Jamaican dogwood in traditional formulas. Both reduce arousal, so the sedation stacks. Anyone driving or operating machinery should assume the combination is more sedating than a single herb.
Melatonin shifts sleep timing while Jamaican dogwood contributes a general sedative load. Layered, the drowsiness compounds and morning grogginess is more likely than with either alone. Start low if combining at all.
Chamomile contributes apigenin, which binds benzodiazepine-site receptors weakly, and is a conventional partner in evening tea blends. The pairing is traditional formulation practice. No controlled human work describes the combination.
Honokiol and magnolol positively modulate GABA-A signalling in laboratory work. Stacked with a sedating bark preparation, the effects run the same direction. The magnitude in people is unknown for either ingredient at supplement doses.
Bark decoctions are commonly softened with a small amount of ginger for palatability and to reduce gastric upset. This is a formulation convention rather than a pharmacological interaction.
Nothing specific on file for Jamaican Dogwood. Match the label to the daily amount above, and tell your doctor what you take.

The root bark contains a group of compounds including rotenone plus isoflavones. Rotenone blocks a step in cell energy production and is the compound behind the plant's traditional use to stun fish.
That same blocking action reduces the cell's ability to make energy, which is the same mechanism labs use to model nerve-cell loss in research, and it's the main reason to be cautious about sustained high-dose use of rotenoid-containing bark.
Sedating plants like this one can add to the effect of other things that slow the central nervous system, including alcohol, prescription sedatives and antihistamines, whether or not they work through the exact same mechanism.
How much of these compounds is in the bark varies with plant part, harvest and preparation, and there's no standard marker compound used commercially, so the actual dose in a retail product is typically unknown.
