Empresstree.
Bark and flower extract from a fast-growing Chinese tree, carrying flavonoids and phenylethanoid glycosides. Human study is essentially absent, so what's known is chemistry.

What Empresstree is, and what it does.
- Does it work
- It suits people exploring traditional East Asian botanicals. Anyone who wants a body of human evidence behind an ingredient will find this one at an early stage.
- How much to take
- No amount is on record and no human study has set one. Traditional preparations use a bark or flower decoction rather than a measured extract.
- Time to feel it
- Nobody has measured a time course in people. Traditional use runs as a course over days rather than as a single dose.
- The first dose
- Day one passes without a noticeable effect. Gut bacteria are breaking the phenolics down long before much reaches your bloodstream.
- With regular use
- No human study has followed repeated use. What can be said is chemical: the phenolic content and how the microbiota handles it.
- How well tolerated
- Human tolerance data is thin, which is the honest position. Avoid in pregnancy and breastfeeding, and ask your clinician if you take other medication.
- How it feels
- Astringent and faintly floral in the mouth. Beyond the taste, no subjective effect has been documented in people.
- The overlooked benefit
- Its catechol phenolics bind iron and copper in the gut, so taken in the same sitting as an iron supplement it lowers iron uptake. Space them apart.
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.
Phenolic-rich botanical extracts bind non-heme iron in the gut lumen and lower its uptake. Paulownia preparations carry catechol-bearing phenylethanoids, so the same chemistry applies. Separating an iron dose from a phenolic botanical by a couple of hours is the standard way around it. The effect is on absorption, not on iron status directly.
Both materials deliver a broad phenolic fraction handled by the same phase II conjugation enzymes and gut microbial pathways. Stacking them raises total phenolic exposure without adding a distinct mechanism, and it also stacks the same iron-binding and bitterness issues. There is no human work on the combination. Read it as a formulation consideration.
Nothing specific on file for Empresstree. Match the label to the daily amount above, and tell your doctor what you take.
Not medical advice. Show the label to your pharmacist.What Empresstree actually does.
Empresstree bark, flower and fruit contain several types of phenolic compounds that can donate hydrogen atoms to neutralize free radicals, which is the standard chemistry behind antioxidant readings in lab dish tests.
One class of its compounds isn't well absorbed as-is, gut bacteria break it down into smaller phenolic acids first, so what actually reaches the bloodstream is mostly those bacterial breakdown products, not the original compound.
Certain phenolic compounds in this plant bind iron and copper in the gut, which is why phenol-rich botanicals like this can reduce mineral absorption when taken at the same time as a meal containing them.
Where Empresstree comes from.
It comes from the empress tree, a fast-growing tree from China. The bark or flowers are soaked in water or alcohol, and the liquid is dried into a powder.
Made from a plant. What ends up in the capsule tracks the harvest, so batch testing and a stated marker matter more here than with a made molecule.
Bark, flowers or fruit capsules from a fast-growing deciduous tree native to central and eastern China, now widely planted for timber.
Water decoction in traditional use, ethanol-water percolation in commercial supplement production.
Marc removed, extract concentrated under reduced pressure.
Where standardisation happens at all it is usually to total phenolics or to verbascoside by HPLC. Many trade materials carry no marker specification.
Carrier such as maltodextrin is common for the dried form.
