Pluchea.
Pluchea indica leaf is brewed as a tea and supplies chlorogenic acid and its caffeoylquinic relatives, the same polyphenol family that makes coffee an antioxidant source.

What Pluchea is, and what it does.
- Does it work
- Suits people who like a caffeine free polyphenol tea in a daily routine, especially anyone already drinking green tea. Human research on it is early.
- How much to take
- No dose figure is on record. It's traditionally drunk as a leaf infusion, a cup at a time, and standardised extracts state their caffeoylquinic acid content instead.
- Time to feel it
- Polyphenol intake doesn't announce itself. Antioxidant measures shift over weeks of steady intake rather than after a single cup.
- The first dose
- Day one is a cup of grassy, faintly salty tea. The polyphenols are being metabolised quietly, and the change lands in markers rather than sensation.
- With regular use
- Weeks of daily intake keep a steady flow of caffeoylquinic metabolites moving. Of 815 records at Europe PMC, most of that work is laboratory and animal.
- How well tolerated
- Well tolerated as a traditional tea. There's no pregnancy or medicine interaction data on it, so check with a clinician if either applies to you.
- How it feels
- Grassy, mildly salty and caffeine free, so no lift and no jitter. It reads as a calm herbal tea rather than something with an edge.
- The overlooked benefit
- Hot water and alcohol pull different compounds from this leaf, so a brewed cup and a tincture are not the same product even at the same weight of leaf.
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.
Pluchea indica leaf is dominated by caffeoylquinic acids and flavonoids, which sit in the same one-electron redox cycle as ascorbate. Ascorbate can regenerate the oxidised phenoxyl radical back to the parent polyphenol, so the two persist longer together than either does alone in a test tube. This is measured chemistry in solution, not a demonstrated outcome in people. Formulators often use it as a stabiliser rationale rather than a benefit claim.
Tocopherols work in the lipid phase, and the caffeoylquinic acids in Pluchea work in the water phase. Pairing them covers both compartments of an emulsion or a cell membrane boundary, which is why phenolic extracts and tocopherols are routinely combined in oxidation-prone formats. The interaction is a stability argument for the product, not a measured effect in a person.
Polyphenol-rich leaf infusions bind non-heme iron in the gut lumen and lower how much of it is taken up. Pluchea is drunk as a tea in Southeast Asia and carries the chemistry that does this. Anyone using an iron supplement for low iron status is better off spacing the two by a couple of hours. This is a direction-of-effect statement about absorption, not a claim about anyone's blood values.
The same catechol and galloyl groups that bind iron also complex zinc and copper at gut pH. The effect is smaller than with iron but runs in the same direction. Separating a mineral dose from a strong polyphenol infusion by two hours removes the question entirely.
Both are polyphenol-heavy plant infusions and their mineral-binding and redox behaviour stacks rather than cancels. That matters most as a total-polyphenol consideration in a formula, since the mineral-binding downside also adds up. No human work has looked at the pair together.
Piperine slows glucuronidation and sulfation of several plant phenolics, which raises how much circulating parent compound survives first pass. Caffeoylquinic acids are heavily conjugated in the gut wall and liver, so the same handling is plausible here. Nobody has measured it for Pluchea specifically, so read it as mechanistic rather than clinical.
Nothing specific on file for Pluchea. 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 Pluchea actually does.
This leaf's chemistry is characterized by chlorogenic acid and related compounds plus flavonol glycosides, which is what standardization tests in the research literature target.
Gut bacteria break these acids down into two smaller acids, and the released caffeic acid then gets further processed by the gut wall and liver, so blood levels of the original compound stay low.
Phenolic acids like these neutralize free radicals by donating a hydrogen atom, which is the chemical basis for their antioxidant behavior in lab studies.
As a brewed leaf, what you extract is mainly water-soluble phenolics and salts, so a hot-water infusion and an alcohol tincture won't give you the same compound profile.
Where Pluchea comes from.
A coastal shrub whose leaves have been brewed as tea in Southeast Asia for generations. Supplements are usually that same leaf, dried and concentrated.
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.
A salt-tolerant coastal shrub of the daisy family, grown and wild-harvested across Thailand, Indonesia and southern China
Dried leaf is extracted, with water pulling caffeoylquinic acids and flavonol glycosides and ethanol shifting the balance toward less polar constituents
The liquor is filtered and reduced under vacuum to protect the heat-sensitive phenolic esters
Total caffeoylquinic acid content is measured and adjusted with carrier to hit a declared percentage
Powder goes into capsules and sachets, the cut leaf into tea bags, and the tincture into dropper bottles
