Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Alchornea cordifolia has none that clears that bar.
Stitching two separate single-ingredient studies into a pairing is the one thing this engine will not do. When a study of the combination itself holds up at source, it lands here with its citation.
No invented synergy. Where actives were studied on their own rather than together, the record shows each on its own evidence, never a combined effect no trial measured.
Research strength. Research strength says how much work stands behind the combination. It is never a product score.
Independent record. Every finding is cited to a named trial, dated, and never written by the brand.
20 pairings are live across the library today. Checked 20 July 2026.
No study gave these as a pair, so they are not in the card above. But the reason they belong together is settled biochemistry, not a guess, so it is worth knowing.
Ferrous sulfate is the classic non-heme iron salt and the one most affected by polyphenol binding. Taken in the same sitting as a tannin-rich decoction, a measurable fraction of the dose is bound and lost. Separating the two by a couple of hours is the standard workaround.
Ascorbate reduces ferric to ferrous iron and forms a soluble chelate that resists polyphenol binding, which is why it is the standard counter to a tannin-heavy meal. Adding it alongside iron partially offsets the inhibition from a tannin-rich botanical. It offsets rather than eliminates the effect.
Tannins bind zinc as well as iron, though less strongly. A high-tannin plant preparation taken with a zinc supplement lowers what is available for uptake. The practical answer is the same as for iron: separate the doses.
Tannins are defined by their affinity for proline-rich proteins, which is the chemistry behind astringency in the mouth and behind traditional use of these plants on tissue surfaces. Collagen and gelatin peptides are exactly that kind of substrate and will complex with the tannins. Both are diminished by the pairing.
Tannins bind and precipitate proteins in general, including pancreatic proteases and amylase, which is a well described anti-nutritional property of high-tannin plant material. Dosing an enzyme blend together with a tannin-rich decoction works against the enzyme. Space them apart if both are wanted.
The leaf carries flavonoids alongside its tannins, and quercetin belongs to the same chemical family with overlapping radical-scavenging behaviour in laboratory assays. Adding them together increases total polyphenol exposure. In vitro antioxidant activity is a chemical measurement, not evidence of an effect in a person.
Traditional West African and European herbal practice both pair astringent, tannin-rich plants with mucilaginous demulcents to soften the drying effect on mucous membranes. Marshmallow root supplies that mucilage. This is a formulation convention drawn from tradition, without controlled evidence behind the combination.
Slippery elm mucilage coats and hydrates surfaces where an astringent tightens and dries them, and the two are combined for that reason in traditional gut preparations. The pairing addresses tolerability rather than adding activity. No controlled work supports the combination.
Concentrated tannin-rich herbal preparations are metabolised hepatically and case reports of liver injury exist across the broader class of botanical extracts, which is why liver-supportive herbs often appear alongside them in traditional formulas. This is a rationale from practice, not a demonstrated protective effect. Anyone with liver concerns should be discussing concentrated botanicals with a clinician rather than stacking them.
