A pairing appears on this page only when a trial gave both ingredients together and measured the result. Cattail 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.
Typha pollen sits in a traditional category concerned with bleeding and blood movement, and modern pharmacology has not resolved which direction its constituents push. Pairing it with anything that affects clotting deserves attention rather than assumption. No human trial has measured the combination. Read this as a caution flag, not a recommended pairing.
Flavonoid and tannin content is the reliable part of the cattail phytochemical picture, and those compounds bind non-haem iron before absorption. Spacing an iron dose from a tannin-bearing botanical by a couple of hours sidesteps the question. The effect is on iron in the same meal only.
Cattail pollen delivers quercetin-class flavonoid glycosides as part of its native constituent profile. Combining it with isolated quercetin stacks intake of the same compound class rather than adding a different mechanism. Whether the stacked intake does anything useful has not been measured.
When a flavonoid-rich botanical and non-haem iron share a meal, ascorbate partly protects the iron from being bound. This is a mitigation of an interaction rather than a benefit of cattail. The offset is partial and depends on the relative amounts.
In traditional practice Pu Huang is a formula component, almost never used alone. Pairings of this kind reflect centuries of practice convention, not controlled comparison. Nothing here has been tested against either herb given by itself.
