Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Figwort 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.
Figwort root carries iridoid glycosides, chiefly harpagoside and aucubin, alongside phenylpropanoid glycosides such as acteoside. Boswellia contributes boswellic acids, which act through a separate lipoxygenase-linked route. The pairing is mechanistic reasoning plus long formulation habit rather than a tested combination in people. No human trial of the two together has been published.
Acteoside and related caffeoyl phenylethanoid glycosides in figwort share curcumin's fate of rapid glucuronidation and sulfation in the gut wall and liver. That means both depend on the same absorption bottleneck rather than on each other. Combining them broadens the polyphenol mix without raising the dose of either. Whether measured blood levels rise has not been tested for this pair.
Willow bark yields salicin, converted to salicylic acid, a direct cyclooxygenase route. Figwort iridoids act more diffusely on inflammatory transcription. Because the endpoints overlap, someone combining them should count the total load rather than assume the two are independent. Salicylate content also carries its own platelet consideration.
Xuan Shen, the Chinese figwort root, appears with gan cao in long-standing multi-herb formulas. Glycyrrhizin is a known modifier of phase two conjugation, so it can shift how much of a co-dosed glycoside survives absorption. The direction and size of that shift for figwort constituents has not been measured. Licorice also carries its own mineralocorticoid effect at sustained doses, which is the limiting factor in any pairing.
Several Scrophularia species contain constituents with reported effects on clotting parameters, and the herb appears on caution lists for people on warfarin. Vitamin K sits on the opposite side of that same balance by driving gamma-carboxylation of clotting factors. Anyone using an anticoagulant should not be adjusting either variable without their prescriber. This is a caution flag, not a benefit pairing.
The pairing comes from classical formula construction rather than from any controlled comparison. Both plants appear in preparations aimed at circulation and tissue comfort. Dang gui contains coumarin derivatives of its own, so the combination compounds the anticoagulant caution rather than cancelling it. Read this as tradition plus a caution, not as tested benefit.
