Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Fragrant Angelica 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.
Linear furanocoumarins such as imperatorin and xanthotoxin are established mechanism-based inhibitors of intestinal CYP3A4. Piperine inhibits the same enzyme and P-glycoprotein. Stacking two inhibitors raises exposure to anything else in the formula that is a CYP3A4 substrate. This is a formulation caution rather than a benefit to seek.
Hyperforin activates the pregnane X receptor and increases CYP3A4 expression over days to weeks. Angelica furanocoumarins inhibit the same enzyme within hours. Combining them produces a moving target for anything metabolised by that route. Both also carry photosensitising constituents, which adds a second reason not to stack them.
Angelica sinensis and the aromatic European and Japanese Angelica species share ferulate esters and coumarin scaffolds, though their profiles are not identical. Traditional formulas combine related Angelica species deliberately. What stacks is the coumarin load, including the photosensitising fraction. Anyone counting furanocoumarin exposure should count both.
Licorice appears in a large share of traditional multi-herb formulas containing Angelica, positioned to soften the harshness of the other ingredients. The rationale is empirical formulation practice rather than an identified molecular interaction. Glycyrrhizin does have real pharmacology of its own on potassium and blood pressure. Count that separately rather than assuming it is inert filler.
Angelica root is used for its bitter aromatic effect on digestion, and ginger is the conventional partner for that role. Both act on gastric emptying and smooth muscle tone. The combination is documented as practice rather than tested as a pair. It does not change coumarin exposure.
Angelica root and seed oil is rich in monoterpenes such as alpha-pinene that oxidise readily on exposure to air and light. Rosemary extract is a common antioxidant addition to slow that. Oxidised terpene fractions are the more sensitising ones, so this is about material stability. The pairing is formulation convention.
Silymarin has weak inhibitory activity on several CYP isoforms and on glucuronidation. Angelica furanocoumarins inhibit CYP3A4 more decisively. Putting both in one formula compounds an already hard to predict effect on co-administered substrates. The interaction is mechanistic and has not been characterised for this specific pair.
