Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Lomatium 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.
Lomatium root carries coumarins and related benzofuran constituents. Coumarin-rich botanicals are conventionally flagged for additive effects on platelet function when stacked with agents that already reduce aggregation, and EPA-rich fish oil does exactly that at higher intakes. The concern is directional and mechanistic rather than measured for this species. Anyone on anticoagulant or antiplatelet medication should raise the combination with their prescriber before using it.
Nattokinase acts on fibrin directly. Adding a coumarin-bearing root to that stack pushes in the same direction, and the combined effect has not been characterised. This belongs in the caution column, not the benefit column.
Garlic constituents reduce platelet aggregation in a dose-dependent way. Stacking that with a coumarin-containing botanical compounds an effect neither one was chosen for. Worth flagging ahead of any planned surgical or dental procedure.
Both quercetin and furanocoumarin-type constituents can inhibit CYP3A4-mediated metabolism at the intestinal wall, and inhibition from two directions is not simply additive. The practical consequence is unpredictable exposure to anything else in the regimen that goes through that enzyme. Read this as a reason for caution in polypharmacy rather than a benefit.
Lomatium root appears with vitamin C and elderberry in traditional and commercial seasonal wellness blends. The pairing reflects herbal formulation custom rather than a documented interaction. Vitamin C's own contribution to normal immune function is well characterised; the root's is not.
These two are routinely combined in commercial tinctures aimed at seasonal use. No shared mechanism has been worked out and no combination study exists. The pairing is convention.
Nothing specific on file for Lomatium. Match the label to the daily amount above, and tell your doctor what you take.
Not medical advice. Show the label to your pharmacist.Read this carefully. These are 135 voluntary, unverified reactions reported to the FDA (openFDA). The number mostly reflects how popular Lomatium is, not how risky it is. A report is not proof Lomatium caused anything. It is a signal of what to watch for, nothing more.
