Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Nut Grass 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.
Cyperus rotundus tuber, known as musta in Ayurveda and xiang fu in Chinese practice, is conventionally combined with ginger in carminative preparations. Both contribute lipophilic terpenoid volatile oils. The pairing rests on traditional use and shared chemistry, not on trial data for the combination.
Licorice appears in a large share of traditional decoctions containing the tuber, where it moderates bitterness and acts as the conventional harmoniser. Glycyrrhizin is also a mild surfactant, which may help disperse lipophilic constituents in an aqueous decoction. The pairing is formulation convention with a plausible physical basis.
Xiang fu and dang gui appear together in several classical gynaecological formulas. The rationale is traditional rather than mechanistic, and no controlled work isolates the pair. Recorded here as documented formulation practice.
Cyperene, alpha-cyperone and cyperotundone are volatile sesquiterpenes with very low water solubility. A water decoction extracts only a fraction of them, while a lipid vehicle or an oil-filled capsule carries far more. This is solubility chemistry, and it explains why essential oil and decoction preparations behave differently.
Piperine raises systemic exposure to many co-administered lipophilic compounds by slowing their metabolism, which is why it is added to terpenoid and polyphenol products. The same mechanism raises exposure to constituents whose dose-response is not characterised. Read it as a change in exposure, not automatically an improvement.
Terpenoid essential oils relax intestinal smooth muscle in laboratory tissue preparations, and combining two of them adds to that load. Peppermint oil has far more human data behind it than the tuber does. Anyone using both should count the total volatile oil intake and expect reflux as the common limiting effect.
Curcuminoids and sesquiterpenes share the same formulation problem and the same solutions: lipid carriers, emulsification or particle size reduction. They are also traditional co-ingredients in Ayurvedic digestive preparations. The shared point is delivery, not a demonstrated combined effect.
Chamomile contributes bisabolol and chamazulene, the tuber contributes cyperene-type sesquiterpenes, and both classes show smooth muscle and central effects in laboratory models. Combining them raises the total terpenoid load in a blend. The pairing is a formulation choice with limited human evidence on either side.
Whole tuber powder carries substantial starch and fibre alongside the volatile oil, so it behaves partly as a food matrix. Products combining it with amylase and lipase follow the traditional practice of dosing around meals. This is a formulation convention, not a demonstrated interaction.
