Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Chekiang Fritillary 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.
Zhe Bei Mu appears repeatedly beside gan cao in classical respiratory formulas, where licorice is used as a harmonising and demulcent component. The pairing is documented in the formula literature rather than in controlled trials. Read it as traditional formulation practice, not as a tested combination.
Both appear in formulas built around throat and airway comfort, one as a bulb alkaloid source and the other as a volatile menthol carrier. Their proposed actions are unrelated at the molecular level. Nothing in the controlled literature separates the pairing from its parts.
Marshmallow supplies polysaccharide mucilage that coats mucosa physically, while the fritillary bulb contributes isosteroidal alkaloids. The two act by completely different routes, which is why they are combined rather than substituted. The combination is formulation convention.
Fritillaria is named in the traditional eighteen incompatible pairs opposite aconite species, a prohibition carried in the Chinese materia medica for centuries. Modern pharmacological work on why is limited and not settled. Whatever the mechanism, aconite preparations carry serious cardiac toxicity in their own right and are not something a consumer should be combining with anything.
The bulb is mostly starch by weight, and the alkaloids of interest sit at fractions of a percent. Amylolytic processing steps are used industrially to break the starch matrix and raise recovery during extraction. This is a manufacturing observation rather than something that happens usefully in the gut.
