Rosa canina · PhytoNexus

01 Identity and provenance

Accepted binomial: Rosa canina
Common names: Rosehip
Family (APG IV): Rosaceae
Part used: Fruit
Verification tier: Tier 1 · chemistry only Taxonomy, plant part and marker chemistry are populated and stable. The clinical columns are deliberately empty because no primary source has been retrieved for them yet. Interactions shown below are rule predictions from the constituent chemistry, not clinical findings.
Reviewer note (2026 audit): TIER 1 populated (name, family, part, constituent class, marker) - stable taxonomic/phytochemical facts. TIER 2 columns (analogue, application, brand, interactions, side effects) left blank BY DESIGN - populate only from retrieved primary literature. Do not use clinically until Tier 2 is filled and a reference is recorded.

02 Constituent chemistry

Chemical class	Marker compound	Synthetic analogue in use
Vitamin C, galactolipids	Ascorbic acid Fruit	none listed

The analogue column is what makes the interaction reasoning tractable: where a constituent has a marketed structural counterpart, the counterpart's interaction profile is the starting hypothesis for the plant.

03 Stated application

Left empty by design — this is a Tier 1 entry, and the clinical columns are only populated once a primary source has been retrieved for them.

04 Interaction matrix

Predicted from constituent chemistry

These edges are not clinical findings. Each one is a rule inference: a constituent class in this plant is known to act on a target that the drug class also acts on. They are shown because a blank cell reads as “safe”, and for a Tier 1 entry a blank cell only means “not yet looked at”. Treat them as a literature-search agenda, not as a warning.

Chemistry of this pair. High-dose ascorbate acidifies urine, enhances non-haem iron absorption and can interfere with point-of-care glucose oxidase assays. Class mechanism. Hypoglycaemic botanicals act through insulin secretagogue, insulin-sensitising, alpha-glucosidase-inhibiting or glucose-transport routes. Added to a titrated pharmacological regimen the effects summate rather than plateau. Expected Symptomatic hypoglycaemia, sweating, tremor, confusion; severe events reported with insulin and sulfonylureas. Management Increase self-monitoring frequency for 2 weeks after starting or stopping. Anticipate a downward dose adjustment of insulin or sulfonylurea.

Chemistry of this pair. High-dose ascorbate acidifies urine, enhances non-haem iron absorption and can interfere with point-of-care glucose oxidase assays. Class mechanism. Tannins, phytates, oxalates and mucilage form insoluble complexes with divalent and trivalent cations in the gut lumen, reducing absorption of both the mineral and any co-administered chelating drug. Expected Failure of iron-deficiency correction, unexplained non-response to oral iron or calcium. Management Separate mineral doses from tannin- and fibre-rich botanicals by at least 2 hours; take iron with ascorbate instead. Onset unspecified Evidence D - in silico rule prediction only Find evidence for this pair Map this mechanism

05 Hazard register

The audit recorded no hazard beyond the interaction profile. The controlled-vocabulary field reads not assessed, which means the assessment has not been done rather than that it came back clear.

06 Confusable material

These entries could be mistaken for this one in trade, in the herbarium, or in a prescription. Powdered material is often indistinguishable, so the check is macroscopic, microscopic and chromatographic rather than nominal.

09 Isomechanistic neighbours

Species whose interaction profile overlaps this one, ranked by shared severity weight rather than by count — a shared contraindication counts for more than a shared minor signal. Practical use: these are the plants you should not stack with this one, because the mechanisms summate.

10 References and notes

No citation is on record for this entry. That is itself the finding: the audit flagged it, and it is why the entry does not carry an A evidence grade.
