Best-Effort Research Profile

Crataegus mexicana is a tree species of the genus Crataegus (Rosaceae). Authoritative taxonomic databases recognize it as an accepted species. Published research has investigated leaf and flower extracts for their phenolic and flavonoid composition, vasorelaxant activity, and antioxidant properties. Findings apply to specific plant parts and preparations rather than to a standardized single chemical entity.

Source review pending. This descriptive profile is shown from the available source material as a best-effort educational reference. It has not passed the full verification bar and is not a dosing instruction, medical claim, or treatment recommendation.

Research Profile

Reported Research Effects

Leaf extracts demonstrated vasorelaxant activity in an ex vivo rat-aorta model in a study of quantified C. mexicana preparations.
C. mexicana leaf extracts were chemically characterized with (-)-epicatechin and rutin investigated as analytical markers.
Flower extracts from Mexican Crataegus accessions contained quercetin glycosides and showed antioxidant or radical-scavenging activity in laboratory assays.
A published case report associated oral ingestion of C. mexicana root material with cardiotoxicity, respiratory depression, altered mental status, and a falsely elevated digoxin measurement; this is an adverse-exposure report and not evidence of a standardized therapeutic effect.

Research Notes

Research has primarily evaluated extracts or plant materials rather than a standardized pharmaceutical preparation. The 2021 leaf-extract study used rat-aorta vasorelaxation assays and analytical quantification of (-)-epicatechin and rutin; reported concentrations and experimental conditions belong to that study preparation and should not be generalized to the species as a whole. No reliable species-level half-life, onset, solubility, storage specification, or standard reference size was identified. Root exposure has been associated with toxicity in a case report.

Supplementary research context only. Not medical advice or a treatment recommendation.

Registry Identifiers

Accepted scientific name: Crataegus mexicana Moc. & Sessé ex DC.; taxonomic rank: species; family: Rosaceae; genus: Crataegus; ITIS Taxonomic Serial No.: 836473; native range: Mexico to Guatemala.

Source-Backed Observations

This record represents a botanical species, not a single purified compound. Chemical composition and biological activity may vary according to plant part, geographic source, extraction method, and preparation. Reported synonyms and common names may reflect differing taxonomic databases.
