Résumé
Chamaelirium luteum, known as False Unicorn, is a perennial herb native to eastern North America traditionally used to promote women's reproductive health [PMID:41337655].
Contexte
False Unicorn (Chamaelirium luteum (L.) Gray) is a perennial herb in the Melanthiaceae family native to eastern North America [PMID:41337655].
Usages traditionnels
It has been traditionally used by Native American tribes, specifically for promoting women's reproductive health [PMID:41337655].
Composés actifs
Bioactive compounds include steroidal saponins such as diosgenin (~2.5% dry weight), phenolic acids like gallic acid (~1.2%), flavonoids including quercetin (~0.8%), and lignans [PMID:41337655]. Research has isolated 15 steroidal glycosides from the roots, including unique and previously unreported compounds, as well as cholestane glycosides and sterols [PMID:22880631, PMID:23160794].
Mécanisme d'action
Phytochemicals from C. luteum exhibit anti-inflammatory, antioxidant, and cytotoxic effects [PMID:41337655]. Specific aglycones and derivatives have demonstrated antiproliferative activity in human tumor cell lines [PMID:22880631], and certain cholestane glycosides have shown cytotoxic activity against HL-60 human leukemia cells [PMID:23160794].
Preuves cliniques
Preuve CGynecological disorders
Used in managing gynecological disorders, though clinical evidence remains limited [PMID:41337655].
Preuve DProstate cancer (animal model)
Supplements containing false unicorn (among other herbs) inhibited PC3 tumor growth in immunodeficient mice [PMID:14666653].
Interactions médicamenteuses
In vitro assays using commercial preparations of false unicorn indicated that it inhibited some human cytochrome P450 enzymes with potencies around 1 µg/mL, although it did not affect CYP1A1 or CYP2C9 at the concentrations tested [PMID:21213356].
Synthèse des preuves
The evidence is primarily based on phytochemical reviews and in vitro/animal studies; there is a lack of high-level clinical trial data for human efficacy.
