Coreopsis tinctoria
Plante annuelle nord-américaine utilisée comme plante de teinture et dans la médecine navajo pour les troubles digestifs et respiratoires.
Coreopsis tinctoria, a North American annual herb known as tickseed, has a long history in Navajo traditional medicine for digestive and respiratory ailments. Modern research suggests potential anti-diabetic and digestive-supportive properties, attributed to its rich content of flavonoids, chalcones (marein, okanin), and tannins. The evidence level is C, indicating limited clinical studies supporting these uses.
The anti-diabetic effects of Coreopsis tinctoria are primarily mediated by chalcones such as marein and okanin, which inhibit α-glucosidase and α-amylase enzymes, reducing postprandial glucose absorption. Marein also activates AMP-activated protein kinase (AMPK) and enhances insulin sensitivity in peripheral tissues. The astringent tannins and anti-inflammatory flavonoids contribute to digestive support by reducing gut inflammation and modulating gut motility. Additionally, antioxidant activity from phenolic compounds may protect against oxidative stress in respiratory tissues.
