Cornus sericea
Arbuste natif d’Amérique du Nord largement utilisé par les peuples autochtones comme médicament et pour la fabrication d’arc ; écorce et baies utilisées contre la douleur, la fièvre et les troubles cutanés.
Cornus sericea (red osier dogwood) is a North American shrub traditionally used by Indigenous peoples for pain, fever, and skin conditions. Its bark and berries contain iridoid glycosides (cornin, sweroside), tannins, and flavonoids, which contribute to its anti-inflammatory, antipyretic, analgesic, and antidiarrheal properties. Evidence is limited to preliminary studies and traditional use, placing it at evidence level C.
The iridoid glycosides, particularly cornin, are thought to inhibit cyclooxygenase (COX) enzymes, reducing prostaglandin synthesis and thereby exerting anti-inflammatory and analgesic effects. Tannins in the bark provide astringent properties that may reduce diarrhea by precipitating proteins in the intestinal mucosa. Flavonoids contribute additional antioxidant and anti-inflammatory activity through modulation of NF-κB and other pathways. The antipyretic effect likely involves central COX inhibition similar to salicylates.
