Flavonoids, saponins and triterpenes have anti-inflammatory, antimicrobial, antiviral and antifungal properties, that is, directed against fungal infections. Due to these effects, they are probably responsible for the wound-healing effect of marigold flowers.
The essential oil of marigold flowers also has antibacterial effects. It is also known that extracts of marigold flowers contribute to the formation of fresh connective tissue and small blood vessels on wounds (granulation tissue) and have immunostimulatory properties.
Calendula: side effects
Allergic reactions and skin inflammation (contact dermatitis) are occasionally described, especially in preparations in which the sheath calyx has been included.
