Calendula Mechanism

The flavonoids in marigold can prevent the release of histamine and the production of prostaglandins. Also, this group of compounds have other effects such as stabilizing the lysosome membrane and affecting capillary permeability and resistance. The saponins of this plant can prevent the release of histamine, bradykinin and some proteolytic enzymes. As a result, the secretion of plasma and the migration of white blood cells into the damaged tissue are hindered.

There are also reports that these substances stop the growth of some bacteria and fungi. Terpene alkaloids, lactones and flavones in the essential oil of marigolds have shown antimicrobial effects.
Marigold carotenoids, especially beta-carotene, are precursors of vitamin A and contribute to the anti-inflammatory and healing effects of flavonoids and saponosides. These compounds, together with the tannins in the plant, have been reported to be effective in preventing and improving the redness and pain caused by sunburn caused by ultraviolet rays.
The effects of stimulating and strengthening the immune system have been reported from the polysaccharide part isolated from the plant.
