Oat also contains carbohydrates and triterpene saponin—the avenacin. It is extremely valuable due to its anti-inflammatory and antibacterial properties. Avenacin can also reduce swelling. Additionally, it seals blood vessels and reduces the visibility of varicose veins and broken capillaries.
Oat extract is also a rich source of alkaloids, melatonin, and phenols. It also contains flavonoids—ferulic and cinnamic acid derivatives—and mineral salts, including bio-silicon, which boosts regeneration, makes connective tissue elastic, firms the skin, and helps reduce swelling.
