Neoastilbin is primarily used in the pharmaceutical and nutraceutical industries due to its strong antioxidant and anti-inflammatory properties. It has shown potential in protecting liver cells from oxidative damage, making it a candidate for developing hepatoprotective agents. Research also indicates its ability to inhibit the formation of advanced glycation end-products (AGEs), which are linked to diabetes complications and aging, suggesting its use in managing diabetic conditions. Additionally, neoastilbin exhibits anti-allergic effects by stabilizing mast cells and reducing histamine release, which may benefit treatments for allergic diseases such as asthma or dermatitis. Its natural origin and biological activity support its inclusion in functional foods and dietary supplements aimed at promoting metabolic and cardiovascular health.
