Fraxin is widely used in pharmaceutical and cosmetic industries due to its antioxidant and anti-inflammatory properties. It is incorporated into skincare formulations to help reduce oxidative stress and protect the skin from environmental damage, particularly UV-induced aging. In medicinal research, fraxin shows potential in managing metabolic disorders and liver-related conditions owing to its hepatoprotective effects. It is also studied for its neuroprotective activity, making it a candidate for formulations targeting neurodegenerative diseases. Additionally, fraxin serves as a biomarker in the analysis of plant metabolites and in quality control of herbal medicines derived from Fraxinus species.
