Detailed description
Ash, Fraxinus excelsior, a tree in the Oleaceae family, is widespread in temperate regions of Europe and Asia. Its leaves have been used for centuries for their benefits to joint and metabolic well-being.
Rich in bioactive compounds such as polyphenols, flavonoids, tannins and coumarins, ash leaves help protect cells against oxidative stress. These molecules, renowned for their antioxidant properties, support natural defense mechanisms and promote metabolic balance.
Studies have shown that ash leaf extracts also have properties for modulating the immunomodulatory response. They also help relieve mild joint discomfort. In addition, these leaf extracts support sugar regulation through their action on glucose metabolism.
Ash leaves are also recognized for their effect on renal water elimination, contributing to the natural management of body fluids. Thanks to their versatile properties, they are often incorporated into formulations dedicated to joint well-being, metabolic balance and renal health.
