Bilva / Bael (Aegle marmelos): Therapeutic Uses and Clinical Considerations
Bilva, also known as Bael (Aegle marmelos), is a revered medicinal plant in Ayurveda and one of the most important ingredients in classical formulations for digestive and metabolic disorders. Multiple parts of the plant—including the fruit, leaves, bark, and roots—are used therapeutically, each offering distinct actions. Bilva is especially valued for its role in digestive regulation, blood sugar management, immune support, and inflammation control.
