Aegle marmelos (L.) is perhaps one of the most esteemed medicinal plants in the Indian subcontinent with several beneficial pharmacological properties. From the past decades, regardless of the study of the chemistry of the compounds, considerable progress has also been made to study the biological activities and medicinal applications of Bael plant. In the present review, an attempt has been made to congregate all the pharmacological and phytochemical studies done on this important medicinal plant, Aegle marmelos (L.). Extensive studies show that this plant possesses various significant activities such as antifungal, antioxidant, antibacterial, antiprotozoal, antispermatogenic, anti-inflammatory, anthelmintic, antidiabetic, laxative, febrifuge, and expectorant, chemopreventive, antipyretic, ulcer healing, antigenotoxic, and diuretic. Thus it was worthwhile to review on this plant’s studies to give a bird’s eye view mainly on the activities and constituents of the plant to the scientists.
