Safety Overview
1.Bilva Patra — Plant Snapshot
Aegle marmelos, widely known as Bilva Patra or Bael, is a revered medium-sized deciduous tree within the Rutaceae family, renowned for its aromatic and fruit-bearing characteristics. Indigenous to tropical and subtropical regions, its native range spans across India, Sri Lanka, and Southeast Asia, where it thrives in diverse environments, from dry forests to cultivated lands. This robust species typically reaches heights of up to 15 meters, forming a moderately spreading canopy that offers ample shade. The tree's distinctive light grey bark matures over time, developing a rough, longitudinally furrowed, and characteristically fissured texture that contributes to its ancient, venerable appearance. Its leaves are a hallmark feature, predominantly trifoliate, composed of three ovate to lanceolate leaflets, each measuring approximately 7 to 15 cm in length and 3 to 6 cm in width.
The adaxial surface presents a glossy, dark green hue, contrasting with a paler, duller abaxial surface, both exhibiting prominent venation. During cooler seasons or periods of environmental stress, the foliage transitions to a vivid yellowish color before undergoing senescence. The petioles are notably short, robust, and often display a slight winged morphology. In the warmer months, Aegle marmelos blossoms with fragrant flowers, ranging from pure white to a pale yellowish-green. These small, hermaphroditic flowers, typically 2 to 3 cm in diameter, are arranged in axillary panicles or short terminal clusters.
Their sweet, musky aroma is a signature trait, attracting a variety of pollinators and signaling the tree's reproductive cycle. The fruit, a large, spherical to oval drupe akin to a grapefruit, is arguably its most iconic feature. It possesses a remarkably hard, woody outer shell that ripens to a vibrant orange-yellow. Internally, the fruit yields a fragrant, mucilaginous, yellowish-orange pulp, densely packed with numerous small, flattened, oblong seeds, each encased within a sac of clear, adhesive mucilage. The pulp becomes exquisitely sweet and aromatic upon full ripening, making it a culinary and medicinal staple.
