Safety Overview
1.Bilva — Plant Snapshot
Aegle marmelos, widely recognized as Bilva or Wood Apple, is a distinctive deciduous tree belonging to the Rutaceae family, known for its significant botanical and medicinal attributes. This medium-sized tree typically reaches heights of 10 to 15 meters, characterized by a robust, often gnarled trunk that supports a broad, spreading canopy. Its foliage consists of glossy, dark green trifoliate leaves, each measuring approximately 10-20 cm in length, bearing a resemblance to the leaves of orange trees. Between April and June, Bilva produces small, intensely fragrant flowers that range in color from pure white to a pale yellow hue.
The most remarkable feature of Aegle marmelos is its fruit – a woody, round to oval structure, typically 10-15 cm in diameter, which matures into a greenish-yellow color and emits a strong, sweet aroma upon ripening. The interior contains a fibrous, pulpy, and edible substance embedded with numerous seeds. Predominantly found in tropical and subtropical climates, Bilva is indigenous to the Indian subcontinent, Sri Lanka, and various Southeast Asian nations. It thrives in diverse environments, including dry deciduous forests, scrublands, and even wastelands.
Ecologically, Aegle marmelos plays a vital role by attracting a wide array of pollinators, such as bees and butterflies, thereby enriching local biodiversity. Culturally, it holds immense sacred value in Hinduism, particularly associated with Lord Shiva, and is an integral part of many religious ceremonies. In traditional medical systems, especially Ayurveda, the bark, leaves, and fruits of Bilva are extensively utilized in numerous pharmaceutical formulations due to their well-documented therapeutic properties. The tree's notable adaptability allows it to flourish in various soil types, including laterite soils and sandy loams, provided they offer adequate drainage, underscoring its resilience and widespread availability as a medicinal resource.
