Safety Overview
1.Patala — Plant Snapshot
Stereospermum chelonoides, commonly known as Patala or the Yellow Trumpet Tree, is a prominent deciduous tree belonging to the Bignoniaceae family. Native to the Indian subcontinent, including India, Nepal, and Sri Lanka, its geographical range extends to parts of Myanmar and Bangladesh.
This species thrives in diverse environments, from riverine areas to dry deciduous forests, preferring well-drained, loamy soil and moderate rainfall. The tree can reach impressive heights of up to 20 meters, characterized by a straight trunk and smooth bark that transitions from a yellowish tinge in young shoots to a brownish-grey hue with maturity.
Its distinctive morphology includes opposite, pinnate leaves, typically comprising 5 to 9 lanceolate leaflets, each measuring 8-15 cm long. In spring, Patala presents a spectacular display of pale yellow, funnel-shaped flowers, approximately 5 cm in diameter, which are quite showy and trumpet-like.
These blossoms are followed by long, slender fruits. Historically, various parts of the plant, notably the bark, roots, and leaves, have been highly valued in traditional medicine systems, particularly Ayurveda, for their wide spectrum of therapeutic properties.
