Safety Overview
1.Tephrosia — Overview
Tephrosia purpurea, widely recognized as purple tephrosia or wild indigo, is an enduring herbaceous plant within the Fabaceae family, specifically the subfamily Faboideae and tribe Millettieae. This species typically establishes a bushy form, reaching heights of 0.5 to 1 meter with a robustly branched base. Its foliage consists of alternately arranged, imparipinnate leaves, composed of narrow, oblanceolate leaflets that collectively measure 5 to 15 cm in length, often covered with fine, velvety hairs.
The plant's distinctive flowers, vibrant purple often accented with yellow, are borne in compact racemes, each bloom spanning 2 to 3 cm, effectively drawing various pollinators. Following flowering, it produces slender, linear pods, typically 3 to 5 cm long, which contain 5 to 10 seeds. The bark presents a smooth, greyish-brown texture, contrasting with its colorful inflorescence.
Tephrosia purpurea thrives predominantly in tropical and subtropical regions across Africa and Asia, including the upper Gangetic plains and western Himalayas, adapting well to dry, sandy, rocky, and loamy soils, frequently colonizing roadsides and disturbed habitats. Its rich ethnobotanical history and diverse chemical profile, featuring compounds like saponins, flavonoids, and alkaloids, underscore its significance in traditional medicine systems and ongoing scientific inquiry.
