Safety Overview
1.Tragia — Overview
Tragia involucrata, commonly known as the Indian Stinging Nettle or Wel Kahambiliya, is a resilient perennial herbaceous plant belonging to the diverse Euphorbiaceae family. It typically grows to a height of 1 to 2 meters, characterized by slender stems that can range from green to purplish-brown. Its leaves are ovate to elliptic, generally measuring between 5 and 10 centimeters in length, and are arranged alternately along the stem.
The upper surface of the leaves exhibits a glossy dark green hue, while the underside is subtly hairy, providing a distinct texture. A notable feature, and the origin of its common name, is the presence of stinging hairs on both the stems and leaves, which cause a sharp, irritating sensation upon contact. The plant produces inconspicuous greenish-yellow flowers that cluster in axillary racemes, with blooming periods varying but often occurring throughout the warmer months.
When its smooth, greenish bark is broken, it exudes a characteristic milky sap, a common trait within the Euphorbiaceae family. Tragia involucrata thrives predominantly in the tropical and subtropical regions of South Asia, including Sri Lanka, India, and Bangladesh. It is frequently found in disturbed environments, open fields, and along the edges of forests, demonstrating its adaptability and robust nature as a 'weed.' Taxonomically, it is classified within the genus Tragia, a group recognized for both its horticultural and medicinal species.
