Safety Overview
1.Rasna — Introduction & Highlights
Rasna, known scientifically as Pluchea lanceolata, is a robust perennial herb belonging to the diverse Asteraceae family, often forming dense bushes that can reach heights of up to 1.5 meters. Its distinctive lanceolate leaves are glossy, elongated, and typically measure between 6 to 12 cm in length, featuring a subtly serrated margin and an alternate arrangement along the stem. The plant produces small, daisy-like flowering heads, usually clustered at the top, displaying tiny yellow florets that create a vibrant spectacle during its blooming season.
The stems are initially herbaceous but develop a slightly rougher texture as they mature. Native to the tropical belts of Asia and Africa, Pluchea lanceolata thrives in specific ecological niches, primarily wetland areas and along riverbanks, demonstrating adaptability to both full sun and partial shade conditions. In India, it is notably found and cultivated across the plains of Ganga and in the North-Western regions, including Punjab, Gujarat, and Rajasthan.
Its resilience and widespread distribution underscore its ecological significance and traditional prominence. Phytochemically, the plant is recognized for its rich composition of compounds such as flavonoids, tannins, and essential oils, which are believed to underpin its broad spectrum of medicinal properties.
