Kusha grass
Kusha grass (Desmostachya bipinnata), also known as Darbha or halfa grass, is a perennial tufted rhizomatous grass belonging to the Poaceae family, characterized by erect culms reaching up to 150 cm in height, linear leaves 10–30 cm long that are flat or rolled, and dense panicles of inflorescences up to 60 cm long.[1] Native to arid and semi-arid regions across Africa, the Middle East, and South Asia—including countries like India, Pakistan, Iran, and Egypt—it thrives in saline, sodic, and drought-prone soils such as wastelands, grasslands, and deserts.[2] In Hinduism, Kusha grass holds profound sacred status, symbolizing purity and serving as a conduit for spiritual energies in Vedic rituals, where it is believed to purify offerings, spaces, and participants by warding off negative influences.[3][4] It is commonly used to fashion rings (pavitra) worn on the right ring finger during prayers and yajnas to enhance focus and protection, as well as mats for seating during worship to connect the devotee with divine forces.[3] Additionally, strands are placed in food and water vessels during solar or lunar eclipses to prevent spoilage, a practice supported by scientific observations of its antimicrobial properties stemming from unique nano-patterns on its blades that trap bacteria.[4] Beyond religious contexts, Desmostachya bipinnata has practical applications, including thatching roofs, crafting mats and baskets, and stabilizing soil in erosion-prone areas due to its extensive rhizome system.[1] Its ecological role in binding sandy soils and tolerating high salinity makes it valuable for land reclamation in tropical dry biomes, while traditional myths in Hindu texts like the Puranas attribute its sanctity to divine origins, such as drops of nectar (amrita) from the gods.[2][3]Taxonomy and description
