Indonesia is known as a country rich in biodiversity, including various types of plants that have extraordinary benefits. One of the plants that is often underestimated yet holds great potential is cogongrass (Imperata cylindrica), especially its roots. This research aims to delve deeper into the various benefits of cogongrass roots, from health, economic, agricultural, to environmental aspects. The method used is a descriptive literature study by reviewing various relevant scientific literature sources. The study results show that alang-alang roots contain active compounds such as flavonoids, saponins, and tannins that have traditional medicinal properties, such as reducing fever, facilitating urination, and stabilizing blood pressure. In addition, the innovation of processing these roots into modern products such as chewing gum and herbal drink powder is considered to enhance their economic value. In the field of agriculture, cogongrass is also beneficial as organic mulch and a natural weed controller, and it can be used as a material for absorbing heavy metals in water. With its various advantages, the roots of cogongrass have the potential to become a natural solution that not only supports health but is also environmentally friendly. However, further research is still needed to ensure its safety and effectiveness as part of modern medicine. Keywords: cogongrass root, traditional medicine, herbal innovation, agriculture
