Cogon Grass Flower Whole (Imperata cylindrica) is the dried inflorescence of the cogon grass plant, a resilient perennial widely used in traditional Chinese medicine (TCM) for its cooling, hemostatic, and diuretic properties. Known in TCM as Bai Mao Hua, this delicate, feathery flower has been treasured for centuries as a gentle yet effective herb to clear heat, stop bleeding, and promote urination. In traditional practice, Cogon Grass Flower is considered sweet and cold in nature, entering the Lung, Stomach, and Bladder channels. It is used to cool the blood and stop various types of bleeding, including nosebleeds, coughing of blood, and bleeding in the urine. It also helps alleviate fever, ease irritability, and relieve urinary discomfort caused by damp-heat. The flowers are closely related in function to the root of the same plant (Bai Mao Gen), though the blossoms are thought to be lighter and more dispersing, making them ideal for clearing summer heat and harmonizing the blood. Modern studies of Imperata cylindrica identify flavonoids, phenolic acids, and triterpenoids as key bioactive compounds responsible for its anti-inflammatory, antioxidant, and hemostatic effects. These findings support its traditional use for bleeding disorders, urinary balance, and internal heat regulation. Each batch of Cogon Grass Flower Whole (Imperata cylindrica) is carefully harvested at full bloom and air-dried to preserve its soft texture, pale color, and natural medicinal compounds. When decocted, the flowers produce a light, subtly sweet infusion traditionally used in formulas to cool the blood, stop bleeding, and clear excess heat from the body.
