Botanical Description
Imperata cylindrica is a perennial grass growing 0.3-1.5 m tall from an extensive network of creeping rhizomes. Leaves are flat, erect, linear, 20-120 cm long and 3-18 mm wide, with sharp, cutting edges and a prominent midrib. The inflorescence is a cylindrical, silky white, feathery spike 5-20 cm long due to long, silky, silver-white hairs on the spikelets. The rhizomes are slender, white to yellowish, and penetrate deeply into soil. In TCM, the dried rhizomes (Bai Mao Gen) are used, sweet-tasting when fresh.
Open, disturbed habitats, grasslands, roadsides, forest clearings, and degraded land; native to tropical and subtropical regions of Africa, Asia, Australia, and southern Europe; one of the most widespread grasses in the world.
Imperata cylindrica is one of the most problematic invasive grasses worldwide, classified as one of the ten worst weeds in the world. It has colonized large areas of disturbed land throughout tropical regions. No conservation concerns; the concern is rather about its invasive spread.

It is applied for Blood Heat bleeding conditions including nosebleeds, blood in the urine, and coughing up blood, as well as for fever-induced thirst, nausea from Stomach Heat, and edema from urinary difficulty. Its pleasant taste and gentle action make it one of the most suitable blood-cooling herbs for use as a daily medicinal tea or beverage.
