Korokorosan is a annual, tufted, erect grass, growing 0.5 to 1 meter high. Leaves are thin, linear-lanceolate, rounded at the base, acuminate, flat, 8 to 15 centimeters long, with a flowering stalk at the tip of its stem. Floral branches are numerous, opening from a central point suggesting the ribs of an umbrella. Florets are dense and tiny, with long purplish hair. Grains are trigonous.

– Originating from tropical America.

– Aqueous extract yielded phytosterols, flavonoids, tannins, phenols, carbohydrates, proteins and amino acids.
– Study for phytochemical constituents of roots yielded amino acids, glycosides, proteins, and carboxylic acids.


Parts used


– No reported folkloric medicinal use in the Philippines.
– Elsewhere, leaves paste applied externally in skin diseases.

Fodder: Elsewhere, used as fodder when young.


Study Findings
• Analgesic / Anti-Inflammatory / Toxicity Study: Study evaluated the analgesic and anti-inflammatory activity of a petroleum ether extract of Chloris barbata SW. Acute toxicity showed no sign of toxicity up to a dose level of 2000 mg/KBW. Results showed dose-dependent analgesic activity and dose-related inhibition of paw edema.
• Antibacterial / Leaves: An in-vitro screening of leaf extracts of Chloris barbata for antimicrobial properties yielded moderate antibacterial activity against some pathogenic microorganisms when compared with standard Ciprofloxacin.
• Anti-Diabetic / Anti-Hyperlipidemic / Leaves: Study evaluated a methanolic extract of leaves for in-vivo anti-diabetic and anti-hyperlipidemic activities in STZ-induced diabetic rats. Results showed a significant decrease in blood glucose and significant increase in plasma insulin and liver glycogen levels in STZ induced diabetic rats, comparable to glibenclamide. Anti-hyperlipidemic activity was evidenced by decrease in serum TC, TG. LDL-C, VLDL-C with a significant increase in HDL-C.
• Antibacterial / Roots: Study of powdered root material from Chloris barbata yielded bioactive constituents linked to its antibacterial activity against Staphylococcus aureus and Escherichia coli.
