Pugo-pugo is an annual herb with slender stems, 10
to 50 centimeters high, usually scattered, rising from slender creeping rootstocks. Leaves are narrow, 3 to 10 centimeters long and less than 3 millimeters wide;
shining green. Spikes are mostly solitary, ovoid, green to white,
8 millimeters long or less. Spikelets very numerous, lanceolate,
about 3 millimeters long, with the keel of the flowering glume not winged. Whole inflorescence is subtended by 3 long
leafy bracts. Fruit is a nut, about 1 millimeters long and compressed.
- Throughout the Philippines,
at low to medium altitudes, especially in open grasslands, waste places,
along dikes, rice paddies and other moist places, at low and medium altitudes.
Study for essential oil from underground parts yielded 23 components, the main components of which were manoyl oxide (44.08%), ß-pinene (13.58%), cyperene (7.63%), and y-terpineol (7.37%). (11)
- Study of leaf essential oil yielded 33 compounds accounting for 96.1% of the oil composition. Major essential oil constituents were α-cadinol (40.3 %), τ-muurolol (19.5 %), and germacrene D-4-ol (12.5 %) with smaller amounts of δ-cadinene (2.9 %), and germacrene D (4.0 %). (13)
Kyllinga leaves are glossier than turfgrass leaves. Also, they have a distinctive
"minty sweet" scent when leaves are mowed or crushed.

- Studies have shown antioxidant, antiviral, anxiolytic, CNS depressant, hepatoprotective, anti-aggressive properties.
· In Paraguay folk medicine, rhizomes used as a refreshing drink.
· Colds with fever; when taken internally, has a perspiring (sudorific)
· Whooping cough, bronchitis, swelling pain in the throat, malaria.
· Snake bites, furuncles, sprains: Apply poultice of pounded
· Skin pruritus: Decoction may be used as an external wash.
· In India, used for dysentery - ten fresh tubers made into paste and consumed with rice; once daily for three days.
· Used for liver disease.
· Malays used the rhizome for poulticing sore legs. Leaves used for diarrhea. For treating scurf, pounded roots applied to affected area. (10)
· In Paraguay folk medicine, used as digestive, diuretic, sedative, tonic, antispasmodic, and sudorific.
• CNS Depressant Activity / Sedative Effect: Study of crude hydro-alcoholic rhizome extract of Kyllinga brevifolia on mice showed increase gastrointestinal transit, decrease spontaneous locomotor activity, piloerection, passitivity, catatonia and stereotyped behavior. It also showed a significant dose-dependent increase in hypnotic effect induced by pento-barbital. Results explain it traditional use to alleviate stress and as a sedative agent. (1)
• Flavonoids / Antiviral: Study yielded two known flavonoids glycosides and a new quercetin. triglycoside, a compound that showed moderate antiviral activity.
• Anxiolytic / Sedative / Rhizomes: Study evaluated the putative sedative, anxiolytic effects of crude hydro-alcoholic extract and fractions of rhizomes of K. brevifolia in male male using open filed, hole board, rota-rod, and elevated plus maze (EPM) test. Results showed a weak sedative and interesting anxiolytic-like effect in mice and suggests a potential for use in the treatment of anxiety in humans. (5)
• Hepatoprotective: Study evaluated a methanolic extract of whole plant of K. brevifolia in male Wistar albino rats showed significant protection against CCl4-induced hepatocellular injury. (7)
• Anti-Aggressive Activity / Rhizomes: Study evaluated the anti-aggressive activity of hydroethanolic extract of rhizomes and various fractions on aggressive behavior in isolated-induced aggression model in male mice. Results showed a general anti-offensive aggressive activity and suggests a potential in the treatment of reactive aggression in humans. (9)
• Antioxidant: In an in vitro study of 31 medicinal wetland plants in Taiwan, Kylinga brevifolia was one of seven that showed high antioxidant activity and high total polyphenolic contents. (12)
