Piñgot is a plant that usually forms circular, dense, matted tufts of finely striate stems, 30 to 90 centimeters high, soft and pithy. Base of the stalk is surrounded by short, sheathing leaves. Inflorescence is very variable, lax and pendulous, with slender branches and distant flowers, or globose and sessile with densely packed flowers. Sepals are lanceolate, exceeding the length of the obovoid brownish capsules. Seeds are minute, yellow, and very obtuse at each end.


– In open, swampy places at all altitudes from 1,400 to 2,300 meters in Luzon (Benguet, Bontoc Subprovinces).
– Also occurs in warmer parts of both hemispheres, especially common in the north temperate zone.

– Stems yield araban and xylan.
– Study isolated 13 compounds from the medullae – juncusyl ester A and B, 5-a spinasterol, B-sitosterol, effusol, p-coumaric acid, nobiletin, quercetin, rutinose, among others.
– Study isolated a new cycloartanelactone glucoside, Juncoside I.
– Dry stems yielded six phenolic constituents: 7-carboxy-2-hydroxy-1-methyl-5-vinyl-9, 10-dihydrophenanthrene, 2,3-isopylidene-1-O-ferulic acid glyceride, (2S)-2, 3-isopylidene-1-0-p-coumaroyl glycer- ide, dehydroeffusal, p-hydroxybenzaldehyde and luteolin- 5,3′-dimethyl ether.

Traditionally considered antilithic, antiphlogistic, depurative, diuretic, descutient, febrifuge, pectoral and sedative.

Parts used


– Pith is used for keeping open fistulous sores.
– Malays used the pith for urinary troubles.
– Decoction used as antilithic, pectoral and descutient.
– In traditional Chinese medicine, used for painful urination, insomnia and sleep restlessness, sore throat, and ulcerations of the mouth and tongue. Used to eliminate excessive “heart-qi” and induce urination.
– Cherokees use the herb as an herbal constituent in emetic preparations; also, used as cathartic.
– In China and Japan, folk medicine for fever, insomnia, eclampsia, and fever sores.
– Charred juncus used as sedative.

• Basketry / Weaving: Stem piths used for basketry, weaving mats, and for making lamp wicks. Dried stems used for making rope.
• Paper: Fiber from stems used for making paper.


Study Findings
• Phenolic Contents: Ethanolic extract of the dry stem of J effusus yielded six phenolic constituents. Compounds 5 and 6, p-hydroxybenzaldehyde and luteolin-5-3′-dimethyl ester were reported for the first time.
• Effusenone A / Phenolic Compounds: Study yielded a novel diterpene, effusenone A, and three novel phenolic compounds from the stem of J. effusus.
• Dihydrodibenzoxepin / Cytotoxicity: Study isolated a novel dihydrodibenzoxepin and preliminary bine shrimp lethality assay showed it to be cytotoxic.
• Sedative / Hypnotic Effect: Study of extracts of JE showed influences on autonomic activity and sleeping time with pentobarbital sodium. The ethyl acetate extract showed to be the effective sedative and hypnotic fraction.
• Dehydroeffusol / Anxiolytic / Sedative: Study isolated a novel phenanthrene chemical, dehydroeffusol, which showed anxiolytic and sedative properties.
• Chemical Constituents / Antibacterial: Study isolated 30 compounds, six of which were new. Compound 6 (dehydroeffusol) showed antibacterial activity, with good inhibitory effect on four gram positive bacteria and Candida albicans.
