Distribution
- Most islands and provinces throughout the Philippines in open grasslands, at low and medium altitudes.
- Certainly introduced.
- Also occurs in tropical Africa, Asia, and Malaya.

Constituents
- Seeds yield: oil, 13-17%, with a predominance of linoleic acid in the fatty acid component of the oil, followed by palmitic and oleic acids, and small concentrations of malvalic acid, sterculic, dihydrosterculic and epoxy acids.
- Essential oil from leaves was dominated b y monoterpenes (34.1%) and sesquiterpene compounds (41.2%). Major oil constituents were ß-caryophyllene (12.9%), menthol (10.6%), methyl salicylate (9.7%), and camphor (9.2%), with significant amounts of germacrene D (5.5%), hexadecanoic acid (4.3%) α-humulene (4.0%), 1,8-cineole (3.0%) and methone (3.0%).

Properties
- Rich in mucilage.
- Considered emollient,
febrifuge, laxative, abortifacient, pectoral, cardiotonic.

Parts used
Leaves, stems, fruit, flowers, and roots.

Others
- Plant yields a fiber of good quality.

Studies
Fatty Acid Composition: In a study of the fatty acid composition of seed oils of seven Hibiscus species of malvaceae, all contained 13-17% oil. Linoleic acid predominated in the component fatty acids of all oils, followed by palmitic acid and oleic acid. (1)
Biodiesel Source: Study investigated the viability of using locally available vegetable seed oils to produce biodiesel. Two indigenous seeds - Hibiscus surattensis and Hibiscus sabdariffa were used in the study. Results suggest H. sabdariffa blend of 40:60 and H. surattensis blend of 30:70 can be recommended for use in diesel engines without any engine modifications. (6)

Availability
Wild-crafted.
