Labuag3Botany

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.

Properties
– Rich in mucilage.
– Considered emollient, febrifuge, laxative, abortifacient.

Parts used
Leaves, stems and roots.

Uses
Edibility / Culinary
– Acid leaves used for salads or as a pot-herb.
– In India, fruit used in curries.

Folkloric
– In Senegal, plant used as an emollient.
– Leaves used for cough.
– Zulus use a lotion or ointment of the stem and leaf as treatment for penile irritation; including venereal sores and urethritis. Infusion used as injection into the urethra and vagina for gonorrhea and other urethral inflammations.
– Decoction of leaves or roots used for skin complaints.
– In other traditional systems, used for paralysis, epilepsy, convulsions, pregnancy; as abortifacient.
– Leaf, root and fruit juice used for cutaneous parasitic infections.
– Roots used as febrifuge, laxative; for tumors and cancers.
– In Nigeria, leaf and fruit juice given to children for cough.
– In India, among the folklore herbalists and Tripuri medical practitioners, curry is made from its tender leaves and given to patients with jaundice.

Others
– Plant yields a fiber of good quality.
– In Brazil, used as a substitute for jute.
– Provides material for roof thatching.

Study Findings
• 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.
• 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.
