About 300 species are found worldwide. Its beauty makes it one of the most widely cultivated of flowers, in brilliant hues of red, orange, or purplish-reds, with short-lived but continuing blooms. The red flowered variety has been preferred in medicine.
Gumamela is an erect, much-branched, glabrous shrub, 1 to 4 meters high. Leaves are glossy green, ovate, acuminate, pointed, coarsely-toothed, 7 to 12 centimeters long, alternate, stipulate. Flowers are solitary, axillary, very large, about 10 centimeters long, and 12 centimeters in diameter. Outermost series of bracteoles are 6, lanceolate, green, and 8 millimeters long or less. Calyx is green, about 2 centimeters long, with ovate lobes. Petals are red, orange or rose-white, obovate, entire, rounded tip, and imbricate. Stamens form a long staminal tube enclosing the entire style of the pistil and protruding out of the corolla. Ovary is 5-celled, styles are 5, fused below. Fruits are capsules, loculicidally 5-valved, but rarely formed in cultivation.

• Biologic Activities: Studies have demonstrated anti-bacterial, hypotensive, antispasmodic, and chemopreventive activities. It has shown glucose lowering in diabetic rats. Leaf extract has shown to promote hair growth.
• Post-Coital Antifertility Activity / Roots: The study explored the antifertility and estrogenic activity of root extracts of H. rosa-sinensis. A strong anti-implantation and uterotropic activity was observed.
• Post-Coital Antifertility Activity / Flowers: Study of different extracts on the postcoital antifertility properties showed only the flower extracts were 100% effective in preventing pregnancy. Extracts from H mutabilis, H schizopetalus and M grandiflorus did not markedly affect pregnancy.
• Wound Healing Activity: Results on flower extracts study suggest H. rosa-sinensis aids wound healing in the rat model. Study on wound healing showed an ethanolic extract of flowers to have greater wound healing activity than the nitrofurazone ointment. The extract treated wound showed much faster healing as indicated by improved rates of epithelization and wound contraction.
• Cardioprotective: Study evaluated the cardioprotective effect of the Hibiscus rosa sinensis flowers in an oxidative stress model of myocardial ischemic reperfusion injury in rat: The study concludes that the flower of Hibiscus rosa-sinensis augments endogenous antioxidant activity and prevented isoproterenol induced myocardial injury.
• Spasmogenic / Spasmolytic Constituents: Presence of cholinergic and calcium channel blocking activities explains the traditional use of Hibiscus rosa-sinensis in constipation and diarrhoea: Study indicates the crude extract had spasmogenic and spasmolytic constituents to explain its traditional use in constipation and diarrhea.
• Phytochemical / Hypotensive Activity: Flowers extract studies isolated four new phytoconstituents. The hydroalcoholic extract showed the most significant hypotensive activity.
• Hypoglycemic / Hypolipidemic Activity / Flowers: Study of ethanol flower extract on lipids and blood glucose of STZ-induced diabetic rats showed a lipid lowering effect (decrease cholesterol and serum triglycerides with increase in HDL) and diminution in blood glucose comparable to that of glibenclamide but through a mechanism other than insulin release.
• Hypolipidemic Activity / Roots: Study showed a hypolipidemic effect compared to the standard drug guggulipid. Histopath findings in rat liver supported the role of H rosa sinensis root extract in preventing cholesterol HFD-induced hepatic steatosis.
• Antitumor / Anticancer: Study to investigate the ameliorative potential of H rosa sinensis extract in mice skin showed the extract of HRS exerts a protective effect against tumor promotion stage of cancer development.
• Cytotoxicity: Studies have showed H. rosa-sinensis flower decoction has cytotoxic properties in plant test systems. Decoction of flowers was toxic on root output and length in A. cepa and reduced the mitotic index significantly. Results suggest that H. rosa-sinensis flowers contain antimitotic constituents which stop cell division in anywhere of the cell cycle.
• Excipient Potential: Study concludes that a novel hydrophilic excipient, a mucilage extracted from H rosa sinensis can be used in the development of sustained-release tablets.
• Gentisic Acid / Tumor Inhibition / Anti-Carcinogenesis: Study evaluated the role of gentisic acid, a chemical constituent of H. rosa-sinensis, on DBMA/croton-oil-mediated carcinogenesis in mouse skin. Results suggest the gentisic acid plays a role in the modulatory activity of H. rosa-sinensis extract.
• Antianxiety / CNS Effect: Study showed statistically significant decrease in exploratory behavior, latency, and increased rearing and ambulatory behavior. Results suggest H. rosa-sinensis has significant anti-anxiety associated psychobehaviour modulation.
• Analgesic: Study of alcohol and aqueous extracts of dried leaves showed marked dose-dependent analgesic activity.
• Blood Pressure Lowering: Study showed drinking of hibiscus tea lowered blood pressure in a group of pre-hypertensive and mildly hypertensive adults.
• Hair-Growth Potential: Petroleum ether extract of leaves and flowers of HRS were studied for hair growth potential over shaved skin of albino rats. Results showed the leaf extracts to exhibit more potency on hair growth.
• Antibacterial / Leaves and Flowers: Study evaluated extracts of leaves and flowers against clinical isolates of bacteria. Staphylococcus aureus was most sensitive to extracts of flowers. Flower extracts had stronger antibacterial effects than leaves.
• Spermatogenesis Effect / Flowers: Study evaluated the effect of crude extract of flowers as antifertility agent on male albino rats. Results showed changes in the germinal epithelium of the testes from mild damage to near total sloughing, and suggests a potential role as an anti-fertility agent.
• Effect on Androgenic Alopecia / Leaves: Study showed an ethanolic extract of leaves to possess significant anti-androgenic alopecia activity and is comparable to standard FDA approved drug for androgenic alopecia finasteride.
• Antinociceptive / Anti-Inflammatory / Leaves: Study of a methanol extract of leaves showed dose-dependent peripheral analgesic activity in the acetic acid-induced writhing response and tail flick method. A carrageenan and dextran induced paw edema models using indomethacin as standard showed significant anti-inflammatory activity.
• Anti-Ulcer / Roots: Study evaluated various extracts of roots of H. rosa sinensis in pyloric ligation induced gastric ulcer in albino rats for antiulcer activity. An aqueous extract of roots showed highly significant dose-dependent antiulcer activity.
• Lack of Genotoxicity: Evaluation of a methanol extract of flowers showed no genotoxicity in the micronucleus assay in Balb/c mice. The lack of in vivo genotoxic activity provides potential for the flower extract to be used as a pharmaceutical material.
• Fibrinolytic Activity: The fibrinolytic system’s main function is to dissolve clots in circulation. The inactive precursor plasminogen is converted into plasmin by a plasminogen activator (tPA). An aqueous extract of H. rosa sinensis exhibited significant fibrinolytic activity.
• Antihyperlipidemic / Leaves: A methanol extract of leaves was evaluated for antihyperlipidemic activity against Triton induced hyperlipidemia in mice. Simvastatin was used as reference drug. Results showed a significant decrease in total cholesterol (71%), triglyceride (74%) and LDL (91%).
• Anthelmintic / Flowers: Study showed the anthelmintic activity of aqueous and ethanolic extract of flowers against Indian earthworm Pheretima posthuma. Standard references were Piperazine citrate, Albendazole, and Pyrantel pamoate.
• Cardioprotection: Study investigated the cardioprotective effects of Hemidesmus indicus and Hibiscus rosa-sinensis in ischemia reperfusion injury in isolated rat hearts. Both drugs dose-dependently reduced ectopic beats and duration of ventricular tachycardia. HRS significantly reduced infarct size at all concentrations in a dose-dependent manner. At higher doses, HRS can cause vasodilation, positive inotropic effect and cardioprotection.
