The flower of Hibiscus rosa-sinensis is widely used for human consumption or as a spice.

For conjunctivitis:

There is no available information establishing a means of preparation and dosage other than that referred to by traditional use.

For fever, flu and cough:

Prepare a decoction or infusion with 1–2 flowers in 250 mL (1 cup) of water.

For decoction, boil for at least 3-4 minutes^2-3 in a covered pot; for infusion, add boiling water to the flowers, cover and leave to cool down. Filter and drink 1 cup 3 times a day.

According to published and other information:

Topical use for conjunctivitis is classified as REC, based on the significant traditional use (OMS/WHO)⁴ documented in the TRAMIL surveys.

In the event of conjunctivitis, there is a risk of increasing irritation further as a result of applying the leaf juice. In any application to the eye, strict hygienic measures should be observed in order to avoid contamination or additional infection. Contact with any substances that may be irritating to the conjunctiva should be avoided.

Should there be a notable worsening of the patient’s condition, or should conjunctivitis last more than 3 days, seek medical attention.

Oral use for fever, flu and cough is classified as REC, based on the significant traditional use (OMS/WHO)⁴ documented in the TRAMIL surveys.

Should there be a notable worsening of the patient’s condition, or should fever last more than 2 days, or cough persist for more than 5 days, seek medical attention.

Due to risk of abortion, not for oral use during pregnancy nor during lactation or by children under 10 years old.

TRAMIL Research¹³

The aqueous extract (30%) from the leaf, using the Draize method for eye toxicity in New Zealand rabbit, did not cause irritation.

TRAMIL Research²⁴

The crushed fresh leaf was applied topically on the skin (0.6 g plant material on an area of approximately 6 cm²) of male New Zealand rabbits. After 6 hours the compress was removed and observations made of erythema and edema after 24, 48 and 72 hours. No evidence of irritation was found and the fresh crushed leaf may therefore be categorized as non-irritant.

The hydroethanolic extract (50%) from the dried aerial parts, administered orally to male and female mice, gave an LD₅₀ = 1 g/kg¹⁵.

The alcoholic extract (70%) from the dried leaf, administered intraperitoneally to mouse, resulted in an LD₅₀ = 1.53 g/kg¹⁶.

The fraction of benzene extract from the fresh flower, which is insoluble in water and soluble in ether, when administered orally to pregnant mice (73 and 186 mg/kg), proved abortifacient¹⁹.

The benzene extract from the flower, administered orally to rats (186 mg/kg), caused abortifacient effects; while the ethanolic extract (95%), at a dose of 250 mg/animal, caused antispermatogenic effects²⁰. Other reports on the flower extract cite contraceptive activity in human adult²², antispermatogenic activity in male rat and embryotoxic properties in the fetus of rat²¹.

In a screening of 1,083 adult women, 500 received 800 mg tablets of a mix of the flower and other plants (Embelia ribes and Ferula foetida in equal proportions) 3 times/day during 6 months. No evidence of toxicity was reported²³.

There is no available information documenting the safety of medicinal use in children or women while breast feeding.

The flower contains flavonoids: apigenin, pelargonidin⁵, cyanidin, quercetin, chrysanthemin (cyanidin 3-O-glucoside); organic acids: citric, oxalic, tartaric^6-7.

The leaf contains lipids, alkanes, triterpenes: taraxerol; sterols: b-sitosterol^8-11.

Proximate analysis of 100 g of flower¹²: calories: 36; water: 89.8%; protein: 0.4%; fat: 0.4%; carbohydrate: 8.8%; fiber: 1.6%; ash: 0.6%; calcium: 4 mg; phosphorus: 27 mg; iron: 1.7 mg; thiamine: 0.03 mg; riboflavin: 0.05 mg; niacin: 0.60 mg; ascorbic acid: 4 mg.

TRAMIL Research¹³

The aqueous extract (30%) (decoction) from the leaf, using the Draize method for assessment of ocular anti-inflammatory activity in New Zealand rabbit, reduced experimentally-induced inflammation in a minor degree, as well as inflammatory injuries in cornea and iris.

TRAMIL Research²⁵

The aqueous extract (maceration) from the flower, did not show any antimicrobial activity in vitro (359 µg/mL) against Staphylococcus aureus nor Haemophilus influenzae.

The ethanolic extract (80%) from the entire dried plant did not show any antiviral activity in vitro¹⁴.

The hydroethanolic extract (50%) from the aerial parts, administered intraperitoneally to mouse (500 mg/kg), showed antipyretic activity and depressed the central nervous system, enhancing the action of barbiturics¹⁵.

The ethanolic extract (70%) from the dried leaf, administered intraperitoneally to rats (100 mg/kg), displayed antipyretic and anti-inflammatory activity. When administered orally (125 mg/kg) to mouse analgesic activity was indicated¹⁶.

The hydroethanolic extract (50%) from the aerial parts, administered intravenously to dog (50 mg/kg), exhibited hypotensive activity¹⁵.

Several reports indicate the anti-estrogen properties of the flower^17-18.
