Cardioprotective effect of the Hibiscus rosa sinensis flowers in an oxidative stress model of myocardial ischemic reperfusion injury in rat.
Background: The present study investigates the cardioprotective effects of Hibiscus rosa sinensis in myocardial ischemic reperfusion injury, particularly in terms of its antioxidant effects.
Methods: The medicinal values of the flowers of Hibiscus rosa sinensis (Chinese rose) have been mentioned in ancient literature as useful in disorders of the heart. Dried pulverized flower of Hibiscus rosa sinensis was administered orally to Wistar albino rats (150–200 gms) in three different doses [125, 250 and 500 mg/kg in 2% carboxy methyl cellulose (CMC)], 6 days per week for 4 weeks. Thereafter, rats were sacrificed; either for the determination of baseline changes in cardiac endogenous antioxidants [superoxide dismutase, reduced glutathione and catalase] or the hearts were subjected to isoproterenol induced myocardial necrosis.
Results: There was significant increase in the baseline contents of thiobarbituric acid reactive substances (TBARS) [a measure of lipid per oxidation] with both doses of Hibiscus Rosa sinensis. In the 250 mg/kg treated group, there was significant increase in superoxide dismutase, reduced glutathione, and catalase levels but not in the 125 and 500 mg/kg treated groups. Significant rise in myocardial thiobarbituric acid reactive substances and loss of superoxide dismutase, catalase and reduced glutathione (suggestive of increased oxidative stress) occurred in the vehicle treated hearts subjected to in vivo myocardial ischemic reperfusion injury.
Conclusion: It may be concluded that flower of Hibiscus rosa sinensis (250 mg/kg) augments endogenous antioxidant compounds of rat heart and also prevents the myocardium from isoproterenol induced myocardial injury.

A study undertaken to explore the antifertility and estrogenic activity of ethanolic extract of
the roots of Hibiscus rosa-sinensis Linn, lead to a strong anti-implantation (inhibition 100%) and uterotropic activity at the dose level of 400 mg/kg body weight leading to anticonceptive effect.

Thanks a lot Debby for the new Title "The Flower Man". I will have to work harder to save my title.

A 2008 USDA study shows consuming hibiscus tea lowers blood pressure in a group of pre-hypertensive and mildly hypertensive adults. Three cups of tea daily resulted in an average drop of 7.2 point in their systolic blood pressure, compared to a 1.3 point drop in the volunteers who drank the placebo beverage. Study participants with higher blood pressure readings (129 or above), had a greater response to hibiscus tea, their systolic blood pressure went down by 13.2 points. This data supports the idea that drinking hibiscus tea in an amount readily incorporated into the diet may play a role in controlling blood pressure, although more research is required.

From now on I'm calling Dr Dushyant, "The Flower Man" because of all these incredible photos and background information on flowers.
