- Dosing considerations for Hibiscus.
Hibiscus is used for treating loss of appetite, colds, heart and nerve diseases, upper respiratory tract pain and swelling (inflammation), fluid retention, stomach irritation, and disorders of circulation; for dissolving phlegm; as a gentle laxative; and as a diuretic to increase urine output.
In foods and beverages, hibiscus is used as a flavoring. It is also used to improve the odor, flavor, or appearance of tea mixtures.
Possibly Effective for...
- High blood pressure. Some early research shows that drinking hibiscus tea for 2-6 weeks decreases blood pressure in people with mildly high blood pressure. Other early research shows that taking a hibiscus extract by mouth for 4 weeks may be as effective as the prescription drug captopril for reducing blood pressure in people with mild to moderate high blood pressure. However, an analysis of results from various clinical studies suggests that there is not enough evidence to draw strong conclusions about the effects of hibiscus in reducing high blood pressure.
Insufficient Evidence to Rate Effectiveness for...
- High cholesterol. Some early research suggests that taking hibiscus extract by mouth or consuming hibiscus tea might lower cholesterol levels in people with metabolic syndrome or diabetes. However other early research shows that taking a specific extract of hibiscus leaves (Green Chem, Bangalore, India) for 90 days does not improve cholesterol levels in people with high cholesterol. Also, taking hibiscus extract by mouth for 12 weeks does not appear to reduce cholesterol compared to the drug pravastatin and may actually increase cholesterol levels in people with high cholesterol.
