Overview InformationHibiscus is a plant. The flowers and other parts of the plant are used to make medicine.
People use hibiscus for conditions such as high blood pressure, high cholesterol, increasing the production of breast milk, infections, and many other conditions, but there is no good scientific evidence to support most of these uses.
How does it work?The fruit acids in hibiscus may work like a laxative. Some researchers think that other chemicals in hibiscus might be able to lower blood pressure; reduce levels of sugar and fats in the blood; decrease spasms in the stomach, intestines, and uterus; reduce swelling; and work like antibiotics to kill bacteria and worms.
Uses & Effectiveness
Possibly Effective for
- High blood pressure. Most early research shows that drinking hibiscus tea for 2-6 weeks decreases blood pressure by a small amount in people with normal or slightly high blood pressure. Some early research shows that drinking hibiscus tea might be as effective as the prescription drugscaptopril and more effective than the drug hydrochlorothiazide for reducing blood pressure in people with slightly high blood pressure.
Insufficient Evidence for
- Abnormal cholesterol levels. Some early research shows that drinking hibiscus tea or taking hibiscus extract by mouth can lower levels of cholesterol and other blood fats in people with metabolic disorders such as diabetes. However, other research shows that hibiscus does not improve cholesterol levels in people with high cholesterol.
- Bladder infections (urinary tract infections). Early research has found that people with urinary catheters living in long-term care facilities who drink hibiscus tea have a 36% lower chance of having a urinary tract infection compared to those not drinking tea.
- Weight loss. Early research shows that taking a product containing lemon verbena and hibiscus might help overweight and obese women feel less hungry and lose weight.
- Fluid retention.
- Heart disease.
- Irritated stomach.
- Loss of appetite.
- Nerve disease.
- Other conditions.
Side Effects & SafetyHibiscus is LIKELY SAFE for most people in when consumed in food amounts. It is POSSIBLY SAFE when taken by mouth appropriately in medicinal amounts. The possible side effects of hibiscus are not known.
Special Precautions & Warnings:Pregnancy and breast-feeding: Hibiscus is POSSIBLY UNSAFE when taken by mouth as a medicine. Side effects of hibiscus are uncommon but might include temporary stomach upset or pain, gas, constipation, nausea, painful urination, headache, ringing in the ears, or shakiness.
Diabetes: Hibiscus might decrease blood sugar levels. The dose of your diabetes medications might need to be adjusted by your healthcare provider.
Low blood pressure: Hibiscus might lower blood pressure. In theory, taking hibiscus might make blood pressure become too low in people with low blood pressure.
Surgery: Hibiscus might affect blood sugar levels, making blood sugar control difficult during and after surgery. Stop using hibiscus at least 2 weeks before a scheduled surgery.
Be watchful with this combination
Acetaminophen (Tylenol, others) interacts with HIBISCUS
Drinking a hibiscus beverage before taking acetaminophen might increase how fast your body gets rid of acetaminophen. But more information is needed to know if this is a big concern.
The following doses have been studied in scientific research:
- For high blood pressure: Hibiscus tea made by adding 1.25-10 grams or 150 mg/kg of hibiscus to 150 mL to 500 mL of boiling water has been used. The tea is steeped for 10-30 minutes and taken one to three times daily for 2-6 weeks.
