Health Benefits Hibiscus Tea
Now that we have seen most parts of the world consume the Hibiscus Tea or some edited form of it, what makes it so special?
You cannot ignore what the whole world enjoys and includes in celebrations, but it is important to understand what makes it so much consumable?
So let us have a look at its health benefits!
Preliminary studies show that drinking hibiscus tea might lower blood pressure in persons with type 2 diabetes, prehypertension, and mild hypertension. However, there is no solidly reliable evidence to support hibiscus tea in treatment for primary hypertension.
The average blood pressure of diabetics drinking hibiscus tea decreased from 134.8 mmHg (17.97 kPa) at the start of one study to 112.7 mmHg (15.03 kPa) at the end, spanning one month.
Drinking 3 cups of hibiscus tea a day for six weeks reduced blood pressure by 7 mm of Hg in participants, those who were prehypertensive and mildly hypertensive. In those persons with mean blood pressure over 129 mm Hg, the observed reduction was nearly 14 mm Hg.
Hibiscus flowers contain anthocyanins, which are believed active antihypertensive compounds, which act as angiotensin-converting enzyme(ACE) inhibitors.
The effect of drinking hibiscus tea can be compared to blood-pressure medication. According to a study published in 2007, Hibiscus sabdariffa L. can be compared to the drug lisinopril on people suffering from hypertension.
Hibiscus seemed to “decrease blood pressure (BP) from 146.48/97.77 to 129.89/85.96 mm of Hg, making it reach an absolute reduction of 17.14/11.97 mmHg (11.58/12.21%, p < 0.05).”
Reduction in blood pressure and therapeutic effectiveness proved to be lower than those obtained with lisinopril (p < 0.05). It was thus concluded that hibiscus “exerted significant antihypertensive effectiveness with a wide margin of tolerability and safety, while also significantly reducing plasma ACE activity and demonstrating a tendency to reduce the serum sodium (Na) concentrations, not modifying potassium (K) levels in the process.”
The blood pressure reducing the effect of hibiscus was attributed to its diuretic effect and its ability to inhibit the angiotensin-converting enzyme having the presence of anthocyanins.
A 2004 study compared its effectiveness to the ACE-inhibiting drug captopril. It was found that the hibiscus worked similar to the drug captopril: “obtained data confirm that H. sabdariffa extract, standardized on 9.6 milligrams of total anthocyanins, and captopril 50 mg/day, didn’t show significant differences to the relative hypotensive effect, antihypertensive effect, and tolerability.
Hibiscus, in any form, also the hibiscus tea is possibly effective for:
1.High Blood Pressure
Some research showed that drinking the tea for 2-6 weeks helps decrease blood pressure in people having mildly high blood pressure.
Other researchers show that taking a hibiscus extract in oral form for four weeks might be as effective as the prescription drug captopril for reducing blood pressure ranging from mild to moderate high blood pressure.
However, analyses of results from various clinical studies suggest that there is not enough evidence to provide a strong conclusion about effects of hibiscus in reducing high blood pressure.
Possibly effective for High BP, but you may use it even for the following though there is insufficient evidence:
2. High Cholesterol
Some researchers suggest that taking hibiscus extract orally or consuming hibiscus tea may lower cholesterol levels in those having metabolic syndrome or diabetes.
However, other research showed that taking a specific extract of hibiscus leaves for 90 days did not improve cholesterol levels in those with high cholesterol.
Also, taking hibiscus extract in oral form for 12 weeks apparently did not reduce cholesterol compared to drug pravastatin and may increase cholesterol levels in those having high cholesterol.
It Is Known To Be Useful In The Following Condition
- Loss Of Appetite
- Irritated Stomach
- Fluid Retention
- Nerve Disease
- Heart Disease
- Several Other Conditions
But be warned before using it for these uses, as more evidence is needed to rate it positive for these uses.

6. Drug Interaction Risk
Hibiscus is bound to interact with some medications. It has anticancer effects if taken with other anticancer agents and an additive effect if taken with antiviral agents.
It decreases the antimalarial efficacy of drugs and alters some inflammatory agents processed by the body such as acetaminophen.
