Hibiscus: Uses and Risk

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Hibiscus sabdariffa, commonly known as hibiscus, is a plant widely recognized for its potential health benefits and uses in traditional medicine. It is often consumed in the form of teas, extracts, and supplements. However, while hibiscus is celebrated for its beneficial properties, it is also important to consider the potential risks associated with its consumption.

Uses of Hibiscus

Antihypertensive Effects

Hibiscus has been extensively studied for its ability to lower blood pressure. Clinical trials have demonstrated that hibiscus tea can effectively reduce systolic and diastolic blood pressure in prehypertensive and mildly hypertensive adults, making it a promising natural alternative for managing hypertension5 7. The antihypertensive effects are attributed to its diuretic activity and inhibition of the angiotensin-converting enzyme (ACE)3.

Cardiovascular Benefits

Hibiscus is also noted for its positive impact on cardiovascular health. It has been shown to improve postprandial vascular function and reduce cardiometabolic risk markers, potentially lowering the risk of cardiovascular diseases2. The extract of hibiscus calyces has been found to enhance flow-mediated dilation, a measure of vascular health, and improve systemic antioxidant response2.

Metabolic and Liver Health

Hibiscus extracts have shown potential in managing obesity and related metabolic disorders. Studies indicate that hibiscus can reduce body weight, body fat, and improve liver steatosis, suggesting its role in preventing non-alcoholic fatty liver disease6. Additionally, hibiscus has been found to inhibit adipogenesis and improve insulin resistance in high-fat diet-induced obese rats10.

Risks of Hibiscus

Potential for Increased Blood Pressure

While hibiscus is generally considered beneficial for lowering blood pressure, excessive consumption may have adverse effects. In animal studies, high doses of hibiscus were associated with increased systolic blood pressure and a proinflammatory state, highlighting the importance of moderation1.

Interaction with Medications

Hibiscus may interact with certain medications, particularly those used to manage blood pressure. In a clinical trial, hibiscus was compared to lisinopril, a common antihypertensive drug, and while it showed effectiveness, the results were less pronounced than those of the medication3. This suggests that individuals on blood pressure medications should consult healthcare providers before using hibiscus supplements.

Other Considerations

Hibiscus has been shown to have protective effects against oxidative stress and toxicity induced by certain compounds, such as cypermethrin, indicating its antioxidant properties4. However, the long-term effects and safety of high-dose hibiscus consumption remain areas for further research.

Conclusion

Hibiscus sabdariffa offers a range of health benefits, particularly in managing hypertension, improving cardiovascular health, and supporting metabolic and liver functions. However, potential risks, such as increased blood pressure with excessive intake and interactions with medications, should be considered. As with any supplement, it is crucial to use hibiscus in moderation and consult healthcare professionals, especially for individuals with existing health conditions or those taking medications.
