The bioactive compounds in hibiscus, such as polyphenols and flavonoids, play a crucial role in inhibiting adipogenesis, reducing lipid accumulation, and improving metabolic profiles by down regulating adipogenic transcription factors and enhancing lipid metabolism. Additionally, hibiscus has been found to modulate adipokine levels, decrease visceral fat, and improve glycemic profiles, further supporting its anti-obesity effects. These findings suggest that hibiscus could be an effective natural adjuvant for preventing and managing obesity and its associated comorbidities.
What Research Says?
- Many studies show that Hibiscus sabdariffa extracts (HSE) can greatly lower body weight and fat. One study with people having a BMI of 27 or more found that taking HSE for 12 weeks made them lose weight and fat, and their waist sizes got smaller compared to their hips. Also, HSE helped make liver conditions better and lowered the amount of free fatty acids in the blood without any bad side effects. Another research on mice that ate a lot of fat showed that HSE stopped them from gaining too much weight, helped control blood sugar levels, and kept cholesterol levels normal.
- Studies show that hibiscus can affect hunger signals. In a study with people who were overweight, a mix of hibiscus and lemon verbena made body measurements better, lowered blood pressure, and boosted health. The research found more hormones that reduce hunger (like glucagon-like peptide-1) and fewer that increase hunger (like ghrelin), which may help control appetite.
- Hibiscus extracts can help manage fat in the body. Delphinidin-3-sambubioside (Dp3-Sam), a colorant from the Hibiscus plant, was found to lower weight gain, belly fat, and liver fat in rats fed a high-fat diet. It also reduced fat levels inside liver cells, showing it could improve fat metabolism problems. Another study showed that Hibiscus extract could stop fat build-up and block fat cell formation by affecting certain pathways and control factors.
- Hibiscus sabdariffa has properties that fight inflammation and protect cells, which help prevent obesity. The active parts of the plant can lower the levels of substances in the body that cause inflammation. They also help keep the gut healthy by boosting mucin production and proteins that protect the gut lining. Also, when mixed with lemon verbena, hibiscus extracts can decrease factors linked to inflammation like TNF-α and IL-6. At the same time, they increase the activity of genes that cause the body to produce heat.
2. Lowers Blood Pressure
Hibiscus has been shown to effectively lower blood pressure in both prehypertensive and mildly hypertensive individuals. The antihypertensive effects of hibiscus are attributed to several mechanisms, including its antioxidant properties, which reduce oxidative stress and inflammation, and its ability to promote vasodilation by increasing nitric oxide production, thereby relaxing and widening blood vessels. Additionally, hibiscus has mild diuretic properties that help reduce blood volume, further contributing to lower blood pressure. Clinical trials and meta-analyses have consistently demonstrated significant reductions in both systolic and diastolic blood pressure among those who consume hibiscus tea regularly, with some studies noting effects comparable to those of standard antihypertensive medications.
What Research Says?
- Many studies show that hibiscus can lower blood pressure. One study with 65 adults who had early or mild high blood pressure found that drinking hibiscus tea every day lowered their top blood pressure number by 7.2 mm Hg more than a fake treatment. Also, a review of many studies showed that hibiscus helps to reduce both the top and bottom blood pressure numbers.
- Hibiscus can help lower blood pressure because it has a lot of organic acids, polyphenols, anthocyanins, and other helpful compounds. These parts work as antioxidants, reduce swelling, and increase urine production. Together, they help bring down blood pressure. Hibiscus can block an enzyme called ACE that is important for controlling blood pressure. It also helps the health of the blood vessels.
- Clinical trials have compared hibiscus to usual blood pressure medicines.

For instance, a meta-analysis revealed that Hibiscus sabdariffa supplementation reduced total cholesterol by an average of 14.66 mg/dL and LDL cholesterol by 9.46 mg/dL. Additionally, clinical trials have indicated that hibiscus tea consumption can lead to a notable decrease in LDL cholesterol and triglycerides, with some studies also reporting an increase in HDL cholesterol.
What Research Says?
- Many studies looked at how Hibiscus sabdariffa affects cholesterol. One big review of nine trials with 503 people showed that taking Hibiscus sabdariffa made total cholesterol go down a lot compared to others who didn’t take it (WMD = -14.66; 95% CI [-18.22, -11.10]; p = .000). Also, a study with 42 people found that after four weeks of taking Hibiscus sabdariffa extract (HSE), their cholesterol levels dropped by 8.3% to 14.4%.
- Lowering LDL-C, or “bad cholesterol,” is important for heart health. The same study also found a big drop in LDL-C levels (WMD = -9.46; 95% CI [-14.93, -3.99]; p = .001). Also, rabbits on a high-cholesterol diet with Hibiscus sabdariffa extract had lower LDL-C and less atherosclerosis.
- High-density lipoprotein cholesterol (HDL-C), or “good cholesterol,” is key. Studies on the effect of Hibiscus sabdariffa on HDL-C show different results. Some studies saw no big changes in HDL-C. But others found that HDL-C levels went up in people with metabolic syndrome.
- The health benefits of Hibiscus sabdariffa come from its high levels of anthocyanins and polyphenols. These substances act as antioxidants. They help stop LDL-C, the “bad” cholesterol, from oxidizing. This can lower the risk of atherosclerosis, which is when arteries harden. Also, the polyphenols in Hibiscus sabdariffa can turn on AMPK and lower SREBP-1. This means the body makes fewer fatty acids and gets better at removing fats from the liver.
9. Supports Liver Health
Hibiscus has been shown to support liver health through its potent antioxidant and anti-inflammatory properties. Hibiscus extract can reduce liver damage and improve conditions such as hepatic steatosis (fatty liver disease) by decreasing lipid accumulation, inflammation, and oxidative stress in the liver. Hibiscus extract can lower markers of liver damage and enhance liver function by modulating key signaling pathways like IRS-1/Akt and NRF2. Additionally, hibiscus has been found to protect the liver from various toxins and improve liver enzyme levels, which are critical for maintaining overall liver health.
What Research Says?
- A study showed that Hibiscus sabdariffa extract (HSE) helped obese people lose weight and body fat. It also made their livers healthier. The good results came from polyphenols in HSE. These reduced harmful fats in the blood and improved liver health without causing harm.
- Many animal studies support the liver-protecting effects of Hibiscus extracts. For instance, HSE helped guard against liver fibrosis in rats. It did this by lowering oxidative stress and stopping liver cells from activating. Another study showed that Hibiscus extracts lessened liver damage in mice caused by acetaminophen. They reduced oxidative stress and cell death.
