What is Hibiscus Sabdariffa Extract?
Hibiscus Sabdariffa Extract (Hs, roselle; Malvaceae) has been used traditionally as a food, in herbal drinks, in hot and cold beverages, as a flavouring agent in the food industry and as a herbal medicine. In vitro and in vivo studies as well as some clinical trials provide some evidence mostly for phytochemically poorly characterised Hs extracts.
Organic hibiscus extract showed antibacterial, anti-oxidant, nephro- and hepato-protective, renal/diuretic effect, effects on lipid metabolism (anti-cholesterol), anti-diabetic and anti-hypertensive effects among others. This might be linked to strong antioxidant activities, inhibition of α-glucosidase and α-amylase, inhibition of angiotensin-converting enzymes (ACE), and direct vaso-relaxant effect or calcium channel modulation. Phenolic acids (esp. protocatechuic acid), organic acid (hydroxycitric acid and hibiscus acid) and anthocyanins (delphinidin-3-sambubioside and cyanidin-3-sambubioside) are likely to contribute to the reported effects.

Hibiscus Sabdariffa Extract Benefits:
1.Lower Blood Pressure
High blood pressure increases your risk of heart disease. Some studies show that drinking hibiscus sabdariffa extract may help reduce systolic blood pressure levels compared to a placebo.
Other studies show that it may help to reduce both systolic and diastolic blood pressure.
2.Reduce Cholesterol Levels
Some studies show that organic hibiscus extract may reduce cholesterol levels — another risk factor of heart disease. In one study, people who drank hibiscus tea experienced an increase in “good cholesterol” (high-density lipoproteins) and a decrease in “bad cholesterol” (low-density lipoproteins). Many of the current studies have been limited to individuals with certain conditions, however, and some show conflicting results.
3.Improve Liver Health
Organic hibiscus extract may help to improve liver health. A study using hamsters showed that hibiscus tea may help decrease markers of liver damage.One study with human participants showed that hibiscus extract may improve liver steatosis, which could reduce the risk of liver failure.
Along with anthocyanins, hibiscus sabdariffa extract also contains another antioxidant called polyphenols, which have been shown to have anti-cancer properties. Much of the current research involves test-tube studies.One study showed that hibiscus extract limits cell growth and reduces the invasiveness of mouth cancer.Other test-tube studies show that hibiscus tea may help prevent the spread of prostate cancer cells and stomach cancer cells.
Hibiscus tea may provide antibacterial properties. Again, the current research is limited to test-tube studies. One showed that hibiscus extract inhibits E. coli.It may also be just as effective as some medications at fighting many different bacteria strains.
6.Promote Weight Loss
Several studies show the potential of hibiscus tea to promote weight loss and prevent obesity. One study showed that hibiscus extract reduced body weight, body fat, and body mass index after 12 weeks.
