Health benefits of Hibiscus tea
1. Hibiscus tea controls hypertension
Hypertension is one of the main leading health problems in today’s world. According to a report, about 20% of the population expected to have hypertension in their life (2). Hypertension leads to heart-related problems, kidney and central nervous system damage, and stroke. Hibiscus extracts act as a vasodilator and control blood pressure. Therefore consumption of this tea for those who have hypertension problems (not with severe ones) helps in relaxing the vessels and lowers the pressure.
2. Lowers cholesterol level
Studies were done on the human with metabolic syndrome and type-2 diabetes suggested that hibiscus extracts help in lowering the low-density lipids (3) and increase the high-density lipid (4). Thus drinking hibiscus tea helps in controlling the cholesterol level of the body.
3. Prevents anemia by hibiscus tea
A dried calyx drink of hibiscus flower helps in the prevention of anemia. Mechanism of action is still unknown but research suggests that the prevention of anemia may be because of the increased activity of bone marrow to produce more red blood cells (5).
4. Rich in antioxidants
Hibiscus is rich in antioxidant compounds like anthocyanin, flavonoids, organic acids, and polysaccharides (6). These antioxidants thus make hibiscus drink a healthy choice for reducing the free radical scavenging activity.
This tea also acts as a mild laxative, therefore drinking hibiscus tea may help in resolving constipation problems (7).
Consumption of the tea made from hibiscus helps in relaxing the body and induces sleep, therefore, acts as a sedative. Studies show that this may be because it’s rich in antioxidants like flavonoids like hibiscitin and phenolic compounds may act like a sedative (8).
The extracts of the tea made from hibiscus have flavonoids, anthocyanin, and cholergic acids that possess diuretic and potassium-sparing properties. Therefore drinking this tea increases diuretic activity without losing the potassium and other minerals from the body (9).
Hibiscus extracts also act as a digestive. Studies suggest that hibiscus polyphenols enhance digestion by increasing the activity of the digestive and metabolic enzymes (10).
9. Reduces weight
This tea also helps in controlling the weight of the body and thus is a solution for obesity. The hibiscus polyphenols act as ligands that enhance the activity of metabolic and other digestive enzymes (10). Increased metabolism of the body further adds up to the weight reduction.
Some other health benefits are aphrodisiac, antiseptic, astringent, and anti-inflammatory.
