Hibiscus tea is lovely and I drink it quite often. Hibiscus tea actually comes from part of the flower of the plant. The flowers hold the medicinal properties. A study conducted in 2004, published in Phytomedicine magazine, showed subjects who drank tea with 10 grams of dried calyces from Hibiscus for, four weeks had reduced blood pressure.There have been several other studies conducted since that points to evidence of this as well. Hibiscus tea in general contains antioxidants that help promote a healthy heart.
There have also been studies and evidence that hibiscus tea can help lower or maintain cholesterol levels, reduce inflammation, and aid an upset stomach. Drinking hibiscus tea may help with digestion, and prevent an upset stomach by helping relax the smooth muscle of the intestine. Additionally, Hibiscus has been used for things like treating coughs, poor appetite, and its antibacterial or anti-fungal properties.
