If you have traveled to Mexico, then chances are that you’ve seen the vibrant, scarlet-hued herbal tea known as hibiscus. Commonly referred to as “sour drink” in Iran, hibiscus not only is a refreshingly tart brew but also has been used worldwide as an effective medicinal beverage. Rich in vitamin C, alkaloids and bioflavonoids, this bright-red elixir is traditionally used for supporting respiratory and cardiovascular health, lowering blood pressure, maintaining fluid balance and alleviating insomnia. And now, contemporary research has validated the herb as a( health-promoting tonic in a variety of areas. )
Historical uses, modern applications
Originally grown in Angola, the cultivation of Hibiscus sabdariffa has spread around the world to such subtropical regions as Sudan, China, Egypt, Mexico and Thailand.
“In Egypt and Sudan, hibiscus is used to help maintain a normal body temperature, support heart health, and encourage fluid balance. North Africans have used hibiscus internally for supporting upper respiratory health including the throat throat and also use it topically to support skin health. In Europe, hibiscus has been employed to support upper respiratory health, alleviate occasional constipation, and promote proper circulation. It is commonly used in combination with lemon balm and St John’s Wort for restlessness and occasional difficulty falling asleep,” states Naturopathic Doctor Tori Hudson.
Presently, studies on hibiscus have shown it to be beneficial for reducing cadmium toxicity , easing Parkinson’s disease  and lowering blood pressure. 
Moreover, research has indicated a positive connection between hibiscus consumption and managing metabolic syndrome, as well as cholesterol levels. Dr. Hudson notes:
“Hibiscus extract was also studied in 222 patients–some with and some without metabolic syndrome (MS). A total daily dose of 100 mg H. sabdariffa extract powder (HSEP) was given for 1 month to men and women, 150 without MS and 72 with MS. Participants were randomly assigned to a preventive diet, HSEP treatment or diet combined with HSEP treatment. The MS patients receiving HSEP had significantly reduced glucose, total cholesterol and LDLc and increased HDLc. A triglyceride lowering effect was seen in all groups but was only significant in the control group that was treated with diet. The triglyceride/HDL-c ratio was also significantly reduced with HSEP in the control and MS groups, indicating an improvement in insulin resistance. It has been hypothesized that the anthocyanins regulate adipocyte function, which has important implications for both preventing and treating metabolic syndrome.”
