When the red carpet rosella flower petals, after centuries of wandering in the outside world because not ignored, are now red rosella returned with properties beneficial to mankind.
Food Science and Technology researchers have found levels of antioxidants in tea red petals. The amount is 1.7 mmmol / prolox, higher than the cat's whiskers are clinically proven antioxidant shed kidney stones.
The amount of antioxidants was obtained by grinding three florets rosela to 1.5 g powder and water were given 200 ml. The result is inserted into the spectrophotometer. Tools that analyze the chemical content based on the entire length of the refracted wave solution.
With the presence of antioxidants, free radical cells that damage the cell nucleus can be removed. That's why rosela have anticancer effects. The most played is anthocyanin. Anthocyanin plant pigments play a role maintaining cell damage from excessive ultraviolet light peyerapan.
Antihypertensive, John McIntosh examined the antioxidant content. Researchers from the Institute of Food Nutrition and Human Health, Massey University, the roselle extract by drying petals at a temperature of 50oC for 36 hours. Three grams oseile rouge-term results of roselle on France-drying was diluted in 300 ml of water. Solution was inserted into the tube spectrophotometer. The result roselle anthocyanin containing 51%, while 24% antioxidant.
Researchers tested the effectiveness of roselle anthocyanins to the inhibition of blood cancer or leukemia cells. Apparently, the natural pigment of Hibiscus sabdariffa not only inhibit the growth of cancer cells HL-60, but also turn it off. Doses are given only 0-4 mg / ml of roselle. Affecting anthocyanin delphinidin named 3-sambubioside.
Many people feel the direct benefits of roselle lowering high blood levels
With regular consumption of tea vinagreira-rosella in Portuguese-as refreshing sour taste.
After taking for 1 month can cause effects more calm because of neck stiffness and nervous tension due to hypertension is lost.
Tested zuring-term Efficacy of roselle calyx in Dutch-to hypertension proved Abd al-Aziz Sharaf from the Sudan Research Unit, Institute of African and Asian Studies. As quoted Planta Medical Journal in 1962, roselle petals are hypotensive, antihypertensive and antikejang-breathing. Thirty-seven years later, antihypertensive properties were examined clinically by M. Haji Faraji and A.H. Haji Shaheed Beheshti Tarkhani from the University of Medical Sciences and Health Services, Tehran, Iran. A total of 54 patients of high blood pressure in Tehran's Shariati Hospital and sistoliknya diastolic pressure was calculated 15 days before and after testing.
Patients were given a cup of tea consumption steeping 3 rosella flowers. After 12 days, the patient's average systolic fell 11.2%, diastolic pressure fell 10.7%. However, when consumption of roselle was stopped 3 days, systolic pressure increased by 7.9%, 5.6% diastolic. That proves roselle is efficacious lowering high blood pressure.
Because it implies a lot, then rosela can be a cure for people with gout, insomnia, to cholesterol.
Efficacy of anti-cholesterol observed by Vilasinee Hirunpanicha, from the Department of Pharmacology, Faculty of Pharmacy, Mahidol University, Thailand. Researchers were testing high-cholesterol rats. For 6 weeks, rats were divided into 3 groups were each given 1,000 mg and 500 mg per kilogram of body weight roselle, and mineral water.
As a result, serum cholesterol decreased 22% to roselle extract 500 mg / kg and 26% for 1,000 mg / kg weight. The decrease also occurred in serum triglycerides as much as 33% and 28%, and serum low density lipoprotein (LDL) levels by 22% and 32%.
Roselle grown in Jamaica began in 1707. roselle eaten raw as salad. Here rosela served as a traditional drink at Christmas. The trick is mixed with sliced ginger and sugar, then placed in a pot and pottery. After that, bring to a boil and let stand overnight.
Presented with additional ice and rum. Juice taste, aroma, and color similar to wine. Rosela have diverse properties and uses. Fortunately rosela bloom now back in Indonesia. That way the perceived benefits of roselle in Africa can also be obtained in Indonesia.
