ROSELLE TEA (infusion Hibiscus sabdariffa) from AMAZON HERBS® |
Overview Roselle (Hibiscus sabdariffa) has antioxidant effects and enhances cardiovascular health. It has been shown to relax the uterus. It has also been used for indigestion (control of diarrhea), loss of appetite, as well as for colds, respiratory problems and circulation disorders. Roselle has antibacterial and anti-oxidant properties; lowers the blood pressure (hypotensive effect). It may be as potent as the drug Captopril (Capoten) in this regard. It is also antispasmodic (decrease spasms in the stomach, intestines, and uterus) and work like antibiotics to kill bacteria and worms (anthelmic). Roselle significantly reduces cholesterol content in blood serum and prevents oxidation of low-density lipoproteins. It can suppress blood lipid levels, including triglycerides and total cholesterol, significantly. Roselle is potentially applicable to prevent atherosclerosis in humans due its anti-hyper-lipidaemic effect and anti-LDL oxidation. It may therefore be useful in the prevention of a number of cardiovascular diseases in which cholesterol plays a major role. Phyto-chemicals Roselle contains 49 calories, 84.5% H2O, 1.9g protein, 0.1g fat, 12.3g total carbohydrate, 2.3g fiber, 1.2g ash, 1.72mg Ca, 57mg P, 2.9mg Fe, 300?g ? Carotene equivalent, and 14mg ascorbic acid. Presence of saponins, tannins, cyanogenic glycoside Other phytochemicals are protocatechuric acid and anthocyanins. Pharmacology Extract of Roselle inhibits serum lipids and shows an antiatherosclerotic activity. It also have shown other properties in the test tube and in animal studies, such as reducing skin cancer promoted by ultraviolet light, inhibiting herpes simplex virus. Several studies have looked at the potential use of hibiscus for male and female fertility. Also in other studies, it was found that Roselle tea has a substantial antihypertensive effect attributable to the flower's ACE-inhibiting anthocyanin content, and possibly to a diuretic effect. One study found that Roselle conferred an antihypertensive effect comparable to 50 mg./day of the drug Captopril. Another study found it to be less effective than Lisinopril, but it showed 100% tolerability (absence of intense side effects). Probably it acts to lower blood pressure through being an ACE inhibitor. A study in mice found that Hibiscus sabdariffa can prevent liver damage caused by acetaminophen, the active ingredient in Tylenol and a number of other pain-killers, which is known to cause liver damage in high enough doses. 
Dosage Tincture: 1 - 3 ml, daily ( 1 - 3 full droppers) Infusion: 1 - 2 cups daily Precaution Due to the hypotensive effect caution is expressed when using with other blood lowering medicine.
