Most studies showing a benefit of hibiscus tea on blood fat levels have been limited to people with specific health conditions, such as metabolic syndrome and diabetes.

US sales of brew and ready-to-drink teas Increased in 2014 [Press release] However, all these studies assessed the effects of hibiscus extract rather than hibiscus tea. Further research is necessary to find out how hibiscus tea affects liver health in humans. Summary Nwachukwu DC, Aneke EI, Nwachukwu NZ, Azubike N, Obika LF.

J Physiol Sci. 2017;67(1):227-234. doi:10.1007/s12576-016-0458-z Drinking hibiscus tea in moderation is generally considered safe. However, other products containing hibiscus are not regulated and may or may not contain what they claim. These include: Da-Costa-Rocha I, Bonnlaender B, Sievers H, Pischel I, Heinrich M. Hibiscus sabdariffa L. - a phytochemical and pharmacological review. Food Chem. 2014;165:424-443. doi:10.1016/j.foodchem.2014.05.002With the Hibiscus sabdariffa, one of the edible hibiscus plants, many parts of the plant are edible. Among the Yoruba in southwest Nigeria, Roselle is known as ìsápá, and yakuwa by the Hausa people of northern Nigeria who also call the seeds gurguzu and the capsule cover zoborodo or zobo. [8] [9] [10] In Nigeria, roselle jam has been made since colonial times and is still sold regularly at community fetes and charity stalls. It is similar in flavour to plum jam, although more acidic. It differs from other jams in that the pectin is obtained from boiling the interior buds of the roselle flowers. It is thus possible to make rosella jam with nothing but roselle buds and sugar.

One of the main reasons for the cultivation of roselle is to produce bast fibres which are extracted from the stem and are used as a substitute to jute. Hibiscus cannabinus is commonly cultivated in southern Asia for fibre extraction purposes.Beetroot juice: Substances found in beetroot juice may reduce blood pressure in healthy individuals as well as those with prehypertension. Researchers from one review believe that beetroot juice is a cost-effective and safe treatment option for blood pressure reduction. However, they admit that more research is needed. Roselle has been used as a therapeutic plant for centuries. Traditionally, it treats toothaches, urinary tract infections, colds, and even hangovers. In Senegal, roselle juice extracted from leaves is used to treat conjunctivitis and, when pulverized, soothes sores and ulcers.

In one small study, 46 people with high blood pressure consumed either hibiscus tea or a placebo. After 1 month, those who drank hibiscus tea had a greater decrease in systolic and diastolic blood pressure than those who took the placebo ( 6). Raina R, Verma PK, Peshin R, Kour H. Potential of Juniperus communis L as a nutraceutical in human and veterinary medicine. Heliyon. 2019;5(8):e02376. doi:10.1016/j.heliyon.2019.e02376 Khasiat tanaman rosella tidak terlepas dari kandungan antioksidan yang tinggi, sehingga mampu menangkal radikal bebas yang dapat menyebabkan kerusakan sel dan jaringan tubuh. Selain itu, tanaman rosella juga memiliki manfaat lain, di antaranya: 1. Menurunkan tekanan darah Roselle is used in Nigeria to make a refreshing drink known as Zobo and natural fruit juices of pineapple and watermelon are added. Ginger is also sometimes added to the refreshing drink. [32]The treatment is dried rosella calyx and mixed with 150ml of boiling water. Rosella dose is 2 grams or the equivalent of 5 calyces, given as much as 2x/day. Administration time was in the morning (8.00–8.30 a.m.) and evening (06.00–07.00 p.m.) after meals. Treatment was given for 21 days. Rosella contains some antioxidants such as flavonoids, polyphenolic acids, anthocyanins, and protocatechuic acid [ 26, 31]. Rosella also has cardioprotective actions [ 31]. Rosella decreases lipid peroxidation in the liver through the lipopolysaccharide (LPS) activity pathway [ 28]. LPS activates inducible nitric oxide synthase (iNOS) to stimulate NO production. iNOS is found in several places such as endothelial cells, hepatocytes cells, and Kupffer cells [ 28]. Polyphenols play a role in stimulating the secretion of NOS enzymes via the Pi3-K/Akt pathway [ 26]. Polyphenols result in relaxation of smooth muscle and activate potassium channels in a smooth muscle through nonendothelium-dependent relaxation pathways [ 26]. The interactions of Roselle and weight loss are not too clear-cut, and it seems to be highly intertwined with studies on Roselle toxicity; Roselle is known to be toxic in higher doses, and weight loss more often than not precedes chronic toxicity. For studies that note weight loss without toxicity, it seems to be related to reduced food intake in rats and mice rather than direct fat burning effects. More large-scale studies examining the effects of hibiscus tea on blood cholesterol and triglyceride levels are needed to determine its potential effects in the general population. Summary Tak hanya itu, suplemen maupun teh rosella juga diketahui dapat menurunkan tekanan darah dan mencegah hipertensi atau tekanan darah tinggi. Namun, penggunaan teh rosella sebagai obat untuk mengatasi hipertensi tentunya harus dikonsultasikan lebih dulu dengan dokter. 2. Mengatasi kolesterol tinggi

Examination of bodyweight (BW) was performed using a measuring scale weight (GEA ZT-120). Examination of blood pressure (BP) was performed using mercury sphygmomanometer (Riester) and stethoscope (Littmann). Measurement of blood glucose (BG) levels was used by the glucose oxidase (GOD-PAP) method. Total cholesterol (CT) was measured by the cholesterol oxidase-phenol aminophenazone (CHOD-PAP) method. Triglyceride (TG) levels were measured using an enzymatic colorimetric method with glycerol-3-phosphate oxidase-phenol aminophenazone (GPO-PAP). High-density lipoprotein (HDL) and low-density lipoprotein (LDL) levels were examined using homogeneous methods.The dried calyces and as well as the dried flower is also used as an essential ingredient in various recipes. Skincare Our findings regarding the potential of rosella as herbal medicines for antihypertension is supported by the theory regarding the mechanism of action of rosella in controlling blood pressure. Rosella is working in regulating cardiac output and peripheral vascular resistance, thereby reducing blood pressure and antihypertensive activity [ 23]. Rosella works as an angiotensin-converting enzyme (ACE) inhibitor and inhibits α-glucosidase and α-amylase, calcium channel modulation, and vasorelaxant effect [ 23, 26]. We found that rosella increases NO secretion. Rosella slightly increases NO levels in rats [ 27]. NO is a vasodilator, secreted by nitric oxide synthase (NOS) [ 28]. Rosella decreases lipid peroxidation and lesions in the liver, increasing the activity of the catalase and glutathione enzymes [ 28]. Flavonoids and anthocyanins in rosella have a diuretic effect and act as a modulator of aldosterone action and regulate blood pressure [ 22, 23]. Rosella Cheesecake– that uses rosella jam in the cheesecake filling, and rosella syrup to make the jelly topping. Selain manfaat-manfaat di atas, rosella juga mengandung senyawa antioksidan yang dapat mengatasi peradangan dan mengurangi risiko kanker.
