Rosela, the Red with Various Benefits for Health

Many already know and are familiar with roselle or roselle (Hibiscus sabdariffa). This plant is still in the same family as hibiscus flowers and is commonly processed into herbal teas.

Based on a study entitled “Nutritional and health importance of Hibiscus sabdariffa: a review and indication for research needs” in the Journal of Nutritional Health & Food Engineering in 2017, rosella is a medicinal plant that is safe for consumption.

Rosella is known to contain various important compounds, namely photochemicals which can be used to support the treatment of several diseases or health conditions. For more details, here is a summary of some sources regarding the health benefits of roselle.

1. Able to reduce cholesterol levels

Research in the Journal of Nutritional Health & Food Engineering in 2017 looked at high cholesterol patients who were given roselle extract three times a day. As a result, the ethanol extract of rosella leaves showed significant results. The research team concluded that the ethanol extract in rosella leaves reduced glucose, total cholesterol, and low density lipoproteins.

A study in the journal Food Chemistry in 2014 explained that water and ethanol extract from dried roselle leaves can reduce levels of low-density lipoprotein (LDL) or bad cholesterol, triglycerides, total cholesterol, and peroxi-daxionin lipids in vivo. The groups of compounds in the extract are anthocyanins and protocatechuic acids.

2. Lower blood pressure

According to a report entitled “Hibiscus Tea and Health: A Scoping Review of Scientific Evidence” in the journal Nutrition and Food Technology published in 2020, giving 240-250 ml of roselle tea daily can lower blood pressure in people with blood pressure. high or hypertension.

These properties are related to the anthocyanin content contained in rosella flowers.

3. Has strong antioxidants

Rosella flower petals are found to contain powerful antioxidants. Antioxidant compounds found in roselle petals include polyphenolic acid, flavonoids, and anthocyanins.

Antioxidants act to ward off free radicals that enter the body. Therefore, the high content of antioxidants can protect the body from various infectious diseases.

4. Has an antidiabetic effect

Sourced from a report in the journal Food Chemistry in 2014, a study was conducted on mice with diabetes. From there, it was found that giving rosella flower extract containing 200 grams of ethanol per kg had strong hypolipidemic and antioxidant properties.

In rosella extract, there are polyphenol compounds and dihydrobenzoic acid, which these compounds have an effect on reducing and preventing the development of atherosclerosis.

In addition, further research was carried out in humans, it was said that roselle tea provided significant benefits on the blood lipid profile by increasing high-density lipoprotein (HDL) or good cholesterol, decreasing total cholesterol, and reducing LDL and triglyceride levels.

5. Reducing the risk of obesity

Hibiscus extract is able to inhibit amylase activity. Apart from that, Hibiscus extract can also help inhibit the absorption of starch and sugar, so it is suitable for people who want to lose weight.

6. Prevent cancer

Rosella plant is rich in phenolic compounds. Phenolic compounds exert a protective effect on cytotoxicity and genotoxicity induced with tert-butyl-hydroperoxide.

The workings of phenolic compounds are reducing the type of reactive oxygen-cies (ROS), DNA fragmentation, G1 capture, and apoptosis.

Those are some of the benefits of the roselle plant that are healthy. However, further research is needed to really know its benefits and potential side effects. Make sure not to overdo it, yes. For pregnant and lactating women, you should consult a doctor before consuming it.
