Benefits of a dietary supplement of black radish

Black radish is known to help treat digestive disorders due to poor bile circulation, but also inflammation and hypersecretion of the upper respiratory tract (colds, sinusitis, etc.). As a result, black radish food supplements are given antibacterial and antiseptic properties, thanks to the quantities of isothiocyanates, glucosinolates or raphanin that it contains. Since there are quantities of black radish that should not be exceeded, it is advisable to seek the advice of your doctor before starting a course. Note that black radish can cause gastrointestinal upset, heartburn or heartburn in some people. Also, if you suffer from bile duct obstruction, it is mandatory to consult your doctor.

History of black radish

The origins of radish date back several centuries before our era. First cultivated in China, it would later have conquered the ancient Greeks and the Romans. It seems that we had to wait until the XVIIIe century before the Black radish, originally from Eastern Europe, is consumed in France.

Botanists believe that the Black radish was the first species of radish cultivated by humans. We know that the Egyptians cultivated it already at the time of the pharaohs, because we found, in the temple of Karnak, hieroglyphs representing it.

The species Raphanus sativus includes several varieties of radishes. Among the best known are the red or pink radish (Raphanus sativus var radicula) that we often find on our plates, and the daikon ((Raphanus sativus var longipinnatus), a large white radish widely used in Japan.

All these radishes have more or less the same properties, but in Western herbalism, the Black radish was preferred for medicinal uses.

Black radish ingredients

Black radish contains large amounts of isothiocyanates – compounds found in mustard – as well as glucosinolates, organic compounds that are also found in mustard.

Isothiocyanates have normal doses of antibacterial and / or insecticidal properties, while glucosinlates have antifungal, antibacterial, anti-carcinogenic and anti-mutagenic properties.

It also contains raphanin, with antiseptic and antibacterial properties, as well as a significant amount of vitamin C2 (114 mg / 100 g) and potassium (554 mg / 100 g).

Black radish research

Biliary stimulation

The German Commission E approved the use of freshly squeezed black radish juice to treat dyspepsia resulting from poor bile circulation. Despite the absence of clinical trials to demonstrate the efficacy of Black radish for this purpose, Commission E found that traditional use, as well as in vitro and animal testing, speak volumes enough to recognize the benefits of black radish juice. According to this organism, it stimulates the peristaltic movements of the intestine and it acts on the bile ducts, thereby promoting bile secretion and good digestion.

Various

Studies in vitro and in animals have shown that black radish contains several compounds that can have a positive effect on human health. Here are the main ones.

  • Antioxidants that limit the oxidation of blood lipids (an effect favorable to cardiovascular health) and intestinal cell lipids (a beneficial effect for the prevention of colon cancer).

A beneficial effect of black radish on the cardiovascular system is possible, according to a study by a team of Mexican researchers. They report that a juice obtained from black radish root lowers blood lipid levels in mice. After 6 days of treatment, it appears that black radish lowers cholesterol in bile, one of the causes of gallstones, and also lowers blood levels of cholesterol and triglycerides, while HDL cholesterol (the good cholesterol) increase.

  • Substances that slow down the multiplication of human cancer cells and stimulate their apoptosis, in vitro.

Korean researchers have isolated the active ingredients of black radish to assess their anti-inflammatory and anti-cancer properties. Their results indicate that the 7 identified compounds – derivatives of 4-methylthio-butanyl – have the ability to reduce inflammation and cell proliferation in cell culture models.

  • Substances that activate certain enzymes to detoxify the liver.

A trial conducted with daikon radish sprouts (Raphanus sativusvarlongipinnatus) indicates that consumption of the latter may lower blood glucose and insulin levels in diabetic rats.

  • Isothiocyanates (eg sulforaphane), capable of inactivating a formidable bacterium, Helicobacter pylori whose long-term effect increases the risk of gastric cancer.
  • Glucosinolates that have protective properties.

A study in rats indicates that the carcinogen called dimethylbenzanthracene (DMBA) causes toxicity in bone marrow cells. When rodents are treated with black radish, researchers observe stimulation of detoxifying enzymes, a reduction in DMBA levels in the blood and an increase in bone marrow cells, supporting the hypothesis that the glucosinolates present in black radish have protective properties.

Precautions with black radish

Contraindications

  • Do not take when you have bile duct obstruction.

Side effects

  • Some people find it hard to tolerate black radish juice, which causes gastrointestinal upset and heartburn or heartburn. The dose should then be reduced or, if the problems persist, turn to another treatment. You can also take the juice with a little vegetable oil, which is sometimes enough to protect the walls of the digestive system against the irritation that can cause sulfur substances of black radish.
  • An allergy case manifesting as generalized hives has been reported in a person who consumed black radishes.
