What is kombucha tea

Kombucha tea is a fermented decoction prepared by mixing a symbiotic colony of bacteria and yeast (SCOBY) with any regular tea leaves, preferably black tea or green tea, and sugar. Since the mass of yeasts and bacteria growing on the surface of the infusion resembles a mushroom, the infusion is sometimes referred to as kombucha mushroom tea even though it’s not made from mushrooms. It is considered to be one of the popular varieties of fermented tea containing essential nutrients, beneficial for several health ailments.

History and origin

Although the intake of the health-boosting drink was common among the people of East Russia in 1900, it eventually gained recognition in Europe. In 1913, kombucha was also described in German literature.  During the early 20th century, exclusive research was done in Germany and Russia to finds its health benefits. Based on some experiments, its use was linked to cancer treatment since a large percentage of people in Russia were at a lower risk of cancer. It gradually came into use in the US by the mid-1990’s.

Kombucha fermented tea health benefits: What is it good for

For immunity

In addition to being rich in antioxidants beneficial for fortifying the immune system, one of its component D-Saccharic acid 1, 4-lactone (saccharolactone), formed during the fermentation process also exhibits antioxidant properties that, along with vitamin C, improves the functioning of a compromised immune system caused due to certain inflammatory disorders, cellular damage, and tumors.

Besides having anti-inflammatory properties, the acetic acid produced by the probiotics in the fermented beverage displays antimicrobial activity, providing protection from a host of bacterial and viral infections.

Detoxification

Its detoxifying ability is attributed to the presence of glucuronic acid, responsible for improving the condition of the liver by flushing out the toxins through the kidneys, which in turn has positive effects on the pancreas as well. According to some research studies, the antioxidants inhibit the liver cells from undergoing oxidative damage by the toxins.  It also aids in neutralizing the harmful effects of pollutants like toxic metals, chemical wastes, and pesticides.

Helps in digestion

Its probiotics, digestive enzymes, organic acids and antioxidants play a vital role in boosting digestion, preventing the risk of several gastrointestinal conditions, including constipation, diarrhea, heartburn, and GERD. The enzymes also facilitate smooth digestion of saccharides and proteins by stimulating the glucuronic acid.

Being a source of polyphenols, it protects the digestive enzyme mucin, suppressing the secretion of gastric acids, providing relief from gastric ulcers. The probiotic-rich drink has several beneficial yeasts and bacteria that aid in restricting the growth of Candida in the gastrointestinal tract, reducing the chances of infection.

Useful for arthritis

Weight loss

According to some previous studies, it may assist in boosting metabolism, and hence inhibiting the accumulation of fats. Having acetic acid and polyphenols also makes it effective for controlling weight.

Boosts energy levels

When prepared using black tea, it provides iron that binds to the hemoglobin in the body, increasing oxygen supply to the tissues, and thus yielding more energy, making you feel active.

For skin

Since the fermented infusion preserves the collagen in the skin tissues, its consumption can help in maintaining the elasticity and tone of the skin. Besides having skin-moisturizing effects, it may also help in reducing wrinkles, scars, age spots, acne, eczema, psoriasis, rashes, and scars.

Studies show the glucaric acid in the fermented drink to have cancer-fighting properties, making it potentially beneficial for curbing the risk of several types of cancer. Its intake might be a useful remedy for raising the levels of HDL cholesterol, minimizing the absorption of LDL cholesterol and triglycerides as well as for managing depression, stress-related anxiety problems, Lyme disease, and fibromyalgia.

Rinsing the hair with the fermented infusion can help in hair growth and prevent graying of hair.
