Continue reading to learn more about this tea, its brewing method, and the health benefits it may provide.

What Is Kombucha Tea and Why Should You Drink It?

Kombucha tea, often known as kombucha, is a fizzy, sweet-sour fermented beverage produced from sweetened tea and a microbial culture known as SCOBY (Symbiotic Culture Of Bacteria and Yeast).

While converting the sugar in the tea to ethanol (alcohol) and acetic acid, the bacteria and yeast reproduce and thrive. This acetic acid is what gives kombucha its peculiar sweet-sour flavor.

Kombucha contains significant anti-inflammatory, antioxidant, and gut and liver healing qualities due to scoby fermentation.

That is why health nuts all over the globe are praising it as the ideal alternative to bubbly, sugary, carbonated beverages.

How to make kombucha tea

Note: Maintain a ratio of 1 cup of sugar, 8 tea bags, and 2 cups of starting tea per gallon of kombucha tea (scoby cultures).

Follow the given steps

  • Sugar and tea leaves should be steeped in boiling water.
  • Add the scoby cultures after the tea has cooled.
  • Mix everything well, then pour into sealed containers with a little extra sugar and allow to ferment for two weeks. Serve cool, garnished with fruits and spices.

Health Benefits of Kombucha Tea

1. It has hepatoprotective effects.

The liver is your body’s ‘downtown,’ where all the activity takes place.

Fatty acids and lipids, as well as medications, are broken down in the liver, which is why it is one of the organs that suffer the most damage and requires the most attention.

Acetobacter and yeasts found in kombucha tea have been demonstrated to have outstanding hepatoprotective capabilities.

Acetic acid is converted by these bacteria into glucuronic acid, a powerful antioxidant.

Flavonoids like theaflavins, thearubigins, and their derivatives are also found in green and black tea leaves, which help glucuronic acid scavenge free radicals and toxic intermediates that cause tissue damage.

Kombucha tea also prevents hepatotoxicity and chronic inflammation by inhibiting linolenic acid and lipid peroxidation.

Because scoby cultures ferment kombucha tea, it’s high in gut-friendly bacteria like Gluconacetobacter, Acetobacter, and Lactobacillus, as well as fungal species like Zygosaccharomyces, Candida, and other yeasts.

Such symbiotic cultures aid in the maintenance of optimal biochemical conditions in the stomach for efficient digestion.

These bacteria aid in the breakdown of complex lipids, fatty acids, and potentially toxic derivatives that build up in your body.

3. It has a heart-protective effect.

Kombucha offers heart-healthy properties.

Kombucha tea’s antioxidative and antilipidemic properties increase good cholesterol (HDL) levels while lowering bad cholesterol (LDL) levels, as well as unwanted free radicals and intermediates, in your blood vessels.

As a result, the blood pumped to your heart is cleaner, and the blood vessels are less congested with plaque and cholesterol deposits.

The heart doesn’t have to exert as much pressure to pump blood in and out of the body when the blood is cleaner and the blood vessels are dilated.

Kombucha may protect your heart from problems like atherosclerosis, myocardial infarction, and hypertension if you drink it instead of tea or coffee.

4. Can Help To Prevent And Treat Cancer

One of the reasons for tumor growth in your body is an increase in reactive oxygen species (ROS).

These ROS (such as peroxide and superoxide ions, heavy metal intermediates, and accumulated xenobiotic residues) may promote tumor metastasis, which can be fatal if left untreated.

Kombucha tea may help you out in this situation. It’s chock-full of antioxidants, vitamins, and probiotic microorganisms that may successfully treat inflammation and reduce ROS.

Caffeine derivatives, phenolic acids, polyphenols, terpenes, and vitamins in kombucha may scavenge ROS from practically every nook and cranny of your body, protect you against inflammation-induced cancer, and even stop it from spreading.

5. Aids And Protects Your Gut Digestion

kombucha improve digestion

Kombucha is a fermented tea that improves digestion.

Gastritis is one of the most prevalent side effects experienced by habitual tea drinkers, hence it’s uncommon for tea to have gastroprotective characteristics.

Drinking kombucha tea prepared with green tea leaves, on the other hand, is both soothing and energetic.

That’s because the scoby cultures in kombucha have a high probiotic value, which means they contribute good bacteria to your stomach to aid with digestion, absorption, and bowel movements. As a result, this tea is sometimes prescribed for persons who have constipation or irritable bowel syndrome (IBS). If someone has IBS caused by Small Intestine Bacterial Overgrowth (SIBO), however, kombucha may exacerbate the issue.

Kombucha extracts have significant antioxidant activity as well as the potential to preserve gastric mucus content.

This gut-friendly beverage also has anti-ulcer qualities, since it lowers stomach acid output and aids ulcer healing.

6. Is An Antioxidant Treasure Chest

Because of its antioxidative effects, this tea has earned the moniker “health drink.”

According to studies, scoby cultures fermenting kombucha tea increase antioxidant levels such as phenolic acids (rosmarinic acid, coumaric acid, linolenic acid, caffeic acid, ferulic acid, gallic acid, chlorogenic acid, etc. ), polyphenols (catechins, rutin, theaflavins, thearubigins, quercetin, and other flavonoids), and other flavonoids.

These bioactive components effectively scavenge free radicals such as peroxides, boost the activity of enzymes like SOD and catalase, and remove harmful intermediates, heavy metals, and xenobiotic contaminants.

Simply said, making kombucha a habit might help you avoid a slew of ailments, including acne, pimples, wrinkles, and hair loss, as well as atherosclerosis, renal failure, cirrhosis, and urinary tract infections.

You may try brewing kombucha with several types of tea, such as green tea, black tea, and lemon balm tea, in conjunction with SCOBY cultures from various sources to achieve the optimum antioxidative effects.

7. Assists in the treatment of inflammatory diseases

Inflammatory disorders such as arthritis, diabetes type 2, asthma, irritable bowel syndrome, certain UTIs, psoriasis, dermatitis, ulcers, GERD, and renal failure may all be helped by fermented liquids like kombucha tea.

Flavonoids, caffeine derivatives, polyphenols, vitamins C and B complex, and trace minerals like iron, copper, nickel, zinc, and lead in kombucha tea, especially the one brewed with oak leaves, inhibit the production of pro-inflammatory chemical messengers like IL-6 and TNF-, as well as nitric oxide, which can cause tissue damage in the surrounding area.

8. Powerful Antibacterial Agent

In a study, kombucha tea was found to have antimicrobial activity against a variety of pathogenic organisms, including Staphylococcus aureus, Shigella sonnei, Escherichia coli, Aeromonas hydrophila, Yersinia heterolytic, Pseudomonas aeruginosa, Enterobacter cloacae, Staphylococcus epidermis, Salmonella enter it.

As a byproduct of tea fermentation, the SCOBY produces acetic acid, which is primarily responsible for its antibacterial properties.

Other than acetic acid, other components in kombucha have been shown to have substantial antibacterial action, according to research.

Cellulitis, urinary tract infections (UTIs), whooping cough, diphtheria, typhoid, and other bacterial illnesses may all be helped by drinking kombucha tea.

9. Promotes Health And Longevity

Including kombucha tea in your diet may help you live longer, even if your lifestyle changes.

Kombucha helps boost memory, has anti-aging effects, promotes hassle-free metabolism, ensures organ health, and, most importantly, flushes out toxins from your body that can accelerate all of the above events thanks to the antioxidative, anti-inflammatory, neuro-, cardio-, and hepatoprotective phytochemicals.

Side Effects of Kombucha Tea

I’m sure you’ve noticed that kombucha tea is a ‘fermented’ beverage. Even though it only contains around 0.5 percent alcohol, extended storage might raise the level to up to 5%!

Aside from the alcohol, consuming kombucha implies allowing millions of bacteria to enter your body. The damage that kombucha may cause in your body if it goes sour or is allowed to ferment too long is terrifying!

Some side effects that may arise are as follows:

1. Toxicity of the Liver

Drinking kombucha tea that is over fermented, aged, and turbid might induce jaundice and other liver problems. It may lead to chronic liver inflammation and failure if left untreated.

This issue might arise as a consequence of consuming kombucha, which has a high and crude alcohol concentration.

2. Acidosis 

Because kombucha tea contains acetic acid and other derivatives, it should always be used under medical supervision, particularly if you have gastritis, recurrent ulcers, or other medical conditions.

Drinking mature kombucha may also induce severe acidosis (excess acid in the body), which can lead to death if not treated.

3. Nausea and hypersensitivity

The SCOBY microorganisms in kombucha tea may cause skin allergies in certain individuals.

If you attempt a new or fresh batch of SCOBY culture or a different brand of prepared kombucha tea, nausea, headache, diarrhea, and neck discomfort may occur.

If this is the case, consider lowering your consumption and keeping an eye on your health. If you’re still experiencing these symptoms, stop drinking kombucha and visit a doctor right once.

4. Possibility of causing problems in diabetics

Kombucha contains enough sugar to keep the SCOBY fermentation going. If you already have diabetes, it might raise your blood glucose levels and harm your organs.

Consult an endocrinologist to determine whether you are hyperglycemic, and then follow the dose or alternatives prescribed.

5. Dangerous If Your Immunity Isn’t Strong Enough

Virus infections (HIV-AIDS) and post-operative stress, for example, might reduce your immunity.

Because kombucha contains a variety of microbial strains, a weakened immune system may lead to long-term bacterial and fungal illnesses.

Such infections may be life-threatening if you ignore the symptoms.

6. Obstacles To Pregnancy And Breastfeeding

There isn’t enough information on this drink’s safety for pregnant and nursing women.

As a result, it’s best to avoid kombucha during pregnancy and nursing to prevent needless issues.

Kombucha tea is fermented with yeast and bacteria over time. Fermentation gives it antioxidative and anti-inflammatory properties that benefit your health. It cleanses and detoxifies while protecting your stomach and liver. Kombucha tea’s phenolic acids, polyphenols, and flavonoids improve cardiovascular health, fight inflammation, and prevent lifestyle problems. Thanks to its absence of cholesterol and saturated fats, it’s a healthy summer drink or calming cure for gastrointestinal problems. While its health benefits are growing, its safety and detrimental consequences for pregnant and nursing women remain unclear.
