What Is Kombucha Tea?

Kombucha tea or kombucha is a fizzy, sweet-sour, fermented, non-alcoholic drink made from sweetened tea with a specific microbial culture called SCOBY (Symbiotic Culture Of Bacteria and Yeast).

The bacteria and yeast grow and multiply while they convert the sugar in the tea to ethanol (alcohol) and acetic acid. It is this acetic acid that gives kombucha its characteristic and distinctive sweet-sour vinegary taste.

Because of the scoby fermentation, kombucha has potent anti-inflammatory, antioxidant, and gut and liver healing properties.

And that is why it is being touted as the best alternative to the effervescent, sweet, carbonated drinks by health freaks all over the world.

But where did this delicious beverage come from? While the exact origin of kombucha tea is uncertain, It is believed to have originated in Northeastern China, where it has been consumed for centuries for its potential health benefits. It is said to have spread widely to different parts of Europe and Asia, namely Russia and Korea via the silk route.

If you are looking to purchase kombucha tea, it is important to note that the price depends on factors like the brand, bottle size, and location. A single bottle of kombucha tea can cost anywhere between $3 to $5 at a grocery store. However, prices can be higher for specialty or premium brands. You can try making kombucha tea at home as it is cost-effective.

So, how do you make this tea? Let’s find out!

How Is Kombucha Tea Made?

Note: For every gallon of kombucha tea, maintain the ratio of 1 cup of sugar, 8 bags of organic tea, and 2 cups of starter tea (scoby cultures).

  1. Steep sugar and tea leaves in hot water.
  2. Once the tea is cold, add the scoby cultures.
  3. Mix the contents well, pour into airtight containers with some more sugar and leave to ferment for about two weeks. Serve cold with some added fruits and spices.

Yes, it’s that simple!

Nicki and Ben, two bloggers, shared their experience of making and consuming kombucha tea on their blog. One of the bloggers states, “I’ve been brewing kombucha continuously for a couple of years now. When we were kids, I remember helping my mum brew it. We used a mix of black and fruit teas then, and when I first moved into my own place, I started again (i).”

But then, you might ask, so what if it has scoby cultures? Why’s there so much hype about kombucha?

How is it different from other health drinks? What does it do to your body that makes this tea so valuable and unique?

I have the answers to all your questions – only if you read ahead!

What Are The Benefits You Get By Drinking Kombucha Tea?

1. Has Hepatoprotective Properties

The liver is the ‘downtown’ of your body where all the action happens.

Fatty acids and lipids are broken down in your liver, and so are the drugs – which is why the liver is one of those organs that suffer the highest damage and need a lot of care.

Bacterial species like Acetobacter, along with the yeasts, in kombucha tea have shown exceptional hepatoprotective properties.

These bacteria convert acetic acid to glucuronic acid, which is a potent antioxidant.

Also, the green and black tea leaves have flavonoids like theaflavins, thearubigins, and their derivatives, which assist glucuronic acid in scavenging free radicals and toxic intermediates that trigger tissue damage.

Kombucha tea also inhibits linolenic acid and lipid peroxidation that lead to hepatotoxicityi  XLiver damage from chemicals primarily caused by drugs that can result in acute and chronic liver disease. and chronic inflammation (1).

2. Protects Your Gut And Aids Digestion

It is unusual for a tea to have gastroprotective properties because gastritis is one of the most common side effects regular tea-o-holics face.

But surprisingly, drinking kombucha tea brewed with green tea leaves soothes your GI tract and gives you energy.

That’s because the scoby cultures in kombucha have high probiotic value, adding healthy bacteria into your gut in order to help with quick and clean digestion, assimilation, and also in passing bowel movements. Hence, this tea is sometimes recommended for people suffering from constipation and irritable bowel syndrome (IBS). However, if someone has IBS that is induced by Small Intestine Bacterial Overgrowth (SIBO), kombucha may make the problem worse.

Kombucha extracts have high antioxidant activity as well as the ability to protect the mucin content of the gastric tissues.

This gut-friendly drink also has anti-ulcerative properties since it reduces the gastric acid secretion and helps in rapid ulcer healing (2).

3. Helps In Weight Loss and Detox

Since scoby cultures ferment the kombucha tea, it is rich in gut-friendly bacteria like Gluconacetobacter, Acetobacter, and Lactobacillus and fungal species like the yeast Zygosaccharomyces, Candida, etc. (3).

Such symbiotic cultures help in maintaining the ideal biochemical conditions in your gut for effective digestion.

These microbes assist in metabolizing complex lipids, fatty acids, and harmful derivatives that tend to accumulate in your body.

4. Is A Treasure Trove Of Antioxidants

This tea gained the sobriquet of the ‘health drink’ mostly due to its natural antioxidative properties.

Research says that fermentation of kombucha tea by the scoby cultures increases the levels of antioxidants, such as phenolic acids (rosmarinic acid, coumaric acid, linolenic acidi  XAn omega-3 essential fatty acid found in high levels in certain plant oils that helps reduce inflammation. , caffeic acid, ferulic acid, gallic acid, chlorogenic acid, etc.), polyphenols (catechins, rutin, theaflavins, thearubigins, quercetin, etc.), and other flavonoids (4).

These bioactive components robustly scavenge the free radicals like peroxides, enhance the activity of enzymes like reactive oxygen speciesi  XAn unstable molecule that contains an oxygen atom and in excess can damage cellular components, such as DNA, RNA, and cause cell death. , such as cancer and diabetes. and catalasei  XAn enzyme found in many living things that breaks down hydrogen peroxide into water and oxygen to protect cells from oxidative damage. , and eliminate toxic intermediates, heavy metals, and xenobiotic pollutants.

Simply put, making kombucha a habit may mean saying goodbye to a horde of disorders ranging from acne, pimples, wrinkles, and hair loss to atherosclerosis, kidney failure, cirrhosis, and UTIs.

To get the best antioxidative benefits of kombucha, you can try brewing it with different varieties of tea like green tea, black tea, and lemon balm tea in combination with scoby cultures from various sources.

5. Has Cardioprotective Effects

The antioxidative and antilipidemici  XA medication used to lower the amount of lipids in the bloodstream in cases of hyperlipidemia (too much fat in the blood). activities of kombucha tea boost the levels of good cholesterol (HDL) and reduce the accumulation of bad cholesterol (LDL), along with undesirable free radicals and intermediates, in your blood vessels.

This way, blood pumped to your heart is less polluted, and the blood vessels are less clogged with plaques or cholesterol deposits (5).

When the blood is cleaner, and the blood vessels are dilated, the heart doesn’t have to exert too much pressure to pump the blood in or out of it.

Replacing your tea or coffee with kombucha may protect your heart from diseases like atherosclerosis, myocardial infarction, and hypertension.

6. Manages Inflammatory Diseases

Fermented drinks like kombucha tea can benefit conditions like arthritis, diabetes type 2, asthma, irritable bowel syndrome, certain UTIs, psoriasis, dermatitis, ulcers, GERD, and renal failure that stem out of inflammation.

The 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, downregulate the production of pro-inflammatory chemical messengers like IL-6 and TNF-α and nitric oxide, which can trigger surrounding tissue damage (6).

7. May Prevent And Combat Cancer

Increase in reactive oxygen speciesi  XAn unstable molecule that contains an oxygen atom and in excess can damage cellular components, such as DNA, RNA, and cause cell death. (ROS) is one of the causes that lead to tumor formation in your body.

If left untreated, these ROS (like peroxide and superoxide ions, heavy metal intermediates, and accumulated xenobiotic residues) can support tumor metastasisi  XThe process by which cancer cells migrate from their formation site to other areas and generate new tumors in different parts of the body. , which could be lethal (7).

Kombucha tea can come to your rescue here. It is loaded with the goodness of antioxidants, vitamins, and probiotic microbes that can combat inflammation and decrease ROS effectively.

Kombucha has caffeine derivatives, phenolic acids, polyphenols, terpenes, and vitamins that can scavenge ROS from almost every nook and corner of your body, protect you from inflammation-induced cancer, and also stop its progression and metastasis.

8. Is A Strong Antibacterial Agent

In a study, kombucha tea was found to have antimicrobial activity against a number of pathogenic organisms like Staphylococcus aureus, Shigella sonnei, Escherichia coli, Aeromonas hydrophila, Yersinia enterolytica, Pseudomonas aeruginosa, Enterobacter cloacae, Staphylococcus epidermis, Campylobacter jejuni, Salmonella enteritidis, Salmonella typhimurium, Bacillus cereus, Helicobacter pylori, and Listeria monocytogenes (8).

The scoby produce acetic acid as a by-product of tea fermentation, which is mainly responsible for the antimicrobial activity.

Research claims that there are several compounds in kombucha, other than acetic acid, which have potent antimicrobial activity.

So, drinking kombucha tea can assist in treating bacterial infections like cellulitis, urinary tract infections (UTIs), whooping cough, diphtheria, typhoid, and so on.

9. Promotes Longevity And Wellness

Adding kombucha tea to your diet fosters longevity despite lifestyle changes.

Thanks to the antioxidative, anti-inflammatory, neuro-, cardio- and hepatoprotective phytochemicals, kombucha helps in boosting 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 (9).

protip_icon Did You Know?
Kombucha can also be used to make cloth. If you dry out the SCOBY used for making drinks, what you get is leather-like cloth called microbial cellulose (also called vegan leather by many).

When I tried this recipe, the words that came to my mind were “yum,” “magic,” and “let’s make it again!”

I have been obsessing about this drink for the longest time and must have drunk a few gallons of it.

But there’s something that made me take a step back and ponder over what I was doing.

And that was…

What Are The Side Effects Of Having Kombucha Tea?

I’m sure it must have occurred to you as well that kombucha tea is a ‘fermented’ drink. Although it has only about 0.5% alcohol, prolonged storage could increase the content up to 5%!

Apart from alcohol, drinking kombucha means literally welcoming thousands of microbes into your body. If the kombucha goes bad or is left to ferment too long, the havoc they could create in your body is scary!

Since old kombucha has multiple fatal factors, wouldn’t it be safer to know the risks and side effects associated with kombucha?

So, here we go!

1. Liver Toxicity

Drinking over-fermented, old, and turbid kombucha tea can cause jaundice and other liver diseases. If untreated, it might cause chronic liver inflammation and failure.

This problem could happen as a result of ingestion of high and crude alcohol content that gets generated in kombucha.

2. Acidosis

Since kombucha tea has acetic acid and other derivatives, it is always recommended that you drink it under medical supervision, especially if you have gastritis, recurring ulcers, etc.

Also, drinking aged kombucha can cause severe acidosis in people (high amounts of acid in your body), which, when ignored, can lead to death.

3. Hypersensitivity And Nausea

In some people, the scoby cultures in the kombucha tea can cause a skin allergy.

Sometimes, if you try out a different or fresh batch of scoby culture or a different brand of readymade kombucha tea, it might cause nausea, headache, diarrhea, and neck pain.

If this is the case, try reducing the intake and monitor your condition. If you still notice these symptoms, refrain from drinking kombucha and see a doctor immediately.

4. Might Cause Problems In Diabetic Individuals

Kombucha is not gluten free or low-sugar. It has a good amount of sugar to support the scoby fermentation. It might shoot up your blood glucose levels and cause organ damage if you already have diabetes.

Consult an endocrinologist to first check if you are hyperglycemici  XAn elevated level of blood glucose that is caused by insufficient insulin or an inability to use it correctly. and then follow the recommended dosage or substitutes.

5. Risky If Immunity Is Weak

Certain conditions can lower your immunity – like viral infections (HIV-AIDS) and post-operative trauma.

Since kombucha has a mixture of microbial strains, a weak immunity can give way to chronic bacterial and fungal infections.

If you ignore these symptoms, such infections can be life-threatening.

protip_icon Trivia
Children below 4 years of age are recommended against drinking kombucha tea. Their immune system wouldn’t be able to digest the bacteria and yeast in the tea and they may experience gastrointestinal infections as a result.

6. Pregnancy And Breastfeeding Woes

There is insufficient information regarding the safety of this drink for pregnant and breastfeeding women.

Hence, it is better to stay away from kombucha during this phase of your life to avoid unnecessary complications.
