Health Benefits of drinking Kombucha
Kombucha promotes healthy digestion. Attributing to the process of fermentation with a live colony of bacteria and yeast, it works as a probiotic by helping in sustaining the gut health and provides relief from various abdominal disorders including chronic constipation and diarrhea symptoms. The digestive enzymes present in it enhance the effects of glucuronic acid and aid in the breakdown of proteins and saccharides thereby, making the digestive system more efficient.
Kombucha possesses antibiotic properties i.e. bacteriocidal and bacteriostatic which works against a range of pathogens and is used for therapeutic purposes in human as well as veterinary treatments.
Detoxifies the Body
Kombucha may have a remarkable ability to detoxify the body. It contains a powerful detoxifier glucuronic acid which binds the toxins by entering the liver and eliminates them out of the body via kidneys.
Kombucha contains profuse amounts of organic acids like glucuronic acid and powerful antioxidants which may help in shielding the body from oxidative damage. The antioxidants present in it look out for the oxygen free radicals and neutralize their effects thereby, repairing and protecting the body from diseases and inflammations.
Another suggested healing action purported by kombucha is its hepatic-protective effects. A research study conducted on kombucha has shown that its tea helps in restoring the levels of glutathione and is remarkably effectual in reducing the induced hepatotoxicity. A comparative study conducted on black tea, kombucha tea, and enzyme-processed black tea has proven the efficacy and superiority of kombucha tea in providing hepatic protection against the toxicity attributing to its antioxidant power as compared to the latter.
Possible Anti-microbial Effects
Kombucha tea has anti-microbial properties which may prove effective against a variety of pathogens. An investigative research has revealed that apart from acetic acid, it contains other anti-microbial components which even at neutral values of pH provide protection against a range of microorganisms including Staphylococcus aureaus, Staphylococcus epidermis, Escherichia Coli, Salmonella enteriditis, Pseudomonas aeruginosa, Listeria monocytogens, and Helicobacter pylori
The specific bacteria and yeast strains in the kombucha are what make it act the way it does, and what produces the fizz and flavor of kombucha. Not all kombucha cultures will contain the exact same strains, but these are some that have been recorded in studies:
Acetobacter  is an aerobic (requiring oxygen) bacteria strain that produces acetic acid and gluconic acid. It is always found in kombucha. Acetobacter strains also build the scoby mushroom. Acetobacter xylinoides and acetobacter ketogenum are two strains that you might find in kombucha.
Saccharomyces  includes a number of yeast strains that produce alcohol and are the most common types of yeast found in kombucha. They can be aerobic or anaerobic (requires an oxygen-free environment). They include Saccharomycodes ludwigii, Saccharomycodes apiculatus, Schizosaccharomyces pombe, Zygosaccharomyes, and Saccharomyces cerevisiae.
Brettanomyces  is another type of yeast strain, either aerobic or anaerobic, that are commonly found in kombucha and produce alcohol or acetic acid.
Lactobacillus : A type of aerobic bacteria that is sometimes, but not always, found in kombucha. It produces lactic acid and slime.
Pediococcus : These anaerobic bacteria produce lactic acid and slime. They are sometimes, but not always, found in kombucha.
Gluconacetobacter kombuchae  is an anaerobic bacteria that is unique to kombucha. It feeds on nitrogen that is found in tea and produces acetic acid and gluconic acid, as well as building the scoby.
Zygosaccharomyces kombuchaensis  is a yeast strain that is unique to kombucha. It produces alcohol and carbonation as well as contributing to the mushroom body.
The body’s most important detoxifier. When toxins enter the liver this acid binds them to it and flushes them out through the kidneys. Once bound by glucuronic acid toxins cannot escape. A product of the oxidation process of glucose, glucuronic acid is one of the more significant constituents of Kombucha. As a detoxifying agent it’s one of the few agents that can cope with pollution from the products of the petroleum industry, including all the plastics, herbicides, pesticides and resins. It kidnaps the phenols in the liver, which are then eliminated easily by the kidneys. Kombucha can be very helpful for allergy sufferers. Another by-product of glucuronic acid are the glucosamines, the structures associated with cartilage, collagen and the fluids which lubricate the joints. It is this function that makes Kombucha so effective against arthritis.
Glucuronolactone, glucuronic acid is involved in the metabolism of detoxification in the liver whose glucuronyl rest of the body is linked to a group of foreign compounds or any of the metabolites in the body so that they become soluble in water and are excreted in the urine. Glucuronic acid should be distinguished from gluconic acid because it is linear and the gluconic acid is formed by oxidation of the different carbon glucose atom.
Essential for the digestive system. Assist blood circulation, helps prevent bowel decay and constipation. Aids in balancing acids and alkaline in the body and believed to help in the prevention of cancer by helping to regulate blood pH levels.
A powerful preservative and it inhibits harmful bacteria.
A natural antibiotic that can be effective against many viruses.
An effective preservative and encourages the intercellular production of energy.
Helps detoxify the liver.
Produced by the bacteria, it can break down to caprylic acid is of great benefit to sufferers of candidiasis and other yeast infections such as thrush.
Produced by the yeast, protects human cellular membranes and combined with Gluconic acid strengthens the walls of the gut to combat yeast infections like candida.
Kombucha also contains a variety of other nutrients, particularly various acids and esters that give the drink its characteristic tang and fizz. Included in these components is gluconic acid, which is the primary difference between the makeup of kombucha and the makeup of apple cider vinegar.
Flavonoids are part of a large class of chemicals called polyphenols that occur naturally in plants. Flavonoids, which are found in a variety of fruits and vegetables as well as in tea and red wine, are thought to boost health in part by combating oxidation. That’s why they’re called antioxidants. Antioxidants help the body’s cells resist damage by free radicals. Tea has one of the highest total flavonoid contents of all plants at 15% of the leaf by dry weight and is the major source of flavonoids in the UK diet, providing approximately 80% of dietary flavonoids for the population as a whole.
So don’t stop drinking your tea!
The actual bacteria, sugar, and acid content of kombucha depend on many factors, including the initial culture, the type of tea used, the type of sugar used, the strength of the tea, the type of water, the brewing time, the culturing temperature, and more. Due to the nature of kombucha, it is not possible to state an exact microbial composition for Kombucha. 
While different SCOBYs may vary in their exact makeup, what is common to all kombuchas is gluconic acid, acetic acid, and fructose.
