Kombucha is a living drink made by fermenting tea and sugar with the “kombucha” culture. The result can taste like something between sparkling apple cider and champagne, depending on what kind of tea you use.
The origins of Kombucha aren’t exact. It is thought to have originated in the Far East, probably China, and has been consumed there for at least two thousand years. The first recorded use of kombucha comes from China in 221 BC during the Tsin Dynasty. It was known as “The Tea of Immortality”.
It has been used in Eastern Europe, Russia and Japan for several centuries. It’s from Japan in 415 AD that the name kombucha is said to have come. A Korean physician called Kombu or Kambu treated the Emperor Inyko with the tea and it took his name, “Kombu” and “cha” meaning tea. Russia has a long tradition of using a healing drink called “Tea Kvass” made from a “Japanese Mushroom”.
From Russia it spread to Prussia, Poland, Germany and Denmark but it seems to have died out during World War Two. After the war Dr Rudolph Skelnar created renewed interest in kombucha in Germany when he used it in his practice to treat cancer patients, metabolic disorders, high blood pressure and diabetes.
The Kombucha Culture
The Kombucha culture looks like a beige or white and pancake shaped. It’s often called a ‘scoby’ which stands for ‘ symbiotic culture of bacteria and yeasts.The culture is placed in sweetened black or green tea and turns a bowl full of sweet tea into a bowl full of vitamins, minerals, enzymes and health-giving organic acids.
As the Kombucha culture digests the sugar it produces a range of organic acids like glucuronic acid, gluconic acid, lactic acid, acetic acid, butyric acid, malic acid and usnic acid; vitamins, particularly B vitamins and vitamin C; as well as amino acids, enzymes. And of course there are all the benefits of the probiotic microorganisms themselves. The Kombucha culture is a biochemical powerhouse in your kitchen.
You might wonder if fermenting tea with yeasts would produce an alcoholic beverage. It’s a good question. The yeasts do produce alcohol but the bacteria in the culture turn the alcohol to organic acids. Only minute quantities of alcohol, typically 1% by volume remains in the kombucha brew.
With every brew you make the kombucha forms a new layer or scoby on the surface of the liquid. These can be left to thicken the scoby or can be divided, giving you spare cultures that you can store in some sweet tea in the fridge in case something should happen to your active culture. Or you might want to pass on spare Kombucha cultures to friends or use a new scoby to start another batch of kombucha.
Kombucha and Health
Many health claims are made for kombucha but there is less research on the benefits of kombucha than there is on fermented milk products. It has certainly been shown to have similar antibiotic, antiviral and anti fungal properties in lab tests. In rats it’s been shown to protect against stress and improve liver function. There is a lot of experiential evidence from people who have been using kombucha over many years. Many of the benefits reported include improvements in energy levels, metabolic disorders, allergies, cancer, digestive problems, candidiasis, hypertension, HIV, chronic fatigue and arthritis. It ‘s also used externally for skin problems and as a hair wash among other things.
The Organic Acids
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.
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
