5/5 - (1 vote)

Although it is not known for certain where kombucha originated, there are many sources that attribute its first use to the regions of China. There are even several versions of why it has that name. The truth is that kombucha has been used for hundreds of years, taking advantage of its properties.

Knowing these characteristics, the benefits it produces as well as the risks, if any, when using it is of great importance. Let’s review these points.

What is kombucha?

Kombucha is directly related to a group of bacteria, and is used to prepare infusions. It is also known as mushroom tea or manchurian mushroom. However, it is actually a colony of bacteria

The preparation of this tea requires a series of steps, which allow to have a drink full of many properties that promote good health.

Among the key steps for its preparation we can point out the following:

  • Cleaning. The mushroom should be washed well before adding it to the tea, which will usually be red. Although green or black can also be used.
  • Temperature. It is necessary that the tea does not exceed 35° to prevent fermentation from being affected.
  • Container. As it is a group of bacteria, some chemical processes occur during fermentation. For this reason, metal or ceramic containers should not be used.

The people of China were firmly convinced that kombucha was a divine gift. For this reason, its commercialization was slow to appear in the world, as it was considered disrespectful to make a profit with this product.


Properties of kombucha

The use of kombucha has spread to many parts of the world thanks to the properties attributed to it. Studies carried out by different doctors in different countries point out the following.


It contains medusomycetin, a substance of proven effectiveness in the recovery of patients with diphtheritia, dysentery and paratifus A and B. This information was verified by studies carried out at the Institute of Epidemiology of Kazakhstan.


Two Indonesian professors of medicine made several evaluations, using leaves, which proved that kombucha prevents and repairs the effect of free radicals on the skin. This is due to the abundant presence of polyphenols. These also contribute to de-inflammation of the body.

In addition, it contains glucuronic acid, which is a recognized detoxifier, used to cleanse the body of harmful substances.


Kombucha prevents the appearance of bacteria that can harm the organism. This is due to the fact that, after fermenting, it appears on the scene the acetic acid. Experts assure that the effect of this component increases when the infusion is prepared with black or green tea.

Another of the positive properties of kombucha is that it has very few calories. This is beneficial for everyone, especially for those who keep a strict control of their daily calorie intake.

Benefits of kombucha

Since it has a wide variety of properties, it has been used for many years. Here are some of the benefits enjoyed by those who consume kombucha.

Improves intestinal flora

Kombucha possesses a large amount of acids, which are activated as it goes through the fermentation process. In addition, it has many probiotics. Thanks to the effect of these elements, the intestinal flora is benefited by strengthening the bacteria that regulate its functioning.

Protects the cardiovascular system

Since kombucha has several beneficial components for the organism, and it is also prepared using tea, it contributes to the considerable decrease of LDL, known as bad cholesterol. Hence, it protects the heart and the rest of the organs that interact with it.

It takes care of the liver and kidneys

Kombucha positively affects the production of liver enzymes, responsible for the proper functioning of the kidneys and liver. Thanks to this, it is easier for these organs to eliminate any harmful elements. All this contributes to good health.

Strengthens the body’s defenses

One of the benefits of kombucha tea, due to its yeast content, is the increase of the body’s defenses. Thanks to its consumption, the body is better prepared to deal with the appearance of viruses and bacteria.

are there any risks in using kombucha?

Although it is a drink that does not contain any chemically processed elements, there are some risks when consuming it. This is because the preparation of the infusion is not always carried out taking into account the appropriate sanitary measures. In other cases, the risks are due to excessive consumption of kombucha.

In addition, although many studies have been conducted over time, many evaluations are still lacking, especially using people, to clearly determine the true risks and benefits of this colony of bacteria, which directly influences the infusion.

In this sense, the same magazine points out the opinion of some health experts on the consumption of kombucha. On the one hand, some affirm that it is beneficial for the body, because it has many medicinal properties, which have been proven in different studies.


While other health specialists contradict this claim. They claim that the risks associated with kombucha consumption are greater than its benefits. But, as we have already mentioned, these discrepancies are due to the lack of more conclusive studies.

Throughout Europe, kombucha continues to be distributed for consumption, which is approved by both governments and health agencies. The recommendations given by these institutions to avoid negative effects are twofold. First, to avoid its consumption in large quantities and, second, to take the utmost care in its preparation.

The truth is that for hundreds of years kombucha has been an excellent and beneficial drink for millions of people. And it will surely continue to be so for a long time to come.
