The Best Chaga Mushroom: Our Picks

Guide: Questions you should ask yourself before buying Chaga mushroom

What is a Chaga mushroom and where does it come from?

The Chaga mushroom, also known as Inonotus obliquus, is a medicinal mushroom that is mainly native to Russia and Scandinavia. But it is also sometimes found in regions such as Central and Eastern Europe, Northern Europe, Japan, Korea or Central Asia. In Germany, however, you will only find it sporadically.

It usually forms a symbiotic relationship with an old birch tree as a parasitic fungus and grows on its trunk for several years. Of course, it does not always have to be a birch, sometimes it also chooses a rowan, an alder, a maple or another tree species.

However, in order to develop its special healing properties, the Chaga mushroom always needs a birch tree. The birch tree secretes a protective agent against it, which it stores inside.

The older the Chaga gets, the more it resembles a black misshapen mass. Of course, it is not poisonous and you can even make a tea from Chaga mushroom.

What is the Chaga mushroom used for?

The Chaga mushroom has been an established remedy in Russian folk medicine for several centuries.

As early as the 12th century, its properties were used to cure diseases and relieve pain. In the meantime, many laboratory tests have been carried out, which confirmed its promising healing power.

Strengthening the immune system

Traditional Chinese Medicine (TCM) is also convinced that Chaga has antioxidant and antibacterial effects.

This means that it helps your body scavenge free radicals and protect itself from viruses and bacteria. This strengthens your immune system and makes you less susceptible to disease.

Hypothyroidism and Hashimoto's disease

The Chaga mushroom also works on the release of stress hormones and thus provides a pleasant balance.

This relieves symptoms of stress, which also has a positive effect on diseases of the thyroid gland. The Chaga mushroom has been shown to improve the symptoms of hypothyroidism and Hashimoto's disease in particular.

Treatment of chronic inflammations

It has also been shown to produce successful results in chronic inflammation of the pancreas.

In folk medicine, Chaga is often used for the treatment of diseases of the gastrointestinal tract as well as irritable bowel syndrome. Especially if you have a sensitive stomach by nature, the Chaga mushroom could do you good.

Treatment with Chaga mushroom for cancer

After numerous tests, researchers are convinced that Chaga mushroom inhibits the growth of cancer cells and can even induce their cell death in some cases. (1)

Studies suggest that the mushroom can have a fighting effect on colon, lung and cervical cancers. The trials also suggest that the Chaga mushroom can exert a cancer-fighting effect through four possible mechanisms:

  • Antioxidation to prevent the development of cancer in the first place
  • Inhibit the growth of tumour cells
  • Killing tumour cells directly
  • Activating the immune system to kill tumour cells (2)

Of course, more detailed research needs to be done here, as the tests have only been done on animals so far. However, the results so far have already brought a lot of hope that we have found a new remedy in the fight against cancer.

Tumour cells from breast and colon cancer were tested. Furthermore, pain-relieving properties were confirmed, which are of great importance in cancer therapy. (3)

Further positive properties

Yes, the Chaga mushroom can do even more. For example, it is not only anti-inflammatory, but also purifies the blood, lowers cholesterol levels and supports organs such as the heart, liver, spleen and lymph.

Chaga has a positive effect on your skin and makes you look younger for longer. By stimulating melanin production, the mushroom also protects your hair from premature greying.

What are the effects of the Chaga mushroom?

So far, more than 200 important vital substances have been identified in the Chaga mushroom. All of these make its extensive healing power possible in their interaction.

Its mineral content is about 15 % and consists of sodium, potassium, manganese, some calcium, iron, silicon, magnesium, chromium, copper and zinc.

Furthermore, the Chaga mushroom also contains organic acids such as formic, oxalic, acetic and vanillic acid. These are responsible for processing the minerals and are also an important component of our entire biochemical metabolism.

The work of the enzymes in your body is also positively influenced and supported by the numerous vital substances of the Chaga mushroom.

For whom is Chaga mushroom suitable?

Basically, Chaga mushroom tea can be drunk by anyone or taken in any other form, as no side effects have been found so far. However, if you have a mushroom allergy, please check with your doctor first!

Furthermore, you should be careful not to take it at the same time as antibiotics and you must also refrain from taking it with intravenous glucose (infusion). However, if symptoms of illness appear, you should stop taking the Chaga mushroom and see a doctor.

The Chaga mushroom is generally very well tolerated and therefore also suitable for pregnant women, children or even pets. Otherwise, don't forget that the Chaga mushroom can help you, but cannot replace a healthy diet.

How should Chaga mushroom be dosed and taken?

Ideally, Chaga mushroom should be taken as a tea. It is sufficient to add 2-3 teaspoons of the powder to 300 ml of hot water. If you prefer Chaga mushroom chunks, you will find instructions for the correct preparation in the Trivia.

You should drink the tea as a cure for at least three months, preferably two cups daily. It is recommended to integrate it into your daily routine and diet.

Chaga tea is most effective on an empty stomach. So, for example, you could drink the first cup first thing in the morning, before you have breakfast. Chaga mushroom tea can also be a healthy alternative to coffee.

If you like, you can also refine dishes with the Chaga mushroom. Otherwise, you can also add some to a hot bath to nourish the skin and inhale the mushroom. To treat skin diseases in young children, 50-100 ml of Chaga tea is enough.

What alternatives are there to Chaga mushroom?

There is currently no comparable product to the Chaga mushroom, as its versatile healing power makes it a real gem in folk medicine. Chaga mushroom alone can provide relief from several ailments and has a pain-relieving and anti-inflammatory effect.

If you only have one particular problem, you may find an alternative. Of course, this depends on what exactly you want to treat and whether there is anything available.

Decision: What types of Chaga mushroom products are there and which one is right for you?

Basically, you can distinguish between two types of Chaga mushrooms:

  • Wild traditional Chaga mushroom
  • Cultivated Chaga Mushroom

The following sections explain the respective advantages and disadvantages of the different Chaga mushrooms.

What distinguishes wild traditional Chaga mushroom and what are its advantages and disadvantages?

The real Chaga mushroom, which also has this promising effect, always comes from a wild collection. It grows in very cold regions, where the Chaga mushroom defies temperatures of up to minus 40 degrees. Only under these conditions can it form its vital substances and develop healing powers.

Furthermore, it must grow on a birch tree and on no other tree to be medicinally valuable. When these conditions are met, the medicinal mushroom has the highest ORAC value of all natural foods. The ORAC value indicates the antioxidant activity of a food.

Antioxidants are enzymes and nutrients that protect your body from the attacks of free radicals. The higher the value, the greater the positive effect on your well-being.

Free radicals also cause so-called oxidative stress. This accelerates the ageing process in your cells and blood vessels. As a result, oxidative stress forms the basis for many health problems.

  • Can be used as a medicinal mushroom for many diseases
  • Highest ORAC value of all natural foods
  • Has the highest quality
  • Very expensive
  • Wild Chaga mushroom grows very slowly
  • Must meet certain requirements

What distinguishes cultivated Chaga mushroom and what are its advantages and disadvantages?

If you have already read through the above, you now know that artificially cultivated Chaga mushroom is usually not of good quality at all. Most of them are low-quality, cheap imports from suppliers who just want to make a profit with the supposed medicinal mushroom.

Labels such as "organic" or "from Finnish/Siberian wild collection" on the product do not change anything.

These suppliers often know very little about their Chaga mushroom product and cannot give good advice because they do not consume it themselves. So if you plan to buy Chaga mushroom, better spend more money on good quality or do without it completely before you damage your health.

  • Very cheap
  • Mostly inferior quality
  • Misleading names
  • Dubious suppliers
  • Poses health risks

Buying criteria: Use these factors to compare and evaluate Chaga mushroom products

In order to buy the right Chaga mushroom product, there are some criteria to consider. The following purchase criteria should be considered before buying:

  • Type of Chaga Mushroom
  • Country of origin
  • Tree species and age
  • Age of the mushroom
  • Method of harvesting
  • Drying and storage
  • Type of packaging during shipping
  • Quality

The following sections explain each of the buying criteria in more detail and show exactly what you should look for.

Type of Chaga mushroom

You should always prefer Chaga from a wild collection to be on the safe side. There are certificates for this on the homepage or you can contact the seller. Otherwise, you should always read the reviews and compare what other people have already experienced with the product.

If you are still unsure, you can research other places on the internet about the seller.

It is best to buy the Chaga mushroom in chunks, which is also in keeping with tradition. The powder often provides a target for mould and bacteria if it is poorly packaged. Cheap imports may contain substances that are harmful to health, among other things, in the powder. Tablets or capsules are also not always recommended.

Country of origin

Traditionally, the Chaga mushroom comes from very cold regions, especially Lapland. Lapland is an area in the far north of Europe that stretches across Norway, Sweden, Finland and Russia. The subpolar climate is characteristic.

Tree species and age

In order for the Chaga mushroom to actually become an effective vital mushroom, it always needs an old birch tree for symbiosis. Its age should be between 20 and 70 years, at best not too young and not too old. The fungus extracts important substances from the birch tree, which it secretes as protection against it. It also absorbs and stores the valuable birch sap.

It is also important that the Chaga mushroom grows at a height of at least one metre on the tree. It should not draw water from the soil and should not grow too close to the roots.

Age of the mushroom

The Chaga mushroom, or slate fungus, can live between 10 and 20 years. This also depends on how long it takes for the host tree to die. To be able to harvest it, it should be at least five years old.

An important criterion for harvesting the Chaga mushroom is its age. It should be at least five years old before it is harvested. (Picture source: / Olga Vorobeva)

How to harvest

The mushroom must be cut manually and never with a chainsaw or similar tools.

Drying and storage

In order to avoid mould, the Chaga mushroom must be gently dried over several days until its residual moisture is only a maximum of 15%. If you want to be absolutely sure that the mushroom will not mould, you can buy dry granules.

Type of packaging for shipping

As the mushroom could easily start to mould, make sure that it is not packed in plastic or aluminium bags. If you buy inferior quality, it is quite possible that it will arrive at your home packed in this way.


Quality is the be-all and end-all of Chaga mushrooms. Therefore, you should avoid farm products (cultivated Chaga). This also does not contain the valuable ingredients of birch, because it has been cultivated on algae. It is therefore of no value for your health. Pesticides and fertilisers are often used to make it grow faster.

When the Chaga mushroom is ground into powder after harvesting, it naturally also contains these harmful substances.

Interesting facts about Chaga mushrooms

How do you prepare a Chaga mushroom tea correctly?

You will see that the preparation is really easy.

  • Take three medium sized chunks of the Chaga mushroom
  • Simmer them in 500 ml of water for about 10 minutes
  • Wait until the water turns a brownish colour
  • Strain the tea and pour it into a cup
  • It is then ready to drink

You can put the remaining chunks in a glass jar with water and then cover it and put it in the fridge. You can reuse them as often as you like until they no longer give off any colour. The water in which you store the chunks can then be used again for your next tea. Granules are also very suitable for this method. You can usually use this for up to three infusions.

You can also adjust the amount and use less pieces and water for your tea. The more water you use, the lighter the Chaga mushroom tea will be. If you want it stronger, simmer it longer or use less water.

The taste of the tea reminds many of black tea without milk and sugar. If you don't like it that way, you can mix it with other teas such as peppermint or camomile. If it is too bitter for you, you can sweeten it with a little honey.

The Finns mix their Chaga mushroom tea with coffee and drink it as "Chaga coffee". This drink has a performance-enhancing effect and the vital substances of the mushroom are absorbed even faster by the blood due to the caffeine. However, this combination is not for everyone. If you are ill, you can also add some ginger to the Chaga tea.
