With plenty of articles out there touting the magic of chaga, we decided to focus on many of the unknown aspects or myths about it. What is Chaga? It is a very unique parasitic fungus, which is much different from the other mushrooms you know and love.

In the late 1990′s Chaga was virtually unknown as a dietary supplement, with the exception of Russia and a few countries in Southeast Asia. Now, in today’s world, many circles highly regard Chaga as a potent superfood.So let’s jump right in and reveal 

9 Things You Didn't Know About Chaga

If you'd prefer to get your Chaga facts from the mouth of Real Mushrooms' Chief Funguy, Skye Chilton, take a look at the video below:

1. Chaga is not a mushroom

So, what exactly is Chaga, you ask?

Chaga is the common name for a perennial canker or sterile conk that commonly forms on a birch tree (Betula papyrifera, paper birch) after it has been infected and colonized by the mycelia of the pathogenic fungus Inonotus obliquus. The part of this fungus that one harvests is the outward manifestation of the fungal disease.

Common names for chaga include clinker polypore, cinder conk or birch canker polypore (not to be confused with birch polypore - Fomitopsis betulina). In British Columbia, Inonotus obliquus is classified as a tree disease.

How Chaga Grows:

The spores have penetrated the birch tree, germinated, and have begun to consume the heartwood. The fungus will then push toward the exterior of the tree consuming the wood as it goes. The fungus will break through the bark and begin to form the canker of mycelium and wood lignins we call "Chaga." Over many years, the Chaga grows much bigger and darker. It largely contains wood fiber & lignin which house many of the nutrients found in the host tree.

What we call ‘Chaga’ is the dense black mass that can be seen on the exterior of trees (almost exclusively on birch) infected with the fungus Inonotus obliquus. It's not a mushroom (fruiting body) but a dense sterile mass of decayed bits of birch tissue with mycelia incorporated.

When chopped from the tree the interior has a rusty yellow-brown color, somewhat granular in appearance, and is often mottled with whitish or cream-colored veins. Chaga can be referred to as a sclerotium, which is a dense mass of mycelium, but this is technically incorrect as Chaga is not pure mycelium.

One research paper estimated Chaga to be only around 10% mycelium based on microscopic observation. A more accurate term for Chaga is conk or canker or just plain old Chaga.

The exterior canker that is harvested should not be confused with the actual fertile fruiting body, which normally forms under the partially detached bark on dead standing or fallen trees. This fruiting body is a greyish, flat thin layered mass, up to 3-4 meters long and 40-50 cm wide, with downward cascading pores, which are the spore-producing layer of polypore fungi.

2. Chaga is primarily wood fiber and contains Birch compounds

Chaga is a slow-growing fungus that primarily grows on birch trees. It is common to find Chaga in the boreal forest regions of the Northern Hemisphere like in Russia, Korea, Eastern and Northern Europe, Northern areas of the United States and Alaska, Canada, and Northern China.

Typically, one finds well-developed Chaga sclerotia on trees over 40 years of age, but the infection starts earlier. The period from initial infection to tree death varies with the number of infection sites and tree resistance but is typically around 20 years. After about 3-5 years of growth, the Chaga can be harvested.

The harvested dark black conk consists primarily of wood lignans from the host tree and mycelium of the invasive fungus. Due to this, when Chaga grows on birch, it will also contain birch compounds like betulin and betulinic acid

After harvesting, Chaga can regrow to harvestable size again in three to ten years, and this can be repeated until the tree dies. Chopping off the Chaga does not kill the organism and the mycelium is still inside the tree slowly consuming it. Chaga is not technically a perennial by definition; it may live for years as it consumes its food source, but once that source is exhausted, it will then die for lack of nutrients.

3. Chaga has been used since the 16th century!

Russians have known about Chaga’s health benefits for a long time; the word ‘Chaga‘ is a derivative from ‘чага‘, which is the old Russian word for mushroom. A healing plant of renowned value throughout the world, Chaga is thought to be a potent immune-stimulating medicinal mushroom.

In fact, the first verifiable mentions of Chaga were from the early 16th century. Chaga is documented in folk and botanical medicine throughout Eastern Europe. Traditionally Chaga was used as a common remedy for stomach ailments.¹

Chaga became popular in the West after it was mentioned in the book, Cancer Ward, by Nobel Prize-winning Russian author Aleksandr Solzhenitsyn. In the book, he notes that poorer people saved money on tea by brewing Chaga.

As early as 1955, a Chaga extract known as Befungin (Russian translation) has been sold in Russia to treat stomach and intestinal ailments.

4. Chaga's outer crust contains melanin.

Chaga also contains melanin, concentrated in the black outer crust, which is a complex compound that gives the skin, hair and the iris (colored part of the eye) their color. Our skin naturally darkens in response to sun exposure which stimulates melanocytes to produce melanin. Considered a potent source of melanin, Chaga may help protect the skin and hair from sun damage. Melanins have a role in DNA repair, mitochondria health, cell metabolism, and protection from light and radiation. In particular, melanins from mushrooms exhibit a high anti-inflammatory effect based on their antioxidant and gene-protecting properties. Melanins can decrease oxidation of fatty acids and damage of membranes creating lots of potential for skin health.

5. Chaga was a Finnish coffee substitute in WW2

Often, Chaga is compared to coffee with its robust flavor and dark color. It’s earthy, slightly bitter, and has a small hint of forest sweetness. Luckily, if you are sensitive to caffeine Chaga is a great alternative to coffee as it’s caffeine-free so it won’t keep you awake and it’s just as tasty!

In Finland, during WW2 there was a coffee shortage and substitutes started popping up, many based on roasted rye³. It was then that Chaga emerged as an ideal coffee substitute known as Tikka Te.

Chaga Coffee (which is really more like a tea) is a great and simple way to consume Chaga. You can buy the wild chunks from a reputable source to brew your own magical concoction.

But if you’re just looking for a quick and easy way to add Chaga to your diet, we’ve made it simpler for you to consume with our amazing Chaga capsules. We use a hot water extraction made from our pure source of wild-harvested Chaga from Siberia. Take two of these capsules daily over a three month period to feel the full health benefits.

6. Chaga Harvesting is Sustainable!

Many argue that wild harvesting of Chaga is not sustainable and we need to be wary of overconsumption of this fungi.

In 2004, David Pilz, Forestry Mycologist at Oregon State University, went to Russia to report on whether Chaga harvesting in Russia was sustainable or not.⁵ This is the most detailed report of Chaga harvesting currently available. The report determined that the “biological Chaga resource is immense, and unlikely to be over-harvested to the detriment of the species Inonotus obliquus any time in the near future.” According to the report, Chaga is excessively abundant, even with over-harvesting estimates.

The report states that Chaga infects upwards of 20% of all birch trees in Russia. This is in stark contrast to some claims on the internet that Chaga is extremely rare and only found on 1 in every 10,000-20,000 birch trees.

Similar to Russia, Scandinavia has vast boreal forests. Luke, The Natural Resources Institute Finland, estimates that Chaga infects 6-30% of all birch in Sweden and Finland.

Given similar estimates between Russia, Finland, and Sweden, it would be safe to assume that Canada also has vast amounts of Chaga in its boreal forest regions.

The Pilz report did make an important note about proximity to chaga. While the resource is vastly abundant, how far harvesters need to travel in order to find chaga will have a direct impact on the selling price. Popular harvesting areas may get over-harvested and lead people to believe that this fungus is threatened.

The Future of Chaga

In the future, there may be a tipping point at which the cost of harvesting becomes too expensive for supplements but given the vast amounts of Chaga available, this turning point would be well before there was any threat to the species itself.

An important note is that harvesting Chaga does not kill the organism itself. The mycelium is still inside the tree slowly consuming it. Near or after the tree’s death, the mycelium will begin to produce the mushroom (fruiting body) so that spores can be released and the organism can reproduce. Chaga harvesting does not impact the organism's ability to reproduce.

7. We rarely see the Chaga “Mushroom”

Since the harvested part of the Chaga is actually a woody canker and not a mushroom in the traditional sense, it begs the question: Does Chaga have a fruiting body?

Yes, it does but we rarely see it.

The actual mushroom (fruiting body) forms under the bark on dead standing or fallen trees. After the tree dies, the bark slowly separates from the tree, revealing the sporocarp (fruiting body). This fruiting body is a greyish, flat thin layered porous mass with downward cascading pores. When the conditions are correct, the pore layer will begin to release spores which will get blown around in the wind and eventually end up on a weakened birch tree and the infection process will start over. Insects also like to eat the mushroom which helps to transport the spores to new areas.

8. Lab grown Chaga is not Chaga!

Cultivated Chaga can and will have a different composition and therapeutic properties, depending on the conditions under which it grows (different types of substrate, environmental conditions, etc.)

This is because a lab can only cultivate the mycelium and not cultivate the canker or sclerotium itself.

Wild Chaga takes three to five years before it can be harvested and many of the special compounds in Chaga, like betulin and betulinic acid, come from the birch tree. If no birch tree is involved, like a lab-grown process, then none of these important birch compounds will be present. No black outer layer, no melanin. Not to mention that lab-grown Chaga is myceliated grain so there will be a large concentration of grain in the final product as opposed to the actual Chaga canker.

Luckily, our Siberian Chaga is wild-harvested and tested by 3rd party laboratories for the active compounds like beta-D-glucans that are quintessential nutrients for the immune system. This wild Chaga has been maturing for upwards of 20 years in the cold and wild boreal forests. Siberian Chaga contains many polysaccharides, triterpenoids, and melanin which is a pigment we need throughout the human body.

We care deeply about sourcing the highest quality mushrooms that contain the most medicinal compounds to support your health over long term use. It is recommended that adults take two capsules of our organic Chaga daily.

9. Chaga can be used to start fires

The bushcraft and survivalist communities use Chaga as a fire starter. Once dried, the inner brown section of chaga can take a spark and it is very slow burning making it ideal as starting coal for your fire. Fire pistons, which compresses air to create heat to ignite your starting coal, can also make use of Chaga.
