Chaga Mushroom: Benefits, Uses, and Recipes

King of Medicinal Mushrooms

Chaga is an extraordinary functional mushroom that grows primarily on birch trees and has been used since the 12th century for its medicinal compounds. It is well known for its antimicrobial, antiviral, and antitumor activity. 1, 2 I’m really excited to share what I’ve discovered about this “King of Medicinal Mushrooms” with the intention that you will learn how to enjoy the benefits of this amazing adaptogen for yourself!

What is Chaga Mushroom?

Chaga (Inonotus obliquus), is a fungusand the Chaga “mushroom” is not technically a mushroom but a sclerotium (a mass of Chaga mycelium and wood from the tree that it grows on). Mushrooms are the fruiting bodies of fungi. Chaga does have a fruiting body, but for most of its life it grows underneath the bark of the host tree and is rarely seen.

A pathogen to the birch tree, the spores of the Chaga fungus typically infect the tree through its weak spots like wounds and dead branches.
Once the fungus takes hold, it causes the center of the tree trunks and branches to start to rot. The fungus spreads inside and grows toward the outside of the tree until it eventually bursts through the bark and a burnt charcoal-looking mass (a “conk”) appears. The conk will continue to grow on the tree’s trunk as the inside of the tree continues to decay. This can go on for ten, twenty, or even eighty or more years.
As the conk grows, the medicinal compounds of the birch tree become concentrated in the Chaga mass. 3, 4

Because the tree can live for a long time after being infected with the fungus, some people believe that the relationship between Chaga and the birch is symbiotic in nature. While this is a nice theory, I have not found any scientific evidence to support this idea.

Health Benefits of Chaga Mushroom Extract

Chaga has been used for centuries to help improve the body’s response to stress, boost immunity, reduce inflammation, promote healthy skin and hair, fight and prevent cancer, and as a remedy for many other ailments.


In its true adaptogenic style, Chaga has a way of balancing inflammation, allowing the “good” inflammatory responses to occur while preventing the “bad” inflammation from developing. 5, 6


Chaga has long been used in folk medicine for cancer treatment in Russia, China, Korea and Japan. Studies show that Chaga contains large amounts of betulin or betulinic acid, a compound that has anti-cancer properties. In other scientific studies, Chaga extract demonstrated antimitotic activity on human cancer cells, as well as reduction of tumor growth, which could be useful in stopping the spread of cancer. 7, 8, 9


Chaga is rich in polysaccharides, especially beta-glucans, which are responsible for stimulating the immune system by activating adaptive immune cell responses. 10, 11


Chaga mushrooms have a powerful enzymatic system and a strong system of defense, due to their parasitic mode of life. Insight into the connection between Chaga mushroom and its antiviral effect has proven to be promising. Some studies show that Chaga extract fights against viruses, including herpes, hepatitis C, and HIV. In other studies, Chaga extract prevented infection by blocking viruses from attaching to cells. 12, 13


Antioxidants molecules that work to neutralize free radicals (unstable atoms that can damage cells) in our bodies. These free radicals can contribute to heart disease, cancer and other illnesses, and keeping high levels of antioxidants in our bodies helps to keep us healthy and balanced.
Surprisingly, Chaga is loaded with more antioxidants than berries! Many people use Chaga for anti-aging and to help promote healthy skin and hair. 14

“The study also found that Chaga has 3 times more antioxidant power than the next strongest food of any kind (wolf berry). So according to the study, Chaga is the #1 best antioxidant source in existence. Additionally, Chaga provides 19 of the 20 amino acids required by humans, making it a valuable supplement for vegetarians and vegans.” — University Health News

While some scientific studies indicate that Chaga extract may provide these health benefits, there is definitely a need for clinical trials to help determine dosage and potential side effects. Most people do well at the recommended supplemental doses, however, as with any type of new food or supplement, start with a small amount to make sure that you are not allergic. You should also talk with your doctor before adding any new supplements to your diet, especially if you are on medication.

Where To Find Chaga Mushrooms

Chaga grows mainly on birch trees in the northern climatic zones, including the northern United States, Canada, Russia, and northern China.

Last month I had the awesome opportunity to go Chaga hunting in the forests of Vermont with an amazing bunch of people. It was definitely an adventure, and let’s just say I have some new campfire story material!

I learned that the best way to locate Chaga is to find a stand of birch trees. Then, look high and low for a black clump that looks like burnt charcoal. It will have a cork-like, golden-colored inside. Full grown Chaga usually averages around 15 to 20 inches in size. The first Chaga mushroom we found on our trip was too small. Check out the short video below where Josh, (our forage leader and founder at Life Itself), explains what we should be looking for.
