Chaga Mushroom: A Complete Guide

As mycologists and lovers of all things related to fungi, we are thrilled to delve into the captivating world of Chaga Mushroom – a unique, nutrient-rich, and fascinating fungus found on birch trees in northern climates. 

This mushroom is a unique, nutrient-rich, and fascinating fungus found on birch trees in northern climates. It offers impressive health benefits. One of the reasons it’s so good for you is its high ORAC score, which stands for “oxygen radical absorbent capacity.”

The higher the ORAC value, the better the food can protect your body from disease-causing free radicals[1]. Chaga mushrooms are among the best sources of antioxidants.

So, why do people want to add chaga mushrooms to their diets? Well, it’s because of the numerous potential benefits it offers. People have turned to these mushrooms for various health concerns, including heart disease, diabetes, liver disease, parasites, stomach pain, and certain types of cancer.

Let’s delve into the exciting potential benefits of Chaga and understand why disease-fighting mushrooms are creating such a buzz these days.

What is The Chaga Mushroom?

The Chaga mushroom (Inonotus obliquus) draws nutrients from the host birch tree, sustaining itself through a slow-growing fungus. It boasts several other names, including black mass, clinker polypore, birch canker polypore, cinder conk, and the sterile conk trunk rot of birch. Unlike traditional mushrooms, they have a bitter yet vanilla taste, alongside being high in fiber and low in calories.

This unique growth process enables the accumulation of an array of beneficial compounds, turning it into a powerhouse of nutrients and bioactive substances. Chaga has been utilized to treat diabetes, certain cancers, and heart disease.

Traditionally, people grated chaga into a fine powder and brewed it as herbal tea[2]. Nowadays, you can find chaga not only as tea but also in the form of powdered, or capsuled supplements, or even gummies.

Chaga Identification

Chaga mushrooms were found growing on tree

These mushrooms are easy to identify due to their distinct appearance. So, what do chaga mushrooms look like? They have a lumpy texture with an exterior resembling burnt charcoal, while their core is softer and squishy with a yellow-orange hue.

This fascinating mushroom forms a woody growth called a conk, resembling a clump of burnt charcoal, and measures around 10 to 15 inches (25 to 38 centimeters) in size. However, once you crack it open, you’ll discover a soft, orange-colored core.

When they grow on birch trees, they make quite a sight. Resembling burnt wood, they often cluster together, sometimes growing as large as a human head.

To get the benefits of Chaga, like other medicinal fungi, hot water or alcohol is used to break down their tough cellular walls. This process allows the beneficial properties of the mushroom to be readily available for human use.


For centuries, Chaga mushrooms have been a vital part of traditional medicine. Historical records suggest their use dates back to ancient cultures in Europe and Asia, where they were believed to have healing properties for various ailments. In modern times, studies have found that they contain a variety of beneficial compounds such as polysaccharides, antioxidants, and triterpenes that may have anti-inflammatory, anti-cancer, and anti-microbial properties[3].

Cultivation of these mushrooms has since become widespread in countries like China, Russia, and Korea, and their medicinal benefits continue to be explored.

What Does Chaga Do For The Body? 

This mushroom contributes various benefits to the body. Researchers have extensively studied its potential, especially in combating cancer[4]. Additionally, it contains antioxidants and nutrients that support overall health[5]

Can Chaga Be Put in Coffee? Absolutely!

Currently, mushroom coffee and tea are gaining popularity. Interestingly, during World War I and World War II, people indeed used Chaga mushrooms as a coffee substitute due to the scarcity of coffee. The practical choice arose from its availability in the wild and its coffee-like flavor, making it a viable alternative during those times of limited resources.


Although further research is necessary, Chaga mushrooms have already shown potential for various health purposes.

Health Benefits

1. Cancer-Fighting Properties

One of the most intriguing health benefits of Chaga lies in its potential to combat cancer. Studies suggest that it contains compounds like betulinic acid and polysaccharides, which may inhibit tumor growth and stimulate the immune system to fight cancer cells effectively. 

They have shown promising results in both animal and test-tube studies, indicating their potential to prevent and slow down cancer growth. For instance, in a study involving mice with cancer, Chaga supplements led to a significant 60% reduction in tumor size.

Moreover, test-tube studies have demonstrated that this mushroom extract can inhibit cancer growth in various human cells, including those in the liver, lung, breast, prostate, and colon. This anticancer effect is attributed, at least in part, to the high antioxidant content found in them, which helps shield cells from damage caused by free radicals[6].

It’s important to note that while these findings are promising, further research with human studies is necessary to establish stronger conclusions about Chaga’s potential as an anticancer agent.

2. Boosting the Immune System

They are rich in beta-glucans, which are known to enhance the immune system’s functionality. And they have the potential to support the immune system by aiding in the regulation of cytokine production, facilitating better communication among cells. This support could be beneficial in combating infections, ranging from minor colds to severe and life-threatening illnesses.

During an illness, the body relies on inflammation to fight off the invaders. However, there are instances where inflammation shifts from a short-term defense to a chronic health issue.

Inflammatory-linked illnesses, especially chronic conditions like rheumatoid arthritis, are associated with this persistent inflammation. Interestingly, recent research suggests that even conditions not typically considered inflammatory, such as depression, may be partially influenced by chronic inflammation[7].

Regular consumption of Chaga tea or extracts may help fortify your body’s natural defense against infections and illnesses.

3. Lowers Blood Sugar

These mushrooms boast an impressive ORAC (Oxygen Radical Absorbance Capacity) value, indicating their ability to neutralize harmful free radicals in the body. For those who are dealing with insulin resistance, polycystic ovarian syndrome, or Type 2 diabetes, incorporating chaga mushrooms into their routine may offer potential benefits by reducing blood sugar levels and improving insulin resistance.

Various studies have shown promising results, with potential blood sugar level reductions of up to 31%. Notably, a recent study conducted on obese, diabetic mice demonstrated that chaga extract effectively lowered blood sugar levels and improved insulin resistance compared to mice without the supplement[8].

However, it’s essential to highlight that more research, especially on human subjects, is still needed to conclusively determine Chaga’s effectiveness in managing diabetes in humans. Nonetheless, the existing findings indicate the exciting potential of these mushrooms as a natural approach to support blood sugar regulation and insulin resistance.

4. Lowering cholesterol

The high fiber content in Chaga mushrooms may aid in promoting a healthy digestive system by supporting regular bowel movements and optimizing nutrient absorption.

Also, they are rich in antioxidants and have the potential to contribute to lowering cholesterol levels, thereby reducing the risk of heart disease.

A study revealed that Chaga mushrooms effectively reduced “bad” LDL cholesterol, triglycerides, and overall cholesterol levels while also boosting antioxidant levels. Furthermore, there is evidence suggesting that these mushrooms may have a positive impact on increasing “good” HDL cholesterol[9].

5. Anti-Inflammatory Properties

The mushroom contains triterpenoids, a type of compound known for its anti-inflammatory effects. For instance, in an animal study, this mushroom extract was found to effectively reduce inflammation caused by ulcerative colitis. The researchers discovered that the extract suppressed the expression of chemical mediators responsible for inflammation in the colon.

This finding is highly significant because these chemical mediators intensify inflammation and perpetuate the inflammatory response. By inhibiting their expression, the extract can effectively alleviate inflammation, offering potential therapeutic benefits[10].

6. Potent Antiviral

This mushroom exhibits antiviral abilities against several viruses. A scientific study from 2015 revealed that chaga extracts have an antiviral effect on human immunodeficiency virus (HIV) type 1.

Moreover, animal studies have demonstrated its potential against the hepatitis C virus. In just 10 minutes, the extract reduced the infective properties of the hepatitis C virus by 100-fold using animal cells[11].

Ongoing research continues to explore its antiviral properties, suggesting that this mushroom holds great promise for the development of new antiviral drugs.

How to Make Chaga Tea

Making Chaga tea is a delightful and rewarding process. To prepare the mushroom tea, you have two options. First, use roughly 10 grams of whole mushroom chunks. Alternatively, grind the chunks into powder using a coffee grinder, and take about two teaspoons of the mushroom powder. Whichever method you choose, rest assured it’s a simple beverage you can easily make at home. 

Here is the step-by-step on how to make it:

  1. Gather Your Chaga: Start by sourcing high-quality Chaga mushrooms, either in the form of raw chunks, powder, or an extract from a reputable supplier.
  2. Prepare the mushroom: If you have raw Chaga chunks, break them into smaller pieces using a mortar and pestle or a grinder. For the mushroom extract, follow the manufacturer’s instructions for dosage.
  3. Boil Water: Bring clean, filtered water to a boil in a pot or kettle.
  4. Add the mushrooms: Once the water reaches a rolling boil, add the Chaga chunks or the mushroom powder, or extract to the pot.
  5. Simmer: Reduce the heat to low and allow the mushrooms to simmer for at least 5 minutes.
  6. Strain and Enjoy: After simmering, strain the liquid to remove any remaining mushroom pieces, and your Chaga tea is ready to be savored! Feel free to sweeten with honey or add a splash of your favorite plant-based milk for added creaminess.

Potential Risks and Side Effects

While Chaga may offer an array of health benefits, it’s essential to be aware of potential risks. This mushroom contains a significant amount of oxalates, which have the potential to bind to calcium during digestion[12]. This may be a concern for those who have a history of kidney stones or kidney-related issues. If you have such conditions, it’s best to consult a healthcare professional before adding Chaga into your routine.

Who Should Avoid Taking Chaga Mushrooms?

  • People on insulin or with diabetes, may impact blood sugar levels and pose risks.
  • Those on blood-thinning medications, with bleeding disorders, or preparing for surgery, contain a blood clotting-inhibiting protein.
  • People with autoimmune diseases can increase immune system activity and may require medical advice before use.
  • Women who are pregnant or breastfeeding, as there is no research on its safety for them.
  • Anyone seeking Chaga supplements should remember to buy from reputable sources since it is not monitored by the FDA.

What Precautions Should Be Taken When Using Chaga Mushrooms?

  • Document any side effects from Chaga use and seek medical attention if experiencing trouble breathing, changes in heart rate, or loss of consciousness, as these may indicate an allergic reaction.
  • Continue taking all prescribed medications, as are not a substitute for traditional medication.
  • Avoid combining Chaga with other herbal supplements unless advised otherwise by a doctor.
  • Inform your doctor about all medications you are taking, as may affect the effectiveness of certain drugs.


Chaga’s safety and proper dosage remain unexplored through studies. If you have a bleeding disorder, autoimmune disease, take blood thinners, or are pregnant/breastfeeding, be cautious as unwanted side effects may arise. For your well-being, it’s essential to seek professional advice before considering chaga.
