Top 7 Amazing Health Benefits of Chaga Mushroom

Chaga mushroom helps boost immune system function and fight inflammation. It also has antioxidant properties and helps improve diabetic health. Keep reading below to learn more about its health benefits.


Chaga mushroom (Inonotus obliquus) is a type of fungus and is commonly known as a medicinal mushroom (R).

The mushroom has two distinguishable parts, the sclerotium and fruiting body (R).

It has many therapeutic effects – it can help increase immune system function, stop inflammation, and fight tumors (R).

Chaga can be made into tea, syrup, bath agents, extracts, etc. for medicinal use (R).

Although Chaga is edible, people usually drink tea made from the whole mushroom (R).

In experiments, scientists use either hot aqueous (water) or ethanol extracts of Chaga mushroom. To make aqueous extracts, scientists heat finely grounded Chaga mushroom powder with water, then centrifuge and filter it. For ethanol extracts, the hot aqueous extract is extracted in ethanol and then centrifuged and filtered (R).

Unfortunately, there are limited quantities of Chaga mushroom available in their natural habitat, and artificial production is difficult. Still, current studies show that cultivated Chaga may eventually become an ideal substitute for the wild Chaga (R, R).

One recent study found that Chaga grown on germinated brown rice has enhanced antioxidant and anti-inflammatory effects on mice cells. This new technique can be a beneficial and cost-effective alternative to using wild Chaga (R).

Health Benefits of Chaga Mushroom

1) Chaga has Antioxidant Properties

Oxidative damage to DNA can cause cancer, reduce lifespan, and make your overall health decline (R).

Chaga is used in Japan, Russia, and Eastern Europe for its antioxidant effects (R).

This mushroom helps protect cell components against free radicals and oxidative damage. Both the sclerotium and fruiting body of the Chaga mushroom have antioxidant properties (R, R).

Its phenolic compounds are the active components inhibiting oxidative DNA damage. They can scavenge (combine with and remove) superoxide anions, DPPH and hydroxyl radicals (R).

Compared to other fungi (Agaricus blazei, Phellinus linteus, and Ganoderma lucidum), Chaga has the strongest antioxidant activity (R).

In human lymphocytes, Chaga aqueous (water) extract reduced more than 40% of the DNA damage caused by H2O2 (hydrogen peroxide) (R).

A compound isolated from Chaga protects against Parkinson’s disease-related oxidative stress in human nerve cells (R).

In mice, the antioxidant activity of polysaccharides (complex carbohydrates) from Chaga water extract can protect against the effects of chronic pancreatitis (R).

Gamma irradiation is a method used to eliminating pathogens from food. It can increase the antioxidant properties of foods and natural extracts without any side effects (R).

Irradiation increases Chaga extract’s scavenging activity, its total phenolic compound levels, and overall antioxidant activities (R).

2) Chaga Suppresses Cancer Progression

Extracts of Chaga have demonstrated potent anti-tumor activity. 

Chaga extract inhibits the growth and DNA synthesis of human colon cancer cells (HT-29) (R).

Chaga water extract selectively and significantly inhibited human hepatoma (liver cancer) HepG2 cancer cell viability. It causes cell cycle arrest at the G0 /G1 phase (R).

During the G1-phase arrest of the cell cycle, cells either undergo repair mechanisms or proceed to the apoptotic (programmed cell death) pathway. Cdk activities control the transition to G1/S phase in cells. Chaga extract significantly decreases the expression of different Cdks and stops cell growth (R).

Treatment with Chaga water extract can then induce the cells to undergo apoptosis (programmed cell death), thus preventing tumor growth (R).

Reactive oxygen species and oxidative damage can result in cancer cell formation. However, Chaga’s antioxidative properties can help prevent the generation of cancer cells (R).

In mice with implanted lung cancer cells, continuous intake of Chaga extract slowed tumor progression. After sixteen days of Chaga intake, the average tumor size was 60% smaller than the control group’s tumors (R).

Continuous Chaga extract intake also suppressed metastasis (the spread of cancer to other parts of the body) in the mice (R).

However, the phenolic compounds isolated from Chaga methanol extracts have greater cancer cell toxicity than the Chaga water extracts themselves (R).

3) Chaga Mushroom Helps Protect the Immune System

Polysaccharides isolated from Chaga mushroom are used as immune-boosting agents (R).

Chaga mushroom extract increases blood levels of protective cytokines. In mice, Chaga extract increases IL-6 levels. IL-6 is a protein that increases immune cell formation (R).

Polysaccharides from Chaga mushroom extract stimulated lymphocyte B cell formation in mice spleen cells. This increases antibody production and immune system activity (R).

Chaga extracts can also protect against allergens. It suppressed anaphylactic shock (a possibly fatal allergic reaction) in mice. It also lowered their total IgE levels, which stops immune system hypersensitivity (R).

Both hot water and ethanol extracts of Chaga are able to kill bacterial and fungal cells in cell culture. They also stopped quorum sensing, which is a method that bacteria cells use to activate gene expression. Anti-quorum sensing can help fight against bacterial infection (R).

Chaga mushroom also has anti-viral activities and can help prevent viral infections from occurring (R).

HIV needs HIV protease to make more functional viruses. Water extracts and lignins (organic substances) isolated from Chaga inhibit HIV protease and HIV replication (R, R).

Chaga hot water extract prevents herpes virus entry in Vero (monkey kidney) cells (R).

Chemical compounds isolated from Chaga also inhibited the Epstein-Barr virus (a human herpes virus) in mice cells (R).

In pig cells, Chaga water extract helped kill the hepatitis C virus (R).

4) Chaga Reduces Inflammation

Chaga’s anti-inflammatory effects are mostly due to its ability to prevent nuclear factor kappa B (NF-kB) activation. NF-kB is associated with the expression of several pro-inflammatory genes (R).

Chaga methanol extract is a potent inhibitor of inflammatory cytokines in mice cells. Chaga hot water extract also reduced pain and inflammation in mice after oral administration (R).

In mice, Chaga water extract significantly inhibited mRNA expression of pro-inflammatory cytokines in colon tissues. These results suggest that Chaga mushroom may help treat Inflammatory Bowel Disease (R).

5) Chaga Can Improve Diabetic Health


In diabetic mice, Chaga ethanol extract significantly decreased blood glucose levels. Additionally, the ethanol extract decreased free fatty acids, total cholesterol, and low-density lipoprotein (bad) cholesterol in the blood (R).

It also increased high-density lipoprotein (good) cholesterol and insulin levels in the livers of diabetic mice. This helps prevent high blood sugar levels and diabetic complications (R).

Failure in adipocyte (fat cell) differentiation is one of the many causes of type 2 diabetes. The fat cells of Type 2 diabetic patients are also insulin-resistant (R).

PPARγ suppresses the insulin resistance in fat tissue. It also activates the expression of genes associated with insulin signaling and glucose and fat metabolism in fat cells (R).

In mice fat cells, Chaga water extract increased PPARγ transcriptional activity and helped with fat cell differentiation. This decreased insulin resistance, making it a possible treatment for diabetes (R).

Increased PPARγ activity in fat tissues also helped reduce fat levels in obese mice (R).

Free radicals many also play a role in the development of diabetes. Chaga’s antioxidant properties can help stop oxidative damage and stop the decrease of insulin levels (R).

The anti-diabetic effects of Chaga increases if used in combination with vanadium. In diabetic mice, Chaga extract combined with vanadium decreased blood glucose levels more than Chaga extract by itself (R).

6) Chaga Increases Endurance

In mice, Chaga polysaccharides (complex carbohydrates) increased exercise tolerance. Compared to the control group, mice treated with Chaga polysaccharides swam for a longer period of time (R).

Accumulation of lactate in the body can cause fatigue. Chaga polysaccharides significantly reduced blood lactate levels in exercising mice (R).

Additionally, a lack of energy can decrease endurance capacity. High glycogen content helps prevent fatigue. Mice treated with Chaga had higher glycogen levels in the muscles and liver than mice in the control group (R).

7) Chaga Protects Against Dangerous Blood Clots

Platelet aggregation occurs when platelets (blood cells) clump together in the blood and form clots. Sometimes, platelet aggregation can cause blood clots in veins (thrombus), which can eventually lead to heart attacks or strokes (R).

Ethanol extract from Chaga mushroom mycelia significantly inhibited platelet aggregation in rats. These results indicate a possibility for Chaga to treat or stop thrombus formation (R).


Since Chaga stops platelet aggregation and blood clots from forming, you should not take it in combination with blood-thinning medicines. It can increase the risk of bleeding (R, R).

Chaga can lower blood sugar levels. You should not take Chaga in combination with diabetes medicine because it may cause blood glucose levels to fall dangerously low (R, R).

People with auto-immune diseases should avoid using Chaga because it can cause the immune system to become more active. This can increase the symptoms of some diseases (R).

In one case study, an elderly Japanese woman had oxalate nephropathy after six months daily consumption of Chaga powder. Oxalate nephropathy is a condition where excess levels of oxalate can cause kidney failure. Chaga mushrooms contain extremely high oxalate concentrations, so excess consumption can cause kidney damage (R, R).

Additionally, sclerotium parts of Chaga appeared to have stronger cytotoxic effects against normal cells than cancer cells. This can cause healthy cells to die (R).

Most of the laboratory studies have either been done in human cell culture or animals. More clinical trials are needed to confirm Chaga’s safety and effectiveness (R).
