Chaga and cancer: scientific research

Cancer is a word that scares many people. Despite modern technologies, cancer is fatal for at least 25% of patients. Therefore, you need to use all available means in the fight against it.

Chaga can help on the way to recovery (Inonotus obliquus). This birch parasite has been used in official medicine to fight cancer for more than two centuries. It is included in the modern pharmacopoeia of many countries and is part of the comprehensive treatment of cancer.

What types of cancer does chaga help

Interestingly, the mushroom has no selective action. It is quite effective for malignant tumors in any organs. Chaga successfully cures cancer:

  • Salivary glands.
  • Lungs and bronchi.
  • Intestines.
  • Esophagus.
  • Stomach.
  • Breast.
  • Liver.
  • Skin.
  • Pancreas.
  • Prostate gland.
  • Bladder.
  • Larynx.

Polypore also helps with malignant blood tumors-leukemias.

The stage is also irrelevant. There is a positive effect at all stages of the disease. There are reports of complete recovery even of hopeless patients.

How does Inonotus obliquus affect cancer cells

The main active components of Inonotus obliquus that can affect malignant cells are lanosterol and inotodiol. The mycelium contains about forty of these triterpene compounds.

The main effect is cytostatic- substances don’t allow the tumor cells to divide. Some compounds also have cytotoxic properties- they cause the death of malignant structures. To date, several mechanisms of action of chaga have been found:

  • Inonotus obliquus stops the division of tumor cells and causes their apoptosis – natural death and dissolution. This is due to the fact that chaga increases the activity of the dissolving enzyme caspase and triggers a cascade of reactions involving Bach proteins responsible for cell death.
  • Polysaccharides contained in the mycelium, are activators of the immune b -cells and macrophages. And those, in turn, attack the tumor and destroy it.
  • Mushroom extract suppresses in malignant formations cyclins and cyclin- dependent kinases-substances that regulate the process of division. The cancer stops growing in size.
  • Fungus includes hormone-like compounds – sterols, which stop the transcription of DNA and block the active growth of malignant tumors.

In addition to specific effects on the tumor, the effect of polypore is noticeable due to the support of the nervous system and reducing stress, reducing inflammation, regulating the processes of metabolism and hematopoiesis. Betulin and betulinic acid, which the parasite receives from birch, prevent fungi and viral infections from developing. This is very important for cancer patients who are weakened by therapy.

What scientific research has been done

The first serious studies of Inonotus obliquus were conducted in Russia in the middle of the last century. In 1962, the employees of the Komarov Botanical Institute identified the active components of the fungus that affect tumors. This marked the beginning of deep research on the composition and mechanisms of action of the chaga.

The practical use of the polypore began much earlier. In 1862, at a meeting of the Society of Physicians of St. Petersburg, it was reported that the patient with advanced cancer of the lips was fully recovered when taking chaga. In 1882, the Russian doctor Leonard Froben described a case of curing a patient of parotid cancer with a decoction of a mushroom.

Currently, the most active research on wood parasite is carried out in Korea and Japan. Since 2018, chaga has been studying the antitumor properties in France and Iraq.

  • In the 1950s and 60s, the effect of chaga extract on patients with stage 4 cancer of various localization was studied at the Komarov Botanical Institute in St. Petersburg. The tests involved 500 patients. The results are published in the book “Chaga and its therapeutic use in stage IV cancer” edited by P.K. Bulatov.
  • The antitumor effect of polysaccharide from chaga mycelium was confirmed at the Department of Biotechnology at Yonsei University in South Korea in 2005 (
  • In 2008, Korea studied the effect of tinder extract on human hepatoma (
  • In 2009, the Department of biotechnology at Daegu University in Korea conducted a study of the effect of water extract of chaga on colon cancer. (
  • In the same year, the University of Pharmacy Osaka isolated and studied the cytotoxic activity in leukemia of lanaostane triterpenoids of the fungus. An article with the results was published in Bulletin of Osaka University of Pharmaceutical Sciences 2009, 3).
  • Employees of the Korean Gachon Institute of Pharmaceutical Sciences in 2015 reported the antitumor effect of chaga ergosterol peroxide on colorectal cancer. (!).
  • In 2018, the effect of 10 bioactive compounds of birch fungus on the liver and malignant structures was studied at the University of Sulaimani in Iraq. This was reported in Int J Med Mushrooms 2018; 20 (6): 507-516.
  • At the same time, the University of Normandy in France was studying the effects of betulin and betulinic acid on human lung cancer (Integr Cancer Ther. 2018, 17 (3): 832-843).

This is only a small part of the research. All of them confirmed the effectiveness of the birch parasite. The use of polypore in oncology is also mentioned in other scientific works and books.

Clinical trials conducted on mice and rats, to which the tumor was specially transplanted, showed that more than 60% of the animals are completely cured of oncology after taking chaga. Metastases appeared later in the subjects and their number per group was 0.17%, as opposed to 14% in the control group.

Results of chaga taking

Doctors recommend to consume the mushroom in the complex treatment along with other anti-cancer agents. Mushroom preparations are useful for inoperable cancer of the fourth stage. Patients supplementing therapy with polypore broths live two to three times longer than those who don’t accept them. The chaga gives a good effect during chemo- and radiotherapy at stages 1-4.

In general, the mushroom significantly increases the effect of treatment:

  • Normalizes appetite.
  • Helps to gain the weight.
  • Improves internal physiological processes.
  • Tones the central nervous system, especially the vegetative department, which is responsible for the work of internal organs, vascular contraction, and the release of hormones.
  • Reduces the level of pain, and after 1-1.5 months it completely stops it.
  • Protects the liver from toxins (eliminates up to 84% of damage to hepatocytes).
  • Promotes wound healing after surgery.
  • Normalizes the release of enzymes by the pancreas, stomach.
  • Restores the number of immune cells after irradiation.
  • Protects against ulcerative colitis.
  • Slows down the spread of metastases.
  • Reduces tumor volume.

The quality of life of patients is increasing, many of them are recovering.

How to take polypore from oncology

The effect of chaga treatment depends on the dose and duration of treatment. In oncology, mushroom preparations are taken for a long time – from five months or longer. Research shows that even if you use the mushroom for more than 12 months, there are no negative consequences for the body. Therefore, you can be treated yourself without fear of harming yourself. The mushroom is used for:

  • Preventions.
  • Prolonging the life of inoperable patients.
  • Better tolerability of chemotherapy.
  • Recovery at any stage of oncology.
  • Improving the quality of life and pain relief.
  • Recovery after aggressive treatment.
  • As a post-recovery support.

The effect can be seen after 3-4 weeks. Medication is used daily up to three times a day in the form of:

  • extracts,
  • external lotions,
  • aerosols (for lung and laryngeal cancer).

One of the simplest ways of home treatment is to drink chaga tea. It is easy to prepare and can be consumed instead of the usual drinks. This is guaranteed to reduce the risk of getting sick and support the body with existing tumors.
