Siberian chaga mushroom appears as a black mass on birch trees, dead or alive. Occasionally, it may also be seen growing on hornbeam, ash, elm or beech.

In Europe and Asia, chaga has been used for centuries to treat cancers of the heart and liver, digestive ailments, and tuberculosis. [121]

The traditional use was to peel the black skin of the mushroom and then boil it into a tea. Being a compact and easily portable medicinal made it very valuable to healers throughout history.

Modern scientific research has focused on chaga’s anti-cancer properties. In Russia, it has been approved to treat cancers of the breasts, cervix, stomach and lungs since 1955. [122]

A modern study conducted in 1998 showed that chaga extract does indeed inhibit the growth of cervical cancer cells under laboratory conditions. [123] Another study from the mid-90’s found the active compound betulin to cause growth inhibition and death of melanoma cells, also in lab. [124, 25]

Other research papers also confirm that some of the active compounds of chaga help retard the growth of cancer cells. [125, 126]

Betulin is a medically active compound from the birch tree that gets concentrated in the black outer skin of the chaga mushroom, which has been found to contain 30% betulin, [127] whereas the inside of the chaga mushroom contains fungal lanostanes. It would therefore be suggested that chaga tea is better made from the whole mushroom, including the black skin.

The best chaga extracts are made not only from the whole mushroom fruit body but also the mycelia (“roots”), which contain more medically active protein compounds than the fruit bodies.

Other research has found chaga to possess powerful anti-viral properties. In 1996, two studies published results of inhibitory effects on both influenza virus [127] and HIV. [128] Considering the nature of viruses, the most likely scenario is that chaga works on viruses by enhancing the body’s own immune system, a theory confirmed by a paper published in 2002 and another in 2005. [25, 129] The same mechanism may explain the reported anti-inflammatory effect of chaga. [130]

Furthermore, alcohol extract of chaga mushroom has been found to lower blood sugar levels. [131] Chaga also demonstrates significant antioxidant properties that help protect the genetic integrity of the cells. [132, 133]

As an interesting anecdote that does not relate to human health but demonstrates the curative power of the Chaga mushroom, Paul Stamets mentions a Quebec arborist who uses a chaga poultice to cure chestnut blight. It not only cures the infection but the tree even becomes blight resistant after treatment. [134]

Reishi is frequently prescribed in Traditional Chinese Medicine as a panacea. It is widely used by both laymen and professionals in the Orient as a treatment for things as innocuous as stress or weight loss to more serious conditions such as arthritis and even cancer.

One of the strongest proponents for the use of reishi as a medicinal mushroom is Dr. Fukumi Morishige. He works with the Linus Pauling Institute of Science & Medicine on treating cancer with reishi.

Re-printed in the Chinese Traditional Medicine Part III was a speech by Dr. Morishige that included the case studies listed below.

Being a native of Japan, Dr. Morishige was familiar with reishi before becoming aware of its potential in cancer treatment. But his attitude was essentially the same as any other trained medical professional. He believed it might have some marginal effect on certain non-terminal conditions but dismissed any claims regarding cancer as exaggerated. That is, until two of his cancer patients related their stories of using reishi to self-remediate their conditions.

The first case he encountered was a woman in her late 30’s with lung cancer. A number of hospitals had told her the cancer was too advanced to be treatable. There had also been secondary complications in the form of edema of the chest. However, when she came to see Dr. Morishige half a year later, all those symptoms had disappeared. The woman insisted her recovery had come as a result of 4 gm of reishi administered daily by her husband.

Next was a young boy with congenital liver cancer. At five years of age, his doctor had told his parents the cancer was terminal and subsequently discontinued treatment. Four years later, the parents took their son to see Dr. Morishige, who was no longer able to find any traces of the cancer. The boy’s parents told Dr. Morishige they’d been administering reishi to their son via his naso-gastric feeding tube. It was after this that Dr. Morishige decided to take a closer look at reishi’s effect on cancer.

The following are five of his case studies using reishi and Vitamin C (for prevention of side effects):

Case 1: A male patient, 70 years of age, had lost consciousness from a 5 cm brain tumor. Dr. Morishige put him on 6 grams of reishi daily beginning June, 1986. By September, he’d come out of his coma, after which he continued taking 3 grams of reishi per day. Six months later, brain scans revealed that the tumor had shrunk. When it had diminished to 1 cm (0.4 in.), the man left the hospital to go home and live with his family.

Case 2: A 50+ female with metastatic lung cancer and hemoptysis (coughing up blood) began a regimen of 6 gm/day of reishi. Six months later, the tumor had disappeared. And whereas before she had experienced severe shortness of breath, she could now effortlessly climb stairs.

Case 3: Patient with breast cancer metastasized to bones was in excruciating pain and unable to move below the head. She was put initially on 9 gm of reishi per day, which was later increased to 20 gm/day. After two months she reported as pain free and was released from hospital after demonstrating progress in her ability to walk.

Case 4: A male patient with rectal cancer and liver metastasis began using 6 gm of reishi per day. After six months, CT scans showed diminished tumor size and patient demonstrated improved general health.

Case 5: A patient with pancreatic cancer and short life prognosis was put on 9 grams of reishi per day, orally, and 30 grams of Vitamin C, intravenously. Twelve months later, he reported that he longer experienced any symptoms and was back to work. He said he’d continued taking 5 grams per day of reishi after leaving the hospital.

Reishi is the most searched medicinal mushroom on the Internet, used in China for at least two millennia as a panacea to alleviate things from everyday nuisances like the common cold or skin disorders to terminal conditions such as cancer.

One of the strongest proponents for the use of reishi as a medicinal mushroom is Dr. Fukumi Morishige. He works with the Linus Pauling Institute of Science & Medicine on treating cancer with reishi.

The following case reports were given by Dr. Morishige in a speech re-printed in the periodical, Chinese Traditional Medicine Part III.

Growing up in Japan as Dr. Morishige did, it was impossible not to have heard of reishi. But he dismissed it as a mild herbal remedy to be used with limited results for non-terminal illnesses, not as a viable option for treating terminal conditions such as cancer. His curiosity arose when two of his cancer patients showed signs of remission, which they themselves claimed were due to their use of reishi.

First was a 39-year-old woman with lung carcinoma. The hospitals she had visited all told her she was too far gone and there was nothing they could do to help her. As a serious secondary complication, she also exhibited chest cavity edema. None-the-less, by the time she had her first appointment with Dr. Morishige, the symptoms of her illness had disappeared. The woman credited her recovery to the use of reishi, which her husband had administered to her at 4 grams per day.

After that, there was the case of the young boy with congenital liver cancer. Four years before he came to see Dr. Morishige, the boy’s original doctor had sent him home with his parents, claiming the condition was terminal and there was nothing he could do to help. But when Dr. Morishige examined the now 9-year-old-boy, he could find no trace of the tumor. The boy’s parents said they had been giving their son reishi via his naso-gastric feeding tube. This is when Dr. Morishige decided that reishi deserved a closer look.

The following are five of his case studies using reishi and Vitamin C (for prevention of side effects):

Case 1: A patient with a 5 cm (2 in.) brain tumor who had lost consciousness was placed on 6 gm of reishi per day in June of ‘86. By September, this 70-year-old-male patient had emerged from his comatose state. The reishi was decreased to 3 gm per day. Another three months later, December of 1986, scans showed diminishing size of the tumor. After it shrunk to 1 cm (0.4 in.), the hospital released the man to return home and live with his family.

Case 2: A patient with lung cancer, a 50-year-old female, was coughing up blood. Dr. Morishige put her on a daily dose of 6 gm of reishi. In six months, the tumor vanished. The woman, among other things, had regained her ability to climb stairs without suffering shortness of breath.

Case 3: A woman with breast cancer and metastatic bone cancer suffered excruciating pain and an inability to move below the neck. Dr. Morishige started her out on 9 gm/day of reishi and then increased it to 20 gm/day. In two months, the patient was free from pain, able to walk, and was released from the hospital.

Case 4: A man with rectal cancer metastasized to the liver was placed on 6 grams per day of reishi. Six months later, CT scans revealed that the tumor had shrunk. The patient showed improved health.

Case 5: A 60-year-old male diagnosed with terminal pancreatic cancer with a short remaining life expectancy began 9 gm/day of reishi orally, in combination with 30 gm/day of Vitamin C intravenously. One year later, he was completely symptom free and back to work. He continued using 5 gm/day of reishi after being released from the hospital.
