1] According to a report in the US Natl. Library of Medicine (NIH), "the analysis of the organic extracts of Chaga revealed birch compounds such as betulin, betulinic acid, and a characteristic fungal molecule inotodiol... observations allow us to consider the therapeutic interest of the Chaga, its chemical complexity, and to emphasize the interest of continuing to investigate mycotherapy potential by associating both chemical and biological approaches." 
We originally learned about Chaga mushroom and its medicinal qualities from our prior interview with Jim Hunt and his solutions to treat his own prostate cancer. Debbie shared her experiences, her research and personal understanding about how this unique treatment solution works. She employed her talents as a clinician (RN) and a health advisor to cancer patients who showed tremendous success using the mushroom for some of a wide range of health issues.
Experts in Chinese medicine are well aware of chaga for their patients, as it has been around for thousands of years in other cultures like Scandinavia, Russia, China etc. Even an article from Sloan Kettering mentioned that chaga mushroom is being used in association with Covid, managing influenza type B like a Tamiflu/ They see it as a preventive to help your immune system and keeps you strong and healthy.
From all the global research, chaga mushroom has an exceptional amount of Betulinic acid which has been found to shrink tumors. It also provides the ability to detox, and many vital supportive nutrients like potassium, zinc, vitamin D- helpful supplements to complement our inactive lifestyle. The way I understand it, chaga mushroom has been recognized to actually change the mitochondria in the cancer cell, where its compounds can actually break down the outer shell up the cancer cell.
The active constituents of chaga are thought to be a combination of amino acids, beta glucans, betulinic acid, calcium, chloride, copper, dietary fiber, enzymes, flavonoids, germanium, inotodiols, iron, lanosterol, manganese, magnesium, melanin, pantothenic acid, phenols, phosphorus, phytonutrients, polysaccharides, potassium, saponins, selenium, sodium, sterols, trametenolic acid, tripeptides, triterpenes, triterpenoids, vanillic acid, vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin D2 (ergosterol), vitamin K, and zinc.

Betulinic acid is a naturally occurring pentacyclic triterpenoid which has antiretroviral, antimalarial, and anti-inflammatory properties, as well as a more recently discovered potential as an anticancer agent, by inhibition of topoisomerase.
HOW DO YOU FIND IT?
With my background as a registered nurse, I made suggestions based on their blood work and their current symptoms & diagnoses. They integrated the chaga information I provided with those from their practitioners as part of a personal integrative health plan. I would often check in with many of them from time to time to see how they were doing, and I found a lot of incredible success stories to attest to the efficacy of this tea.
You start with four or five 2 inch cubes, fill up a Crock-Pot that should make enough tea to fill an eight quart crock pot twice. A rule of thumb is to boil just however many that can fit in the cup of your hand. It gets to be the color of dark maple syrup, and you can drink it warm or cold. People can sweeten it if they choose to. I suggest a true stove top boil, better than microwave to get the most out of it. I suggest two cups a day. Before I started working with so many cancer patients, I used this for DIABETES because it stabilizes blood sugar and blood pressure.
There's different ways of extracting the benefit. Jim Hunt’s version was to brewed it, using four or five mushrooms in eight quarts of water, put it in the fridge then he took it to work every day in his cooler. In order to get all of the properties out of the chaga mushroom, like the BETULINIC ACID, the POLYPHENOLS, the ANTIOXIDANTS and all the different properties that are in it, it has to leach out into the water. So the only way to make that happen is to slow brew it with a continual heat.
Another way to use it is to grind it into a powder and make it into a tincture with alcohol. It sits for months, and you can put it under your tongue- like any other kind of a tincture. But for most of the people that I've spoken to (those who are sick), they need the optimal benefit of the tea. And for that is definitely slow brewing it and drinking it out of a cup, like a cup of coffee or tea. That is definitely the best way to do it.
