Heather and Blair from Annanda Chaga have been harvesting Birch chaga and promoting the benefits of chaga mushroom long before Chaga became popular. Annanda Chaga has been recognized as having one of the best reputations in the business and a trusted source of Canadian chaga for almost 10 years.
From our humble beginnings back in 2012 we wrote a heartfelt testimony entitled "Harvesting to Heal" which celebrates our enthusiasm and trials of a small Canadian family company trying to spread awareness about the benefits of chaga mushroom to the world. Consider this blog to be a seasoned update to our initial prologue and shining beacon to those new to the birch tree mushroom Chaga. If you are knowledgeable about chaga consider this blog a welcome refresher which includes some new insights into the world of chaga mushrooms.
What are Chaga Mushrooms?
Chaga is the common name for the fungus, Inonotus obliquus, used to brew chaga tea. Chaga is also commonly known as the cinder conk, and to some mycologists as the ‘clinker polypore’. In chinese cultures chaga is known as Bai Hua Rong or Hua Jie Kong Jun. The Japanese know chaga mushroom as Kabanoanatake. Learn even more in our What is Chaga? page
What Does Chaga Look Like?
Although it is classified as a mushroom, chaga appears as a hard, sharp edged black coloured growth on host trees. It grows on birch trees (Betula papyrifera) nearly exclusively, and only rarely has been found attacking other trees. Chaga Mushrooms may be found on wounded or dying white birch trees in temperate forests around the northern hemisphere. Chaga looks like encrusted black formations; the sterile conk or mycelium grows out of wounds sustained after storms and other impacts that break branches. Chaga covers the tree's wound and protects it from invading microorganisms. The host tree and the Chaga can co-exist for many years and the chaga mushroom can be harvested up to three times over the course of its lifetime if harvested ethically with conservation in mind.

History of Chaga Mushroom
Chaga tea has been used in Russia since the 16th century and was popularized in a 1968 novel, called ‘The cancer ward’ where chaga tea was purported to cure cancer. Chaga tea benefits suggest that chaga is a strong antioxidant and can slow tumor growth. Chaga is also reported to be effective for gastrointestinal cancer, cardiovascular disease, diabetes and arthritis.
Chaga Mushrooms have also been used in Ayurvedic and traditional Chinese Medicine for centuries. Chaga mushroom is often compared to similar fungi like the Reishi, Shitake, Maitake and Oyster mushrooms.
Chaga has been used by many cultures all around the world for centuries and used for prevention and cures for many types of diseases. Widely used in Russia, Poland and other Baltic countries as folk medicine for gastric problems, cancer, tuberculosis and heart and liver issues.
Chaga has been used in Russia as far back as the 16th Century for various cancers, especially tumors associated with angiogenesis (buildup of blood vessels that feed cancerous growths). In Siberia, chaga has been widely known to help treat tuberculosis, liver conditions and stomach problems including gastritis and ulcers. The Khanty people of Western Siberia put the chaga into fire and put the smoldering conk into hot water for use to clean and purify women's genital region after menstruation and birthing.
Also used in Canadian aboriginal culture First Nations people have been using Chaga for Centuries as well. Cree healers call chaga Poashkan or Wiskakecakomikih. Wisakecak is a mythological being who threw a scab mistaken for a piece of dried meat against a birch tree and tried to ingest it. Chaga produces a sweet smelling incense and is often used in smoking pipe ceremony. Used by the Cree and other native nations as a form of Moxibustion treatment to stimulate the body’s energy meridians.
What trees does chaga grow on?
There is a lot of confusion as to what trees chaga grows on. Chaga should only be harvested from living white or yellow Birch trees. Never harvest chaga from dead or fallen trees, also known as 'dead chaga' will appear black inside and out and will most likely contaminated with mycotoxins.
Where does chaga grow?
Avoid taking chaga from trees that look similar to Birch, specially Aspen, Popular, Beech trees. Chaga from these species of trees does not contain the highly prized betulinic acid which only comes from Birch and does not offer the same medical quality as Birch Chaga does.

How to Harvest Chaga
When harvesting Chaga always leave 1 to 2 inches behind so that the tree will remain protected and the birch chaga will regrow. Chaga mushroom can grow on the host tree for up to 20 years; if harvested properly you can harvest 3 to 5 times during the host tree's lifespan.
The chaga fungus is not a fruiting body but a sterile non-sexed conk. The Chaga and the host tree live together in symbiosis. The chaga extends the life of the host tree so that the fungi can thrive. Only years after the host tree dies will the chaga mushroom reproduce. When harvesting chaga always leave enough chaga behind so that the chaga fungus is flush with the exterior of the tree. This will ensure that the tree remains protected against any future infections.
Improper harvesting of Chaga is a big concern. If all the Chaga is taken from the host tree, the tree will succumb to infection or disease and will die within a few years. The Chaga will not regrow and will never have the opportunity to fruit and reproduce.
Tips on how to harvest chaga
Chaga often grows higher up on the tree so quite often one would need to climb up. Deer stands work great without harming the tree. Harvesting chaga from birch trees located higher up is preferred and is more potent.
- Do not harvest chaga from fallen or dead trees
- Do not harvest Chaga that has fallen to the ground.
- Do not harvest chaga that is moldy or shows signs of visible contamination or is littered with bugs or larvae.
- Do not harvest chaga that is black both on the interior and exterior - (dead chaga)
- Do not harvest chaga from trees growing on or immediately near contaminated lands, mills, hydro-cuts, industry etc.
- When harvesting chaga it should be at least the size of a large soft ball or much larger. The bigger the better.
- Harvesting chaga with the proper tools You can use an axe or, large sharp knife or machete, hammer & chisel or battery operated reciprocating saw because it is really very difficult to separate the outgrowths from the trunk.
- Always leave 1-2“ of chaga on the tree, when harvesting chaga never dig all of it out it will kill the tree and the inner core deep within the tree has no medicine.
- Respect the tree and nature - harvesting chaga should be done with respect for nature; always leave some behind so that the natural cycle can continue.
When to harvest Chaga?
There are many theories as to when is the most appropriate time of year for harvesting chaga. Chaga grows all year long for several years on the host tree. Keeping the host tree in mind it is our belief that the only time you should not harvest chaga is in the spring time. When the host tree awakens from its winter dormancy, the inner sap begins to flow and new buds are forming. Winter is always a good time to harvest because chaga is easier to spot against snowfall, the trees are dormant, and there is less foliage to hinder your journey threw the woods. Unfortunately, one does need to navigate through some heavy bush and often very deep snow drifts and bitter cold.
How to process chaga - How to Dry Chaga
- Chaga has a black outer crust, leave the back outer crust – do not discard or file off.
- You can use an air compressor to blast away any bits of dirt, bark, needles etc. or a soft natural bristle brush
- Chaga must be dried right away after harvesting or put into a deep freezer for later drying and processing.
- Fresh chaga mushroom is very wet and is easily prone to mold; thus it should not be dried in an area that is too damp, cold or poorly ventilated.
- One should not attempt to dry chaga more quickly in a hot oven; otherwise, it will lose most of its biologically active nutrients
- Dry chaga in a warm, well-ventilated place. As well, it is necessary to cut the fresh chaga into pieces that are no more 1-2 Inches to allowing it to dry until the pieces become hard and crumbly.
- Drying chaga in a a commercial food dehydrator works great. Check the moisture content of your chaga with a moisture meter and dry until its ready below 10% moisture content.
- Store dried chaga in air-tight sealed containers away from direct sunlight.
- Stored properly chaga can remain potent and last for several years.
Various styles and grinds of Chaga Mushroom
The Chaga Mushroom is known as the "King of Medicinal Mushrooms." Considered by many cultures as one of the most powerful healing plants on Earth and used for centuries in Traditional Chinese Medicine. After it as been harvested, the Chaga needs to be air dried and broken into chunks or ground into a course or fine powder. The outer cell walls of Chaga are protected by chitin and need to be broken down or extracted. Over the centuries chaga has been extracted by steeping it in hot water to make a medicinal Chaga Mushroom Tea or matured into a potent Chaga Tincture by soaking it in alcohol. Both the hot water and alcohol methods over long periods of time help to dissolve the chitin protecting the valuable nutritional contents inside the Chaga. Chaga can be consumed directly as a Chaga Mushroom Powder. Chaga powder can be added to soups, stews, smoothies etc. to add nutritional value to everyday meals, and still maintain high concentrations of mushroom polysaccharides. It is still advisable to use some means of extraction however to achieve the most benefit from the mushroom.
Chaga tea is the most popular grind of chaga as it offers several ways in which you can make chaga tea.

Chaga mushroom capsules
Chaga in capsule or instant form is indeed easier to take, however most of the benefits are destroyed during the manufacturing process. Chaga, like most natural forest medicines must be taken in its raw unaltered form to heal us. As an herbal decoction or ‘tea’ chaga should be steeped at 80c or below or extracted with pure grade alcohol specifically designed for herbal extractions.
Why Most chaga capsules are fake
Chaga mushroom benefits
Chaga has been found to contain a host of pharmacologically active compounds that beneficially affect human health (Zjawiony 2004, De Silva et al. 2013). The biological activity of the chaga fungus is mainly due to the presence of several polysaccharides, constituting the following sugars: rhamnose, arabinose, xylose, mannose, glucose, and galactose (Hu et al. 2017). In the last decade, several studies have reported biological activities of chaga mushroom such as anticancer, antioxidation, anti-inflammatory, antidiabetic and enhancement of immunity (Choi et al. 2010). Remarkably, a number of studies demonstrates little or no side effects during use in disease treatment (Wasser 2002, Choi et al. 2010, Elkhateeb et al. 2019).
- Chaga mushrooms are a powerful antioxidant and source of superoxide dismutase (SOD) which halts oxidation, especially free radicals like singlet oxygen responsible for damaging tissues.
- Chaga mushrooms are a source of 200 + phytonutrients
- Chaga Contains significant amounts of riboflavin and niacin
- The Chaga Mushroom contains B and D vitamins, flavonoids, phenols, copper, calcium, potassium, manganese, zinc iron and enzymes
- Chaga is one of nature's riches sources of the minerals rubidium, potassium, cesium and germanium; everything the body needs to remain alkaline
- Chaga is great source of pantothenic acid which aids the adrenal glands and digestive organs
- The Chaga Mushroom has been used for improving cognitive function and memory loss. Chaga Mushroom stimulates cognitive functions and helps to improve memory and learning - Japan Study reveals
- Chaga is a vital source of plant based sterols which reduce bad LDL cholesterol, stabilizes blood pressure, increases metabolism and aids the endocrine system
- The Chaga Mushroom that comes from Birch trees are also rich in Betulinic Acid which as been used to to shrink some types of cancerous tumors.
Chaga antioxidants
Various compounds extracted from Chaga have been reported to exhibit an antioxidant activity. Nakajima et al. (2007) illustrated superiority of the chaga antioxidant activity (both superoxide and hydroxyl radicals scavenging activities) of a hot water extract of Chaga in comparison with those of other medicinal fungi namely Agaricus blazei mycelia, Ganoderma lucidum and Phellinus linteus. Further determination of the chaga antioxidant potential of the isolated fruiting body (spore-generating mass) and Sclerotium (Chaga) revealed that an 80 % methanolic extract of the fruiting body had a higher potential than that of Chaga decoction.
Chaga benefits - Antidiabetic chaga
Chaga extracts function as an antidiabetic through the lowering of blood glucose levels. Polysaccharides, which represent one of the main components of chaga mushroom extract are capable of inhibiting alpha-glucosidase, a carbohydrate-hydrolysing enzyme. Hence, chaga mushroom extract may act as a hypoglycemic agent by retarding glucose absorption in digestive organs and thus preventing hyperglycemia following meals (Chen et al. 2010, Lu et al. 2010, Wang et al. 2017). Sun et al. (2008) and Xu et al. (2010), reported that polysaccharides of I. obliquus are capable of reducing glucose, triglycerides, fatty acids, and cholesterol levels in blood.
Benefits of chaga tea anti inflammatory
Causes of inflammation can range from wounds, burns, infections, stress, free radicals, radiation and allergies, to immune system disorders. Drugs reducing inflammation are called anti-inflammatories. Van et al. (2009) tested several different types of extractions from Chaga, for their ability to reduce inflammation. All of those tested significantly inhibited inflammation, including a water-based polysaccharide extract and an ethanol-based extract. Kim et al. (2007) and Choi et al. (2010) found similar results with ethanol extracts.
Benefits of chaga - Anticancer activity of chaga
The anticancer activity of chaga extract is perhaps the most widely reported benefits of chaga and that which has received the most interest. The cytotoxic and/or apoptotic effects of chaga mushroom tincture have been demonstrated in numerous in vitro studies in cancer cell lines, including the human colon cancer cells and the human hepatoma HepG2 cells (Youn et al. 2008). Polysaccharides isolated from chaga mushrooms have a direct antitumor effect due to protein synthesis inhibition in tumour cells. Also, polysaccharides derived from the mycelium of chaga mushroom function by activating the immune system. Due to the limited toxicity of these substances, both chaga tincture as well as isolated and purified chemicals may be a good alternative to current chemotherapy and have potential for a role in cancer prevention (Staniszewska et al. 2017).
