Chaga mushrooms are parasitic fungi that grow on birch trees in forests around the world. They are slow-growing and rock-hard, and they don't have the typical cap and stem form of a mushroom. Instead, they look like black masses or lumps of charcoal. Harvesting Chaga mushrooms is more difficult than harvesting other fungi because they are dense and hard to remove. Foragers should only take what they need and leave enough behind for the ecosystem to recover. It is recommended to use a hand saw to cut only what will be used and to consult a foraging guide or expert for proper identification. After harvesting, the mushrooms need to be cleaned, broken down into pieces, dried, and stored in a glass jar.

Chaga mushrooms are slow-growing and hard, requiring tools like a saw, chisel, and mallet to harvest
Chaga mushrooms are parasitic fungi that grow on birch trees in forests worldwide. They are slow-growing and rock-hard, requiring tools like a saw, chisel, and mallet to harvest. They are often wild-foraged and used to make tea and other wellness products like tinctures and capsules.
When harvesting Chaga mushrooms, it is important to take only what you need and leave enough behind for the ecosystem to recover. It is recommended to harvest Chaga in the winter, as it is believed to have a higher concentration of beneficial compounds during this time, and it is also better for the tree. Before harvesting, consult a foraging guide or expert to ensure proper identification, as Chaga mushrooms can be confused with other similar growths like Tinder Conks.
When you find a suitable Chaga mushroom, use a mid-sized hand saw to cut only the amount you will use. For harder-to-reach spots, a cement chisel and mallet can be used. Be gentle and leave a healthy portion of the mushroom to continue future growth. After harvesting, clean the mushrooms and break them down into smaller pieces using a hammer and chisel.
Finally, the Chaga mushroom pieces can be dried on a dehydrator tray at 100°F for 24 hours or until completely dry. Store the dried mushrooms in a glass jar in a cool, dry place, and they will last for years. To make tea, use a single 0.5-1 oz chunk of dried mushroom per batch.

It is recommended to harvest in winter when the tree is dormant, and the beneficial compounds are concentrated
Chaga mushrooms are slow-growing fungi that parasitise birch trees in temperate and boreal forests worldwide. They are prized for their medicinal properties and have been used for centuries by Siberian and Native American peoples. Chaga has gained popularity in recent times, leading to concerns about overharvesting.
When it comes to harvesting Chaga mushrooms, it is recommended to do so in the winter when the tree is dormant. This is because the beneficial compound in Chaga, betulinic acid, is believed to be concentrated in the sclerotic growth during the tree's dormancy. By harvesting during this time, foragers can maximise the medicinal benefits of the mushroom while also promoting sustainability.
It is important to note that Chaga mushrooms are not the typical cap-and-stem fungi. Instead, they appear as black masses or gnarly burn scars on the tree. To harvest, foragers should use a mid-sized hand saw or a cement chisel and mallet to remove only what they need, leaving at least 25% attached to the tree to allow for regeneration.
When harvesting Chaga mushrooms, it is crucial to follow sustainable practices. This includes leaving enough behind for the ecosystem to recover and only harvesting from trees that are still alive. Additionally, it is recommended to consult foraging guides or experts to ensure proper identification, as there are adverse effects to consuming improperly identified mushrooms.
After harvesting, the mushrooms should be cleaned, broken down into small pieces, and dried at 100 degrees Fahrenheit for 24 hours or until completely dry. Stored in a glass jar in a cool, dry place, dried Chaga mushrooms can last for years and be used to make tea or other medicinal preparations.

Harvesting should be sustainable, leaving 25% attached to the tree for regeneration and only taking what is needed
Chaga is a parasitic fungus found almost exclusively on birch trees throughout the temperate and subarctic regions around the globe. It is also found on other types of trees such as oak, poplar, alder, ash, and maple. Chaga has been used as medicine for centuries, especially for gut health, soap making, and starting fires.
Chaga is a dense, hard growth that isn't easily removed by hand. For larger masses, a mid-sized hand saw can be used to cut only what is needed. A cement chisel and a mallet can also be used in harder-to-reach spots. The number one rule in foraging is to take what you need and leave enough behind for the ecosystem to recover.
Chaga is a slow-growing fungus, and there are concerns about it being over-harvested. To ensure sustainable harvesting, it is recommended to leave 25-50% of the Chaga on the tree. This allows the Chaga to regenerate and continue future growth. Breaking off the large horn is sufficient, without digging into the tree or cutting out the rims. It is also good practice to harvest from different areas and only take what is needed.
Harvesting Chaga from wild sources is considered the best choice, as lab-grown specimens may not have the same chemical makeup. However, due to market demands, wild Chaga is being harvested rapidly, and populations may not keep up. Therefore, it is essential to follow sustainable harvesting practices to ensure the long-term availability of this valuable resource.

Chaga mushrooms are often wild-foraged from birch trees in forests, but can also be lab-grown or purchased online
Chaga mushrooms (Inonotus obliquus) are parasitic fungi that grow on birch trees in forests around the world. They are often wild-foraged, but there are also lab-grown options and the ability to purchase them online. Chaga mushrooms have a unique appearance, lacking the iconic cap and stem of most mushrooms. Instead, they resemble a lump of charcoal or a black burn scar on the tree, earning them names like "black mass" and "sterile conk trunk rot".
When foraging for Chaga mushrooms in the wild, it is important to consult a guide or expert to ensure proper identification, as they can be confused with other similar fungi, such as Tinder Conks (Fomes fomentarius). Chaga mushrooms are slow-growing and rock-hard, and special tools like a hand saw, chisel, or mallet may be required to harvest them. Foragers are encouraged to take only what they need, leaving enough behind for the ecosystem to recover. Additionally, it is recommended to harvest Chaga mushrooms during the winter when the tree is dormant, as this is believed to promote sustainability and may also provide optimal medicinal benefits.
If you are unable to forage for Chaga mushrooms yourself, you can purchase them online from reputable sources such as specialist mushroom websites or try online marketplaces like eBay or Etsy. However, it is important to be cautious when buying wild-harvested Chaga mushrooms due to concerns about over-harvesting and the potential for exploitation. Lab-grown Chaga mushrooms, cultivated on sterile substrates like rye or sawdust, offer an alternative that may be more sustainable and widely available.
Whether you choose to forage, buy online, or opt for lab-grown Chaga mushrooms, it is important to be mindful of the impact on the environment and the potential for over-harvesting. Chaga mushrooms have gained popularity due to their esteemed medicinal properties, but it is crucial to strike a balance between meeting demand and preserving this valuable resource for the future.

After harvesting, the mushrooms are cleaned, dried, and stored in a glass jar, lasting for years for tea or other uses
After harvesting the Chaga mushroom, it is important to clean it thoroughly. Use a brush to scrub the outer surface of the mushroom to get rid of any debris and dirt. Once cleaned, the mushroom needs to be broken down into smaller pieces. Use a hammer and chisel to break it down into 2-3 inch squares or 1/2-1 oz pieces. A cement chisel and mallet can also be used for this purpose.
The next step is to dry the mushroom pieces. Place them on a dehydrator tray and dry them at 100 degrees Fahrenheit for 24 hours or until completely dry. As the mushrooms dry, you may hear cracking and splitting sounds, which is a natural part of the process. Make sure the mushrooms are dried thoroughly before storing them.
Once the mushrooms are dried, store them in a glass jar. Place the jar in a cool, dry location, such as a pantry or cupboard, to ensure the mushrooms stay dry and fresh. Proper storage will ensure that the mushrooms last for years and can be used whenever needed.
With stored Chaga mushrooms, you can make tea or other beverages whenever desired. To make Chaga tea, simply take a 1/2-1 oz chunk of the dried mushroom and follow your preferred tea preparation method. You can also steep 1/2 a teaspoon of Chaga powder overnight in a tea ball. Chaga has been used for its medicinal properties and is known to have a pleasant, grassy finish.
