What is Chaga?
Although it's not much to look at, Chaga, or the "King of Medicinal Mushrooms" as some like to call it, is a very special medicinal mushroom that is gaining popularity in the west for its health benefits and appealing taste in the form of chaga tea.
These benefits have long been known in the East, where Chaga has been used for centuries by people in Siberia, Russia and other parts of Asia.
What does it look like and where does it come from?
What we know as "Chaga" is actually the dense black mass of mycelia (roughly 10" to 15" in size) that appears on the outside of birch trees infected with the non-toxic parasitic fungus Inonotus Obliquus.
The hard & cracked black exterior, which looks like burnt charcoal, is called the sclerotium (Fig 1).
The interior is softer and has a rusty yellow-brown color that can be seen when it's removed from the birch tree and broken into chunks (Fig 2).
In general, Chaga Mushrooms are mostly found in very cold habitats and grow predominantly on birches.
More specifically, Chaga grows wild in the birch forests of Russia, Korea, Eastern and Northern Europe, Northern areas of the United States and in Canada.
What are the Health Benefits?
Although research is ongoing, credible studies have shown that the Chaga Mushroom may provide several health benefits, including:

How do you Consume it?
Chaga has a naturally occurring vanillin, the same as found in the vanilla bean. Therefore, it takes on a slight hint of vanilla flavor when consumed as a tea and doesn't taste anything like a regular mushroom.
There are several ways to consume Chaga, but hot water extraction (e.g. Chaga Tea) is the most common and simplest way to enjoy it.
However, a quality dual extract is the only way to extract all of the healthy bioactive ingredients that are locked inside. This method typically combines both hot water and alcohol extraction methods, but can vary in sophistication.
How Do You Harvest and Prepare Chaga?
Chaga should only be harvested from living trees and great care should be taken not to damage the tree or over-harvest the chaga.
If you're feeling adventurous and wish to harvest Chaga for yourself, read our guide on How to Harvest Chaga to learn more.
After harvesting, the Chaga is dried and then broken into small chunks or ground into a powder for tea.
When prepared at home, the chunks are typically brewed/steeped in hot water to make a medicinal Chaga Tea, or mixed with alcohol and left to mature into a powerful Tincture.
The raw powder can also be added to smoothies, soups, stews, etc., to add nutritional value to everyday meals.
Chaga Life Cycle
Most typically, well-formed sclerotia are found on birch trees older than 40 years, however, the fungus infection starts much earlier.
Once infected, it takes about 3 to 5 years until the Chaga can be harvested. During this time, the mushroom is actively drawing nutrients and vitality from its host and utilizing them for its own development.
Once harvested, Chaga can grow to a harvestable size again in about 3 to 10 years, and this cycle can be repeated until the tree dies.
The time from initial infection to tree death can vary with the number of infections and the tree's resistance, but is typically around 20 years.
It's important to remember that removing the Chaga does not stop the infection.
The Future of Chaga
As more & more respected institutions, such as the Memorial Sloan Kettering Cancer Center, produce credible and detailed studies into the medicinal benefits, the more people will discover this special mushroom.
Furthermore, improvements in the extraction techniques from producers such as Oriveda will help consumers get the most out of it's numerous health benefits.
