Chaga Mushroom: What It Is and How to Use It
Chaga is a dark, charcoal-like fungus that grows on birch trees in cold northern climates, including Siberia, Scandinavia, and parts of Canada. It has been used for generations as a folk remedy in Russia and northern Europe, usually brewed into a tea. You can find chaga at William's Natural Foods, 12249 San Pablo Ave, Richmond, CA 94805.

Frequently Asked Questions
What is chaga traditionally used for?
Chaga has been traditionally brewed as a tea in Russian and northern European folk practice, where it was used as a general wellness tonic. In the last decade or so, it has become one of the trendier "mushroom" ingredients in U.S. health food culture. People who buy it are usually looking for a traditional, earthy alternative to coffee or tea.
What does the research say about chaga?
According to Memorial Sloan Kettering Cancer Center, chaga is commonly found on birch trees in cold climates and has been used as a folk remedy in Russia and other northern European countries — but its safety and efficacy have yet to be evaluated in clinical studies. Most of the interesting findings so far come from lab and animal studies, not human trials.
How is chaga usually prepared?
Chaga is most often simmered slowly into a dark, earthy tea, since the tough, woody chunks need long extraction to release their flavor. Some people grind it finer for a stronger brew. The powder form is also commonly stirred into coffee blends or hot cocoa.
Are there interactions I should know about?
Chaga may slow blood clotting, so it can interact with blood-thinning medications and raise bleeding risk — Memorial Sloan Kettering advises talking with a healthcare provider if you take blood thinners such as warfarin. It may also lower blood sugar, which matters for people on diabetes medications. If you take either type of medication, check with your doctor first.
