I have only found a few articles on the Internet.
There is still very little information available about Chaga. The article
by Kahlee Keane appears to have the most reliable information as to how to
prepare Chaga infusion for treatment of what ails you.
Chaga (Inonotus obliquus) A Medicinal Fungus by Kahlee Keane (48kb PDF)
There are some parts that are not clear. She says
"The infusion can be used for up to 4 days."
"...course of treatment, lasting 4 to 7 months, with short breaks if necessary."
These two statements appear to be contradictory. Does the infusion lose its potency after four days? Why a break after 4 days? How long should this break be?
I would be interested in hearing from mushroom hunters who live in Russia and have information on how to use Chaga as a medicine. Are there books or articles, in Russian, that I can purchase? Use the e-mail link, on the bottom of this page, to contact me. I prefer to communicate in English but would be willing to use Russian.
